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? 🤔

Hmm not sure your source 6 months ago. Computation was actually cheaper then pre 4844. < $0.01 for passkey verification onchain.

Yeah I was probably just thrown off by the discussion around eip7212. I thought it was more critical than it is.
