ExampleMakerOrder

Place a maker order for WETH9

function placeMakerOrderForWETH9(uint128 amount) external returns (uint256 orderId);

Place a maker order for USDC

function placeMakerOrderForUSDC(uint128 amount) external returns (uint256 orderId);

ExampleSwap

Single-Hop-Swaps a specified amount of USDC for as much as possible of WETH9

function exactInputSingle(uint256 amountIn, uint256 amountOutMinimum) external returns (uint256 amountOut);

Single-Hop-Swaps as little as possible of WETH9 for a specified amount of USDC

function exactOutputSingle(uint256 amountOut, uint256 amountInMaximum) external returns (uint256 amountIn);

Multi-Hop-Swaps a specified amount of USDC for as much as possible of WETH9

function exactInput(uint256 amountIn, uint256 amountOutMinimum) external returns (uint256 amountOut);

Multi-Hop-Swaps as little as possible of WETH9 for a specified amount of USDC

function exactOutput(uint256 amountOut, uint256 amountInMaximum) external returns (uint256 amountIn);
