Parameter Structs​

Note that fee is in hundredths of basis points (e.g. the fee for a pool at the 0.3% tier is 3000; the fee for a pool at the 0.01% tier is 100).

ExactInputSingleParams​

    struct ExactInputSingleParams {
        address tokenIn;

        uint256 deadline;
        uint256 amountIn;
        uint256 amountOutMinimum;
        uint160 sqrtPriceLimitX96;
    }

ExactInputParams​
