Variables

var (
	// Only a few fee tiers are possible in UniswapV3. They are represented in percentage.
	// https://uniswapv3book.com/docs/milestone_5/swap-fees/#accruing-swap-fees
	StableTier   feeTier = 0.05 // 500
	StandardTier feeTier = 0.3  // 3_000
	ExoticTier   feeTier = 1    // 10_000
)

var (
	// The amount of token to mint when deploying the ERC20 contract.
	MintAmount = big.NewInt(999_999_999_999_999_999)
)

var SwapAmountInput = big.NewInt(1_000)

The amount of inbound token given as swap input.

Functions

func ExactInputSingleSwap

func ExactInputSingleSwap(tops *bind.TransactOpts, swapRouter *uniswapv3.SwapRouter02, poolConfig PoolConfig, amountIn *big.Int, recipient common.Address, nonce uint64) error

ExactInputSingleSwap performs a UniswapV3 swap using the `ExactInputSingle` method which swaps a fixed amount of one token for a maximum possible amount of another token. The direction of the swap is determined by the nonce value.

func PercentageToUniswapFeeTier

func PercentageToUniswapFeeTier(p float64) *big.Int

PercentageToUniswapFeeTier takes a percentage and returns the corresponding UniswapV3 fee tier.

func SetupLiquidityPool

func SetupLiquidityPool(ctx context.Context, c *ethclient.Client, tops *bind.TransactOpts, cops *bind.CallOpts, uniswapV3Config UniswapV3Config, poolConfig PoolConfig, recipient common.Address) error

SetupLiquidityPool sets up a UniswapV3 liquidity pool, creating and initializing it if needed, and providing liquidity in case none exists.

Types

type Contract

type Contract interface {
	uniswapv3.UniswapV3Factory | uniswapv3.UniswapInterfaceMulticall | uniswapv3.ProxyAdmin | uniswapv3.TickLens | uniswapv3.NFTDescriptor | uniswapv3.NonfungibleTokenPositionDescriptor | uniswapv3.TransparentUpgradeableProxy | uniswapv3.NonfungiblePositionManager | uniswapv3.V3Migrator | uniswapv3.UniswapV3Staker | uniswapv3.QuoterV2 | uniswapv3.SwapRouter02 | uniswapv3.WETH9 | uniswapv3.Swapper
}

Contract represents a UniswapV3 contract (including WETH9 and Swapper).

type ContractConfig

type ContractConfig[T Contract] struct {
	Address  common.Address
	Contract *T
}

ContractConfig represents a contract and its address.

func DeployERC20

func DeployERC20(ctx context.Context, c *ethclient.Client, tops *bind.TransactOpts, cops *bind.CallOpts, uniswapV3Config UniswapV3Config, tokenName, tokenSymbol string, amount *big.Int, recipient common.Address, tokenKnownAddress common.Address) (tokenConfig ContractConfig[uniswapv3.Swapper], err error)

Deploy an ERC20 token.

type PoolConfig

type PoolConfig struct {
	Token0, Token1     ContractConfig[uniswapv3.Swapper]
	ReserveA, ReserveB *big.Int
	Fees               *big.Int
}

PoolConfig represents the configuration of a UniswapV3 pool.

func NewPool

func NewPool(token0, token1 ContractConfig[uniswapv3.Swapper], fees *big.Int) *PoolConfig

Create a new `PoolConfig` object.

type UniswapV3Addresses

type UniswapV3Addresses struct {
	FactoryV3, Multicall, ProxyAdmin, TickLens, NFTDescriptorLib, NonfungibleTokenPositionDescriptor, TransparentUpgradeableProxy, NonfungiblePositionManager, Migrator, Staker, QuoterV2, SwapRouter02, WETH9 common.Address
}

UniswapV3Addresses is a subset of UniswapV3Config. It represents the addresses of the whole UniswapV3 configuration, including WETH9.

type UniswapV3Config

type UniswapV3Config struct {
	FactoryV3                          ContractConfig[uniswapv3.UniswapV3Factory]
