Multi-chain addresses
Multi-Chain Addressing
Summary
Chain-specific address format that allows specifying both an
account and the chain on which that account intends to transact.
Chain-specific addresses take the form of user.eth:l2chain.
The target chain is resolved using a registry stored on ENS.
Why It Matters
This address format ensures Ethereum addresses specify the chain of the
recipient. This fits well in Ethereum's layer-2 roadmap to reduce user
errors such as accidentally sending funds on the wrong chain, and for
wallets to automatically bridge funds to the intended destination chain.
