Address Encoding Features:

• EIP-55: Mixed-case checksum address encoding

  • APIs: feat(protocol): display address with eip55 checksum #19 (ref: sources code)

  • Import from Cli: feat: import addresses with EIP-55 #1340

• EIP-155: Simple replay attack protection

  jjy: Both EIP-155 and non-EIP-155 should be supported

  • If chain_id is added, it should be checked.
  • non-EIP-155 transactions are mainly to support EIP-1820. Many projects use this method to support multi-chain contracts using the same address.

  Support or not?

The EIP-1191 is in the last call, consider supporting it after it becomes final.
