DefaultIpcPath returns the os-dependent default ipc path for clef.

func NewSigner

func NewSigner(clef ExternalSignerInterface, client Client, recoverFunc crypto.RecoverFunc, ethAddress *common.Address) (signer crypto.Signer, err error)

NewSigner creates a new connection to the signer at endpoint. If ethAddress is nil the account with index 0 will be selected. Otherwise it will verify the requested account actually exists. As clef does not expose public keys it signs a test message to recover the public key.
