Building Your First dApp on Ramestta
Ready to build on Ramestta? This comprehensive tutorial will guide you through deploying your first decentralized application on our Layer 3 network.
Prerequisites
Before we begin, make sure you have:
Step 1: Set Up Your Development Environment
Install Hardhat
npm install --save-dev hardhat
npx hardhat init
Configure Ramestta Network
Add Ramestta to your `hardhat.config.js`:
module.exports = {
networks: {
ramestta: {
url: "https://blockchain.ramestta.com",
chainId: 1370,
accounts: [process.env.PRIVATE_KEY]
}
},
solidity: "0.8.20"
};
Step 2: Write Your Smart Contract
Create a simple token contract:
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.20;
import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
contract MyToken is ERC20 {
constructor() ERC20("MyToken", "MTK") {
_mint(msg.sender, 1000000 * 10 ** decimals());
}
}
Step 3: Compile Your Contract
npx hardhat compile
Step 4: Deploy to Ramestta
Create a deployment script:
async function main() {
const MyToken = await ethers.getContractFactory("MyToken");
const token = await MyToken.deploy();
await token.deployed();
console.log("Token deployed to:", token.address);
}
main()
.then(() => process.exit(0))
.catch((error) => {
console.error(error);
process.exit(1);
});
Deploy:
npx hardhat run scripts/deploy.js --network ramestta
Step 5: Build Your Frontend
Create a React frontend to interact with your contract:
import { ethers } from 'ethers';
const connectWallet = async () => {
const provider = new ethers.providers.Web3Provider(window.ethereum);
await provider.send("eth_requestAccounts", []);
const signer = provider.getSigner();
return signer;
};
const getTokenBalance = async (tokenAddress, userAddress) => {
const signer = await connectWallet();
const tokenContract = new ethers.Contract(
tokenAddress,
['function balanceOf(address) view returns (uint256)'],
signer
);
const balance = await tokenContract.balanceOf(userAddress);
return ethers.utils.formatEther(balance);
};
Step 6: Test Your dApp
1. Add Ramestta network to MetaMask
2. Get test tokens from the faucet
3. Connect your wallet
4. Test contract interactions
