When trading on C2C platforms like Karrot (Danggeun Market), there's no comprehensive standard for evaluating a counterparty's reputation score, payment trustworthiness, and transaction history, leading to fraud losses or abandoned safe transactions with an average opportunity cost of $37.50-$112.50 (~50,000-150,000 KRW) per transaction. For high-value items (electronics, luxury goods), using escrow adds 3-5% in fees, and researching a seller's profile takes 10-20 minutes per transaction.
The tool crawls public profiles across multiple C2C platforms (Karrot, Bunjang, Jungonara) — reputation scores, review keywords, repeat transaction rates — to calculate a unified trust score. Users enter a counterparty's profile URL before a transaction to receive fraud risk assessment and recommended transaction method (in-person/shipping/escrow). Suspicious patterns (new account with high-value listings, duplicate photos, etc.) are auto-detected with alerts.
