Signers

These abstract modules handle signer storage, the installation lifecycle, and core signature validation primitives. See the Validators page for the ready-to-use validator implementations built on top of them.

ERC7579ECDSA

Manages a single EOA signer per account and exposes _validateECDSA for downstream validation logic. Installation data encodes the signer as a packed 20-byte address.

address currentSigner = module.signer(account);
module.setSigner(account, newSigner); // must be called by the account

ERC7579P256

Manages a single P256 (secp256r1) public key per account as (qx, qy) coordinates and exposes _validateP256. Installation data encodes the key as 64 packed bytes.

(bytes32 qx, bytes32 qy) = module.signer(account);
module.setSigner(account, newQx, newQy); // must be called by the account

ERC7579WebAuthn

Extends ERC7579P256 with WebAuthn authentication by adding _validateWebAuthn. Signatures must be ABI-encoded WebAuthn.WebAuthnAuth structs. Signer storage and management are inherited from ERC7579P256.
