Trade Shield
AI-powered payment verification that helps you trade with confidence. Upload a payment screenshot and get instant analysis β amount matching, timestamp validation, and manipulation detection. Your documents never leave your device on the free tier.
How Trade Shield Fits Your Trade
Trade Shield integrates directly into the trade flow. When a buyer sends payment proof, Trade Shield analyzes it and generates a confidence checklist β a series of verification checks that help the seller decide whether to release escrow.
Buyer uploads payment proof
A screenshot, photo, or PDF of the payment confirmation from their bank or payment service.
Trade Shield analyzes the document
AI checks the amount, date, payment method consistency, and image authenticity. On the free tier, this happens entirely in your browser.
Confidence checklist is generated
Each check is marked pass, warn, or fail. The seller sees the checklist alongside the payment proof and decides whether to release escrow.
Seller releases with confidence
Trade Shield advises, never decides. The seller always has the final say on releasing escrow.
The Confidence Checklist
Every payment analysis generates a checklist tailored to the payment method. Each item is independently verified and clearly marked.
Example: Bank Transfer Payment
Confidence: 4 of 5 checks passed
