[Continuing the discussion from Chain-specific addresses]
@vid mentioned in the post above that a addressing standard for transaction hashes which includes the chain it’s on would be helpful. I answered above that there is a draft “CAIP” (chain-agnostic IP, using the CASA chain-specification URI format) which might be useful to revive for cross-VM use-cases, or just useful to copy-paste into a simpler EVM-only EIP achieving the same ends. Comment if you’ve been looking for such a thing or would be interested in prototyping/coauthoring an EIP and/or a CAIP on the subject!
