The bridge is down on the live site

Every quote is refused. POST https://openlaunch.lol/api/bridge/quote returns HTTP 502 The bridge returned an unverifiable quote on every route. It has most likely done so since Relay switched routers on 2026-10-26 (I confirmed the failure on 2026-11-10). Nothing is sent when this happens: the check fails closed.

Why

Relay made its v3.2 router the default on 2026-10-26 at 10 AM ET (contract addresses, "Migrating to the new router"). Since then:

  • GET /chains reports contracts.erc20Router = 0x0729e2a4716d9f7dd17858d5d504426d228697f7 on Base, Robinhood Chain and Arc
  • every order names that router in output.extraData and in both refunds' extraData

validation.ts pinned only the v3 router (0xb92fe925dc43a0ecde6c8b1a2709c170ec4fff4f), so the chain catalogue check failed before the quote was even read.

The change

  • RELAY_ROUTERS holds both addresses, v3.2 and v3. Relay keeps both live through the transition and asks integrators who pin addresses to allow both.
  • The chain catalogue's erc20Router, the order's output.extraData and each refund's extraData must each name one of the two. Anything else is still refused.
  • Nothing else moves: the depository pin, the deposit calldata, recipients, refund destinations, minimum output, deadlines and the 5% limits are untouched.
  • docs/bridge.md records the outage and the fix.

Both addresses are in the "Cancun" column of Relay's contract-versions table on the page linked above. Please check them against it before approving: pr-guard flags them as on-chain addresses for that reason.

Checked

  • Read-only live tests (RUN_BRIDGE_LIVE_TESTS=1, Relay's public example address, no wallet): 0 of 10 routes passed before, 10 of 10 pass after.
  • New unit tests: v3.2 and v3 are accepted in the catalogue and the order, in any letter case; a router Relay never published is refused in the catalogue, the output and either refund; a bare address or a padded word with extra bytes is refused.
  • Bridge unit tests: 84 pass. Typecheck and lint are clean.
  • No wallet signed anything and no funds moved. A small real transfer after deploy is still worth doing.

Not in this pull request

The live tests are opt-in, so nothing noticed this for two weeks. A scheduled run of relay.live.test.ts would have caught it the same day. That is a workflow change, so it is left to the maintainers.

Summary by CodeRabbit

  • Bug Fixes

    • Bridge quotes now support both published Relay router versions across chain metadata, order output, and refund destinations. Other router addresses and malformed values remain rejected.
  • Documentation

    • Updated bridge documentation with details about Relay router version support and route testing.

Relay made its v3.2 router the default on 2026-10-26: Get Chains reports
it as contracts.erc20Router and every order names it in extraData. Only
the v3 router was pinned, so since then every quote has been refused as
unverifiable and the bridge could not be used. Nothing was sent; the
check fails closed.

Both routers are allowed now, as Relay asks of integrators who pin them.
The chain catalogue, the order's output and both refunds must each name
one of the two. The depository, the deposit calldata and every other
check are unchanged.

Walkthrough

Relay router validation now accepts either of two published addresses in chain metadata, quote output, and refund data. Tests cover both routers, mixed-router cases, address casing, and invalid router data. The bridge documentation records the change and related route test results.

Changes: Relay router validation

Layer / File(s) Summary
Allowlist and validation coverage
app/src/lib/bridge/validation.ts, app/src/lib/bridge/validation.test.ts, docs/bridge.md
Validation uses a two-address allowlist for chain metadata, quote output, and refund data. Tests cover accepted routers and reject unpublished routers and malformed output data. Documentation records the v3.2 update, unchanged deposit checks, and read-only route test results.
