Full-Stack DApp Developer Needed
Budget: €18 – €36 EUR
I’m building ArbMarket, a prediction-market platform that mirrors the user experience of Polymarket while running on Arbitrum. The contracts (written in Solidity) are already live on testnet, so the project sits firmly in mid-development; what remains is tying everything together into a production-ready, full-service dApp.
Here’s what I still need:
• Frontend: A responsive interface that displays markets, handles wallet connections, and guides users through trading and liquidity actions.
• Backend: Lightweight APIs, database hooks, and any off-chain services (price resolution, event schedulers) necessary for a seamless market UX.
• Web3 integration: Robust ethers/web3 hooks that talk to our deployed Solidity contracts on Arbitrum, covering transactions, event listening, and analytics.
You’ll have plenty of freedom to pick the stack for the web layers—React and Node are natural fits but I’m open if you can justify another approach—yet deep EVM knowledge is non-negotiable. Prior experience with prediction markets, order books, or Layer-2 rollups will stand out.
Acceptance criteria will revolve around:
1. Users signing and sending trades end-to-end on Arbitrum without console errors.
2. Market data loading sub-second from both on-chain and backend sources.
3. Clean, documented code that my small team can maintain after hand-off.
If you can jump in quickly, communicate clearly, and turn partially built components into a polished, launch-ready product, let’s talk code and timelines.
