Description

Asana task

Migrates the Thorchain Savers and Thorchain Yield stake plugins off *.ninerealms.com. Those hosts are being retired on 2026-04-20 (already returning 301). Without this change Thorchain Savers + Yield stop loading positions, quoting stakes, and fetching inbound addresses.

Migration commit (Migrate Thorchain Savers and Yield endpoints off NineRealms):

• src/plugins/stake-plugins/thorchainSavers/tcSaversPlugin.tsx
  • MIDGARD_SERVERS_DEFAULT[0]: midgard.ninerealms.com → gateway.liquify.com/chain/thorchain_midgard
  • THORNODE_SERVERS_DEFAULT[0]: thornode.ninerealms.com → gateway.liquify.com/chain/thorchain_api
• src/plugins/stake-plugins/thorchainSavers/tcSaversPluginSegwit.tsx — same two line changes (file is a near-duplicate of the non-Segwit variant)
• src/plugins/stake-plugins/generic/pluginInfo/thorchainYield.ts
  • thornodeServers[0]: thornode.ninerealms.com → gateway.liquify.com/chain/thorchain_api

Lint-fix commit (Fix lint warnings in tcSaversPlugin): committing the two tcSavers* files removes them from the ESLint warning-suppression list. That promotes 4 rule findings to errors. Fixes in this commit:

• Added : void return type to updatePolicyApys (both files)
• Typed .catch(e => …) as .catch((e: unknown) => …) and guarded e.message access (both files)

Kept intact (intentional):

• ninerealmsClientId init option + x-client-id header — Liquify accepts it without issue.
• Secondary fallback midgard.thorchain.info — already off NineRealms.
• 21 remaining no-deprecated warnings (parentNetworkFee, networkFee, getReceiveAddress) — not in the suppressed-rule set so they stay as warnings; addressing them is architectural and out of scope for a URL migration.

Sibling PRs handle the actual swap plugin (edge-exchange-plugins) and the RUNE chain plugin (edge-currency-accountbased).

Testing

Curl-verified new endpoints with existing ninerealmsClientId:

• gateway.liquify.com/chain/thorchain_api/thorchain/network → 200 OK
• gateway.liquify.com/chain/thorchain_midgard/v2/health → 200 OK

Reviewer should confirm on device: open Thorchain Savers (APY loads, positions show), open Thorchain Yield (TCY position loads / stake quote resolves).

Note

Medium Risk
Switches Thorchain Savers and Yield plugins to new Midgard/Thornode base URLs, which could impact staking position loading/quoting if the gateway behavior differs or has downtime. Remaining changes are lint/type-safety fixes with low functional risk.

Overview
Updates Thorchain Savers (including Segwit variant) and Thorchain Yield stake plugins to stop using *.ninerealms.com and instead query Thorchain Midgard/Thornode via https://gateway.liquify.com/chain/*.

As part of committing these files, removes them from the ESLint ignore list and fixes newly-enforced lint issues by adding explicit void return types and safer unknown error handling in a .catch path. Also records the migration in CHANGELOG.md.
