FinCEN has withdrawn two proposed rules that would have tightened reporting requirements on unhosted crypto wallets and crypto mixers, the Treasury bureau confirmed. The move lands as part of the Trump Administration's broader deregulatory agenda. In pulling the mixer rule, the bureau pointed to concerns over 'legitimate activity' that the proposal could have swept up.
What the two rules would have done
The first proposal targeted unhosted wallets — self-custodied addresses that sit outside any exchange or custodian. The second dealt with crypto mixers, services that pool and shuffle coins to obscure their origin. Both had been floated under the prior administration as tools to close gaps in the existing anti-money-laundering regime.
Neither made it to a final rule. Now neither will.
FinCEN's stated reason for dropping the mixer proposal is notable: the bureau flagged that the rule as written risked catching 'legitimate activity' alongside the illicit flows it was meant to target. That's an unusual admission from a financial intelligence unit, and it gives the withdrawal a substantive rationale rather than a purely political one.
The deregulation context
The withdrawals aren't happening in a vacuum. They're being framed as part of the Trump Administration's deregulatory agenda, which has been reshaping how federal agencies approach digital assets since the administration took office.
For the crypto industry, the two rules were perennial complaint points. Exchanges and wallet developers argued that unhosted wallet reporting requirements would push users offshore and saddle software providers with compliance duties they weren't built to handle. Mixer rules drew similar pushback, with critics saying they conflated privacy tools with criminal infrastructure.
Now both are off the table. The practical effect is that no reporting regime for self-custodied wallets or mixer transactions is coming from FinCEN under this proposal cycle. Whether the bureau revisits the issue in a different form is an open question — the withdrawal kills these specific drafts, not the underlying policy authority.
What's still unsettled
Two things to watch. First, whether FinCEN signals any intent to draft narrower versions of either rule. The 'legitimate activity' language suggests the bureau sees a drafting problem, not a policy dead end. Second, whether other US regulators pick up where FinCEN left off — the Treasury bureau isn't the only agency with a stake in crypto AML enforcement.
For now, the immediate takeaway is simple: two proposed rules that had been hanging over the self-custody and mixer segments are gone, and the bureau's own reasoning leans on the risk of overreach rather than the absence of a problem.
