Functions

func GeneratePrefixedHash 

func GeneratePrefixedHash(data []byte) []byte

func GetAddrPrivKeyFromKeystore 

func GetAddrPrivKeyFromKeystore(keyjson, passphrase string) (common.Address, string, error)

func IsSignatureValid added in v0.1.13 

func IsSignatureValid(signer common.Address, data []byte, sig []byte) bool

func RecoverSigner 

func RecoverSigner(data []byte, sig []byte) (common.Address, error)

func WaitMined 

func WaitMined(
	ctx context.Context,
	ec *ethclient.Client,
	tx *types.Transaction,
	opts ...TxOption) (*types.Receipt, error)

func WaitMinedWithTxHash 

func WaitMinedWithTxHash(
