Accrual keepers, adapter migrations, and wallet groundwork: A Week in Review

[collinsezedike]

Longer gap than usual since the last update, sorry for the quiet. Getting Meridian ready for Drips and GrantFox ate most of the available time; worth it, but it meant fewer updates here. Back to a regular cadence now. Here's everything since the last post.

Blend accrual keeper is live (#484)

Blend-backed adapters cache total_assets(), and that cache only reflects passive interest after a real accrue() transaction lands on-chain. A scheduled keeper now calls accrue() on every Blend adapter it discovers, on a 15-minute cycle, with retry and backoff on transient failures. DeFindex-backed adapters don't need this since their asset value is computed live.

Automatic protocol-yield routing, on-chain half and keeper both in (#469, #507, #509, #512)

Vaults can now move their entire position to a new adapter in a single, slippage-bounded, admin-authorized call, and a scheduled keeper that compares protocol rates and triggers that call is now in the repo too. Two things still have to land before this actually migrates anything in production: a real rate source (rate comparison is deliberately pluggable and currently always reports "unknown," see #511) and a redeploy of the live testnet vault, which predates migrate_adapter entirely (#514). Until both close, the keeper runs on schedule and does nothing, by design, not silently.

Wallet abstraction layer extracted from the Freighter flow (#487)

The wallet integration used to be Freighter-specific throughout the app. That logic now sits behind an abstraction layer, which is the groundwork multi-wallet support needs before it can start.

Correctness and security hardening

A batch of fixes landed on the money-moving paths: Blend adapter withdrawals now size off real bToken balances instead of principal (#503), the adapter cache refreshes before deposit/withdraw pricing so quotes can't go stale (#485), DeFindex withdrawals got slippage protection (#456), the keeper endpoints fail closed instead of open when Upstash env vars are missing in production (#506), and a missing rate limit on GET /vaults/:vaultId was closed (#480).

Accessibility and i18n fixes

Toasts now announce themselves to screen readers via an aria-live region (#443), AmountInput has an accessible name (#438), a variable-shadowing bug that let VaultPanel tab labels bypass translation is fixed (#474), and Blend faucet toast messages are now translated (#436).

Housekeeping

An MIT LICENSE file was added (#479, somehow missing until now), CI now verifies the actual Vercel build path on every PR instead of a proxy for it (#473), the contract-address verification check is now explicitly blocking instead of advisory (#457), and Tailwind moved to v4.


Back to building.
