Ethereum Account Abstraction

AA experts:

~6 months ago, it was my understanding that passkey wallets weren’t viable because they use cryptography that is too expensive to verify onchain (hence EIP 7212 etc). 

But now everyone is making them. 

What changed? 🤔

EIP-4844 changed the game, imo. Gas fees reduced more significantly than we thought, which made passkey verification even w/o RIP-7212 reasonable on L2s.

RIP-7212 will accelerate the adoption, by lowering the fee even more, similar to the level of ECDSA

Oh yeah, what i wanna say was the cost of userop itself decreased significantly, as using passkey requires ERC-4337.

wasnt it relatively cheaper pre-4844 since now execution gas is a higher percentage of total gas on L2s?
