FinCEN, the Treasury Department's financial intelligence unit, has withdrawn two proposed rules that hung over self-custody and crypto mixers for years. Neither ever took effect. For people who hold their own keys, it ends a threat that had existed since December 2020.
What exactly was scrapped?
The agency filed the withdrawal notices on Monday, October 5, and they are due to appear in the Federal Register on Tuesday. On the wallet proposal it wrote only: "FinCEN will take no further action on this NPRM." According to CoinDesk, the agency tied the move to the Trump administration's deregulatory agenda and its push for "fit-for-purpose" digital-asset rules.
Two initiatives from different years went at once. The first, from 2020, covered so-called unhosted wallets, meaning wallets a user controls without an exchange or bank. The second, from 2023, would have branded international crypto mixing as a primary money laundering concern.
How would the wallet rule have worked?
The proposal landed in the final weeks of Donald Trump's first term. It carried the logic of the Bank Secrecy Act, which already governs ordinary bank transfers, over to personal wallets.
- Records from $3,000: banks and money transfer services would have kept data on a customer's transactions with their own wallet above that threshold.
- A report to the regulator would be mandatory from $10,000, including counterparty details.
- Large crypto exchanges and any other service that sends funds to a private address would have been covered.
- A user withdrawing Bitcoin to their own Ledger or Trezor would have been under watch before the first transaction.
The industry called it an attempt to treat everyone who holds their own keys as a suspect by default.
Why mixers were in the crosshairs
Mixers pool coins from many users to break the visible chain between sender and recipient. Law enforcement sees a laundering tool, while privacy advocates point out that ordinary people also use such services because they do not want the whole world reading their balance.
The 2023 proposal would have named international crypto mixing a "primary money laundering concern" under the USA PATRIOT Act. Financial institutions would have had to pass along wallet addresses, transaction hashes and even IP addresses tied to suspected mixing.
The agency admitted that commenters had warned the definition of mixing was too broad. Such wording could catch perfectly legal activity. FinCEN added that it will keep watching mixers and may act again later.
Why it is too early to celebrate
Coin Center, the Washington group that fought both proposals for years, greeted the news with restrained joy. Executive director Peter Van Valkenburgh wrote on X that it had been a hard month for privacy, but there was a bright spot.
"The underlying statutory authority to create new, similar bad rules remains."

So the withdrawal does not close the topic for good. Another administration or another agency head could return to the idea in a new form. A separate argument over self-custody is also running at other regulators, such as the Consumer Financial Protection Bureau.
What changes for wallet owners
Right now, nothing, and that is the point: the rules never applied, so market behavior stays the same. What disappears is the shadow that made it hard for exchanges and wallet makers to plan self-custody products.
For anyone who keeps Bitcoin on hardware devices, the main takeaway is simple: withdrawing to your own address stays an ordinary operation with no extra reporting. To pick a device, browse the catalog of hardware wallets. Exchanges still check customers under existing KYC requirements.
