Love the movement around multichain-specific ERCs. I'm contributing to the ERC-7785 for the onchain registry of chains (that would deprecate the repo-maintained, offchain chainlist.org) and I just noticed a proposal for a new ERC to simplify multichain addresses based on ENS. Both ERCs would make for a perfect, complete address routing system not only on ethereum but across any EVM chain, whether it settles on Ethereum or not. https://github.com/ethereum/ERCs/pull/669
