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.

Made this proposal specifically with P256 / EIP-7212 in mind. Makes it easier to ship pure-function precompiles.

TLDR; a fallback contract gives you compatibility across chains implementing the precompile and those that haven’t yet

Noble cryptography: open-source that empowers wallets and others.

@paulm curious if you have takes on this

i agree with your comments in eth magicians that ed25519 would be nicer, but that proposal seems to have stalled out entirely

welcome to FC! 

would love to talk to you guys about this FIP and what we can do to support.

Hello Dogan is here :) I’m one of the co author of this EIP.

Thank you for your support and good words! 

Just to clarify; passkeys is only one usecase of this precompile, there are many other usecases like DNS verification and using Secure Enclave directly (Daimo and us)

It’s the most promising EIP 💪 I’m committed to push it forward

But what are Passkeys good for in crypto? You can‘t see the payload of what the app is proposing to sign. I‘m not trusting websites, I‘ve been trusting wallets. Is this flipped now?

I think it is pretty low chances of happening soon.

As one of the earlier adopters of passkeys we involved in the efforts to get p256 adopted on both L1s & L2s.

Both groups have said they would want to the other adopt it first 🫠 

But with enough noise about it hopefully they can be swayed

With largeBlob storage it’ll be possible to store any key type along with a passkey, but it can be read by the app loading it.

Not as secure as the enclave, but you don’t have to precompile the P256 curve. You can use secpk1 (as some demo wallets have done)

Can anyone give the tl;dr on the resistance to precompiles? Signature verification seems like a basic primitive

eg cosmwasm includes them for ecdsa and ed25519
