Verifying Contracts

Learn how to verify smart contracts on Boba
The Boba Explorers support verifying smart contracts via the hardhat-etherscan plug
​
Installation
npm install --save-dev @nomiclabs/hardhat-etherscan
And add the following statement to your hardhat.config.js:
require("@nomiclabs/hardhat-etherscan");
Or, if you are using TypeScript, add this to your hardhat.config.ts:
import "@nomiclabs/hardhat-etherscan";
Usage
You need to add the following Etherscan config to your hardhat.config.js file:
module.exports = {
  networks: {
    'boba-mainnet': {
      url: 'https://mainnet.boba.network',
    },
    bobabeam: {
      url: 'https://bobabeam.boba.network',
    },
    bobaavax: {
      url: 'https://avax.boba.network',
    },
    bobabnb: {
      url: 'https://bnb.boba.network',
    },
    bobaopera: {
      url: 'https://bobaopera.boba.network',
    },
  },
  etherscan: {
    apiKey: {
      'boba-mainnet': process.env.BOBA_MAINNET_KEY,
      bobabeam: 'NO_KEY_REQUIRED',
      bobaavax: 'NO_KEY_REQUIRED',
      bobabnb: 'NO_KEY_REQUIRED',
      bobaopera: 'NO_KEY_REQUIRED',
    },
     customChains: [
      {
        network: 'boba-mainnet',
        chainId: 288,
        urls: {
          apiURL: 'https://api.bobascan.com/api',
          browserURL: 'https://bobascan.com',
        },
      },
      {
        network: 'bobabeam',
        chainId: 1294,
        urls: {
          apiURL: 'https://blockexplorer.bobabeam.boba.network/api',
          browserURL: 'https://blockexplorer.bobabeam.boba.network/',
        },
      },
      {
        network: 'bobaavax',
        chainId: 43288,
        urls: {
          apiURL: 'https://blockexplorer.avax.boba.network/api',
          browserURL: 'https://blockexplorer.avax.boba.network/',
        },
      },
      {
        network: 'bobabnb',
        chainId: 56288,
        urls: {
          apiURL: 'https://blockexplorer.bnb.boba.network/api',
          browserURL: 'https://blockexplorer.bnb.boba.network/',
        },
      },
      {
        network: 'bobaopera',
        chainId: 301,
        urls: {
          apiURL: 'https://blockexplorer.bobaopera.boba.network/api',
          browserURL: 'https://blockexplorer.bobaopera.boba.network/',
        },
      },
    ],
  },
  }
};
Lastly, run the verify task, passing the address of the contract, the network where it's deployed, and the constructor arguments that were used to deploy it (if any):
npx hardhat verify --network mainnet DEPLOYED_CONTRACT_ADDRESS "Constructor argument 1" "Constructor argument 2"
​
On contract creation, you will receive an address to check a pending transaction. If it does not redirect you to block explorer, verify you are on the chain where the contract was deployed, and type the contract's address into the search bar. Your contract details should come up.
Once you have provided all the necessary information, hit 'Verify & Publish'
