EIP to validate passkeys on-chain with a precompile: https://eips.ethereum.org/EIPS/eip-7212#motivation This would be huge for AA wallets. I'm curious if anyone has a pulse on how likely this is to pass, seems like there's usually a lot of contention around adding precompiles.

These wallet will also have seed phrases right ? Where and how would they be stored ?

Why would you need seed phrases? The seed phrase could be used purely for account recovery But ideally there wouldn’t be a seed phrase in the first place

you wouldn't be able to get a seed phrase from the passkey pk pair passkeys have built in account recovery with the provider (apple or google) but you can also have onchain social recovery ofc

But you don’t need a seed phrase from the passkey Seed phrases are just the most common key management system for blockchain However blockchains don’t require an actual seed phrase With EIP-7212 you could have boyh sec256k1 and secp256r1 keys controlling a Smart Account

Yep agreeing with all of this I thought you were saying that you could get a seed phrase from the passkey pk If passkey vendors adopt other curves as per the webauthn spec you could even use something like eddsa instead of p256 in which case I think there may be more precompile eips

There is a key pair inside of Secure Enclave and it cannot be extracted. So theoretically there is still a seed phrase but you cant get it from SE.

Well it is a key pair that can’t be extracted so it isn’t a seed phrase To make it a seed phrase (as in the set of words that people write down somewhere) you would need to extract the key and convert it to some words

Technically this is true BUT it would imply that your signing key is also your master key which is NOT how wallets work Seed phrases are representations of master keys which are used derive different private keys for different purposes Thus you can’t reverse the process from private key to seed phrase

Yep agreed, most of the times users are thinking that there is no key pair or a secret.
