FinCEN Withdraws Proposed Crypto Wallet and Mixer Rules

The U.S. Financial Crimes Enforcement Network has formally withdrawn two proposed rulemaking actions that would have imposed new compliance requirements on cryptocurrency wallets and mixing services. The withdrawal removes pending regulatory pressure from two of the more contested crypto oversight proposals FinCEN had put forward, leaving the status of both policy areas unsettled.

FinCEN Pulls Back on Wallet and Mixer Oversight

FinCEN’s proposed wallet rule would have required banks and money services businesses to collect and verify identifying information for certain unhosted wallet transactions above a threshold amount, per CryptoPotato reporting. The mixer proposal separately targeted services that pool or obscure the origin of crypto transactions, which regulators have flagged as a vehicle for illicit finance. FinCEN had previously taken enforcement action against Russia-linked crypto networks handling billions in transactions, underscoring its broader focus on financial crime in the digital asset space.

Both proposals drew significant industry pushback during their comment periods, with critics arguing the requirements were technically unworkable and would expose compliant users to disproportionate surveillance. The withdrawal means neither proposal will advance to a final rule in its current form. The agency’s broader effort to restrict Iran’s access to cryptocurrency through other channels remains active.

Scope of the Withdrawn Proposals

Wallet-Related Rules

The wallet-related measure would have extended Bank Secrecy Act recordkeeping obligations to cover transfers involving self-custodied addresses, effectively treating unhosted wallets as counterparties subject to identity verification. This stood apart from existing rules, which apply primarily to transactions between regulated institutions.

Mixer-Related Rules

The mixer-related proposal sought to designate certain mixing activity as a primary money laundering concern under Section 311 of the USA PATRIOT Act. A Section 311 designation can restrict or prohibit U.S. financial institutions from processing transactions connected to the named activity, the same tool FinCEN has applied in actions targeting illicit crypto flows through Chinese laundering networks. Sanctions enforcement actions, such as the U.S. sanctions against entities involved in Hamas crypto financing, show the range of complementary tools that remain in place even after the withdrawals.

What the Withdrawal Leaves Open

Key Implications for Crypto Stakeholders

The withdrawal does not legalize mixing services or remove existing anti-money-laundering obligations from crypto businesses. Existing FinCEN guidance, Bank Secrecy Act requirements, and OFAC sanctions programs remain in effect. What remains genuinely uncertain is whether FinCEN intends to refile revised versions of either proposal or pursue the same objectives through alternative regulatory channels.

No replacement action has been announced. Rulemaking activity continues across federal agencies: the SEC recently disclosed an estimated $433,833 annual cost for its crypto custody fallback rule, a signal that detailed digital asset rulemaking continues even as specific FinCEN proposals are pulled back. Compliance teams and wallet providers should monitor the Federal Register for any successor notices before drawing conclusions about the long-term regulatory trajectory.
