func RecoverEthMessageSigner ¶

func RecoverEthMessageSigner(signature Signature, message []byte) (*ecdsa.PublicKey, error)

func RecoverEthMessageSignerAddress ¶

func RecoverEthMessageSignerAddress(signature Signature, message []byte) (common.Address, error)

func SignerFnFactory ¶

func SignerFnFactory(signer Signer, chainID *big.Int) func(common.Address, *types.Transaction) (*types.Transaction, error)
