Variables

var FactoryAddress = common.HexToAddress("0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f")

FactoryAddress points to the uniswap factory.

var Router02Address = common.HexToAddress("0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D")

Router02Address points to the uniswap v2 02 router.

Functions

func GeneratePairAddress

func GeneratePairAddress(token0, token1 common.Address) common.Address

GeneratePairAddress generates a pair address for the given tokens

func Quote

func Quote(amount, reserve0, reserve1 *big.Int) *big.Int

Quote gets the exchange quote for a given amount of tokens and the respective pairs reserves.

Types

type Client

type Client struct {
	// contains filtered or unexported fields
}

Client allows to do operations on uniswap smart contracts.

func NewClient

func NewClient(bc *ethclient.Client) *Client

NewClient returns a new instance of uniswap client.

func (*Client) GetExchangeAmount

func (c *Client) GetExchangeAmount(amount *big.Int, token0, token1 common.Address) (*big.Int, error)

GetExchangeAmount returns the amount of tokens you'd receive when exchanging the given amount of token0 to token1.

func (*Client) GetExchangeAmountForPath

func (c *Client) GetExchangeAmountForPath(amount *big.Int, tokens ...common.Address) (*big.Int, error)

GetExchangeAmountForPath calculates the amount for a given path.

func (*Client) GetReserves

func (c *Client) GetReserves(token0, token1 common.Address) (*Reserve, error)

GetReserves retursn the available reserves in a pair

type Pair

type Pair struct {
	Token0, Token1 common.Address
}

Pair represents a token pair.

func GetPathPairs

func GetPathPairs(tokens []common.Address) []Pair

GetPathPairs takes in the given token path and returns the corresponding pairs.

type Reserve

type Reserve struct {
	Reserve0           *big.Int // Token
	Reserve1           *big.Int // QuoteToken
	BlockTimestampLast uint32
}

Reserve represents a given uniswap pair reserve
