Onchain Risk Note

Understanding wallet behavior beyond simple blacklists

This note focuses on behavior-first risk signals: transaction cadence, routing irregularity, gas usage, service affinity, and liquidation timing. The goal is earlier detection before formal list placement.

February 2026
Summary

An analysis of behavioral heuristics that reveal high-risk wallets before they are officially designated by OFAC or added to commercial blacklists.

Key findings
  • Behavioral anomaly scoring can surface suspicious wallets well before sanctions or takedown events.

  • Repeated use of the same routing pattern across fresh addresses is a strong clustering signal.

  • Context matters: the same behavior can mean market making, treasury ops, or obfuscation depending on counterparties.

Operational use
  • Strengthen source-of-funds screening for high-value inbound wallets.
  • Tune monitoring rules for early warning signals on watchlisted entities.
  • Improve analyst escalation notes for false-positive review.
