 # P256 Signer
+
 This library implements the decoding and verification of a signed [Webauthn](https://www.w3.org/TR/webauthn-2/) payload following the [EIP 1271](https://eips.ethereum.org/EIPS/eip-1271) providing an implementation of Standard Signature Validation Method when the account is a smart contract.
 
 ## Contracts overview

 The `P256SignerFactory` contract is a factory for P256Signers. It allows us to have deterministic addresses for a given secp256r1 public key.

+We've updated our contracts following the audit's recommandations, see deployments: https://github.com/cometh-hq/p256-signer/pull/23

 It is the responsibility of the client to check the message signed is played only once if necessary.
