Interacting with the Exchange

Import the interface, exchange. That's it!

IExchange.sol

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.11;

interface IExchange{
    function exchange(
        address from,
        address to,
        uint256 amountIn,
        uint256 minAmountOut
    ) external payable returns (uint256);
}

Import the interface above, then assuming that you have given ERC20 approval to the exchange,

If you'd like to send ERC20 and receive ERC20:

ERC20 -> ERC20

address exchangeAddress = 0x29c66CF57a03d41Cfe6d9ecB6883aa0E2AbA21Ec;
uint256 wethAmount = IExchange(exchangeAddress).exchange(usdcAddress, wethAddress, 10*10**6, 0);
// This exchanges 10 usdc to weth 

If you'd like to send native ETH and receive ERC20:

Native ETH -> ERC20

address exchangeAddress = 0x29c66CF57a03d41Cfe6d9ecB6883aa0E2AbA21Ec;co
address nativeETH = 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE;
uint256 usdcAmount= IExchange(exchangeAddress).exchange{value: 10**18}(nativeETH , usdcAddress, 10**18, 0);
// This exchanges 1 native ETH to usdc

If you'd like to send ERC20 and receive native ETH:

ERC20 -> Native ETH

address exchangeAddress = 0x29c66CF57a03d41Cfe6d9ecB6883aa0E2AbA21Ec;co
address nativeETH = 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE;
receive() external payable {}
uint256 nativeWETH= IExchange(exchangeAddress).exchange(usdcAddress, nativeETH, 10*10**6, 0);
// This exchanges 10 usdc to native WETHI

If you find that it is reverting, please check the two causes below: 1. Not enough ERC20 approval to transfer tokens

2. No route preconfigured in the exchange
