Note
Medium Risk
Touches transaction-pay quoting/totals and stablecoin detection, which can affect displayed costs and max-amount behavior across networks; mitigated by being a targeted patch and limited app-side changes.
Overview
Fixes transaction pay quote/total calculations by patching
@metamask/transaction-pay-controller12.1.0 rather than bumping the dependency.The patch centralizes a multi-chain
STABLECOINSlist, treats stablecoins as $1 in token fiat-rate logic, and changestargetAmountacross quotes/totals to be aFiatValuesummed viasumFiat(avoiding incorrect max/totals math). Relay quote normalization now accounts forfees.subsidizedby zeroing provider fees when subsidized and optionally including the subsidized amount in the computed target fiat value; Bridge normalization alignstargetAmountto fiat-only as well.On the mobile side,
useTokenFiatRatesnow uses a stablecoin allowlist (Mainnet/Arbitrum/Linea/Polygon) to return a fixed USD rate of1, and the related unit test is generalized accordingly. The Transaction Pay controller messenger drops the unusedTokenListController:getStateaction, andpackage.json/yarn.lockare updated to consume the patched controller via Yarn’spatch:protocol.Written by Cursor Bugbot for commit 61d257e.
