WebAuthn Demo
Imagine a world where signing crypto transactions was as seamless as using ApplePay. Well that day is coming
soon. All the pieces are in place. We tried fitting some of the existing Lego pieces together, to see how far

your device or on your phone, and then using that key to sign transactions, and send them to a Go backend
where they are cryptographically verified using the secp256r1 (P256) curve.
