FinCEN Withdraws Crypto Mixer and Unhosted Wallet Proposals

The Financial Crimes Enforcement Network (FinCEN) has withdrawn two long-standing crypto-related proposals, marking a rare retreat in U.S. crypto regulation. On October 5, FinCEN announced it was pulling back a 2020 proposal targeting transactions involving unhosted wallets and a 2023 proposal focused on crypto mixers. Neither proposal had been finalized, but both had shaped discussions around privacy, self-custody, and transaction monitoring in the crypto industry.

The first proposal would have required banks and money-service businesses to impose recordkeeping, identity-verification, and reporting requirements for transactions involving unhosted wallets. The second proposal aimed to treat international crypto mixing as a primary money-laundering concern, requiring additional reporting for transactions believed to involve mixing. FinCEN cited public comments that raised concerns about the proposals' breadth and potential impact on legitimate activities.

FinCEN's decision does not eliminate existing anti-money-laundering obligations for regulated financial institutions. Instead, it creates room for a more targeted regulatory approach. The move highlights the complexity of regulating self-custody and privacy tools in crypto, where users control their own keys and transaction histories are publicly visible. The agency emphasized that it is reconsidering how best to address illicit-finance risks without stifling innovation.

For crypto companies, the withdrawal presents a communications challenge. It is essential to distinguish between a withdrawn proposal and deregulation, as existing compliance requirements remain in place. The industry should focus on explaining the practical implications for roadmaps, customer verification, and transaction monitoring, rather than oversimplifying the policy shift.
