- Add CHAIN138_ALIGNMENT_AUDIT_2026-04-18.md: drift report covering 67 unique Chain-138 addresses from 7 canonical sources, cross-checked against on-chain state at https://rpc-core.d-bis.org (chainId 0x8a / 138). - Add docs/data/chain138-alignment.json: structured findings for downstream tooling. - Banner CHAIN138_TOKEN_ADDRESSES.md as DEPRECATED (only 5 of 15+ tokens, 0 of 43 infrastructure contracts). Findings highlights: - 64 of 67 referenced addresses are live on-chain; 3 ghosts (in allowlist only). - 61 deployed contracts are missing from CHAIN138_TOKEN_ADDRESSES.md. - WETH9 genesis slot (0xC02aaA39...Cc2) is a non-ERC20 shim (decimals=0); real WETH9 is at 0x3304b747...E6 per smom/docs/ADDRESS_MAPPING.md. - WETH10 at canonical 0xf4BB2e28...A9F works (18 decimals, 'Wrapped Ether v10'). - 15 compliant fiat/metal tokens (cEURC, cGBPC, cAUDC, cJPYC, cCHFC, cCADC, cXAUC, cXAUT, cEURT, cGBPT, plus non-compliant-wrapper USDT/USDC) all live on-chain, all absent from CHAIN138_TOKEN_ADDRESSES.md. Recommended follow-ups listed in the audit doc.

Gaps and missing integrations
See 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
- Submit the Ledger form and wait for approval.
- Fork/clone LedgerHQ/ledger-live and optionally LedgerHQ/wallet-api.
