Functions

func ValidateEvmTransaction

func ValidateEvmTransaction(tx *ethrpc.Transaction) error

ValidateEvmTransaction checks the basics of an EVM transaction Note: these checks are to ensure the transaction is well-formed and can be safely used for further processing by zetaclient

func ValidateEvmTxLog

func ValidateEvmTxLog(vLog *ethtypes.Log, wantAddress ethcommon.Address, wantHash string, wantTopics int) error

ValidateEvmTxLog checks the basics of an EVM tx log
