Add wallet connect & on-chain certification to desktop app
Hey, I have a desktop app already built (Electron + React) that helps people make decisions using AI. The app works fine, I just want to add a blockchain feature to it. Basically I want users to be able to certify their decisions on Polygon, so after the AI gives results, they can hit a button, connect their MetaMask wallet, and store a hash of that decision on-chain. Then later anyone can verify it's real and unchanged. Here's what I need: - MetaMask connect/disconnect in the app (it's a desktop Electron app, not a browser) - A simple Solidity contract on Polygon that stores the hash + wallet + timestamp - A "Certify" button on the results page - A verification page where you paste a hash and confirm it's legit - A small "Certified" badge on saved decisions with a Polygonscan link Budget is around $5,000–$8,000. I'd prefer fixed price. Timeline around 3 weeks. If you've done Polygon smart contracts and worked with Electron before, please message directly. Thanks Apply tot his job Apply To this Job
