Functions

func DryRunTx

func DryRunTx(client *ethclient.Client, fromAddress common.Address, toAddress common.Address, value *big.Int, data []byte, timeout time.Duration) (uint64, error)

DryRunTx locally executes a transaction with the current state of blockchain and returns estimated Gas multiplied with 1.5 and potential errors.

func DryRunTxAbi

func DryRunTxAbi(client *ethclient.Client, timeout time.Duration, fromAddress common.Address, toAddress common.Address, value *big.Int, abi *abi.ABI, method string, arguments ...any) (uint64, error)

DryRunTxAbi locally executes a transaction to method with arguments with the current state of blockchain and returns estimated Gas multiplied with 1.5 and potential errors.

func EventIDFromMetadata

func EventIDFromMetadata(metaData *bind.MetaData, eventName string) (common.Hash, error)

func FunctionSelector

func FunctionSelector(signature string) (selector [4]byte)

func GetGasPrice

func GetGasPrice(gasConfig *config.Gas, client *ethclient.Client, timeout time.Duration) (*big.Int, error)

func ParseTopic

func ParseTopic(topic string) common.Hash

func PrivateKeyToEthAddress

func PrivateKeyToEthAddress(privateKey *ecdsa.PrivateKey) (common.Address, error)

func SendRawTx

func SendRawTx(client *ethclient.Client, privateKey *ecdsa.PrivateKey, toAddress common.Address, data []byte, dryRun bool, gasConfig *config.Gas, timeout time.Duration) error

SendRawTx prepares and sends legacy transaction.

func SendRawType2Tx

func SendRawType2Tx(client *ethclient.Client, privateKey *ecdsa.PrivateKey, toAddress common.Address, data []byte, dryRun bool, gasConfig *config.Gas, timeout time.Duration) error
