ECDSASig

Contract for verifying ECDSA signatures against operator keys

Implements SigManager interface using OpenZeppelin's ECDSA library

Methods

_verifyKeySignature

function _verifyKeySignature(
        address operator,
        bytes memory key_,
        bytes memory signature
    ) internal pure override returns (bool) 

Verifies that a signature was created by the owner of a key

The key is expected to be a bytes32 that can be converted to an Ethereum address

Parameters

Name	Type	Description
operator	address	The address of the operator that owns the key
key_	bytes memory	The public key to verify against, encoded as bytes
signature	bytes memory	The ECDSA signature to verify

Returns

Name	Type	Description
	bool	True if the signature was created by the key owner, false otherwise

recover

function recover(bytes32 hash, bytes memory signature) public pure returns (address) 

Recovers the signer address from a hash and signature

Wrapper around OpenZeppelin's ECDSA.recover

Parameters

Name	Type	Description
hash	bytes32	The message hash that was signed
signature	bytes memory	The ECDSA signature

Returns

Name	Type	Description
	address	The address that created the signature
