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_eth_mainnet: {
      url: process.env.LIGHTBRIDGE_RPC_BOBAETHMAINNET ?? 'https://mainnet.boba.network',
    },
    boba_bnb_mainnet: {
      url: 'https://boba-bnb.gateway.tenderly.co',
    },
    boba_sepolia: {
      url: 'https://sepolia.boba.network',
    },
    boba_bnb_testnet: {
      url: 'https://boba-bnb-testnet.gateway.tenderly.co',
    },
  },
  etherscan: {
    apiKey: {
      boba_eth_mainnet: "boba", // not required, set placeholder
      boba_bnb_mainnet: "boba", // not required, set placeholder
      boba_bnb_testnet: "boba", // not required, set placeholder
      boba_sepolia: "boba", // not required, set placeholder
    },
     customChains: [
       {
         network: "boba_eth_mainnet",
         chainId: 288,
         urls: {
           apiURL: "https://api.routescan.io/v2/network/mainnet/evm/288/etherscan",
           browserURL: "https://bobascan.com"
         },
       },
       {
         network: "boba_bnb_mainnet",
         chainId: 56288,
         urls: {
           apiURL: "https://api.routescan.io/v2/network/mainnet/evm/56288/etherscan",
           browserURL: "https://bobascan.com"
         },
       },
       {
         network: "boba_sepolia",
         chainId: 28882,
         urls: {
           apiURL: "https://api.routescan.io/v2/network/testnet/evm/28882/etherscan",
           browserURL: "https://testnet.bobascan.com"
         },
       },
       {
         network: "boba_bnb_testnet",
         chainId: 9728,
         urls: {
           apiURL: "https://api.routescan.io/v2/network/testnet/evm/9728/etherscan",
           browserURL: "https://testnet.bobascan.com"
         },
       }
    ],
  }
};

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"

Alternatively you may want to use Sourcify to verify your contracts.
