Functions

func GetSolidityFunctionSig

func GetSolidityFunctionSig(in []byte) [4]byte

func Simulate

func Simulate(c SimulateCaller, block *big.Int, txHash common.Hash, from common.Address) ([]byte, error)

Simulate function gets transaction info by hash and then executes a message call transaction, which is directly executed in the VM of the node, but never mined into the blockchain. Execution happens against provided block.

func SliceTo32Bytes

func SliceTo32Bytes(in []byte) [32]byte

func ToCallArg

func ToCallArg(msg ethereum.CallMsg) map[string]interface{}

ToCallArg is the function that converts ethereum.CallMsg into more abstract map This is done for matter of making EVMClient more abstract since some go-ethereum forks uses different messages types

func UserAmountToWei

func UserAmountToWei(amount string, decimal *big.Int) (*big.Int, error)

UserAmountToWei converts decimal user friendly representation of token amount to 'Wei' representation with provided amount of decimal places eg UserAmountToWei(1, 5) => 100000

func WeiAmountToUser

func WeiAmountToUser(amount *big.Int, decimals *big.Int) (*big.Float, error)
