Neural networks, large language models and particularly ChatGPT have become the most exciting topic of recent years. You’ve probably already asked ChatGPT to write a poem, write a song or explain string theory in simple language. But this is far from the only way this tool can be used. AI can become an effective aid in work and training.<\/p>\n\n\n\n

In this article we will tell you how web3-developers can use ChatGPT to their advantage today: for quick research, improving smart contract development, fixing bugs and practicing programming skills. If used properly, an AI can speed up smart contracts writing by 10 times.<\/p>\n\n\n

Getting started with ChatGPT <\/h2><\/div>\n\n\n

Currently, ChatGPT can be used for free via the web interface, so that’s what we’ll do. Create an account in OpenAI and get to the Welcome to ChatGPT page. It looks something like this:<\/p>\n\n\n

Now let’s try out four ways ChatGPT  can help with web3 development:<\/p>\n\n\n\n

  2. Writing smart contract code<\/li>\n\n\n\n
  3. Bug fixing and testing<\/li>\n\n\n\n
  4. Programming skills training<\/li>\n<\/ol>\n\n\n

    1. Consulting with ChatGPT <\/h2><\/div>\n\n\n

    Usually, when a problem with code arises, developers go to StackOverflow and look at the documentation for the language, library or tool they are using, or just google it. It brings results but takes a lot of time.ChatGPT is a simpler alternative. It immediately gives a detailed answer with all the nuances. NeuralNet is well versed in web3 development and knows most of the well-known tools like Solidity, Infura, Ethers and MetaMask. It’s like having a more experienced mentor to whom you can ask any questions and he won’t send you to “learn the math”. For example, let’s ask ChatGPT about the meaning of the keyword “payable”:<\/p>\n\n\n

    Can you explain the use of the \u201cpayable\u201d keyword in the Solidity language? Please give an example showing its usage.<\/span><\/p> <\/div>\n <\/div><\/div>\n\n\n

    You\u2019ll get a response like this:<\/p>\n\n\n

    \n \t

    In Solidity, the “payable” keyword is used to specify that a function can receive Ether (the cryptocurrency used on the Ethereum blockchain) as part of a transaction.\u00a0<\/span><\/p>\n

    When a function is marked as payable, it means that when someone calls that function, they can send Ether along with their transaction, which can then be stored in the contract’s address. Without the “payable” keyword, a function cannot receive Ether and any transaction that tries to send Ether to it will fail.\u00a0<\/span><\/p>\n

    Here’s an example of a simple Solidity contract with a payable function:<\/span><\/p>\n

    “`<\/span><\/p>\n

    contract MyContract {<\/span><\/p>\n

    \u00a0mapping(address => uint256) public balances;<\/span><\/p>\n

    \u00a0function deposit() external payable\u00a0<\/span><\/p>\n

    balances[msg.sender] += msg.value;<\/span><\/p>\n

    \u00a0\u00a0\u00a0\u00a0}<\/span><\/p>\n

    }<\/span><\/p>\n

    “`<\/span><\/p>\n

    In this contract, we define a mapping called “balances” that stores the balance of each address that interacts with the contract. The “deposit” function is marked as payable, which means that when someone calls it, they can send some amount of Ether along with their transaction.<\/span><\/p>\n

    The function then adds the amount sent by the caller (accessed via the “msg.value” variable) to their balance in the “balances” mapping.\u00a0<\/span><\/p>\n

    Note that in order to use the “payable” keyword, the contract must have a fallback function that can handle unexpected incoming transactions. If the contract does not have a fallback function, any transactions that send Ether to it will fail.<\/span><\/p> <\/div>\n <\/div><\/div>\n\n
