Functions ¶
func CalcGasCost ¶
CalcGasCost calculate gas cost given gas limit (units) and gas price (wei)
func ConvertAddress ¶
converts an string ethereum address to eth address addr: 0x71c7656ec7ab88b098defb751b7401b5f6d8976f
func GenerateNewKey ¶
func GenerateNewKey() (*ecdsa.PrivateKey, error)
generates new ethereum ECDSA key This is the private key which is used for signing transactions and is to be treated like a password and never be shared, since who ever is in possesion of it will have access to all your funds.
func GetAddressFromPrivateKey ¶
func GetAddressFromPrivateKey(privateKey *ecdsa.PrivateKey) fixtures.Address
get ethereum address from its private key
func GetPrivateKeyAsEthString ¶
func GetPrivateKeyAsEthString(privateKey *ecdsa.PrivateKey) string
get the private key encoded as 0x..... string
func GetPrivateKeyBytes ¶
func GetPrivateKeyBytes(privateKey *ecdsa.PrivateKey) []byte
get the bytes of private key
func GetPublicKey ¶
func GetPublicKey(privateKey *ecdsa.PrivateKey) *ecdsa.PublicKey
get the bytes of private key
func GetPublicKeyAsEthString ¶
The public address is simply the Keccak-256 hash of the public key and then we take the last 40 characters (20 bytes) and prefix it with 0x
func GetPublicKeyBytes ¶
get the bytes of public key
func IsValidAddress ¶
check if an address is syntactically valid or not example address: 0x71c7656ec7ab88b098defb751b7401b5f6d8976f
func IsValidAddressLow ¶
check if an address is syntactically valid or not example address: 0x71c7656ec7ab88b098defb751b7401b5f6d8976f
func IsValidBlockHash ¶
a block hash is valid only if: starts with 0x is hexadecimal string of 32 bytes encoded data (64 bytes as hex string) + 0x prefix example: 0xb903239f8543d04b5dc1ba6579132b143087c68db1b2168786408fcbce568238
func IsValidBlockNumber ¶
check if the input string represents a valid block number allowed block numbers are: The following options are possible for the defaultBlock parameter:
HEX String - an integer block number String "earliest" for the earliest/genesis block String "latest" - for the latest mined block String "pending" - for the pending state/transactions
func IsValidHexPrivateKey ¶
func IsValidHexSignature ¶
func IsZeroAddress ¶
IsZeroAddress validate if it's a 0 address
func LogTopicHash ¶
LogTopicHash generates the log topic hash given the event function declaration signature
