What they built

SentryFlow

SentryFlow is an intelligent return fraud detection engine built on NitroStack by team Peers of Posts (SRMIST) to eliminate "empty-box" return scams on e-commerce platforms like Amazon Seller Central. The second a return package is scanned, SentryFlow analyzes weight discrepancies against catalog specs, computes an explainable fraud score, and gates high-value payouts for human review. Every decision is cryptographically locked in an append-only SHA-256 audit trail and high-risk cases automatically trigger pre-formatted Safe-T claim dispute emails via Resend, protecting seller revenue before refunds are cleared.
