What we built OPN Builder Board is a decentralized reputation and badge system built on OPN Chain. Builders connect their wallet, get their badge automatically calculated from their real onchain transaction count, and claim it permanently onchain also you submit the project you built on IOPN. WHY There was no easy way for OPN Chain builders to prove their on-chain activity or earn a verifiable credential based on real contributions. OPN Builder Board solves this by making builder reputation transparent, on-chain, and claimable by anyone. How it works
Connect your wallet to OPN Testnet Click Check My Score the dApp reads your real transaction count directly from the OPN Chain RPC Your badge is calculated automatically: Gold, Silver, Bronze, Newbie. Click Claim Badge writes your badge on-chain, creating a real OPN transaction Builders can also register a full profile with a public pledge of what they are building on OPN Chain A live leaderboard ranks all builders and claimants by score A public Pledge Board shows every builder's commitment to the ecosystem
Tech stack
Solidity smart contract deployed on OPN Chain Testnet (Chain ID: 984) Pure HTML/JS frontend with no frameworks and backend ethers.js v6 for wallet connection and contract interaction eth_getTransactionCount via OPN RPC for automatic TX-based scoring Deployed on GitHub Pages / Vercel.
