Problem

When trot fans aged 40-60 trade unofficial merchandise, fan meeting tickets, and support wreaths via KakaoTalk and Daum Cafe, prepayment scams (pay first, seller disappears) are rampant. This age group is largely unfamiliar with escrow payment concepts, with over 70% using direct bank transfers. Average fraud loss per incident is $37–$112, too small to justify a police report, so most victims simply give up.

Solution

Offer escrow payments for fan-to-fan transactions via a KakaoTalk mini-app. Features include seller verification (mobile identity confirmation), automatic settlement upon delivery confirmation, and automatic refunds for disputes. Pasting a fan cafe URL auto-generates a secure payment link for that transaction.

Target: Trot/Mr. Trot fan community members aged 40-60, participating in 1-5 unofficial merchandise trades per month
Revenue Model: 3.5% transaction fee (seller-paid), Monthly Subscription pass $1.40/month (reduced 2.0% fee), ad banner revenue
Ecosystem Role: Regulation
MVP Estimate: 2_weeks
