Uniswap

The following functions are optimized to swap on Uniswap V2 and Uniswap V3.

Uniswap V2 (official pools)

uniswapV2ExactInputSingle

Swap exactly amountIn of tokenIn for tokenOut on Uniswap V2. This functions is optimized for the official Uniswap V2 pools.

struct ExactInputSingleParams {
  uint256 amountIn;
  uint256 amountOut;
  address recipient;
  uint16 slippage;
  uint16 feeBps;
  uint48 deadline;
  address partner;
  address tokenIn;
  address tokenOut;
}

function uniswapV2ExactInputSingle(
  ExactInputSingleParams memory params,
  PermitParams calldata permit
) external payable returns (uint256 amountOut);


function uniswapV2ExactInputSinglePermit(
  ExactInputSingleParams calldata params,
  PermitParams calldata permit
) external returns (uint256 amountOut);

uniswapV2ExactInput

Swap exactly amountIn of the token path[0] for the token path[path.length - 1] on Uniswap V2 by going through the pools in path.

struct ExactInputParams {
  uint256 amountIn;
  uint256 amountOut;
  address recipient;
  uint16 slippage;
  uint16 feeBps;
  uint48 deadline;
  address partner;
  address[] path;
}

function uniswapV2ExactInput(
  ExactInputParams memory params,
  PermitParams calldata permit
) external payable returns (uint256 amountOut);

function uniswapV2ExactInputPermit(
  ExactInputParams calldata params,
  PermitParams calldata permit
) external returns (uint256 amountOut);

Uniswap V2 and compatible (Sushiswap, etc)

Swap exactly amountIn of tokenIn for tokenOut using the specified Uniswap V2-compatible pool, such as Sushiswap.

uniswapV2LikeExactInputSingle

struct ExactInputSingleParams {
  uint256 amountIn;
  uint256 amountOut;
  address recipient;
  address pool;
  uint16 feeBps;
  uint16 slippageBps;
  address partner;
  address tokenIn;
  address tokenOut;
  uint16 poolFeeBps;
  uint48 deadline;
}

function uniswapV2LikeExactInputSingle(
  ExactInputSingleParams memory params,
  PermitParams calldata permit
) external payable returns (uint256 amountOut);

function uniswapV2LikeExactInputSinglePermit(
  ExactInputSingleParams memory params,
  PermitParams calldata permit
) external returns (uint256 amountOut);

uniswapV2LikeExactInput

Swap exactly amountIn of the token tokens[0] for the token tokens[tokens.length - 1] using the Uniswap V2-compatible pools in pools. The length of pools must be one less than the length of tokens.

The array poolFeesBps specifies the pool fee for each pool in pools. The length of poolFeesBps must be the same as the length of pools.

struct ExactInputParams {
  uint256 amountIn;
  uint256 amountOut;
  uint16[] poolFeesBps;
  address recipient;
  uint16 slippageBps;
  uint16 feeBps;
  uint48 deadline;
  address partner;
  address[] tokens;
  address[] pools;
}

function uniswapV2LikeExactInput(
  ExactInputParams memory params,
  PermitParams calldata permit
) external payable returns (uint256 amountOut);

function uniswapV2LikeExactInputPermit(
  ExactInputParams memory params,
  PermitParams calldata permit
) external returns (uint256 amountOut);

Uniswap V3 and compatible (Sushiswap, etc)

Swap exactly amountIn of tokenIn for tokenOut using the specified Uniswap V3-compatible pool.

uniswapV3LikeExactInputSingle

struct ExactInputSingleParams {
  address recipient;
  address partner;
  uint16 feeBps;
  uint16 slippageBps;
  uint256 amountIn;
  uint48 deadline;
  address tokenIn;
  address tokenOut;
  uint256 amountOut;
  address pool;
}

function uniswapV3LikeExactInputSingle(
  ExactInputSingleParams memory params,
  PermitParams calldata permit
) external payable returns (uint256 amountOut);

function uniswapV3LikeExactInputSinglePermit(
  ExactInputSingleParams calldata params,
  PermitParams calldata permit
) external returns (uint256 amountOut);

uniswapV3LikeExactInput

Swap exactly amountIn of the token tokens[0] for the token tokens[tokens.length - 1] using the Uniswap V3-compatible pools. The length of pools must be one less than the length of tokens.

struct ExactInputParams {
  uint256 amountIn;
  uint256 amountOut;
  address recipient;
  uint16 slippageBps;
  uint16 feeBps;
  uint48 deadline;
  address partner;
  address[] tokens;
  address[] pools;
}

function uniswapV3LikeExactInput(
  ExactInputParams memory params,
  PermitParams calldata permit
) external payable returns (uint256 amountOut);
