E2E Test Selection:

The PR removes deprecated tokensChainsCache references across the codebase:

1. tokenListController.ts (DELETED): The file containing selectTokenList and selectERC20TokensByChain selectors is deleted. Confirmed no remaining imports exist in production code (only test mocks that were also cleaned up).

2. assets-list.ts (selectAsset/assetToToken refactor): The assetToToken function now gets aggregators from allTokens (the actual stored token data) instead of looking them up from tokensChainsCache. This affects token metadata display in TokenListItem, TokenDetails, and Earn components. This is a behavioral change in how token aggregators are sourced — if allTokens doesn't have aggregators populated, they'll be empty. This touches the asset list and token details views → SmokeWalletPlatform.

3. transactions/index.js (isSmartContractAddress): Removed the early-return optimization that checked tokensChainsCache for mainnet contract addresses. Now all contract address checks go through the network query path. This could affect confirmation flows where contract detection is used (ERC-20 approvals, contract interactions) → SmokeConfirmations.

4. sentry/utils.ts: Cleanup of Sentry state masking — no functional impact on app behavior.

5. Test files: Unit test updates reflecting the above changes — no direct E2E impact.

SmokeTrade is included because swap/bridge flows use token metadata (including aggregators) for token selection and display, and the selectAsset change affects how token aggregators are resolved.

SmokeConfirmations is included because isSmartContractAddress is used in transaction confirmation flows to detect contract addresses, and removing the cache shortcut changes the code path.

SmokeWalletPlatform is included because token list display and transaction history rely on selectAsset which now sources aggregators differently.

No dependency tags needed beyond these three based on the tag descriptions (SmokeTrade + SmokeConfirmations are already paired per tag description).

Performance Test Selection:
The selectAsset and assetToToken refactor changes how token aggregators are resolved — from a direct cache lookup in tokensChainsCache to a find() operation on allTokens. This could have minor performance implications for asset loading and token list rendering, particularly with large token lists. The @PerformanceAssetLoading tag covers token list rendering and balance fetching which are directly affected by the assets-list.ts selector changes.
