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.
Case study · the one that started it
m2mcent.com — 965 endpoints, two rotations in 7 days
Their directory listing advertised wallet 0xb049…20ec. Live probes caught payments being served to 0xdb48…4a74 on day 3 — then 0x5d47…4efa by day 7. The listing never changed.
3,858 of 6,755 probes mismatched in the window. Any agent paying those doors was sending USDC to an address the seller never published.
Counts dated to the 2026-08-23 drift report (ops/metrics/payto_drift_2026-08-23.json) — kept as the narrative demo. Live index numbers refresh from /v0/stats (see band above).
