What the builder said.
Written by the team, rendered as the markdown they typed in the submission wizard.
What we built
We built a simple Web3 Counter dApp deployed on the OPN chain. It allows users to connect their wallet and interact with a smart contract to increment and decrement a global on-chain counter. Every action is recorded on-chain, making the state fully transparent and permissionless.
Why
We built this project to demonstrate the basics of decentralized application development, including smart contract deployment, blockchain interaction, and wallet integration. The goal was to show how traditional app logic (like a counter) can be moved on-chain without any centralized backend.
How it works
- A smart contract is deployed on the OPN chain that stores a single
countvariable - Users connect their wallet using MetaMask
- The frontend (hosted on Vercel) interacts with the contract using ethers.js
- Users can increment or decrement the counter
- Every update is written directly to the blockchain, ensuring transparency and immutability
Roadmap

What ships next.
The builder's own next-quarter plan. Use it to gauge follow-through and ambition.
Q1 · Current
- Deployed a simple Counter dApp on OPN chain
- Integrated smart contract with frontend using ethers.js
- Connected MetaMask wallet for on-chain interactions
- Hosted frontend on Vercel
Q2 · Next Upgrade
- Add proper UI/UX improvements (modern dashboard)
- Add transaction history view (on-chain events)
- Improve contract with access control and reset function
- Deploy upgraded version of smart contract
Q3 · Expansion
- Convert counter into token-based interaction system
- Add user leaderboard based on interactions
- Introduce rewards system for engagement
Beyond
- Evolve into a full DeFi interaction playground
- Support multiple contracts and modules
- Make it a reusable starter template for OPN ecosystem apps
On-chain proof
03/03
2 contracts on OPN Chain.
The chain itself confirmed every deployment is valid, signed by the builder's wallet, and inside the season's window.
