Bitcoin Sanctions Risk

The Bitcoin-specific sanctions surface: designated addresses, mixer exposure, and the screen-before-sign step.

Overview

Bitcoin is a sanctioned-asset surface like any other — OFAC designates Bitcoin addresses and pursues mixer and exchange exposure. Screening a BTC destination is the same obligation as screening an EVM wallet.

What is designated

OFAC lists Bitcoin addresses on the SDN list alongside EVM and Tron addresses. The SanctionsAI dataset covers 947 OFAC wallets across EVM, Bitcoin, and Tron, synced hourly.

Mixer and taint exposure

Designated mixers (e.g., Blender, Sinbad) create exposure for downstream recipients. Screening the immediate counterparty is necessary but not sufficient; taint-aware review matters for high-value flows.

The builder action

Add a BTC address screen before every outgoing transaction — the same single call as EVM screening. The wallet checker supports it for free.
