Jara Marketplace
Jara pays communities for hyper-local work. Businesses post micro-tasks — retail audits, price monitoring, inventory checks — and community earners complete them for small USDC rewards on Arc, locking pool funds from MetaMask and releasing payouts on approval. The client in app.js implements a multi-format verification system: photo proof with drag-and-drop previews, GPS check-ins with 100m proximity matching, and inventory worksheets that auto-compute stock variances. Tasks persist through an Express and Postgres API in api/index.js, and lib/arc-utils.js supplies reusable primitives like encodeERC20Transfer for raw ERC-20 payloads. The vanilla-JS frontend in index.html keeps the whole flow lightweight and low-bandwidth.
