I spent 3 years as an import-export broker watching the same fraud repeat itself. A buyer wires money to a supplier. The supplier disappears. The bank says irreversible. Courts can't cross international borders fast enough to matter. $17 billion disappears from traders this way every year. Not hackers. Just broken infrastructure. The obvious fix: escrow. But the existing options — Letters of Credit — cost $500-2000 to open, take 5 days, and still leave gaps. So I built Fintdex. Smart contract on Polygon. USDT locks until both parties confirm delivery. Our AI verifies the Bill of Lading in 8 seconds (carrier records, port logs, cargo weight, fraud pattern matching). Both parties track the shipment live. Delivery confirmed — funds release in 3 seconds. 0.5% fee. Contract is public on Polygonscan — technical folks can read every line: https://polygonscan.com/address/... I'm a solo founder, 21, built this alone with no funding from India. Ranked #44 on CodeHawks smart contract security (41 findings, 20 High severity). Looking for: feedback on the approach, anyone doing international trade in USDT who wants to test a transaction, and anyone who thinks this is technically wrong — I want to know. Happy to answer everything.
