Be sure to respect all the necessary requirements present in V3

Swapping Tokens

Use the provided swapTokens function to swap ETH for USDC:

Open the index.js file in your editor.
Replace the placeholder values in the main() function:

async function main() {
  try {
    console.log('Initializing wallet...');

    // Swap example
    const swapParams = {
      tokenIn: process.env.IN_ADDRESS,
      tokenOut: process.env.OUT_ADDRESS,
      recipient: wallet.address,
      amountIn: ethers.utils.parseUnits("0.001", 18),
      amountOutMinimum: ethers.utils.parseUnits("0", 8), // Minimum USDC expected,
    };

    console.log('Swapping tokens...');
    const receipt = await exactInputSingleSwap(provider, wallet, swapParams.amountIn, swapParams.recipient, swapParams.amountOutMinimum, swapParams.tokenIn, swapParams.tokenOut);
    console.log('Swap completed! Transaction hash:', receipt.transactionHash);
  } catch (error) {
    console.error('An error occurred:', error);
  }
}

Note that in order to execute the swap correctly, you need to provide the decimals of each token you wish to swap

Run the script:

node index.js
