ERC-3770: Chain-specific addresses

ERC-3770 is a draft Ethereum standard that proposes prefixing chain-specific addresses with a human-readable chain short name, such as "shortName:address". The proposal states that as EVM-compatible chains grow, the same address may refer to an externally owned account on one chain and a smart contract on another, which could cause users to lose funds through human error, for example by sending funds to a smart contract wallet address not deployed on that chain. It notes that EIP-155 chain IDs could serve as the prefix but were designed for developer interoperability rather than display to users. The short name must come from the ethereum-lists chains repository, and the address must be ERC-55 compatible. The draft also warns that similar-looking chain short names could confuse users.
