How OFAC enforcement has evolved for crypto 2018-2026

OFAC enforcement has expanded from designating a few crypto addresses to treating digital assets as a routine part of the sanctions regime.

TL;DR

TL;DR: Crypto is now firmly inside OFAC's sanctions scope, with wallet addresses on the SDN List and enforcement applied under the same strict liability standard as traditional finance.

Early designations

OFAC began adding crypto wallet addresses to the Specially Designated Nationals and Blocked Persons List, signaling that on-chain activity is not outside its reach. Over time, the list has grown to 947 OFAC-listed crypto wallets tracked by SanctionsAI, alongside 19,218 SDN names.

A broader enforcement framework

Enforcement now treats crypto like any other financial channel. Strict liability still applies, meaning intent is not required for a violation, and civil penalties start at $356,000 per violation. The 50 Percent Rule extends exposure to entities 50 percent or more owned by a blocked person.

What it means today

The practical result is that anyone moving value on-chain, including AI agents, must screen counterparties before paying. Payment rails like x402, AP2, ACP, and Coinbase AgentKit move money but do not screen it. Screening APIs like SanctionsAI close that gap with one HTTP call under 100 ms.
