Smart Contract Deployment

Buburuza supports Solidity and Vyper contracts using standard Ethereum tools.

Example: Deploying Your First dApp with Hardhat

1. Initialize Hardhat:

mkdir my-buburuza-dapp && cd my-buburuza-dapp
npm init -y
npm install --save-dev hardhat
npx hardhat

1. Configure Hardhat for Buburuza Testnet:

module.exports = {
  networks: {
    buburuzaTestnet: {
      url: "https://rpc.buburuza.com",
      chainId: <TESTNET_CHAIN_ID_DECIMAL>,
      accounts: [process.env.PRIVATE_KEY]
    }
  },
  solidity: "0.8.20"
};

1. Deploy a simple contract (Greeter.sol):

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.20;

contract Greeter {
    string public greeting;

    constructor(string memory _greeting) {
        greeting = _greeting;
    }

    function greet() public view returns (string memory) {
        return greeting;
    }
}

1. Deploy using Hardhat script (deploy.js):

async function main() {
  const Greeter = await ethers.getContractFactory("Greeter");
  const greeter = await Greeter.deploy("Hello, Buburuza!");
  await greeter.deployed();
  console.log("Greeter deployed to:", greeter.address);
}
main();

1. Verify deployment on Buburuza Explorer.
