The Strict Liability Standard

Unlike criminal statutes that require willful intent, OFAC civil enforcement operates under strict liability: a U.S. individual, corporate relayer, or validator can be penalized for facilitating a transaction with a designated wallet even if they had zero actual knowledge of the illicit nexus.

02

MEV-Boost Relayer Filtering & Neutrality

To avoid civil penalties, prominent block builders and MEV-Boost relays initially filtered out transactions referencing sanctioned addresses. This spurred intense protocol engineering to protect censorship resistance, including proposer-builder separation (PBS) and inclusion lists.

Frequently
Asked Questions.

SDN List compliance, smart contract litigation, and strict civil liability.

Visit our comprehensive FAQ hub
01

What is OFAC's SDN List in the context of digital assets?

The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) maintains the Specially Designated Nationals (SDN) List. OFAC designates illicit actors, mixing services, cyber syndicates, and specific blockchain wallet addresses (e.g., Bitcoin, Ethereum, Tron), prohibiting U.S. persons from engaging in transactions with them.

02

How do sanctions affect DeFi protocols and RPC node operators?

While smart contracts execute autonomously on public blockchains, frontend interfaces, wallet providers, and centralized RPC infrastructure services (such as Infura and Alchemy) geoblock restricted jurisdictions and screen transaction origination addresses against OFAC API databases to comply with federal sanctions regulations.

03

Are blockchain validators and block builders legally liable for including OFAC-sanctioned transactions?

Under OFAC's strict-liability regime, processing transactions involving sanctioned addresses creates legal exposure for U.S. persons. Consequently, many major block builders and MEV-Boost relays (such as Flashbots) implement transaction filtering at the relay layer, igniting deep community debates around protocol censorship resistance and Ethereum neutrality.

04

Can an autonomous smart contract without a corporate owner be lawfully added to the SDN List?

This constitutional and administrative question has been actively litigated in federal courts following OFAC's designation of Tornado Cash immutable smart contracts. Federal appellate challenges argue that Section 203 of the International Emergency Economic Powers Act (IEEPA) only permits sanctioning 'property' owned by a foreign 'person' or 'national', whereas immutable decentralized code lacks human ownership.

05

How does an individual or firm petition for delisting or unfreezing erroneously tagged crypto addresses?

Parties mistakenly designated or suffering secondary contamination can file an administrative petition for delisting under 31 C.F.R. ยง 501.807 with OFAC's Compliance and Enforcement division, submitting cryptographic wallet audit records, on-chain provenance telemetry, and identity verification proofs demonstrating lack of illicit nexus.
