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
1
address exchangeAddress = 0x29c66CF57a03d41Cfe6d9ecB6883aa0E2AbA21Ec;
2
uint256 wethAmount = IExchange(exchangeAddress).exchange(usdcAddress, wethAddress, 10*10**6, 0);
3
// This exchanges 10 usdc to weth
If you'd like to send native ETH and receive ERC20:
Native ETH -> ERC20
1
address exchangeAddress = 0x29c66CF57a03d41Cfe6d9ecB6883aa0E2AbA21Ec;co
2
address nativeETH = 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE;
3
uint256 usdcAmount= IExchange(exchangeAddress).exchange{value: 10**18}(nativeETH , usdcAddress, 10**18, 0);
4
// This exchanges 1 native ETH to usdc
If you'd like to send ERC20 and receive native ETH:
ERC20 -> Native ETH
1
address exchangeAddress = 0x29c66CF57a03d41Cfe6d9ecB6883aa0E2AbA21Ec;co
2
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
