hardhat.config.js file to include the Base Mainnet configuration:language="language-javascript"require('dotenv').config();-a1b2c3- require('@nomiclabs/hardhat-ethers');-a1b2c3--a1b2c3- module.exports = {-a1b2c3- solidity: "0.8.0",-a1b2c3- networks: {-a1b2c3- base: {-a1b2c3- url: `https://mainnet.base.org/v1/rpc`,-a1b2c3- accounts: [`0x${process.env.PRIVATE_KEY}`]-a1b2c3- }-a1b2c3- }-a1b2c3- };
This configuration allows Hardhat to connect to the Base Mainnet using the specified RPC URL and your wallet's private key.
Once your Hardhat environment is configured, you can deploy your smart contracts to the Base Mainnet. Follow these steps to execute the deployment process:
contracts directory. For example, create a MyContract.sol file:language="language-solidity"// SPDX-License-Identifier: MIT-a1b2c3- pragma solidity ^0.8.0;-a1b2c3--a1b2c3- contract MyContract {-a1b2c3- string public name;-a1b2c3--a1b2c3- constructor(string memory _name) {-a1b2c3- name = _name;-a1b2c3- }-a1b2c3- }
scripts directory, for example, deploy.js:language="language-javascript"async function main() {-a1b2c3- const MyContract = await ethers.getContractFactory("MyContract");-a1b2c3- const myContract = await MyContract.deploy("Hello, Base Mainnet!");-a1b2c3- await myContract.deployed();-a1b2c3- console.log("MyContract deployed to:", myContract.address);-a1b2c3- }-a1b2c3--a1b2c3- main()-a1b2c3- .then(() => process.exit(0))-a1b2c3- .catch((error) => {-a1b2c3- console.error(error);-a1b2c3- process.exit(1);-a1b2c3- });
language="language-bash"npx hardhat run scripts/deploy.js --network base
This command will deploy your smart contract to the Base Mainnet, and you will see the contract address in the console output.
Verifying your smart contract on the Base Mainnet Explorer is crucial for transparency and trust. It allows users to see the source code and understand the contract's functionality. Here’s how to verify your contract:
language="language-bash"npm install --save-dev @nomiclabs/hardhat-etherscan
hardhat.config.js to include the Etherscan API key:language="language-javascript"module.exports = {-a1b2c3- // ... existing config-a1b2c3- etherscan: {-a1b2c3- apiKey: process.env.ETHERSCAN_API_KEY-a1b2c3- }-a1b2c3- };
verify.js:language="language-javascript"async function main() {-a1b2c3- const contractAddress = "your_contract_address";-a1b2c3- await hre.run("verify:verify", {-a1b2c3- address: contractAddress,-a1b2c3- constructorArguments: ["Hello, Base Mainnet!"],-a1b2c3- });-a1b2c3- }-a1b2c3--a1b2c3- main()-a1b2c3- .then(() => process.exit(0))-a1b2c3- .catch((error) => {-a1b2c3- console.error(error);-a1b2c3- process.exit(1);-a1b2c3- });
language="language-bash"npx hardhat run scripts/verify.js --network base
After running this command, your contract will be verified on the Base Mainnet Explorer, making it accessible for public viewing.

Monitoring and managing your deployed smart contract monitoring is crucial for ensuring its performance, security, and overall functionality. This involves using various tools and techniques to keep track of contract activity and to implement effective logging mechanisms.
Block explorers are essential tools for monitoring the activity of deployed smart contracts on blockchain networks. They provide a user-friendly interface to view transactions, contract interactions, and other relevant data. Here’s how to effectively use block explorers:
Using block explorers not only helps in tracking contract activity but also aids in identifying potential issues or irregularities in contract interactions. For instance, if you notice an unusually high number of failed transactions, it may indicate a bug or vulnerability in your contract.
Implementing logging and event emission in your smart contract is vital for effective monitoring and debugging. Events in Ethereum are a way to log information on the blockchain, which can be accessed by external applications and users. Here’s how to implement logging and event emission:
language="language-solidity"event Transfer(address indexed from, address indexed to, uint256 value);
language="language-solidity"function transfer(address to, uint256 value) public {-a1b2c3- // Logic for transferring tokens-a1b2c3- emit Transfer(msg.sender, to, value);-a1b2c3-}
By implementing logging and event emission, you can significantly enhance the tracking capabilities of your deployed contract monitoring. This not only aids in debugging but also provides transparency to users interacting with your contract.
