FinCEN withdrew its 2020 unhosted-wallet and 2023 mixer proposals. Neither was ever a rule

The Treasury Department's financial crimes unit, FinCEN, formally withdrew two long-pending crypto proposals this month. Notices were posted to the Federal Register's public inspection site on Monday, October 5, 2026, with formal publication set for October 6, according to The Block, which links the documents as 2026-20429 (mixing) and 2026-20430 (self-hosted wallets).

What was actually withdrawn

• The 2023 mixing proposal. FinCEN dropped its finding that international crypto mixing is a "class of transactions of primary money laundering concern" under Section 311 of the USA PATRIOT Act, plus the reporting rule attached to it. That rule would have required reports covering wallet addresses, transaction hashes and IP addresses.
• The December 2020 self-hosted wallet proposal. It would have made banks and money services businesses verify customers and keep records on transfers involving unhosted wallets, with a $3,000 recordkeeping threshold and a $10,000 reporting threshold.

The part the headlines skip

Neither proposal was ever finalized. Withdrawing them therefore does not alter what exchanges and banks must do today. The compliance regime that applies to crypto businesses is the same on October 17 as it was on October 4.

FinCEN's stated reasons differ. On mixing, it said commenters warned that the broad definition of mixing could chill legitimate activity and burden covered institutions. It also said it still believes illicit actors use mixers and "will continue to monitor" them, so a future action is possible. On self-hosted wallets, it said it "will not take any further action" on the proposal, as part of efforts to make digital asset rules fit for purpose. Both notices cite the July 2025 report of the President's Working Group on Digital Asset Markets.

Why it matters, and what it does not

For anyone holding bitcoin in their own wallet, the practical change is the removal of an overhang: a rule that could have forced exchanges to log or report withdrawals to self-custody addresses will not arrive in that form. For businesses that accept or pay in crypto, nothing about their day-to-day obligations moves.

It also does not settle market structure. The CLARITY Act is still stalled in the Senate, as we covered in CLARITY Act stalls, and a withdrawn proposal can be re-proposed by a future administration.

Where the video went further than the record

A popular crypto video this week described the Treasury as "withdrawing" both rules and added that the SEC and CFTC are "charging ahead with very good new rules." The withdrawals check out against the Federal Register notices. The second claim is a characterization, not a fact we verified in this report.
