What We Built
OPN Builder Hub is a simple decentralized application that allows users to connect their wallet and interact with the HelloOPN smart contract deployed on the OPN network.
Why
I built this project to learn the complete OPN development workflow, including writing a Solidity smart contract, deploying it, verifying the source code, and hosting the frontend on Vercel. It is a beginner-friendly project that demonstrates the basics of Web3 development on OPN.
How It Works
- Open the OPN Builder Hub website.
- Click the Connect Wallet button.
- Connect your wallet.
- Interact with the HelloOPN smart contract.
- The frontend communicates with the deployed contract through the OPN network.
Tech Stack
- Solidity
- HTML
- CSS
- JavaScript
