Walkthrough

Optional EXA deployment addresses are added to generated chain configuration. LI.FI token and balance handling becomes chain-aware, and allowlists incorporate generated addresses and protocol markets. Swap and funding queries use market-scoped cache keys, with Changesets recording package patch releases.

Changes

Chain-aware EXA and swap support

Layer / File(s)	Summary
Optional EXA address wiring `common/wagmi.config.ts`, `.changeset/clever-memes-do.md`	Loads an optional EXA deployment and emits its address through the generated Wagmi address mapping.
Chain-aware LI.FI token flows `src/utils/lifi.ts`	Resolves EXA per chain, deduplicates token results, enriches balances when configured, and builds allowlists from generated addresses and protocol markets.
Protocol-scoped swap allowlists `src/components/swaps/Swaps.tsx`, `src/components/shared/FundingAlert.tsx`	Passes current protocol markets to allowlist retrieval and includes them in React Query cache keys.
Package release metadata `.changeset/nice-moles-invent.md`, `.changeset/sour-items-strive.md`	Records patch releases for mobile EXA and Base swap support.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Code Review

This pull request adds support for EXA and swaps on the Base network. It updates the wagmi configuration to load the EXA deployment and refactors the Li.Fi utility to dynamically use the EXA address instead of a hardcoded Optimism address, splitting the token allowlist by chain ID. The review feedback highlights two issues: a potential runtime TypeError in balancesOptions due to token.amount being a string instead of a bigint, and a case-sensitivity issue in the allowlist lookup because of a lowercase address entry.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
