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.

1

Buyer uploads payment proof

A screenshot, photo, or PDF of the payment confirmation from their bank or payment service.

2

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.

3

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.

4

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

βœ“ Amount matches trade β€” $510.00 USD
βœ“ Date is within payment window β€” May 25, 2026
βœ“ Payment method matches β€” Bank Transfer
βœ“ No image manipulation detected
! Sender name not verified β€” manual check recommended

Confidence: 4 of 5 checks passed

Privacy Architecture

Trade Shield is designed to respect LocalUSDT's privacy-first principles. Here's exactly what happens with your data at each tier.

Basic (Local AI)

  • β€’ AI model (ONNX) is downloaded once and cached in your browser
  • β€’ Images are processed entirely in your browser using WebAssembly
  • β€’ No data is sent to any server β€” not even LocalUSDT's
  • β€’ Analysis results stay on your device unless you share them in trade chat
  • β€’ Model size: ~50MB (downloaded once, cached indefinitely)

Advanced (Cloud AI)

  • β€’ You explicitly choose "Run Advanced Analysis" for each document
  • β€’ Image is encrypted in transit (TLS) and sent to a secure processing endpoint
  • β€’ Analysis runs in an isolated container with no persistent storage
  • β€’ Image and results are permanently deleted within 60 seconds of completion
  • β€’ No training β€” your data is never used to train any AI model
  • β€’ Audit log records that an analysis was performed, but not the content
