ChatGPT is a Large Language Model (LLM) extremely proficient in explaining blockchain concepts, providing advice, and even generating code snippets related to web3 development. However, keep in mind that some of the code or answers it generates may be partially or completely incorrect. Access to ChatGPT does not remove the need to know the basics of blockchain development. However, even a beginner can use artificial intelligence to dramatically increase productivity.

The second point to note is that the free, public version of ChatGPT isn’t very aware of events, updates, and practices that have emerged after 2021. This can be an issue in a field such as web3 development, where everything is improving and changing at a breakneck pace. However, it is possible to get good answers if something that you’re asking is fundamental and has been stable over the years (for instance, Truffle and Solidity).

Create an Escrow Contract With Truffle and ChatGPT

To see what ChatGPT can do, we’re going to ask it to create an escrow smart contract that allows a buyer and a seller to exchange money, and we’ll have ChatGPT establish an arbiter to resolve disputes. Let’s see what Generative AI can do!

Step 1: Install MetaMask

First, we need to set up a wallet. We’ll use the MetaMask wallet—the most popular Ethereum option—and add the Sepolia test network. MetaMask is secure and easy to use.

You can download the MetaMask extension for your browser here. Then, just install and set up the wallet. You’ll be given a “secret phrase”—keep this private and safe! Never store it anywhere public.

Note: If you need background or a primer on web3, check out this previous article I wrote on learning web3/smart contracts/Solidity.

Next, click on the “Network” tab in the top-right. Click on the option to show test networks.

You should now see the Sepolia test network in the dropdown. Select that.

Step 2: Get SepoliaETH

To deploy and interact with a smart contract, you need ETH. Since we are using the Sepolia test network, we’ll need to get some Sepolia test ETH. Don’t worry—it’s free!

You can obtain free SepoliaETH from Infura’s recently released faucet here. This faucet gives up to 0.5 SepoliaETH each day for free.
