Ethereum clones
44/60 path
Adding a 44/60 EVM network is straightforward: you submit icons to the ledger-network-icons repository, and Ledger takes care of adding your network to the Crypto Asset List (CAL).
Follow the procedure in the repository README .
The repository requires signed commits. Use the -S flag: git commit -S -m "your commit message"
