Deployment with Hardhat

Using Hardhat Ignition

1. In your Hardhat project, add Remote Network to hardhat.config.js for MANTRA Dukong EVM

require("@nomicfoundation/hardhat-toolbox");

const { vars } = require("hardhat/config");

// const ALCHEMY_API_KEY = vars.get("ALCHEMY_API_KEY");

const TEST_PRIVATE_KEY = vars.get("TEST_PRIVATE_KEY");

/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
  solidity: "0.8.28",
  networks: {
    canary: {
      url: `https://evm.evm-canary.mantrachain.dev/`,
      chainId: 5887,
      accounts: [TEST_PRIVATE_KEY]
    },
  }
};

Example on how to configure variables for user-specific values in Hardhat:

$ npx hardhat vars set TEST_PRIVATE_KEY
✔ Enter value: ********************************

1. Set Up Ignition Modules:

   • Create a directory named ignition in the project's root directory.

   • Inside the ignition directory, create another directory named modules.

   • Within the modules directory, create a <YourFile>.js file.

   Example directory structure:

   ./ignition/modules/<YourFile>.js

2. Deploy:

   To tell Hardhat to connect to a specific Ethereum network, you can use the --network parameter when running any task, like this:

npx hardhat ignition deploy ./ignition/modules/Token.js --network canary

Example result from running the above command

$ npx hardhat ignition deploy ./ignition/modules/USDC.js --network canary

✔ Confirm deploy to network canary (5887)? … yes
