AidLedger | Transparent Aid Funding on Polygon | Hackathon Demo

What happens after an aid donation? AidLedger makes funding accountable through milestone-based escrow, evidence submission, and verifier approval. Donations stay in a smart contract until an approved milestone is released to the campaign’s designated recipient. This demo presents AidLedger’s campaign workflow on the Polygon Amoy testnet, with an on-chain history of contributions, evidence records, review decisions, and payouts. Key features: • Smart contract escrow with sequential milestone payouts • Separate organizer, donor, recipient, and verifier roles • Evidence fingerprints linked to on-chain records • Wallet-signed transactions through MetaMask • Saved transaction requests and recovery support Try AidLedger: https://aidledge-lemon.vercel.app/ Source code: https://github.com/pmman-sudo/aidledger Deployed smart contract: https://amoy.polygonscan.com/address/0xe1B... Built by Paul Iyen for 3rd-Web-Hack. Technology: Solidity, Polygon Amoy, Next.js, TypeScript, Node.js, PostgreSQL, ethers.js, MetaMask, Vercel, and Northflank. This is a testnet prototype using test POL with no monetary value. Campaign details and evidence are illustrative. Blockchain records provide an audit trail; they do not independently prove that real-world aid was delivered.
