Thanks for your answer! My question is because I know that ZKSync has native AA so any user can pay gas in tokens different than eth, but I've never seen this in optimistic rollups like arbitrum or optimism

Yes! And I think this is our best hope for native AA. The ETH roadmap seems to agree... I believe we'll need to prove out and battle test implementations on L2 to merit inclusion upstream.
