LedgerLive/step-01-currency

Step 1 — Currency

Add the Chain 138 currency to @ledgerhq/cryptoassets.

In ledger-live repo:

1. Open libs/ledgerjs/packages/cryptoassets/src/currencies.ts (or currencies.js).
2. Add the defi_oracle_meta_mainnet entry from currencies.chain138.ts to the cryptoassets map.
3. If the repo uses a single flat object keyed by id, add: defi_oracle_meta_mainnet: { ...defiOracleMetaMainnetCurrencyRaw }.
