## Gaps and missing integrations

See **[GAPS_AND_MISSING_INTEGRATIONS.md](GAPS_AND_MISSING_INTEGRATIONS.md)** for test results, fixes applied (e.g. Step 3 Blockscout v2 API), and a checklist of possible missing pieces (tokens/CAL, swap, staking, Clear Signing, i18n, E2E tests, etc.).

## Usage

1. Submit the [Ledger form](https://tally.so/r/mORpv8) and wait for approval.
