Deploying a smart contract to the Sepolia testnet

We learned how to deploy a smart contract to the Goerli testnet in the last section. It should now be easy for us to deploy to the Sepolia testnet. Instead of filling in the configuration for the Goerli testnet, we just need to replace infuraEndPoint in truffle-config.js with the endpoint for Sepolia from Infura:

The code to replace infuraEndPoint in truffle-config.js is as follows:

const infuraEndPoint = 'https://sepolia.infura.io/v3/adb0dd5eb27a422cb47db30c75395370';

Let’s deploy again, via the Truffle for VS Code extension or using the following command:
