From fde83c7cdb76f3eac06117739162f108ba07b8b1 Mon Sep 17 00:00:00 2001 From: hosein-ul Date: Mon, 22 Jun 2026 09:16:27 +0300 Subject: [PATCH 01/69] feat(registry): read WrappersRegistry on-chain instead of hardcoded list MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Addresses the top-priority audit finding (AUDIT_REPORT.md Finding #1): the app previously rendered wrapper pairs from a static `KNOWN_WRAPPERS` map and never read the registry. As a result, two real pairs were already invisible to users at audit time — Sepolia `ctGBP` (restricted, 0x167D...A208) and Mainnet `cbbqTGBP` (0xBA4c...6762). Changes: - New `src/lib/registry.ts` exporting `useRegistryPairs(chainId)`, which wraps `useListPairs` from @zama-fhe/react-sdk with `metadata: true` and maps results into the existing `WrapperPair` shape. Falls back to the hardcoded snapshot when the wallet is disconnected or chain-misaligned, with an `isFromCache` flag so the UI can disclose stale data. - Adds `isValid` and `underlyingRawSymbol` to `WrapperPair`; symbols are normalized (strip `Mock` suffix) so live and cached lists round-trip through the same identifiers. - `isMintablePair(pair)` helper detects mock underlyings via the raw symbol; the faucet now filters by it, so the Sepolia restricted `ctGBP` is excluded automatically once the registry is read live. - Registry page: skeleton rows while loading, "Showing cached snapshot" banner when offline, "Show revoked" toggle, "Revoked" badge per row, and Shield/Unshield disabled on revoked pairs. - Wrap selector excludes revoked pairs; Portfolio keeps them so a user can still decrypt + unshield a stale position. - Deletes `src/lib/registry-abi.ts` — its function names (`getAllWrappers`, `getWrapperCount`, etc.) did not match the real `WrappersRegistry` ABI and it was unused. - README's "Registry Explorer" bullet updated to reflect the live read. Also includes: - AUDIT_REPORT.md: full audit of the submission against the six bounty criteria, with 23 findings, an opportunities matrix, and a prioritized action plan. The "Must fix before submission" list drives the remaining work; `useResumeUnshield`, `matchZamaError`, error boundary, CI, and dead code stripping are all open. Vercel deploy and Mainnet relayer API key are marked as deferred (user-handled). Verified locally: - `tsc --noEmit` passes - `next build` succeeds, all 7 routes prerender - No new eslint errors introduced; pre-existing `any` / setState-in-effect warnings are tracked separately by Findings #3 and #16. --- AUDIT_REPORT.md | 229 +++++++++++++++++++++++++++++++++++++ README.md | 2 +- src/app/faucet/page.tsx | 17 ++- src/app/page.tsx | 142 +++++++++++++++++------ src/app/portfolio/page.tsx | 10 +- src/app/wrap/page.tsx | 16 ++- src/config/contracts.ts | 31 ++++- src/lib/registry-abi.ts | 62 ---------- src/lib/registry.ts | 214 ++++++++++++++++++++++++++++++++++ 9 files changed, 613 insertions(+), 110 deletions(-) create mode 100644 AUDIT_REPORT.md delete mode 100644 src/lib/registry-abi.ts create mode 100644 src/lib/registry.ts diff --git a/AUDIT_REPORT.md b/AUDIT_REPORT.md new file mode 100644 index 0000000..6b20040 --- /dev/null +++ b/AUDIT_REPORT.md @@ -0,0 +1,229 @@ +# ZamaVault — Bounty Submission Audit Report + +**Audit date:** 2026-06-21 +**Submission deadline:** 2026-07-07 AOE +**Target:** Zama Developer Program Mainnet Season 3 — Bounty Track +**Repository:** https://github.com/hosein-ul/zamavault +**Audited commit:** local `main` HEAD as of 2026-06-21 + +--- + +## 1. Executive summary + +ZamaVault is a visually polished Next.js front-end for the Zama confidential wrapper flows (shield/unshield/decrypt) plus a Sepolia mint faucet. However, **the application does not actually read the on-chain Wrappers Registry**: every page renders pairs from a hardcoded list in [contracts.ts](src/config/contracts.ts), and the registry ABI in [registry-abi.ts](src/lib/registry-abi.ts) is dead code. This is the single biggest gap versus the bounty brief, which explicitly asks the app to "surface every registered ERC-20 ↔ ERC-7984 wrapper pair from Zama's on-chain Wrappers Registry." It also directly undermines two of the six judging criteria — *coverage* and *extensibility* — because any new wrapper added to the registry tomorrow will never appear without a redeploy. + +Other meaningful gaps: no `useResumeUnshield` (a user who closes their tab between `unwrap` and `finalizeUnwrap` has no recovery path), no `matchZamaError` classification (every failure surfaces as a raw `err.message`), no relayer-API-key plumbing for Mainnet (Mainnet decrypt/shield/unshield will silently fail — *deferred, user-handled*), no live deployed URL (*deferred, user-handled*), no tests, no CI, no `.env.example`, no error boundaries, no pagination, no detection of revoked (`isValid == false`) registry entries, and no separation between reusable SDK-layer logic and the Next.js app (the bounty's stated category goal is "templates and resources for the developer ecosystem" — a flat single-app structure does not deliver that). + +What is solid: the decimals scaling fix described in [memory.md](memory.md) is correctly applied across the wrap, portfolio, and faucet flows; batched `useConfidentialBalances` on the Portfolio page is the right pattern; the wrap page is correctly gated behind an explicit "Decrypt to view" click rather than auto-prompting a permit on token select; RPC fallback transports are configured; and the visual design is genuinely strong. + +The path to a competitive submission is clear: replace the hardcoded list with a registry-backed hook (top priority); add `useResumeUnshield`, `matchZamaError`, an error boundary, and CI; and (time permitting) extract the registry/wrap/unwrap logic into a reusable `packages/` module. Mainnet relayer key and Vercel deploy are out of scope for this implementation pass — the user will handle them separately before submission. + +--- + +## 2. Findings table + +| # | Criterion | Finding | Severity | File(s) | Recommended fix | +|---|-----------|---------|----------|---------|-----------------| +| 1 | Coverage / Extensibility | Registry is never read on-chain; all pairs come from hardcoded `KNOWN_WRAPPERS`. `REGISTRY_ABI` and `REGISTRY_ADDRESSES` are dead code. | **Critical** | [src/config/contracts.ts](src/config/contracts.ts), [src/lib/registry-abi.ts](src/lib/registry-abi.ts), [src/app/page.tsx:26](src/app/page.tsx:26), [src/app/wrap/page.tsx:58](src/app/wrap/page.tsx:58), [src/app/portfolio/page.tsx:155](src/app/portfolio/page.tsx:155), [src/app/faucet/page.tsx:59](src/app/faucet/page.tsx:59) | Replace `KNOWN_WRAPPERS[chainId]` lookups with the SDK's `useListPairs` / `useTokenPairsRegistry` hook (or a `useReadContract` against `listPairs` + `getTokenConfidentialTokenPairsLength` + slice). Keep hardcoded metadata only as a *display-only* enrichment layer (logos, friendly names) keyed by address. | +| 2 | Correctness / UX | No `useResumeUnshield` implementation. A user closing their tab between the on-chain `unwrap` request and the `finalizeUnwrap` step has no recovery path; their wrapped balance is stuck pending. | **High** | [src/app/wrap/page.tsx:178-203](src/app/wrap/page.tsx:178) (only) | Add a "Pending unshield" banner on Portfolio and Wrap pages that calls `useResumeUnshield` to detect outstanding requests on mount, with a "Resume" action that completes finalization. | +| 3 | Correctness | All SDK errors are reduced to `err.message` strings; no `matchZamaError` classification. Signature-rejected, tx-reverted, allowance-too-low, relayer-down, ratelimit, and bad-chain all surface identically to the user. | **High** | [src/app/wrap/page.tsx:204-213](src/app/wrap/page.tsx:204), [src/app/faucet/page.tsx:129-137](src/app/faucet/page.tsx:129), [src/app/portfolio/page.tsx:219-232](src/app/portfolio/page.tsx:219) | Wrap every SDK call site in `matchZamaError(err, { signatureRejected: ..., relayerUnavailable: ..., decryptionFailed: ..., ... })` and produce a distinct toast title + recovery hint per case. | +| 4 | Production-readiness | No Relayer API key is plumbed into `RelayerWeb` for Mainnet. Mainnet shield / unshield / decrypt will fail with an unhelpful relayer-auth error and no fallback. ***Deferred — user-handled (key obtained later).*** | **High** | [src/providers/Providers.tsx:43-55](src/providers/Providers.tsx:43) | (a) Add `NEXT_PUBLIC_RELAYER_API_KEY` support **only** for build-time configuration and document the backend-proxy pattern per [Zama auth guide](https://docs.zama.org/protocol/sdk/guides/authentication.md); (b) when no key is configured, detect Mainnet selection and degrade to read-only mode with an explanatory banner ("Mainnet write operations require a Zama Relayer API key — browsing pairs only"). Do **not** ship a real key in `NEXT_PUBLIC_*`. | +| 5 | Production-readiness | No live deployed URL in [README.md](README.md), [package.json](package.json), or anywhere else. No `vercel.json`. Judges must `git clone && npm install` to evaluate. ***Deferred — user will deploy separately.*** | **High** | [README.md](README.md), [package.json](package.json) | Deploy to Vercel before submission; add the URL to the README headline and to a `homepage` field in `package.json`. | +| 6 | Coverage | Revoked registry entries (`isValid == false` but non-zero wrapper) are not detected anywhere. They would render as normal usable pairs and a user clicking "Shield" would hit a revert. | **Medium** | [src/config/contracts.ts](src/config/contracts.ts), [src/app/page.tsx](src/app/page.tsx) | When migrating to dynamic registry reads, expose `isValid` from the pair tuple, hide invalid pairs by default with a "Show revoked" toggle, and visually mark them with a "Revoked" badge. | +| 7 | Extensibility | Mainnet wrapper addresses are hardcoded with a stale comment ("Update as needed or read dynamically"). No mechanism to refresh. They may already drift from the [official mainnet addresses page](https://docs.zama.org/protocol/protocol-apps/addresses/mainnet.md). | **Medium** | [src/config/contracts.ts:86-143](src/config/contracts.ts:86) | Same fix as #1 — dynamic registry reads make this self-healing. As an interim mitigation, add a CI check (or a one-off script) that diffs the hardcoded list against the on-chain registry. | +| 8 | Coverage / UX | No pagination. Renders all pairs in one unpaginated table. A registry of 50+ pairs will produce a wall of rows; mobile becomes unusable. | **Medium** | [src/app/page.tsx:119-233](src/app/page.tsx:119) | Add page-size + `useMemo`-based slice, or virtualize with `@tanstack/react-virtual`. | +| 9 | Correctness / Extensibility | `REGISTRY_ABI` in [src/lib/registry-abi.ts](src/lib/registry-abi.ts) declares `getAllWrappers` / `getWrapperCount` / `getWrapper` / `getUnderlying` / `isRegistered` — these names **do not match** Zama's documented registry surface (`listPairs`, `getTokenConfidentialTokenPairsLength`, `isValid`, etc.). The ABI is wrong *and* unused. | **Medium** | [src/lib/registry-abi.ts](src/lib/registry-abi.ts) | Delete this file and use the SDK hooks (`useListPairs` / `useTokenPairsRegistry`) instead. If raw ABI is still needed (e.g. CLI/indexer), regenerate it from the official `WrappersRegistry` ABI. | +| 10 | UX | Mainnet vs Sepolia selector is duplicated in the header and on the home page (two independent `network-switcher` widgets). Visual inconsistency, and the in-page one bypasses wallet chain switching. | **Medium** | [src/components/layout/Header.tsx:173-186](src/components/layout/Header.tsx:173), [src/app/page.tsx:102-116](src/app/page.tsx:102) | Keep one network switcher (the header's, which correctly calls `switchChain` when connected). Remove or pure-display the in-page one. | +| 11 | UX | Portfolio uses batched `useConfidentialBalances` (good), but Wrap page uses single `useConfidentialBalance` per token selection. Selecting four tokens in succession on Wrap can prompt four separate permits. | **Medium** | [src/app/wrap/page.tsx:80-88](src/app/wrap/page.tsx:80) | Hoist permit issuance to a shared cache (already via `indexedDBStorage`); ensure the SDK reuses the session permit across token selections without re-prompting. Verify against `useRevokeSession` reset flow. | +| 12 | UX | "Awaiting Permit..." string is shown for both *signing in progress* and *fetch in progress*. A user who never clicked "Decrypt to view" sees nothing — but a user who clicked and then rejected sees the same "Awaiting Permit..." stuck indefinitely with no recovery button. | **Medium** | [src/app/wrap/page.tsx:261-263](src/app/wrap/page.tsx:261) | Surface the `decryptWrapperError` (already destructured at line 84 but never rendered) with a retry button. | +| 13 | UX / Accessibility | Only one `aria-*` attribute in the entire codebase ([TokenIcon.tsx](src/components/ui/TokenIcon.tsx)). Icon-only buttons (close, copy, theme toggle, swap-arrow) lack labels. Modal lacks `role="dialog"` + `aria-modal`. Color contrast in some themes (Frost) likely fails WCAG AA on `text-muted` over glassmorphism. | **Medium** | [src/components/ui/Modal.tsx](src/components/ui/Modal.tsx), [src/components/ui/CopyButton.tsx](src/components/ui/CopyButton.tsx), [src/components/layout/Header.tsx](src/components/layout/Header.tsx) | Add `aria-label` to all icon-only buttons; add `role="dialog" aria-modal="true" aria-labelledby` to Modal; run an axe-core or Lighthouse pass and fix critical issues. | +| 14 | UX | No stale-while-revalidate / persisted cache for registry & balances. A slow RPC produces a blank screen. The QueryClient's `staleTime: 30_000` does not survive a refresh because there is no persistence layer. | **Medium** | [src/providers/Providers.tsx:58-65](src/providers/Providers.tsx:58) | Add `@tanstack/react-query-persist-client` with `localStorage` persistence for the registry-listing query. | +| 15 | Correctness | The faucet's `COOLDOWN_SECONDS = 5` is a UI-only timer that resets on refresh. The comment in [README.md:15](README.md) calls it a feature but it is not enforced on-chain. | **Low** | [src/app/faucet/page.tsx:42](src/app/faucet/page.tsx:42), [README.md:15](README.md) | Either remove the cooldown (and the README claim) or persist `nextEligibleAt` in `localStorage` so the timer survives a refresh. Be explicit in copy that it is a client-side limiter. | +| 16 | Code quality | TS strict mode is **enabled** ([tsconfig.json:7](tsconfig.json:7)) but three critical paths still use `err: any`. | **Low** | [src/app/faucet/page.tsx:129](src/app/faucet/page.tsx:129), [src/app/wrap/page.tsx:204](src/app/wrap/page.tsx:204), [src/app/portfolio/page.tsx:269](src/app/portfolio/page.tsx:269) | Type as `unknown` and narrow with `matchZamaError` (fix #3). | +| 17 | Code quality | No test suite, no `.github/workflows`, no CI. | **Medium** | (none) | Add a GitHub Actions workflow that runs `eslint`, `tsc --noEmit`, and `next build` on PR. Add at minimum a Vitest test for [utils.ts](src/lib/utils.ts) `formatAmount` / `parseAmount` (the decimals math is load-bearing per [memory.md](memory.md) and is exactly the kind of regression a test catches). | +| 18 | Code quality / Extensibility | Single flat Next.js app. No separation between reusable logic and the UI. The bounty track's category goal is "templates and resources for the developer ecosystem"; a flat repo signals the opposite. | **High** *(differentiation)* | (whole repo) | Convert to a thin monorepo: `packages/registry-sdk` (pure-TS module exporting `listPairs(client, chainId)`, `shield`, `unshield`, `decryptBalance` — viem-based, no React) and `apps/web` (Next.js app, depends on the package). The package then doubles as a publishable artifact and a CLI substrate. | +| 19 | Production-readiness | No `.env.example`. The README documents `NEXT_PUBLIC_SEPOLIA_RPC` / `NEXT_PUBLIC_MAINNET_RPC` / `NEXT_PUBLIC_WALLETCONNECT_PROJECT_ID` but a new developer must read source to discover the third one. | **Low** | [README.md:74-79](README.md:74), [src/providers/Providers.tsx:12](src/providers/Providers.tsx:12) | Add `.env.example` at repo root with all three keys (empty values) and document each. | +| 20 | Production-readiness | No error boundary. An unexpected error in any page component will white-screen the whole app. | **Medium** | [src/app/layout.tsx](src/app/layout.tsx), [src/app/ClientLayout.tsx](src/app/ClientLayout.tsx) | Add a top-level `error.tsx` (Next.js App Router error boundary) with a "Reload" action and the underlying error message in a `
`. | +| 21 | Code quality | `import { sepolia } from 'wagmi/chains'` in [wrap/page.tsx:21](src/app/wrap/page.tsx:21) is unused. Several `style={{...}}` blocks duplicate values that already exist in `globals.css`. | **Low** | [src/app/wrap/page.tsx:21](src/app/wrap/page.tsx:21) | Remove unused imports; run `eslint --fix`. | +| 22 | Coverage | The README claims "discover all verified ERC-20 ↔ ERC-7984 wrapper pairs on Ethereum and Sepolia" — currently false (no discovery, no verification). | **High** | [README.md:14](README.md:14), [src/app/page.tsx:54-56](src/app/page.tsx:54) | Either fix the registry coverage (preferred) or correct the copy until it is fixed. Misrepresenting capability to judges is worse than under-promising. | +| 23 | Differentiation | No activity / history view, no operator approvals UI, no extracted package, no indexer, no Hoodi support, no CLI. Competing teams are almost certain to ship at least one of these. | **Medium** *(differentiation)* | (none) | See section 4 (Opportunities) for ranking. | + +--- + +## 3. Detailed findings by criterion + +### 3.1 Coverage + +**3.1.1 Registry is not read on-chain (Finding #1, Critical).** +`KNOWN_WRAPPERS` is the *sole* source of pair data for every page: +- Registry table at [src/app/page.tsx:26](src/app/page.tsx:26): `const wrappers = KNOWN_WRAPPERS[activeChainId] ?? [];` +- Wrap page at [src/app/wrap/page.tsx:58](src/app/wrap/page.tsx:58): same. +- Portfolio at [src/app/portfolio/page.tsx:155](src/app/portfolio/page.tsx:155): same. +- Faucet at [src/app/faucet/page.tsx:59](src/app/faucet/page.tsx:59): same (hardcoded to Sepolia only). + +A grep across `src/` for `REGISTRY_ABI`, `REGISTRY_ADDRESSES`, `listPairs`, `useListPairs`, `useTokenPairsRegistry`, `useWrapperDiscovery`, `getAllWrappers`, `getWrapperCount` returns **zero call sites**. The ABI file and the registry address constant exist purely as decoration. This is the single most impactful change the project needs: the bounty's coverage criterion is defined by registry-completeness, and the registry is not being consulted. + +**Recommended fix.** Replace the hardcoded source with one of: +- `useListPairs({ chainId })` from `@zama-fhe/react-sdk` (preferred — handles pagination and caching), +- or `useReadContract` against the real registry ABI (`getTokenConfidentialTokenPairsLength` + a sliced `listPairs(start, count)` call). + +Keep `TOKEN_INFO` in [src/config/tokens.ts](src/config/tokens.ts) as a display-only enrichment layer keyed by symbol or underlying address. + +**3.1.2 No revoked-pair detection (Finding #6, Medium).** When a pair has `isValid == false` but the wrapper address is still non-zero, the UI will treat it as a healthy pair and Shield will revert. Surface `isValid` and visually mark revoked entries. + +**3.1.3 No pagination (Finding #8, Medium).** The table renders all rows. Acceptable today (7 pairs), structurally broken at 50+. + +**3.1.4 Wrong ABI surface (Finding #9, Medium).** [registry-abi.ts](src/lib/registry-abi.ts) declares `getAllWrappers`, `getWrapperCount`, `getWrapper`, `getUnderlying`, `isRegistered` — none of which match the documented `WrappersRegistry` surface (`listPairs`, `getTokenConfidentialTokenPairsLength`, `isValid`, `getPairFromConfidentialToken`, etc.). Either the file is from a prototype or hallucinated. Delete it. + +### 3.2 Correctness + +**3.2.1 No `useResumeUnshield` (Finding #2, High).** The unshield flow involves two on-chain interactions plus an off-chain decryption hop. A user who closes the tab after `unwrap` but before `finalizeUnwrap` has no UI affordance to recover. Implementing `useResumeUnshield` on Portfolio (and showing a "1 pending unshield" banner) is a small change with disproportionate UX impact and a direct match to the docs' "Activity Feeds" and "useResumeUnshield" references. + +**3.2.2 No `matchZamaError` (Finding #3, High).** All three SDK call sites collapse every failure into a single toast: +- [wrap/page.tsx:204-213](src/app/wrap/page.tsx:204): `err.message || 'The transaction was rejected or failed.'` +- [faucet/page.tsx:129-137](src/app/faucet/page.tsx:129): `err.message || 'The faucet mint transaction was rejected.'` +- [portfolio/page.tsx:222-228](src/app/portfolio/page.tsx:222): `err.message || 'The permit signature request was rejected or failed.'` + +Note: with the dynamic registry migration (Finding #1) eliminating one of the three faucet call sites is not in scope — the faucet keeps its own write path against the underlying mock ERC-20, which can still revert (insufficient ETH for gas, paused contract, etc.); `matchZamaError` is still the right wrapper there even though it is not a relayer call. + +Concrete scenarios that produce *no distinct* feedback today: +- User rejects MetaMask signature → identical to "tx reverted". +- Relayer rate-limited → identical to "network error". +- Wrapper not registered for the connected chain → identical to "tx reverted". +- Encrypted balance is zero / address never held the token → no error, just a `0n` value indistinguishable from "decrypt succeeded with zero". + +Wrap each call site in `matchZamaError(err, { signatureRejected, relayerUnavailable, decryptionFailed, allowanceTooLow, ... })`. + +**3.2.4 Decimals scaling.** The fix described in [memory.md](memory.md) is applied correctly in the code I read: +- Wrap input parses with `underlyingDecimals` ([wrap/page.tsx:121](src/app/wrap/page.tsx:121)). +- Unwrap input parses with `wrapperDecimals` (same line). +- Portfolio formats with `wrapper.wrapperDecimals` ([portfolio/page.tsx:85](src/app/portfolio/page.tsx:85)). +- Public-vs-confidential balances in the wrap panel use the right decimals on each side ([wrap/page.tsx:253-260](src/app/wrap/page.tsx:253)). + +Faucet parses with `selectedWrapper.decimals` (underlying) at [faucet/page.tsx:112-113](src/app/faucet/page.tsx:112) — also correct. + +**3.2.5 Permit auto-fire.** The Wrap page passes `enabled: !!address && !!selectedWrapper?.erc7984Address` to `useConfidentialBalance` ([wrap/page.tsx:87](src/app/wrap/page.tsx:87)), which would normally fire as soon as a token is selected. In practice the UI gates display behind a "Decrypt to view" button ([wrap/page.tsx:264-281](src/app/wrap/page.tsx:264)) that calls `refetch()`. This works *only because* the SDK does not pre-issue a permit on the initial enabled fetch — it returns `undefined` until refetch. This is a fragile contract; if the SDK behavior changes, every token-select will trigger a wallet prompt. Consider switching to `enabled: hasUserClickedDecrypt` to make the gating explicit. + +### 3.3 Extensibility + +**3.3.1 Hardcoded wrapper list (Finding #1 again).** Already covered above — this is *the* extensibility failure. + +**3.3.2 Hardcoded Mainnet addresses (Finding #7, Medium).** The Mainnet block in [contracts.ts:86-143](src/config/contracts.ts:86) has the same problem with extra blast radius: Mainnet pair additions cannot reach the app without a redeploy, and a wrong address there silently routes user funds to the wrong contract. I did not full-text-cross-check every Mainnet address against the official page in this session — the well-known underlyings (USDC, USDT, WETH) are correct, but the seven hardcoded ERC-7984 wrapper addresses **must** be verified against [docs.zama.org/protocol/protocol-apps/addresses/mainnet.md](https://docs.zama.org/protocol/protocol-apps/addresses/mainnet.md) before submission. Better still, eliminate them via dynamic reads (#1). + +**3.3.3 No logic / UI separation (Finding #18, High for differentiation).** Every wrapper-related operation is implemented inside a Next.js page component. There is no `lib/registry.ts` exporting `listPairs(client, chainId)`, no `lib/shield.ts` exporting a viem-based `shield(client, account, pair, amount)`, no CLI, no published package. The bounty's category goal is "templates and resources for the developer ecosystem" — a competing team that ships even a thin `@zamavault/sdk` npm package will out-position this submission on the extensibility axis. + +**3.3.4 Chain configuration.** This is one of the better parts: [src/config/chains.ts](src/config/chains.ts) centralizes Sepolia + Mainnet config, and `SupportedChainId` is reused across files. Adding Hoodi is a 10-line change here — see Opportunities. + +### 3.4 UX + +**3.4.1 Permit signing surprise.** The wrap page is correctly gated behind "Decrypt to view" (good). The portfolio page is correctly gated behind "Decrypt Balance" / "Decrypt All" (good). No silent permit prompts on page load — confirmed by inspection. + +**3.4.2 Failure states.** As noted in #12 and #3, the wrap page destructures `decryptWrapperError` ([wrap/page.tsx:84](src/app/wrap/page.tsx:84)) but never renders it. A user who rejects a permit gets stuck on "Awaiting Permit..." with no retry path. + +**3.4.3 "Balance 0" vs "Balance not decrypted."** Handled adequately: portfolio shows `••••••` + "Encrypted" badge when not decrypted, and `0 cXXX` when decrypted-and-zero. Wrap page shows the literal value (`0`) once decrypted, which is correct. + +**3.4.4 Revoked / invalid pairs.** No handling — see #6. + +**3.4.5 Duplicate network switchers.** See #10 — the home page's switcher does not call `switchChain` and so silently desyncs from the wallet's actual chain. + +**3.4.6 Accessibility.** Only one `aria-*` attribute in the entire `src/` tree. Modal lacks `role="dialog" aria-modal aria-labelledby`. Theme variants (Frost especially) need a contrast pass. The custom ` setShowRevoked(e.target.checked)} + /> + Show revoked + + )} +

All other Mainnet wrappers (USDC, USDT, WETH, BRON, ZAMA, tGBP, XAUt) wrap well-known, publicly-traded tokens. + +2. **Underlying address is a vanity address.** The underlying token address `0xbeeffABcd0dB09589Dd21854aa760C52aB4bf04F` begins with `beeff` followed by `ABcd` — a clear vanity-generation pattern. While not inherently wrong, this is atypical for production token deployments and is commonly associated with test contracts. + +3. **Possible relationship to `tGBP`.** The name "bbqTGBP" contains "TGBP" as a suffix, raising the possibility that this is a variant, fork, or test deployment related to the existing `ctGBP` wrapper (`0xa873...eDD9`). If so, having both in the production registry without any disambiguation could confuse users and developers building on the registry. + +### What we did in ZamaVault + +- ZamaVault reads the `WrappersRegistry` **live on-chain** via `useListPairs({ metadata: true })` from `@zama-fhe/react-sdk`. This means any pair registered on-chain appears automatically in our app. +- We added a **manual blocklist** specifically for `cbbqTGBP` (`0xBA4cFF6ED6F7Cb2A58776dECa4E984b498446762`) to exclude it from the user-facing display.

We handle both correctly in ZamaVault: +- The mock `ctGBPMock` appears in both the registry table and the faucet (mintable). +- The restricted `ctGBP` appears in the registry table but is **excluded from the faucet** (since its underlying does not have a public `mint`). +- Both appear in the Portfolio for balance decryption. + +We mention this only because the dual-entry pattern might confuse other bounty participants — a brief note in the Sepolia address docs clarifying "the mock wrapper is for development, the non-mock wrapper wraps the real testnet asset" would be helpful. + +--- + +## Summary + +| Entry | Network | Status | Our Action | +|---|---|---|---| +| `cbbqTGBP` (`0xBA4c...6762`) | Mainnet | Suspected test/placeholder | Blocklisted in ZamaVault display | +| Dual `ctGBP` / `ctGBPMock` | Sepolia | Intentional (mock + real) | Both displayed correctly, faucet filters mock-only | + +We appreciate any clarification the Zama team can provide.

+ +
+

+ + Decimal Scaling +

+

+ All wrapper tokens use 6 decimals regardless of the + underlying token's precision (which may be 18). This is because FHE + operates on euint64 — a 64-bit integer that would overflow + at large 18-decimal values. The wrapper contract automatically scales + amounts during shield and unshield. +

+ +
+ + + + The unshield is a two-phase process: the unwrap + request goes on-chain, then the Zama Gateway processes it and triggers + finalization. This typically takes 30–60 seconds. + + The Zama Gateway needs to decrypt the encrypted amount to verify + you have sufficient balance, then sends a finalization transaction. + If you close the browser during this window, use the{' '} + "Resume Unshield" banner to complete it later. + + } + /> + + } + /> + +

+ If you close your browser between the unwrap request and finalization, + don't worry — ZamaVault detects pending unshields automatically and + shows a yellow "Resume Unshield" banner. Click + "Resume" to complete the process. Your tokens are never lost. +

+ +

+ Fully Homomorphic Encryption (FHE) is a cryptographic scheme that + allows arbitrary computations on encrypted data without decrypting it first. Zama's + fhEVM is a modified Ethereum Virtual Machine that supports FHE + operations natively in Solidity smart contracts. +

+

+ ERC-7984 is the confidential token standard built on fhEVM. Instead + of storing balances as public uint256, wrapper contracts store them as + euint64 — encrypted 64-bit integers. The plaintext is never visible on-chain; + only the token owner can decrypt it. +

+
+ Key properties of ERC-7984 tokens: +
    +
  • Balances are on-chain ciphertexts — unreadable by validators, indexers, or block explorers
    • +
  • Transfer amounts are encrypted — confidential even from recipients until decrypted
    • +
  • Decryption requires the owner's EIP-712 permit (see below)
    • +
  • Underlying ERC-20 is always 1:1 collateralized in the wrapper contract
    • +
+
+ +
+ + {/* ════════════════════════════════════════════════════════════════ */} +
+

+ This is the most common source of bugs when integrating Zama FHE tokens. + Read carefully. +

+

+ FHE operates on euint64 — a 64-bit unsigned integer + with a maximum value of ~1.84 × 10¹⁹. A standard 18-decimal ERC-20 token + represents 1.0 ETH as 10¹⁸. Multiplied by any meaningful token amount, this + would overflow the 64-bit limit quickly. +

+

+ Therefore, all ERC-7984 wrapper tokens use 6 decimals, regardless + of the underlying token's precision. The wrapper contract scales amounts + automatically during shielding and unshielding. +

+ +
+ ⚠️ Critical rule: When calling useShield, parse the + amount using the underlying token's decimals. When calling{' '} + useUnshield, always use 6 decimals (wrapper decimals). +
+ +

Decision table

+ + + + + + + + + + + + + + + + + + + + + + + + + +
OperationDecimals to useExample (1.0 WETH)
Shield (wrap)parseUnits(amount, underlyingDecimals)parseUnits("1", 18) → 10¹⁸
Unshield (unwrap)parseUnits(amount, 6)parseUnits("1", 6) → 10⁶
Display confidential balanceformatUnits(balance, 6)formatUnits(1_000_000n, 6) → "1.0"
+ + +
+ + {/* ════════════════════════════════════════════════════════════════ */} +
+

+ Reading a confidential balance requires an EIP-712 typed-data signature from the + token owner's wallet. This signature authorizes the Zama Gateway to decrypt the + ciphertext and return the plaintext value to the frontend session. +

+ +
+ 🚨 Security rule — NEVER auto-fire permits. Every call to{' '} + useConfidentialBalance or useConfidentialBalances with{' '} + enabled: true will immediately request a wallet signature. Always gate it + behind an explicit decryptRequested boolean state that is only set{' '} + true on user click. +
+ +

+
+ {[ + { n: '1', t: 'User clicks "Decrypt"', d: 'Set decryptRequested = true in your component state.' }, + { n: '2', t: 'SDK requests EIP-712 signature', d: 'The hook constructs a typed data payload and asks MetaMask/Rabby to sign it.

Only your account\'s ciphertexts can be decrypted with your key.' }, + { n: '5', t: 'Plaintext returned to browser', d: 'The decrypted bigint balance is returned to your component. It is never stored on-chain in plaintext.' }, + ].map((s) => ( +
+
{s.n}

+ {s.t} +

{s.d}

+
+
+ ))} +
+ +
+ Token selector reset: When the user changes the selected token in + your UI, reset decryptRequested synchronously in the{' '} + onChange handler — not only in a useEffect. A one-frame + delay in the effect can cause the old true value to combine with the + new token address and auto-fire a permit. +
+ + { + setSelectedToken(newToken); + setDecryptRequested(false); // ← must happen in same handler, not useEffect +}; + +const { data: balance } = useConfidentialBalance({ + tokenAddress: selectedToken.erc7984Address, + enabled: decryptRequested && !!address, // ← explicit gate +});`} + /> +

This is the canonical source of truth. -Confidential balances are stored on-chain as `euint64` ciphertext handles. To display the plaintext to the user, ZamaVault uses Zama's `useConfidentialBalance` hook, gated behind an **explicit user click** — the EIP-712 permit signature must never auto-fire on render. The flow: +Registry contracts: +- Sepolia: `0x2f0750Bbb0A246059d80e94c454586a7F27a128e` +- Mainnet: `0xeb5015fF021DB115aCe010f23F55C2591059bBA0` -1. User clicks **Decrypt** next to any encrypted balance. -2. Wallet shows a typed-data signature request (EIP-712, not a transaction — zero gas). -3. The signature scopes an ephemeral session key to that wallet + contract. -4. SDK sends ciphertext + permit to the Zama Gateway/Coprocessor. -5. Coprocessor verifies the signature, decrypts, returns plaintext to the browser. -6. The plaintext is rendered client-side; private keys never leave the wallet and plaintext is never stored on-chain. +All pairs (including revoked ones with `isValid: false`) are shown. Revoked pairs display a "Revoked" badge and have disabled wrap/unwrap actions. -### Shield (wrap) — one or two transactions +### Layer 2 — Local snapshot fallback (`src/config/contracts.ts`) -`WrappedToken.shield(amount)` routes through one of two paths depending on the underlying ERC-20: +When the wallet is disconnected or the on-chain fetch is loading, the app falls back to `KNOWN_WRAPPERS`, a hardcoded snapshot. A "Cached" banner alerts users that the list may be incomplete. This allows unconnected visitors to browse. -| Path | Triggered when | Wallet prompts | Tokens (mainnet) | -| ------------------- | --------------------------------------------- | -------------- | -------------------- | -| `transferAndCall` | Underlying implements **ERC-1363** | 1 | cTGBP, cZAMA | -| `approve` + `wrap` | Underlying does **not** implement ERC-1363 | 2 | cUSDC, cUSDT, cWETH, cBRON | +### Layer 3 — Local config (`src/config/custom-pairs.ts`) -The SDK detects ERC-1363 support automatically via `supportsInterface` — callers don't choose a path. On the two-tx path, ZamaVault checks the existing ERC-20 allowance and passes `approvalStrategy: 'skip'` when it's already sufficient, so users aren't prompted for a fresh `approve(0)` + `approve(amount)` every time. +Custom or dev-only pairs can be declared in `src/config/custom-pairs.ts` without touching the on-chain registry or any other file.

This is because FHE operates on `euint64` (a 64-bit unsigned integer), which would overflow at 18-decimal values. The wrapper contract scales amounts during shield and unshield. `formatAmount`/`parseAmount` in `src/lib/utils.ts` must be kept in sync with this constraint — see the inline comments. +**Step 1.** Open `src/config/custom-pairs.ts` ---- +**Step 2.** Add an entry to the `CUSTOM_PAIRS` array: + +```ts +import type { CustomPair } from '@/config/contracts'; + +export const CUSTOM_PAIRS: CustomPair[] = [ + { + erc20Address: '0xYourERC20TokenAddress', // underlying ERC-20 + erc7984Address: '0xYourERC7984WrapperAddress', // confidential wrapper + symbol: 'MYT', + name: 'My Test Token', + decimals: 18, // underlying ERC-20 decimals + wrapperDecimals: 6, // almost always 6 for ERC-7984 wrappers + source: 'custom', + note: 'Dev token deployed 2025-06-27 — awaiting on-chain registration', + }, +]; +``` + +**Step 3.** Run `npm run dev` — the pair appears immediately in: +- Registry table `/app` — with a "Custom" badge +- Wrap/Unwrap selector `/app/wrap` — in the token dropdown +- Portfolio `/app/portfolio` — as a decryptable position +- Faucet `/app/faucet` — if the ERC-20 has a public `mint()` function + +**Step 4.** Commit `custom-pairs.ts` to persist the pair across deployments. -## Tech stack - -| Layer | Library / version | -| ----------------- | ---------------------------------------------------------------------------------------------------------------- | -| Framework | [Next.js 16](https://nextjs.org/) (App Router, Turbopack, static prerender) | -| UI runtime | [React 19](https://react.dev/) | -| Web3 | [Wagmi 3](https://wagmi.sh/) + [Viem 2](https://viem.sh/) | -| FHE | [`@zama-fhe/react-sdk` 3](https://docs.zama.org/protocol/sdk/overview) | -| Data fetching | [TanStack Query 5](https://tanstack.com/query) | -| Animation | [motion (Framer Motion) 12](https://motion.dev/) for landing primitives | -| 3D / canvas | [three.js](https://threejs.org/) + [@react-three/fiber](https://r3f.docs.pmnd.rs/) | -| Landing styling | [Tailwind v4](https://tailwindcss.com/) (scoped to `/`) | -| App styling | Vanilla CSS custom properties (scoped to `/app/*`) | -| Icons | [lucide-react](https://lucide.dev/) + [react-icons](https://react-icons.github.io/react-icons/) | -| Magic UI | [magicui.design](https://magicui.design/) — TextAnimate, MagicCard, BorderBeam, NumberTicker, Marquee, BlurFade | -| Confetti | [canvas-confetti](https://www.npmjs.com/package/canvas-confetti) | -| Language | TypeScript 5 (strict mode) | +> ⚠️ ZamaVault cannot verify that `erc7984Address` is a legitimate ERC-7984 implementation.

About ZamaVault -| Network | Chain ID | Status | -|---|---|---| -| Ethereum Sepolia | 11155111 | ✅ Primary — all features | -| Ethereum Mainnet | 1 | ✅ Registry browsing | +Traditional blockchain networks expose all transaction values and account balances to public block explorers, posing significant security and privacy risks for both retail users and commercial enterprises. ZamaVault addresses this challenge by utilizing Torus Fully Homomorphic Encryption (TFHE) on-chain via Zama's FHEVM. -All bounty features (shield, unshield, decrypt, faucet) are live on **Sepolia**. +It wraps public ERC-20 tokens into **ERC-7984 Confidential Wrappers** (cTokens), converting open balance data into cryptographic ciphertext handles (`euint64`). Transactions and balances are processed on-chain in their encrypted state, ensuring confidentiality while maintaining decentralized validation. --- -## Features +## 2.

Core Features Deep Dive + +ZamaVault is divided into specialized modules tailored for retail and enterprise confidentiality management: + +### 3.1 Registry Browser (`/app`) +Displays a live list of registered public-to-confidential token pairs fetched directly from the on-chain registry contract. +* **On-Chain Sync:** Syncs contract metadata, validation states, and pair registry entries in real-time. +* **Revocation Status:** Automatically marks revoked token pairs as inactive, disabling wrapping actions and providing alerts. +* **Custom Indicators:** Visually distinguishes local configuration pairs from official on-chain pairs. + +### 3.2 Shielding & Unshielding Engine (`/app/wrap`) +Facilitates the conversion between public assets (ERC-20) and confidential assets (ERC-7984 cTokens). +* **WASM FHE Encryption:** Automatically encrypts the inputs locally in the browser before submitting the transaction to the network. +* **Multi-Step Status Tracking:** Provides real-time visual progress across transaction states: Approval, Shielding, and On-Chain Confirmation. +* **Smart Route Optimization:** Dynamically switches between the 1-transaction path (using ERC-1363 `transferAndCall`) and the 2-transaction path (using standard `approve` + `shield`) based on the target token's features. + +### 3.3 Portfolio Manager & Decrypter (`/app/portfolio`) +A dashboard displaying all user balance details. Balances remain securely locked and hidden by default. +* **Batch Decryption:** Leverages EIP-712 permits to batch-decrypt all registry balances simultaneously, reducing user interaction overhead. +* **Arbitrary Token Scanner:** Allows developers to input any ERC-7984 contract address. ZamaVault scans the address, queries metadata, and adds it to the user's dashboard. +* **My Recent Activity:** A personal ledger displaying historical transactions (shields, unwraps, faucet claims) made by the active wallet. + +### 3.4 DeFi Analytics Dashboard (`/app/analytics`) +Provides protocol-wide analytics and transaction metrics. +* **Total Value Shielded (TVS):** Displays live protocol statistics on wrapped assets, calculations, and pool metrics. +* **Global Activity Stream:** Displays a live-updating transaction history of all wrapping events occurring across the registry. + +### 3.5 Token Faucet (`/app/faucet`) +An integrated faucet allowing developers to claim testnet mock tokens to experiment with FHE capabilities. +* **Single-Click Minting:** Requests public tokens (`USDT`, `USDC`, `WETH`, `BRON`) and automatically initiates shielding. +* **Interactive Guides:** Linked directly to the onboarding tutorials. + +### 3.6 Onboarding Center (`/app/learn`) +An interactive, step-by-step onboarding tutorial designed to guide users through the FHE lifecycle: +1. **Wallet Connection:** Connecting to Ethereum Sepolia. +2. **Faucet Claims:** Minting mock testnet tokens. +3. **Asset Shielding:** Converting public tokens to cTokens. +4. **Balance Decryption:** Executing EIP-712 signature prompts. +5. **Asset Unshielding:** Restoring public balances. + +### 3.7 Developer Tools & ABI Explorer (`/app/developers`) +A developer sandbox containing technical resources for custom integrations: +* **Interactive ABI Explorer:** Read and query functions of ERC-20 and ERC-7984 contracts directly. +* **SDK Integration Code Generator:** Explains hooks like `useShield`, `useUnshield`, and `useConfidentialBalance` with copy-pasteable React snippets. + +### 3.8 Docs Hub (`/app/docs`) +An in-app documentation portal explaining technical architecture, decimal scaling rules, and EIP-712 permit verification processes. -### Layer 1 — On-chain WrappersRegistry (primary, canonical) - -When a wallet is connected on the matching chain, the app reads the official Zama WrappersRegistry live via `@zama-fhe/react-sdk`'s `useListPairs` hook. This is the canonical source of truth. - -Registry contracts: -- Sepolia: `0x2f0750Bbb0A246059d80e94c454586a7F27a128e` -- Mainnet: `0xeb5015fF021DB115aCe010f23F55C2591059bBA0` - -All pairs (including revoked ones with `isValid: false`) are shown. Revoked pairs display a "Revoked" badge and have disabled wrap/unwrap actions. +--- -### Layer 2 — Local snapshot fallback (`src/config/contracts.ts`) +## 4. Technical Architecture & Data Flows -When the wallet is disconnected or the on-chain fetch is loading, the app falls back to `KNOWN_WRAPPERS`, a hardcoded snapshot. A "Cached" banner alerts users that the list may be incomplete. This allows unconnected visitors to browse. +ZamaVault's architecture decouples public blockchain logic, local cryptographic calculations, and decentralized key management: -### Layer 3 — Local config (`src/config/custom-pairs.ts`) +``` +┌────────────────────────────────────────────────────────┐ +│ Browser UI (Next.js / React) │ +└──────────────────────────┬─────────────────────────────┘ + │ + ┌────────────────────┴────────────────────┐ + ▼ ▼ +┌───────────┐ ┌───────────┐ +│ Wagmi & │ │ Zama React│ +│ Viem │ │ SDK │ +└─────┬─────┘ └─────┬─────┘ + │ │ (WASM FHEVM library) + │ ▼ + │ ┌─────────────┐ + │ │ Local WASM │ + │ │ Cryptography│ + │ └──────┬──────┘ + │ │ + ▼ ▼ +┌───────────────────────────────────────────────────────┐ +│ Ethereum Sepolia / FHEVM │ +│ ┌────────────────────────┐ ┌──────────────────────┐ │ +│ │ WrappersRegistry │ │ cToken Wrapper │ │ +│ └────────────────────────┘ └──────────────────────┘ │ +└───────────────────────────────────┬───────────────────┘ + │ + ▼ + ┌──────────────────────┐ + │ Zama KMS / GW │ + └──────────────────────┘ +``` -Custom or dev-only pairs can be declared in `src/config/custom-pairs.ts` without touching the on-chain registry or any other file. These appear with a "Custom" badge so users can distinguish them from official pairs. +### 4.1 FHE Shielding Flow (Public to Confidential) + +The diagram below illustrates the process of shielding public ERC-20 tokens into encrypted cTokens: + +```mermaid +sequenceDiagram + autonumber + actor User as Browser Wallet + participant SDK as Zama SDK (WASM) + participant E20 as ERC-20 Contract + participant Wrap as cToken Wrapper (ERC-7984) + participant Coproc as Zama Coprocessor (FHE) + + User->>SDK: Enter Amount to Shield (e.g., 100 USDT) + Note over SDK: Encrypts amount locally into FHE ciphertext + SDK->>E20: Approve cToken contract to transfer 100 USDT + E20-->>User: Tx Confirmed + SDK->>Wrap: Call shield(encryptedAmount) + Note over Wrap: Transfers underlying USDT to vault + Wrap->>Coproc: Request state updates for encrypted balances + Note over Coproc: Off-chain FHE execution on encrypted integers + Coproc-->>Wrap: Verify results & publish updated euint64 handles + Wrap-->>User: Tx Confirmed (Shield Completed) +``` -**De-duplication rule**: if a custom pair's ERC-20 address later appears in the on-chain registry, the registry version wins and the custom entry is silently dropped. +### 4.2 FHE Decryption Flow (Confidential to Plaintext) + +To query and view confidential balances, ZamaVault uses EIP-712 permits. The process prevents gas consumption and ensures the plaintext is only visible to the user: + +```mermaid +sequenceDiagram + autonumber + actor User as User Wallet (MetaMask) + participant SDK as Zama SDK (WASM) + participant KMS as Zama KMS & Gateway + participant Node as Blockchain State + + User->>SDK: Click Decrypt Balance + Note over SDK: Generates EIP-712 Permit Typed Data + SDK->>User: Request Signature (Permit authorization) + User-->>SDK: Signed EIP-712 Signature + SDK->>KMS: Send Permit + Signature + Ciphertext Handle + KMS->>Node: Verify permission & signature on-chain + Node-->>KMS: Verified (True) + Note over KMS: Re-encrypts network FHE ciphertext to session transport key + KMS-->>SDK: Return Re-encrypted Ciphertext + Note over SDK: Decrypts locally in-browser using session key + SDK->>User: Display Plaintext Balance (e.g., 1,000 cUSDT) +``` --- -## How to Add a New ERC-20 ↔ ERC-7984 Pair +## 5. Security & Cryptographic Trust Model -### Option A — Local Config (immediate, no on-chain action required) +ZamaVault's privacy architecture relies on the following security properties: -Best for: dev-only pairs, staging tokens, or pairs awaiting official registration. +* **Lattice-Based Cryptography:** FHE is built on Ring Learning With Errors (LWE) lattice assumptions, which are mathematically recognized as secure against quantum computer attacks. +* **Session Key Decryption:** Plaintext values are never transmitted across the network or stored on servers. Decryption occurs strictly inside the local browser context using ephemeral session keys. +* **EIP-712 Permit Scoping:** Permit signatures are read-only and restricted to balance views. They cannot approve token transfers, withdraw funds, or modify contract states. +* **Zero-Knowledge KMS Boundaries:** The Key Management System (KMS) re-encrypts FHE ciphertexts from the network key to the user's session key. This cryptographic handshake ensures that neither the KMS gateway nor any relayer can inspect the user's plaintext values. -**Step 1.** Open `src/config/custom-pairs.ts` +--- -**Step 2.** Add an entry to the `CUSTOM_PAIRS` array: +## 6. Hybrid Registry Sourcing Strategy -```ts -import type { CustomPair } from '@/config/contracts'; +To guarantee uptime and developer flexibility, ZamaVault merges token information from three layers: -export const CUSTOM_PAIRS: CustomPair[] = [ - { - erc20Address: '0xYourERC20TokenAddress', // underlying ERC-20 - erc7984Address: '0xYourERC7984WrapperAddress', // confidential wrapper - symbol: 'MYT', - name: 'My Test Token', - decimals: 18, // underlying ERC-20 decimals - wrapperDecimals: 6, // almost always 6 for ERC-7984 wrappers - source: 'custom', - note: 'Dev token deployed 2025-06-27 — awaiting on-chain registration', - }, -]; +``` +┌────────────────────────────────────────────────────────┐ +│ ZamaVault Client │ +├────────────────────────────────────────────────────────┤ +│ 1.

The wrapper must implement ERC-165 with interface ID `0x4958f2a4`. Only add addresses you deployed and control. +1. **Layer 1: On-Chain WrappersRegistry (Canonical Source)** + Reads official token pairs directly from the Zama WrappersRegistry contract on Ethereum Sepolia or Mainnet. This is the canonical source of truth. +2. **Layer 2: Local Snapshot Fallback (`src/config/contracts.ts`)** + If the user's wallet is disconnected or the RPC connection fails, ZamaVault falls back to a local JSON snapshot of known wrappers. This allows visitors to browse the catalog offline. +3. **Layer 3: Local Custom Configuration (`src/config/custom-pairs.ts`)** + Allows developers to add custom token wrappers (e.g., local development pairs or tokens awaiting official registration) by adding them to a local configuration file. + * **De-duplication Logic:** If a custom token pair is subsequently registered on-chain, ZamaVault automatically prioritizes the canonical on-chain record and drops the local duplicate. --- -### Option B — Official On-chain Registration +## 7. B2B & Enterprise Use Cases -Once a pair is registered in the official Zama WrappersRegistry, ZamaVault surfaces it automatically for all users — no code change needed. +Confidential ERC-7984 wrapper standard implementations enable several corporate use cases: -**Prerequisites:** -- An ERC-7984 confidential wrapper that: - - Implements ERC-165 and returns `true` for interface ID `0x4958f2a4` - - Wraps a specific ERC-20 underlying token -- Authorization from the Zama Protocol DAO governance (registry owner) - -**Registration call** (Solidity): -```solidity -// Sepolia registry: 0x2f0750Bbb0A246059d80e94c454586a7F27a128e -registry.registerConfidentialToken( - address erc20TokenAddress, - address confidentialWrapperAddress -); -``` - -Validation performed on-chain: -- Neither address can be zero -- Confidential token must implement ERC-165 with interface `0x4958f2a4` -- ERC-20 must not already have an associated wrapper -- Wrapper must not already be associated with another ERC-20 - -See [Zama Registry docs](https://docs.zama.org/protocol/protocol-apps/confidential-tokens/wrapper-registry) for full details. +* **Confidential Corporate Payroll:** Allows companies to pay salaries, consulting fees, and bonuses in stablecoins (e.g., cUSDC) on public ledgers without exposing employee compensation details or monthly payroll figures. +* **OTC Trading & Institutional Dark Pools:** Enables institutions to execute block trades and OTC swaps privately. Keeping trade sizes and token balances encrypted during settlement prevents front-running and visible order books. +* **Private Treasury Reserves:** Allows corporations to manage reserve assets, yield farming positions, and inter-company financing on-chain without exposing strategic financial positioning to competitors. --- -### Option C — Decrypt an Arbitrary ERC-7984 Address (no registration needed) +## 8. How to Configure a New Token Pair -To decrypt the balance of any ERC-7984 token not in the registry: +Developers can register custom wrappers immediately without submitting on-chain governance proposals. -1. Go to `/app/portfolio` -2. Scroll to **"Decrypt Any ERC-7984 Token"** -3. Paste the contract address — ZamaVault auto-fetches the token symbol from the contract -4.

Local Development & Setup -- **Value-privacy, not anonymity**: sender and recipient addresses are public on-chain. Only amounts and balances are encrypted. -- **TFHE on-chain**: balances are stored as `euint64` ciphertexts — arithmetic can be performed without decrypting. -- **EIP-712 permits are read-only**: the permit signature cannot transfer tokens or approve contracts. Default TTL: 30 days, cached in `localStorage`. -- **Non-custodial**: ZamaVault never holds funds. All operations go directly to on-chain contracts. -- **KMS guarantee**: the Zama KMS re-encrypts ciphertexts under your session transport key via a cryptographic protocol — it cannot learn your plaintext balance. +### Prerequisites +* **Node.js:** v18.17.0 or higher +* **Package Manager:** npm / yarn ---- - -## Local Development +### Installation ```bash -# Install +# Clone the repository +git clone https://github.com/hosein-ul/zamavault.git +cd zamavault + +# Install dependencies npm install +``` -# Dev server -npm run dev # → http://localhost:3000 +### Running the Application -# Type check +```bash +# Run the Next.js Turbopack development server +npm run dev +``` +Open `http://localhost:3000` to interact with the application. + +### Compilation & Build Verification + +```bash +# Run TypeScript compilation checks npx tsc --noEmit -# Production build +# Compile production bundle npm run build ``` -No environment variables required for local development.

Only `refetchPublicBalance()` and `refetchAllowance()` are allowed. - -### 6.2 Zero Display Bug for 18-Decimal Tokens -**Cause:** `formatAmount(balance, 18)` on 6-decimal FHE balance → value close to zero. -**Solution:** Always use `formatAmount(balance, 6)` for FHE confidential balances. - -### 6.3 Race Condition Bug for Token Select -**Cause:** `setDecryptRequested(false)` only in `useEffect` → one-frame delay → old `true` request triggered with new token address. -**Solution:** Perform the reset **synchronously** in the `onChange` handler. - -### 6.4 How Tooltips Should Be Handled -**Cause:** Tooltip wrapped the entire button → click on Tooltip did not work. -**Solution:** Always place `` without children (defaults to a ? icon) **after** the button/badge. - -### 6.5 TVL Ranking Bug -**Cause:** Sorting on raw bigint — ZAMA with 18 decimals had a larger raw value than USDC with 6 decimals. -**Solution:** Calculate `tvlHuman` (normalized float) and use it for sorting and progress bar widths. - -### 6.6 CZAMA Instead of cZAMA -**Cause:** `.badge { text-transform: uppercase }` in CSS. -**Solution:** Removed `text-transform` from `.badge`.

Executive summary - -ShadowLine is a visually polished Next.js front-end for the Zama confidential wrapper flows (shield/unshield/decrypt) plus a Sepolia mint faucet. However, **the application does not actually read the on-chain Wrappers Registry**: every page renders pairs from a hardcoded list in [contracts.ts](src/config/contracts.ts), and the registry ABI in [registry-abi.ts](src/lib/registry-abi.ts) is dead code. This is the single biggest gap versus the bounty brief, which explicitly asks the app to "surface every registered ERC-20 ↔ ERC-7984 wrapper pair from Zama's on-chain Wrappers Registry." It also directly undermines two of the six judging criteria — *coverage* and *extensibility* — because any new wrapper added to the registry tomorrow will never appear without a redeploy. - -Other meaningful gaps: no `useResumeUnshield` (a user who closes their tab between `unwrap` and `finalizeUnwrap` has no recovery path), no `matchZamaError` classification (every failure surfaces as a raw `err.message`), no relayer-API-key plumbing for Mainnet (Mainnet decrypt/shield/unshield will silently fail — *deferred, user-handled*), no live deployed URL (*deferred, user-handled*), no tests, no CI, no `.env.example`, no error boundaries, no pagination, no detection of revoked (`isValid == false`) registry entries, and no separation between reusable SDK-layer logic and the Next.js app (the bounty's stated category goal is "templates and resources for the developer ecosystem" — a flat single-app structure does not deliver that). - -What is solid: the decimals scaling fix described in [memory.md](memory.md) is correctly applied across the wrap, portfolio, and faucet flows; batched `useConfidentialBalances` on the Portfolio page is the right pattern; the wrap page is correctly gated behind an explicit "Decrypt to view" click rather than auto-prompting a permit on token select; RPC fallback transports are configured; and the visual design is genuinely strong. - -The path to a competitive submission is clear: replace the hardcoded list with a registry-backed hook (top priority); add `useResumeUnshield`, `matchZamaError`, an error boundary, and CI; and (time permitting) extract the registry/wrap/unwrap logic into a reusable `packages/` module. Mainnet relayer key and Vercel deploy are out of scope for this implementation pass — the user will handle them separately before submission. - ---- - -## 2. Findings table - -| # | Criterion | Finding | Severity | File(s) | Recommended fix | -|---|-----------|---------|----------|---------|-----------------| -| 1 | Coverage / Extensibility | Registry is never read on-chain; all pairs come from hardcoded `KNOWN_WRAPPERS`. `REGISTRY_ABI` and `REGISTRY_ADDRESSES` are dead code. | **Critical** | [src/config/contracts.ts](src/config/contracts.ts), [src/lib/registry-abi.ts](src/lib/registry-abi.ts), [src/app/page.tsx:26](src/app/page.tsx:26), [src/app/wrap/page.tsx:58](src/app/wrap/page.tsx:58), [src/app/portfolio/page.tsx:155](src/app/portfolio/page.tsx:155), [src/app/faucet/page.tsx:59](src/app/faucet/page.tsx:59) | Replace `KNOWN_WRAPPERS[chainId]` lookups with the SDK's `useListPairs` / `useTokenPairsRegistry` hook (or a `useReadContract` against `listPairs` + `getTokenConfidentialTokenPairsLength` + slice). Keep hardcoded metadata only as a *display-only* enrichment layer (logos, friendly names) keyed by address. | -| 2 | Correctness / UX | No `useResumeUnshield` implementation. A user closing their tab between the on-chain `unwrap` request and the `finalizeUnwrap` step has no recovery path; their wrapped balance is stuck pending. | **High** | [src/app/wrap/page.tsx:178-203](src/app/wrap/page.tsx:178) (only) | Add a "Pending unshield" banner on Portfolio and Wrap pages that calls `useResumeUnshield` to detect outstanding requests on mount, with a "Resume" action that completes finalization. | -| 3 | Correctness | All SDK errors are reduced to `err.message` strings; no `matchZamaError` classification. Signature-rejected, tx-reverted, allowance-too-low, relayer-down, ratelimit, and bad-chain all surface identically to the user. | **High** | [src/app/wrap/page.tsx:204-213](src/app/wrap/page.tsx:204), [src/app/faucet/page.tsx:129-137](src/app/faucet/page.tsx:129), [src/app/portfolio/page.tsx:219-232](src/app/portfolio/page.tsx:219) | Wrap every SDK call site in `matchZamaError(err, { signatureRejected: ..., relayerUnavailable: ..., decryptionFailed: ..., ... })` and produce a distinct toast title + recovery hint per case. | -| 4 | Production-readiness | No Relayer API key is plumbed into `RelayerWeb` for Mainnet. Mainnet shield / unshield / decrypt will fail with an unhelpful relayer-auth error and no fallback. ***Deferred — user-handled (key obtained later).*** | **High** | [src/providers/Providers.tsx:43-55](src/providers/Providers.tsx:43) | (a) Add `NEXT_PUBLIC_RELAYER_API_KEY` support **only** for build-time configuration and document the backend-proxy pattern per [Zama auth guide](https://docs.zama.org/protocol/sdk/guides/authentication.md); (b) when no key is configured, detect Mainnet selection and degrade to read-only mode with an explanatory banner ("Mainnet write operations require a Zama Relayer API key — browsing pairs only"). Do **not** ship a real key in `NEXT_PUBLIC_*`. | -| 5 | Production-readiness | No live deployed URL in [README.md](README.md), [package.json](package.json), or anywhere else. No `vercel.json`. Judges must `git clone && npm install` to evaluate. ***Deferred — user will deploy separately.*** | **High** | [README.md](README.md), [package.json](package.json) | Deploy to Vercel before submission; add the URL to the README headline and to a `homepage` field in `package.json`. | -| 6 | Coverage | Revoked registry entries (`isValid == false` but non-zero wrapper) are not detected anywhere. They would render as normal usable pairs and a user clicking "Shield" would hit a revert. | **Medium** | [src/config/contracts.ts](src/config/contracts.ts), [src/app/page.tsx](src/app/page.tsx) | When migrating to dynamic registry reads, expose `isValid` from the pair tuple, hide invalid pairs by default with a "Show revoked" toggle, and visually mark them with a "Revoked" badge. | -| 7 | Extensibility | Mainnet wrapper addresses are hardcoded with a stale comment ("Update as needed or read dynamically"). No mechanism to refresh. They may already drift from the [official mainnet addresses page](https://docs.zama.org/protocol/protocol-apps/addresses/mainnet.md). | **Medium** | [src/config/contracts.ts:86-143](src/config/contracts.ts:86) | Same fix as #1 — dynamic registry reads make this self-healing. As an interim mitigation, add a CI check (or a one-off script) that diffs the hardcoded list against the on-chain registry. | -| 8 | Coverage / UX | No pagination. Renders all pairs in one unpaginated table. A registry of 50+ pairs will produce a wall of rows; mobile becomes unusable. | **Medium** | [src/app/page.tsx:119-233](src/app/page.tsx:119) | Add page-size + `useMemo`-based slice, or virtualize with `@tanstack/react-virtual`. | -| 9 | Correctness / Extensibility | `REGISTRY_ABI` in [src/lib/registry-abi.ts](src/lib/registry-abi.ts) declares `getAllWrappers` / `getWrapperCount` / `getWrapper` / `getUnderlying` / `isRegistered` — these names **do not match** Zama's documented registry surface (`listPairs`, `getTokenConfidentialTokenPairsLength`, `isValid`, etc.). The ABI is wrong *and* unused. | **Medium** | [src/lib/registry-abi.ts](src/lib/registry-abi.ts) | Delete this file and use the SDK hooks (`useListPairs` / `useTokenPairsRegistry`) instead. If raw ABI is still needed (e.g. CLI/indexer), regenerate it from the official `WrappersRegistry` ABI. | -| 10 | UX | Mainnet vs Sepolia selector is duplicated in the header and on the home page (two independent `network-switcher` widgets). Visual inconsistency, and the in-page one bypasses wallet chain switching. | **Medium** | [src/components/layout/Header.tsx:173-186](src/components/layout/Header.tsx:173), [src/app/page.tsx:102-116](src/app/page.tsx:102) | Keep one network switcher (the header's, which correctly calls `switchChain` when connected). Remove or pure-display the in-page one. | -| 11 | UX | Portfolio uses batched `useConfidentialBalances` (good), but Wrap page uses single `useConfidentialBalance` per token selection. Selecting four tokens in succession on Wrap can prompt four separate permits. | **Medium** | [src/app/wrap/page.tsx:80-88](src/app/wrap/page.tsx:80) | Hoist permit issuance to a shared cache (already via `indexedDBStorage`); ensure the SDK reuses the session permit across token selections without re-prompting. Verify against `useRevokeSession` reset flow. | -| 12 | UX | "Awaiting Permit..." string is shown for both *signing in progress* and *fetch in progress*. A user who never clicked "Decrypt to view" sees nothing — but a user who clicked and then rejected sees the same "Awaiting Permit..." stuck indefinitely with no recovery button. | **Medium** | [src/app/wrap/page.tsx:261-263](src/app/wrap/page.tsx:261) | Surface the `decryptWrapperError` (already destructured at line 84 but never rendered) with a retry button. | -| 13 | UX / Accessibility | Only one `aria-*` attribute in the entire codebase ([TokenIcon.tsx](src/components/ui/TokenIcon.tsx)). Icon-only buttons (close, copy, theme toggle, swap-arrow) lack labels. Modal lacks `role="dialog"` + `aria-modal`. Color contrast in some themes (Frost) likely fails WCAG AA on `text-muted` over glassmorphism. | **Medium** | [src/components/ui/Modal.tsx](src/components/ui/Modal.tsx), [src/components/ui/CopyButton.tsx](src/components/ui/CopyButton.tsx), [src/components/layout/Header.tsx](src/components/layout/Header.tsx) | Add `aria-label` to all icon-only buttons; add `role="dialog" aria-modal="true" aria-labelledby` to Modal; run an axe-core or Lighthouse pass and fix critical issues. | -| 14 | UX | No stale-while-revalidate / persisted cache for registry & balances. A slow RPC produces a blank screen. The QueryClient's `staleTime: 30_000` does not survive a refresh because there is no persistence layer. | **Medium** | [src/providers/Providers.tsx:58-65](src/providers/Providers.tsx:58) | Add `@tanstack/react-query-persist-client` with `localStorage` persistence for the registry-listing query. | -| 15 | Correctness | The faucet's `COOLDOWN_SECONDS = 5` is a UI-only timer that resets on refresh. The comment in [README.md:15](README.md) calls it a feature but it is not enforced on-chain. | **Low** | [src/app/faucet/page.tsx:42](src/app/faucet/page.tsx:42), [README.md:15](README.md) | Either remove the cooldown (and the README claim) or persist `nextEligibleAt` in `localStorage` so the timer survives a refresh. Be explicit in copy that it is a client-side limiter. | -| 16 | Code quality | TS strict mode is **enabled** ([tsconfig.json:7](tsconfig.json:7)) but three critical paths still use `err: any`. | **Low** | [src/app/faucet/page.tsx:129](src/app/faucet/page.tsx:129), [src/app/wrap/page.tsx:204](src/app/wrap/page.tsx:204), [src/app/portfolio/page.tsx:269](src/app/portfolio/page.tsx:269) | Type as `unknown` and narrow with `matchZamaError` (fix #3). | -| 17 | Code quality | No test suite, no `.github/workflows`, no CI. | **Medium** | (none) | Add a GitHub Actions workflow that runs `eslint`, `tsc --noEmit`, and `next build` on PR. Add at minimum a Vitest test for [utils.ts](src/lib/utils.ts) `formatAmount` / `parseAmount` (the decimals math is load-bearing per [memory.md](memory.md) and is exactly the kind of regression a test catches). | -| 18 | Code quality / Extensibility | Single flat Next.js app. No separation between reusable logic and the UI. The bounty track's category goal is "templates and resources for the developer ecosystem"; a flat repo signals the opposite. | **High** *(differentiation)* | (whole repo) | Convert to a thin monorepo: `packages/registry-sdk` (pure-TS module exporting `listPairs(client, chainId)`, `shield`, `unshield`, `decryptBalance` — viem-based, no React) and `apps/web` (Next.js app, depends on the package). The package then doubles as a publishable artifact and a CLI substrate. | -| 19 | Production-readiness | No `.env.example`. The README documents `NEXT_PUBLIC_SEPOLIA_RPC` / `NEXT_PUBLIC_MAINNET_RPC` / `NEXT_PUBLIC_WALLETCONNECT_PROJECT_ID` but a new developer must read source to discover the third one. | **Low** | [README.md:74-79](README.md:74), [src/providers/Providers.tsx:12](src/providers/Providers.tsx:12) | Add `.env.example` at repo root with all three keys (empty values) and document each. | -| 20 | Production-readiness | No error boundary. An unexpected error in any page component will white-screen the whole app. | **Medium** | [src/app/layout.tsx](src/app/layout.tsx), [src/app/ClientLayout.tsx](src/app/ClientLayout.tsx) | Add a top-level `error.tsx` (Next.js App Router error boundary) with a "Reload" action and the underlying error message in a `
`. | -| 21 | Code quality | `import { sepolia } from 'wagmi/chains'` in [wrap/page.tsx:21](src/app/wrap/page.tsx:21) is unused. Several `style={{...}}` blocks duplicate values that already exist in `globals.css`. | **Low** | [src/app/wrap/page.tsx:21](src/app/wrap/page.tsx:21) | Remove unused imports; run `eslint --fix`. | -| 22 | Coverage | The README claims "discover all verified ERC-20 ↔ ERC-7984 wrapper pairs on Ethereum and Sepolia" — currently false (no discovery, no verification). | **High** | [README.md:14](README.md:14), [src/app/page.tsx:54-56](src/app/page.tsx:54) | Either fix the registry coverage (preferred) or correct the copy until it is fixed. Misrepresenting capability to judges is worse than under-promising. | -| 23 | Differentiation | No activity / history view, no operator approvals UI, no extracted package, no indexer, no Hoodi support, no CLI. Competing teams are almost certain to ship at least one of these. | **Medium** *(differentiation)* | (none) | See section 4 (Opportunities) for ranking. | - ---- - -## 3. Detailed findings by criterion - -### 3.1 Coverage - -**3.1.1 Registry is not read on-chain (Finding #1, Critical).** -`KNOWN_WRAPPERS` is the *sole* source of pair data for every page: -- Registry table at [src/app/page.tsx:26](src/app/page.tsx:26): `const wrappers = KNOWN_WRAPPERS[activeChainId] ?? [];` -- Wrap page at [src/app/wrap/page.tsx:58](src/app/wrap/page.tsx:58): same. -- Portfolio at [src/app/portfolio/page.tsx:155](src/app/portfolio/page.tsx:155): same. -- Faucet at [src/app/faucet/page.tsx:59](src/app/faucet/page.tsx:59): same (hardcoded to Sepolia only). - -A grep across `src/` for `REGISTRY_ABI`, `REGISTRY_ADDRESSES`, `listPairs`, `useListPairs`, `useTokenPairsRegistry`, `useWrapperDiscovery`, `getAllWrappers`, `getWrapperCount` returns **zero call sites**. The ABI file and the registry address constant exist purely as decoration. This is the single most impactful change the project needs: the bounty's coverage criterion is defined by registry-completeness, and the registry is not being consulted. - -**Recommended fix.** Replace the hardcoded source with one of: -- `useListPairs({ chainId })` from `@zama-fhe/react-sdk` (preferred — handles pagination and caching), -- or `useReadContract` against the real registry ABI (`getTokenConfidentialTokenPairsLength` + a sliced `listPairs(start, count)` call). - -Keep `TOKEN_INFO` in [src/config/tokens.ts](src/config/tokens.ts) as a display-only enrichment layer keyed by symbol or underlying address. - -**3.1.2 No revoked-pair detection (Finding #6, Medium).** When a pair has `isValid == false` but the wrapper address is still non-zero, the UI will treat it as a healthy pair and Shield will revert. Surface `isValid` and visually mark revoked entries. - -**3.1.3 No pagination (Finding #8, Medium).** The table renders all rows. Acceptable today (7 pairs), structurally broken at 50+. - -**3.1.4 Wrong ABI surface (Finding #9, Medium).** [registry-abi.ts](src/lib/registry-abi.ts) declares `getAllWrappers`, `getWrapperCount`, `getWrapper`, `getUnderlying`, `isRegistered` — none of which match the documented `WrappersRegistry` surface (`listPairs`, `getTokenConfidentialTokenPairsLength`, `isValid`, `getPairFromConfidentialToken`, etc.). Either the file is from a prototype or hallucinated. Delete it. - -### 3.2 Correctness - -**3.2.1 No `useResumeUnshield` (Finding #2, High).** The unshield flow involves two on-chain interactions plus an off-chain decryption hop. A user who closes the tab after `unwrap` but before `finalizeUnwrap` has no UI affordance to recover. Implementing `useResumeUnshield` on Portfolio (and showing a "1 pending unshield" banner) is a small change with disproportionate UX impact and a direct match to the docs' "Activity Feeds" and "useResumeUnshield" references. - -**3.2.2 No `matchZamaError` (Finding #3, High).** All three SDK call sites collapse every failure into a single toast: -- [wrap/page.tsx:204-213](src/app/wrap/page.tsx:204): `err.message || 'The transaction was rejected or failed.'` -- [faucet/page.tsx:129-137](src/app/faucet/page.tsx:129): `err.message || 'The faucet mint transaction was rejected.'` -- [portfolio/page.tsx:222-228](src/app/portfolio/page.tsx:222): `err.message || 'The permit signature request was rejected or failed.'` - -Note: with the dynamic registry migration (Finding #1) eliminating one of the three faucet call sites is not in scope — the faucet keeps its own write path against the underlying mock ERC-20, which can still revert (insufficient ETH for gas, paused contract, etc.); `matchZamaError` is still the right wrapper there even though it is not a relayer call. - -Concrete scenarios that produce *no distinct* feedback today: -- User rejects MetaMask signature → identical to "tx reverted". -- Relayer rate-limited → identical to "network error". -- Wrapper not registered for the connected chain → identical to "tx reverted". -- Encrypted balance is zero / address never held the token → no error, just a `0n` value indistinguishable from "decrypt succeeded with zero". - -Wrap each call site in `matchZamaError(err, { signatureRejected, relayerUnavailable, decryptionFailed, allowanceTooLow, ... })`. - -**3.2.4 Decimals scaling.** The fix described in [memory.md](memory.md) is applied correctly in the code I read: -- Wrap input parses with `underlyingDecimals` ([wrap/page.tsx:121](src/app/wrap/page.tsx:121)). -- Unwrap input parses with `wrapperDecimals` (same line). -- Portfolio formats with `wrapper.wrapperDecimals` ([portfolio/page.tsx:85](src/app/portfolio/page.tsx:85)). -- Public-vs-confidential balances in the wrap panel use the right decimals on each side ([wrap/page.tsx:253-260](src/app/wrap/page.tsx:253)). - -Faucet parses with `selectedWrapper.decimals` (underlying) at [faucet/page.tsx:112-113](src/app/faucet/page.tsx:112) — also correct. - -**3.2.5 Permit auto-fire.** The Wrap page passes `enabled: !!address && !!selectedWrapper?.erc7984Address` to `useConfidentialBalance` ([wrap/page.tsx:87](src/app/wrap/page.tsx:87)), which would normally fire as soon as a token is selected. In practice the UI gates display behind a "Decrypt to view" button ([wrap/page.tsx:264-281](src/app/wrap/page.tsx:264)) that calls `refetch()`. This works *only because* the SDK does not pre-issue a permit on the initial enabled fetch — it returns `undefined` until refetch. This is a fragile contract; if the SDK behavior changes, every token-select will trigger a wallet prompt. Consider switching to `enabled: hasUserClickedDecrypt` to make the gating explicit. - -### 3.3 Extensibility - -**3.3.1 Hardcoded wrapper list (Finding #1 again).** Already covered above — this is *the* extensibility failure. - -**3.3.2 Hardcoded Mainnet addresses (Finding #7, Medium).** The Mainnet block in [contracts.ts:86-143](src/config/contracts.ts:86) has the same problem with extra blast radius: Mainnet pair additions cannot reach the app without a redeploy, and a wrong address there silently routes user funds to the wrong contract. I did not full-text-cross-check every Mainnet address against the official page in this session — the well-known underlyings (USDC, USDT, WETH) are correct, but the seven hardcoded ERC-7984 wrapper addresses **must** be verified against [docs.zama.org/protocol/protocol-apps/addresses/mainnet.md](https://docs.zama.org/protocol/protocol-apps/addresses/mainnet.md) before submission. Better still, eliminate them via dynamic reads (#1). - -**3.3.3 No logic / UI separation (Finding #18, High for differentiation).** Every wrapper-related operation is implemented inside a Next.js page component. There is no `lib/registry.ts` exporting `listPairs(client, chainId)`, no `lib/shield.ts` exporting a viem-based `shield(client, account, pair, amount)`, no CLI, no published package. The bounty's category goal is "templates and resources for the developer ecosystem" — a competing team that ships even a thin `@shadowline/sdk` npm package will out-position this submission on the extensibility axis. - -**3.3.4 Chain configuration.** This is one of the better parts: [src/config/chains.ts](src/config/chains.ts) centralizes Sepolia + Mainnet config, and `SupportedChainId` is reused across files. Adding Hoodi is a 10-line change here — see Opportunities. - -### 3.4 UX - -**3.4.1 Permit signing surprise.** The wrap page is correctly gated behind "Decrypt to view" (good). The portfolio page is correctly gated behind "Decrypt Balance" / "Decrypt All" (good). No silent permit prompts on page load — confirmed by inspection. - -**3.4.2 Failure states.** As noted in #12 and #3, the wrap page destructures `decryptWrapperError` ([wrap/page.tsx:84](src/app/wrap/page.tsx:84)) but never renders it. A user who rejects a permit gets stuck on "Awaiting Permit..." with no retry path. - -**3.4.3 "Balance 0" vs "Balance not decrypted."** Handled adequately: portfolio shows `••••••` + "Encrypted" badge when not decrypted, and `0 cXXX` when decrypted-and-zero. Wrap page shows the literal value (`0`) once decrypted, which is correct. - -**3.4.4 Revoked / invalid pairs.** No handling — see #6. - -**3.4.5 Duplicate network switchers.** See #10 — the home page's switcher does not call `switchChain` and so silently desyncs from the wallet's actual chain. - -**3.4.6 Accessibility.** Only one `aria-*` attribute in the entire `src/` tree. Modal lacks `role="dialog" aria-modal aria-labelledby`. Theme variants (Frost especially) need a contrast pass. The custom ``'s `onChange` handler (not just in a `useEffect`). - 3. Removed `refetchWrapperBalance()` from the automatic balance-sync `useEffect` — only public balance and allowance auto-refresh. - 4. Created `ConfidentialBalanceInline` component with proper states: Decrypt button → Awaiting signature → Value → Retry on error. - -### Problem 8: Generic Error Messages for All Failures -* **Symptom:** Every SDK error (signature rejected, relayer down, tx reverted, insufficient balance) showed the same "Transaction Failed" toast with raw `err.message`. -* **Solution:** - 1. Created `src/lib/errors.ts` with `classifyError(err)` using `matchZamaError` from `@zama-fhe/sdk`. - 2. Maps 15+ Zama SDK error codes to distinct user-friendly `{ title, message, retryable }` objects. - 3. Fallback patterns catch common wallet rejections (MetaMask "user rejected", WalletConnect "ACTION_REJECTED", etc.). - 4. All three `catch (err: any)` sites replaced with `catch (err: unknown)` + `classifyError`. - -### Problem 9: No Recovery for Interrupted Unshield -* **Symptom:** A user closing their browser tab between the `unwrap` transaction and the `finalizeUnwrap` step had no way to resume — their tokens were stuck pending. -* **Solution:** - 1. Created `PendingUnshieldBanner` component using `loadPendingUnshield` (checks SDK storage on mount) and `useResumeUnshield` (completes finalization). - 2. Shows a yellow warning banner with "Resume" button when a pending unshield is detected. - 3. Integrated on both Portfolio page (per-wrapper) and Wrap page (for selected token). - ---- - -## 💡 Best Practices for Zama FHE Frontend Projects - -1. **Always Verify Decimals On-Chain:** Never assume a wrapper matches the underlying token's decimals. Write a quick read script (like `scratch_check.js`) to verify the wrapper's `decimals()` output. -2. **Batch Permits Where Possible:** Use batch hooks for decryption (`useConfidentialBalances`) to minimize wallet interaction prompts. -3. **Handle Case Insensitivity:** FHE Relayer/Gateway responses might return token address keys in lowercase or mixed case. Implement `.toLowerCase()` keys when lookup results are cached. -4. **Use Fallback Transports:** In Wagmi configs, always provide fallback providers to guarantee dapp stability. -5. **Never Auto-Fire Permits:** Gate every `useConfidentialBalance` behind an explicit `decryptRequested` state. Reset it synchronously on token change — not in `useEffect` (one-frame race condition). -6. **Use matchZamaError for Error Handling:** The Zama SDK exports typed error codes. Use `matchZamaError(err, { SIGNING_REJECTED: ..., ... })` instead of `err.message` for user-facing errors. -7. **Normalize Mock Symbols:** Sepolia mock tokens have on-chain symbols like `USDCMock`. Strip the `Mock` suffix at the registry-read boundary and show a separate "Mock" badge in the UI. -8. **Blocklist Suspicious Registry Entries:** The on-chain registry may contain test/placeholder entries (e.g., `cbbqTGBP` on Mainnet with vanity address `0xbeeff...`). Use a documented blocklist rather than hiding the issue. -9. **Read the Registry Dynamically:** Never hardcode wrapper pairs as the sole data source. Use `useListPairs` from the SDK or raw `listPairs` contract calls. Keep hardcoded pairs only as a disconnected-wallet fallback. - ---- - -## 📋 Remaining Plan (as of 2026-06-23) - -See `CLAUDE.md` for full project context.

Fully Homomorphic Encryption

+

+ Fully Homomorphic Encryption (FHE) is a cryptographic scheme that allows + arbitrary computation on encrypted data without decrypting it first.

+ +

The ERC-7984 standard

+

+ ERC-7984 is the confidential token standard built on the fhEVM. Instead of + storing balances as a public uint256, a wrapper contract stores them as{' '} + euint64 — an encrypted 64-bit integer. The plaintext is never on-chain; only the + token owner can decrypt it. +

+ + + + + + + Key properties of ERC-7984 tokens: +
    +
  • + Balances are on-chain ciphertexts — unreadable by validators, indexers, or block + explorers. +
    • +
  • Transfer amounts are encrypted — confidential even from recipients until decrypted.
    • +
  • Decryption requires the owner's EIP-712 permit.
    • +
  • The underlying ERC-20 is always 1:1 collateralized inside the wrapper contract.
    • +
+ + +

What FHE does and does not hide

+

+ FHE hides values — balances and transfer amounts. It does not hide the{' '} + graph: the fact that address A interacted with a given wrapper contract, and + when, is still public, because transactions and their senders are public on Ethereum.

Shield (wrap)

+

+ A shield is a two-transaction dance: an ERC-20 approve() so the wrapper can pull + your tokens, then wrap(), which locks the ERC-20 and mints you an encrypted{' '} + euint64 balance. ShadowLine runs the approval, waits for its receipt, refreshes + the allowance, then wraps — passing approvalStrategy: 'skip' so the SDK + doesn't try to approve again. +

+ + + + USDT-style tokens: some ERC-20s (real USDT, and this app's USDTMock + which replicates it) revert an approve() that changes a non-zero allowance + straight to another non-zero value. If an allowance is already outstanding, zero it first + (approve(spender, 0), await the receipt), then approve the real amount. Standard + tokens with a zero allowance are unaffected. + + +

Unshield (unwrap)

+

+ Unshielding is two phases. First an on-chain unwrap() request burns your + ciphertext and registers the intent. Then Zama's Gateway produces a decryption proof and + finalizes the unwrap — typically ~30–60 seconds later — releasing the underlying ERC-20 back + to your address. +

+
    +
  • Amounts for unshield always use 6 decimals (wrapper decimals).
    • +
  • + Because finalization is asynchronous, the pending unwrap tx hash is persisted so the + operation can be resumed if you close the tab. +
    • +
+ +

Resuming an interrupted unshield

+

+ The SDK does not auto-persist the pending unwrap. ShadowLine saves the unwrap tx hash the + moment it's submitted; on the next visit it reads it back with{' '} + loadPendingUnshield and offers a Resume action wired to{' '} + useResumeUnshield. See the SDK Hooks page for the + exact signatures. +

+ + + The activity feed on the Wrap page auto-refreshes a few seconds after a shield or unshield + confirms, so a fresh transaction appears without a manual reload. + + + ); +} diff --git a/src/app/app/docs/_docs/content/transfer.tsx b/src/app/app/docs/_docs/content/transfer.tsx new file mode 100644 index 0000000..09c8398 --- /dev/null +++ b/src/app/app/docs/_docs/content/transfer.tsx @@ -0,0 +1,74 @@ +'use client'; + +import React from 'react'; +import Link from 'next/link'; +import { Lead, P, H2, UL, CodeBlock, Callout } from '../components'; + +export default function Transfer() { + return ( + <> + + A confidential transfer moves ERC-7984 tokens where the amount is encrypted on-chain — hidden + from block explorers and even from the recipient until they decrypt it.

Using the SDK

Private payroll & compensation

+

+ Companies paying contributors on-chain today expose every salary to public scrutiny — anyone + can track an address and reconstruct the full comp structure. Wrapping payroll tokens into + confidential wrappers keeps amounts encrypted on-chain. The recipient holds the ciphertext; + only they can decrypt the value with an EIP-712 permit. Attestations (hire date, role) can + remain on-chain without leaking the number itself. +

+ +

Sealed-bid auctions

+

+ Traditional on-chain auctions require bids to be public, enabling sniping and last-second + manipulation. With ERC-7984 wrappers, each bid is an encrypted amount submitted to a smart + contract. The contract performs comparisons on ciphertext — no participant learns another + bid until the auctioneer chooses to finalize. ShadowLine's shield flow handles the + ERC-20 → confidential conversion that feeds into such contracts. +

+ +

DAO treasury & budget privacy

+

+ DAOs frequently need to approve grants or operational spending without surfacing exact + numbers to competitors or exploiters before execution. Confidential token flows let a + multi-sig hold and transfer budget allocations as encrypted balances. The DAO's + governance rules stay on-chain; the amounts move privately until finalization. +

+ +

Front-run resistant DeFi

+

+ Any large swap, liquidity provision, or liquidation on a public mempool is visible before + it lands. Wrapping the input amount keeps MEV bots blind to the size of the upcoming + trade. The ciphertext is only decrypted inside the EVM at execution time — by then the + block is already sealed. +

+ +

Private P2P payments

+

+ Sending money between wallets reveals the amount to every block explorer, data aggregator, + and anyone who knows either address. A confidential transfer (see{' '} + Confidential Transfer) submits an encrypted amount — + the recipient must run their own decrypt to learn what they received, and observers see + only that a transaction occurred. +

+ +

Vesting & lockup schedules

+

+ Token vesting contracts that hold large allocations are targets for social engineering and + market manipulation once balances are known. Wrapping vested amounts as confidential tokens + removes the live balance signal. The cliff and linear schedule logic stays on-chain; only + the holder can reveal what has vested so far. +

+ + + All of these patterns share one foundation: ERC-20 tokens are locked inside the ERC-7984 + wrapper (1:1 collateralized) and the encrypted handle is what moves on-chain. ShadowLine is + the interface that makes shielding, unshielding, and transferring those handles easy. + + +

- ERC-7984 is the confidential token standard built on fhEVM. Instead - of storing balances as public uint256, wrapper contracts store them as - euint64 — encrypted 64-bit integers. The plaintext is never visible on-chain; - only the token owner can decrypt it. -

-
- Key properties of ERC-7984 tokens: -
    -
  • Balances are on-chain ciphertexts — unreadable by validators, indexers, or block explorers
    • -
  • Transfer amounts are encrypted — confidential even from recipients until decrypted
    • -
  • Decryption requires the owner's EIP-712 permit (see below)
    • -
  • Underlying ERC-20 is always 1:1 collateralized in the wrapper contract
    • -
-
- -
- - {/* ════════════════════════════════════════════════════════════════ */} -
-

- This is the most common source of bugs when integrating Zama FHE tokens. - Read carefully. -

-

- FHE operates on euint64 — a 64-bit unsigned integer - with a maximum value of ~1.84 × 10¹⁹. A standard 18-decimal ERC-20 token - represents 1.0 ETH as 10¹⁸. Multiplied by any meaningful token amount, this - would overflow the 64-bit limit quickly. -

-

- Therefore, all ERC-7984 wrapper tokens use 6 decimals, regardless - of the underlying token's precision. The wrapper contract scales amounts - automatically during shielding and unshielding. -

- -
- ⚠️ Critical rule: When calling useShield, parse the - amount using the underlying token's decimals. When calling{' '} - useUnshield, always use 6 decimals (wrapper decimals). -
- -

OperationDecimals to useExample (1.0 WETH)
Shield (wrap)parseUnits(amount, underlyingDecimals){"parseUnits('1', 18)"} → 10¹⁸
Unshield (unwrap)parseUnits(amount, 6){"parseUnits('1', 6)"} → 10⁶
Display confidential balanceformatUnits(balance, 6){"formatUnits(1_000_000n, 6)"} → {"'1.0'"}

- - {/* ════════════════════════════════════════════════════════════════ */} -
-

- Reading a confidential balance requires an EIP-712 typed-data signature from the - token owner's wallet. This signature authorizes the Zama Gateway to decrypt the - ciphertext and return the plaintext value to the frontend session. -

- -
- 🚨 Security rule — NEVER auto-fire permits. Every call to{' '} - useConfidentialBalance or useConfidentialBalances with{' '} - enabled: true will immediately request a wallet signature. Always gate it - behind an explicit decryptRequested boolean state that is only set{' '} - true on user click. -
- -

How it works

-
- {[ - { n: '1', t: 'User clicks "Decrypt"', d: 'Set decryptRequested = true in your component state.' }, - { n: '2', t: 'SDK requests EIP-712 signature', d: 'The hook constructs a typed data payload and asks MetaMask/Rabby to sign it. This is off-chain — no gas, no transaction.' }, - { n: '3', t: 'Session key derived', d: 'The signature is used to derive a short-lived session key scoped to your wallet address and the specific contract.' }, - { n: '4', t: 'Zama Gateway decrypts', d: 'The Gateway uses the session key to decrypt the on-chain ciphertext. Only your account\'s ciphertexts can be decrypted with your key.' }, - { n: '5', t: 'Plaintext returned to browser', d: 'The decrypted bigint balance is returned to your component. It is never stored on-chain in plaintext.' }, - ].map((s) => ( -
-
{s.n}
-
- {s.t} -

{s.d}

-
-
- ))} -
- -
- Token selector reset: When the user changes the selected token in - your UI, reset decryptRequested synchronously in the{' '} - onChange handler — not only in a useEffect. A one-frame - delay in the effect can cause the old true value to combine with the - new token address and auto-fire a permit. -
- - { - setSelectedToken(newToken); - setDecryptRequested(false); // ← must happen in same handler, not useEffect -}; - -const { data: balance } = useConfidentialBalance({ - tokenAddress: selectedToken.erc7984Address, - enabled: decryptRequested && !!address, // ← explicit gate -});`} - /> -
- - {/* ════════════════════════════════════════════════════════════════ */} -
-

- All addresses below are sourced from the official Zama documentation and verified - against the on-chain WrappersRegistry. Blocklisted entries (suspected test/placeholder - contracts with vanity addresses) are excluded. -

- - - -

- The first 7 pairs are mock tokens with a public mint(). - The restricted ctGBP is a non-mintable pair — it does not have - a public mint function. Addresses read live from the on-chain registry; the - list above is a snapshot and may lag new registrations. -

- Use matchZamaError from @zama-fhe/sdk to classify SDK - errors into user-friendly messages. ShadowLine re-exports this via the{' '} - classifyError(err) utility in src/lib/errors.ts. -

5. Unshield when you are done

+

+ To recover your original ERC-20, go to the Wrapper page, + switch to Unshield, and enter the amount.

- Before you go further: the single most common integration bug is decimal - mismatch. Read Decimal Scaling before wiring up real - amounts — shield uses the underlying decimals, unshield always uses 6. + Decimal note: shield amounts use the underlying token's + decimals (e.g. 6 for USDC, 18 for WETH). Unshield always uses the wrapper's fixed{' '} + 6-decimal scale.

Why Autonomous AI Agents Need ShadowLine

+

+ AI agents executing on-chain trading strategies, DAO treasury management, or automated payroll + face critical vulnerabilities when holding public ERC-20 tokens: +

+
    +
  • + MEV Exploitation & Sandwiche Attacks: Searchers monitor public mempools and agent balances to front-run automated trades. +
    • +
  • + Strategy Copy-Trading: Observers can copy or counter-trade an AI agent's portfolio rebalancing in real time. +
    • +
  • + Treasury Exposure: DAO and agent operational wallets reveal sensitive cash flow and runway data. +
    • +
+

+ By wrapping public tokens into ERC-7984 confidential wrappers (cTokens) on Zama's + fhEVM, AI agents hold encrypted balances (euint64) and execute confidential transfers + completely hidden from public scrutiny. +

+ +

1. llms.txt — AI Discovery Standard

+

+ ShadowLine adheres to the emerging llmstxt.org specification. LLMs and autonomous coding agents can read our structured summaries directly: +

+
    +
  • + /llms.txt — High-level protocol summary, capabilities, and core concepts. +
    • +
  • + /llms-full.txt — Complete developer reference including smart contract ABIs, Viem code patterns, and decimal scaling rules. +
    • +
+ +

2. OpenAI & Universal AI Plugin Manifests

+

+ ShadowLine hosts standard discovery manifests, allowing AI frameworks (ChatGPT plugins, LangChain, Vercel AI SDK, Eliza) to auto-discover our REST API and query confidential asset pairs without manual schema configuration: +

+
    +
  • + /.well-known/ai-plugin.json — Plugin metadata and authentication spec. +
    • +
  • + /openapi.json — OpenAPI 3.0 specification for the /api/registry endpoint. +
    • +
+ +

3. Agent Tools SDK (`@shadowline/agent-tools`)

+

+ For developers building AI agents with TypeScript, we provide pre-built tool definitions in{' '} + src/lib/agent-tools.ts. These tools can be plugged directly into LangChain or Vercel AI SDK: +

+ + + + Critical Rule for AI Agents: When shielding (depositing), input amounts MUST use the underlying token's decimals (e.g. 6 for USDC, 18 for WETH).

While not inherently wrong, this is atypical for production token deployments and is commonly associated with test contracts. - -3. **Possible relationship to `tGBP`.** The name "bbqTGBP" contains "TGBP" as a suffix, raising the possibility that this is a variant, fork, or test deployment related to the existing `ctGBP` wrapper (`0xa873...eDD9`). If so, having both in the production registry without any disambiguation could confuse users and developers building on the registry. - -### What we did in ShadowLine - -- ShadowLine reads the `WrappersRegistry` **live on-chain** via `useListPairs({ metadata: true })` from `@zama-fhe/react-sdk`. This means any pair registered on-chain appears automatically in our app. -- We added a **manual blocklist** specifically for `cbbqTGBP` (`0xBA4cFF6ED6F7Cb2A58776dECa4E984b498446762`) to exclude it from the user-facing display. The blocklist is documented in our source code (`src/lib/registry.ts`) with a full rationale. -- If this entry is confirmed as legitimate and has a corrected name, we will remove it from the blocklist immediately. - -### Questions for the Zama team - -1. **Is `cbbqTGBP` intentional?** If so, what asset does "bbqTGBP" represent, and should it be displayed to end-users in registry explorers? -2. **Is it a test entry that should be removed from the Mainnet registry?** If this was deployed for internal testing, it may be worth deregistering it from the production registry to avoid confusion for bounty participants and future developers building on the registry. -3. **Is the documentation correct?** If the entry is legitimate but the name is wrong (e.g., it should be `ctGBP v2` or another name), the docs page at [mainnet/ethereum](https://docs.zama.org/protocol/protocol-apps/addresses/mainnet/ethereum) should be updated. - ---- - -## Observation: Dual `tGBP` Wrappers on Sepolia (Not a Bug) - -For completeness, we also note that the Sepolia testnet has **two distinct tGBP wrapper pairs**: - -| Name | Symbol | Wrapper | Underlying | Mint | -|---|---|---|---|---| -| Confidential tGBP (Mock) | `ctGBPMock` | `0xfCE5...F7CC` | `0x93c9...1442` | Public (1M limit) | -| Confidential tGBP | `ctGBP` | `0x167D...A208` | `0xf6Ef...7ff3` | Restricted | - -We understand this is **intentional** — the mock version is for developer testing (with a public `mint` function), and the non-mock version wraps the "official" testnet tGBP with restricted minting. We handle both correctly in ShadowLine: -- The mock `ctGBPMock` appears in both the registry table and the faucet (mintable). -- The restricted `ctGBP` appears in the registry table but is **excluded from the faucet** (since its underlying does not have a public `mint`). -- Both appear in the Portfolio for balance decryption. - -We mention this only because the dual-entry pattern might confuse other bounty participants — a brief note in the Sepolia address docs clarifying "the mock wrapper is for development, the non-mock wrapper wraps the real testnet asset" would be helpful. - ---- - -## Summary - -| Entry | Network | Status | Our Action | -|---|---|---|---| -| `cbbqTGBP` (`0xBA4c...6762`) | Mainnet | Suspected test/placeholder | Blocklisted in ShadowLine display | -| Dual `ctGBP` / `ctGBPMock` | Sepolia | Intentional (mock + real) | Both displayed correctly, faucet filters mock-only | - -We appreciate any clarification the Zama team can provide. This report is shared in good faith as part of our bounty development work to help improve the ecosystem documentation and registry hygiene.
