Seller Monitoring
Your listing says one wallet. Your live endpoint answers with another. Your buyers — human or agent — have no way to know. We watch who actually receives the money, every day, and flag the rotation the moment it happens.
What you get
- Weekly payTo-drift report — every endpoint you run: advertised wallet vs live 402 requirements, side by side, dated.
- Rotation alerts — flagged the day our probes see your live payTo diverge from your listing. Not weekly. The day it happens.
- Badge you can earn: stable-wallet-30d — one wallet, unchanged ≥30 days, listing agrees with live responses. Verified by our probes, not self-declared.
- History — dated snapshot trail for every finding. Every claim traces to pipeline evidence.
