Hey @aliceto thanks for the comment.
If this is combined with ERC-8091, would it also be possible to associate privacy addresses with it?
So long as ERC-8091 addresses can be structured into an ERC-7930 address format, then they’re natively compatible with this specification. Since the ERC-8091 address schema is not eip155 compatible, I think a purpose built CAIP-350 profile would be needed.
