Functions

func CalculatePoolAddress

func CalculatePoolAddress(tokenA, tokenB, factoryAddr common.Address, poolInitCodeStr string) (poolAddr common.Address, err error)

CalculatePoolAddress calculate uniswapV2 like pool address from token and pool address and pool init code

func CalculatePoolAddressV2

func CalculatePoolAddressV2(token0, token1 string) (pairAddress common.Address, err error)

CalculatePoolAddressV2 calculate uniswapV2 pool address offline from pool tokens

func CalculatePoolAddressV3

func CalculatePoolAddressV3(tokenA, tokenB string, fee *big.Int) (poolAddress common.Address, err error)

CalculatePoolAddressV3 calculate uniswapV3 pool address offline from pool tokens and fee

func EncodePath

func EncodePath(path []common.Address, fees []int) (encoded []byte, err error)

EncodePath encode path to bytes

func MultiCall

func MultiCall(client *ethclient.Client, methodName string, opts *bind.CallOpts, multiCallParam []Multicall2Call) (out []interface{}, err error)
