fix(assets-controller): force default-track Arc's native USDC - #9869
Merged
Conversation
… its ERC20 identity Arc's native gas token is USDC, but Arc's Accounts-API balance fetch always succeeds for the ERC20 identity, which short-circuits the RPC fallback path that would otherwise be the only place writing `type: 'native'` metadata for the native asset id. Without that metadata, the zero-balance native entry `#ensureNativeBalancesDefaultZero` seeds for every chain has nothing to be recognized by, and clients that gate rendering on `assetsInfo[assetId]?.type === 'native'` (e.g. metamask-mobile's assets-migration.ts) silently drop the row until the account's first deposit triggers a different code path. Default-track the native id (`eip155:5042/slip44:5042`) instead of the `0x3600...` ERC20 identity, which is no longer a valid representation to track here.

## Explanation ## Assets Controller [13.1.3] ### Changed - Bump `@metamask/transaction-controller` from `^69.5.1` to `^69.5.2` ([MetaMask#9823](MetaMask#9823)) ### Fixed - Fix Arc native USDC never appearing until the account receives its first deposit, by default-tracking the native asset id (`eip155:5042/slip44:5042`) instead of the `0x3600...` ERC20 identity so `assetsInfo` metadata is seeded up front ([MetaMask#9869](MetaMask#9869)) - Properly filter empty (`''`) selected account group event ([MetaMask#9825](MetaMask#9825)) <!-- Thanks for your contribution!

@metamask/assets-controller@13.1.3 is now published to npm with the Arc native USDC default-tracking fix (MetaMask/core#9869), so the local .yarn/patches override against 13.1.2 is no longer needed.

For fresh SRP, when adding Arc, no
USDC(native) entry shows at all, until balance gets different from0.I couldn't find the root cause of the issue - only happening for Arc - but found that
default.tscontains instructions that pre-dates the decision of showing USDC native (instead of ERC20) on Arc.Re-using the same maps, we can force-show USDC native, overriding the still-nonunderstood behavior that led it to disappear.
Default-track the native id (
eip155:5042/slip44:5042) instead of the0x3600...ERC20 identity, which is no longer a valid representation to track here.As a result,
USDCnative on Arc is forced to be always shown in user's asset list, even when they own0USDC.Explanation

Low Risk
Narrows to default-tracked asset IDs and metadata for Arc only; no auth, pipeline, or API contract changes.
Overview
Fixes Arc native USDC missing from the asset list until the wallet receives a non-zero balance by changing how Arc default-tracked assets are registered in
defaults.ts.For
eip155:5042, the default tracked id is noweip155:5042/slip44:5042(native USDC) instead of the0x3600…ERC-20 CAIP-19 id. Pre-seeded metadata is updated totype: 'native'with 18 decimals, sobuildDefaultAssetsInfo/ default seeding populateassetsInfo(and zero balances) as soon as Arc is enabled—matching the decision to surface native USDC rather than the duplicate ERC-20 representation.The Unreleased changelog documents the user-visible fix.
