Functions

func CalcGasCost

func CalcGasCost(gasLimit uint64, gasPrice *big.Int) *big.Int

CalcGasCost calculate gas cost given gas limit (units) and gas price (wei)

func IsValidAddress

func IsValidAddress(iaddress interface{}) bool

IsValidAddress validate hex address

func IsZeroAddress

func IsZeroAddress(iaddress interface{}) bool

IsZeroAddress validate if it's a 0 address

func LogTopicHash

func LogTopicHash(fnsig string) common.Hash

LogTopicHash generates the log topic hash given the event function declaration signature

func PublicKeyBytesToAddress

func PublicKeyBytesToAddress(publicKey []byte) common.Address

PublicKeyBytesToAddress returns the public address derived from a public key

func SigRSV

func SigRSV(isig interface{}) ([32]byte, [32]byte, uint8)

SigRSV signatures R S V returned as arrays

func ToDecimal

func ToDecimal(ivalue interface{}, decimals int) decimal.Decimal

ToDecimal wei to decimals

func ToWei

func ToWei(iamount interface{}, decimals int) *big.Int
