Functions

func Sender

func Sender(signer Signer, tx *Transaction) (common.Address, error)

Sender returns the address derived from the signature (V, R, S) using secp256k1 elliptic curve and an error if it failed deriving or upon an incorrect signature.

Sender may cache the address, allowing it to be used regardless of signing method. The cache is invalidated if the cached signer does not match the signer used in the current call.

func ToBlockNumArg

func ToBlockNumArg(number *big.Int) string

ToBlockNumArg to block number arg

func ToFilterArg

func ToFilterArg(q *FilterQuery) (interface{}, error)

ToFilterArg query to filter arg
