## 2. Trust Wallet (trustwallet/wallet-core)

**Repo:** https://github.com/trustwallet/wallet-core  
**Action:** Add Chain 138 to the chain registry (e.g. `registry.json` or current path per their docs).

**File:** [trust-wallet-registry-chain138.json](./trust-wallet-registry-chain138.json)

**Steps:**
1. Clone trustwallet/wallet-core and follow [Trust – New EVM chain](https://developer.trustwallet.com/developer/wallet-core/newblockchain/newevmchain)
2. Add the JSON entry from `trust-wallet-registry-chain138.json` to the registry file (path may be `registry.json` or under `registry/`; check repo)
3. Run codegen: `./tools/new-evmchain dfiometa` (use registry **id**, not chainId 138; requires Rust/cargo)
4. Extend derivation tests if required
5. Build and test, then open PR with registry change + generated files
