OZWebAuthnSignature
public struct OZWebAuthnSignature : OZSmartAccountSignature, HashableA WebAuthn signature produced by a passkey authentication ceremony.
Carries the complete attestation data required to verify biometric or security-key authentication. The signature must be in compact format (64 bytes) with a normalised low-S value to avoid signature malleability.
Field ordering in the SCVal map is alphabetical and is required for contract compatibility:
authenticator_dataclient_datasignature
The map key is client_data, not client_data_json.
-
Raw authenticator data from the WebAuthn ceremony.
