Migration guide

Do you have a Hardhat project and you want to deploy it to AI Trader? In this page you'll find all the steps you need to do to migrate an existing Hardhat project to AI Trader.

Overview

AITrader offers multiple Hardhat plugins with different features but in this guide we'll focus on only the ones you'd need to do to migrate your project to AI Trader.

Install dependencies

Although AI Trader is compatible with Solidity and Vyper, the deployed bytecode and the deployment process is different from Ethereum or other AVM blockchains. So the fist step will be to install the compiler and deployer hardhat plugins.

Full configuration

import { HardhatUserConfig } from "hardhat/config";

import "@matterlabs/hardhat-aitrader-deploy";
import "@matterlabs/hardhat-aitrader-solc";

const config: HardhatUserConfig = {
  aisolc: {
    version: "1.3.1",
    compilerSource: "binary",
    settings: {},
  },
  defaultNetwork: "aitrader Testnet",
  networks: {
    hardhat: {
      aitrader: false,
    },
    goerli:{
      url: 'https://goerli.com/api/abcdef12345',
      aitrader: false,
    }
    mainnet:{
      url: 'https://ethereum.mainnet.com/api/abcdef12345',
      aitrader: false,
    },
    aitrader Testnet: {
      url: "https://aitrader2-testnet.aitrader.dev",
      ethNetwork: "goerli",  // or a Goerli RPC endpoint from Infura/Alchemy/Chainstack etc.
      aitrader: true,
    },
  },
  solidity: {
    version: "0.8.17",
  },
  // OTHER SETTINGS...
};

export default config;

Deploy contracts

To deploy your contracts you'd need to use the Deployer class from the hardhat-aitrader-deploy plugin. This class takes care of all the specifics of deploying contracts on aitrader.

Here is a basic deployment script for a Greeter contract:

import { utils, Wallet } from "aitrader-web3";
import * as ethers from "ethers";
import { HardhatRuntimeEnvironment } from "hardhat/types";
import { Deployer } from "@matterlabs/hardhat-aitrader-deploy";

// An example of a deploy script that will deploy and call a simple contract.
export default async function (hre: HardhatRuntimeEnvironment) {
  console.log(`Running deploy script`);

  // Initialize the wallet.
  const wallet = new Wallet("<WALLET-PRIVATE-KEY>");

  // Create deployer object and load the artifact of the contract we want to deploy.
  const deployer = new Deployer(hre, wallet);
  // Load contract
  const artifact = await deployer.loadArtifact("Greeter");

  // Deploy this contract. The returned object will be of a `Contract` type, 
  // similar to the ones in `ethers`.
  const greeting = "Hi there!";
  // `greeting` is an argument for contract constructor.
  const greeterContract = await deployer.deploy(artifact, [greeting]);

  // Show the contract info.
  console.log(`${artifact.contractName} was deployed to ${greeterContract.address}`);
}

Include your deployment script in the deploy folder and execute it runnin

# Yarn
yarn hardhat deploy-aitrader --script SCRIPT_FILENAME.ts --network aitraderTestnet

# NPM
npx hardhat deploy-aitrader --script SCRIPT_FILENAME.ts --network aitraderTestnet
