Coinbase Smart Wallet session key demo! Session keys combine the enhanced UX of embedded wallets with the benefits of a unified account.

This video shows a demo and goes over some of the thinking behind our approach.

We're excited to get this in the hands of developers, so reach out to me if you're interested in experimenting with this and I'd be happy to help you get setup.

our initial version of this involved passkeys that were tied to the app’s domain. i can still imagine that being a valid use case to give users a more familiar signing experience that involves biometrics etc to be sure before submission.

other than that our account contract supports both so might as well support both types as session keys as well, up to the app to decide.

what's the case for using p256 in this instance? i.e. why pay the extra gas as compared to EOA
