Bad news! I tried to connect the YubiKey 5C to my 15Pro and it's not even supported yet. I'll need to look into the library and see if I can just call the raw Apple CryptoToken API's, but for now, looks like no iPhone/YubiKey Secure Enclave based private key.

wow wow wow, this is fascinating. Imagine you set up a Yubikey secp256r1 Secure Enclave signer AND a device/iPhone secp256r1 Secure Enclave signer…then you use both as signers in a secp256r1 verifying multisig smart contract wallet. Hyper secure, hyper self-custodial, love it!

and then obviously set up conditions on SC wallet that if tx value > x require both signers, if tx value < x only require device/iPhone signer.

This is already possible if you are happy to pay extra gas for onchain r1.

If you make the yubikey signer a webauthn credential and have a wallet that supports webauthn and direct Secure Enclave signers (none exist that I am aware of) then you can do exactly this

YESSS 🙏This is the plan! https://warpcast.com/joeblau/0x4b83f0
