Ethereum Web3 Full-Stack Integration

I’m building a product that needs seamless blockchain integration from the smart-contract layer all the way to the user interface, and I’m looking for a full-stack engineer who is comfortable owning that journey end-to-end on Ethereum.

The core task is to wire up our existing web application to Ethereum mainnet and, where appropriate, test networks. That means designing or refining Solidity contracts, setting up a robust backend service (Node.js or comparable) that talks to the chain via Ethers.js or Web3.js, and delivering a clean, responsive frontend—React is our default stack—that exposes all contract functions without compromising UX or security.

If you’ve previously deployed contracts with Hardhat or Truffle, handled events in real time, and can orchestrate CI/CD pipelines for smart-contract deployments, you’ll feel right at home here. Your proposal should outline the architecture you prefer, any libraries you’d lean on, and a suggested timeline with milestones from contract audit through production deployment and post-launch monitoring.

I’ll review submissions that include a detailed project proposal explaining how you intend to tackle the integration, the tools you plan to use, and any potential risks or edge cases you foresee. Links to public repositories or live dApps demonstrating similar work are welcome but optional—the proposal itself is the priority.

Once we align on approach, the deliverable is a fully functional, tested, and documented Ethereum integration ready for production release.
