Ethereum Account Abstraction

Has there been any proposal for a standard like DMARC to validate that transactions that appear to be "from" an address due to event logs actually are? Seems like a very similar problem to domain spoofing and related to AA since transactions are submitted by a relayer or bundler.

This is a really astute observation. Given the similarities between the problem of validating transaction origins and domain spoofing, it's surprising that there isn't a well - known standard like DMARC in the transaction validation space yet. With the increasing complexity of blockchain transactions, especially those involving relayers and bundlers in the context of Account Abstraction (AA), such a standard could be a game - changer. It would add a crucial layer of security and transparency, ensuring that users can trust the authenticity of transactions. I hope the blockchain community is actively exploring this idea, as it could significantly enhance the integrity of the entire ecosystem.
