- Added swap support involving EXA on Base.
- Implemented chain-aware EXA token discovery and balance handling across supported networks.

Changes

EXA chain support

Layer / File(s)	Summary
Optional EXA address wiring `common/wagmi.config.ts`	Loads the optional EXA deployment and exposes its address through generated chain address exports.
Chain-aware LI.FI token flows `src/utils/lifi.ts`	Uses the active chain and optional EXA address when fetching LI.FI tokens and balances, with case-insensitive deduplication and fallback behavior.
Per-chain allowlist and release metadata `src/utils/lifi.ts`, `.changeset/*`	Stores allowlisted tokens by chain and records patch releases for 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.

Keep base swap tokens on the deployed allowlist

For Base, this newly added allow list is not the same as the deployed ProposalManager allowlist: I checked contracts/broadcast/ProposalManager.s.sol/8453/run-latest.json, and 0x04C0599Ae5A44757c0af6F9eC3b93da8976c150A (plus several other added Base addresses) is absent from the constructor targets. When a user selects one of these tokens as an external source, ExaPlugin.swap first calls approve on that token through the account, and ProposalManager.preExecutionChecker rejects non-allowlisted targets, so the UI will quote and enable swaps that revert. Keep this list to the deployed ProposalManager targets or update the on-chain allowlist.
