Short answer: On October 5, 2026, the U.S. Treasury's Financial Crimes Enforcement Network (FinCEN) withdrew two long-pending crypto proposals: a December 2020 rule that would have made banks and money services businesses record transfers above $3,000 to self-hosted wallets and report those above $10,000, and a 2023 plan to treat international crypto mixing as a "primary money laundering concern." Neither rule was ever finalized, so existing obligations do not change, but the two biggest surveillance threats to self-custody are now off the table.
What happened
On Monday, October 5, 2026, FinCEN posted two withdrawal notices to the Federal Register's public inspection site, with formal publication set for the next day. The mixing notice was signed by Deputy Director Jimmy L. Kirby.
- The self-hosted wallet proposal dates from December 2020, the final weeks of Donald Trump's first term. A self-hosted (or unhosted) wallet is one where you hold the keys yourself rather than leaving coins with an exchange. FinCEN wrote that it will take no further action on the proposal.
- The mixer proposal dates from October 2023 under the Biden administration. A mixer is a service that pools and reshuffles coins so the link between sender and receiver is hard to trace. The proposal relied on Section 311 of the USA PATRIOT Act, a power that had never before been used against a whole class of transactions.
The same day, the Commodity Futures Trading Commission (CFTC) began a separate rulemaking, Regulation CTX and Regulation CAM, that would create a federal path for exchanges to offer leveraged and margined spot crypto trading to retail customers.
What the two withdrawn rules would have required
| Proposal | Proposed | Main requirement | Status now |
|---|---|---|---|
| Self-hosted wallet rule | December 2020 | Banks and money services businesses verify identities and keep records for transfers above $3,000 to or from unhosted wallets; report transfers above $10,000, including several that add up to more than $10,000 within 24 hours | Withdrawn; no further action |
| Mixer rule (Section 311) | October 2023 | Report transactions linked to international mixing, with wallet addresses, transaction hashes and IP addresses; no dollar threshold | Withdrawn; FinCEN keeps monitoring |
The mixer rule defined "mixing" very widely. Pooling funds, splitting a payment into pieces, using single-use wallets or adding deliberate delays could all have counted. Coinbase warned in a January 2024 comment letter that the lack of a threshold would force bulk reporting of ordinary, non-suspicious transfers.
Why Treasury changed course
FinCEN gave two main reasons. First, commenters argued that the mixing definition was so broad it could chill legitimate activity and impose a heavy reporting load. Second, both notices cite the July 2025 report of the President's Working Group on Digital Asset Markets, which backed the right of lawful users to transact privately on public blockchains. FinCEN described the wallet withdrawal as part of keeping digital asset rules "fit for purpose."
The agency did not say mixers are harmless. It still believes criminals use them to hide money trails and said it may act again in the future. Coin Center, the Washington policy group that opposed both proposals, welcomed the move; its executive director Peter Van Valkenburgh called it a bright spot in a difficult month for privacy, while warning that the legal authority to write similar rules still exists.
The decision fits a wider pattern. Treasury removed Tornado Cash from its sanctions list in March 2025 after an appeals court found that sanctions regulators had overstepped, and a March 2026 Treasury report to Congress acknowledged that mixers have legitimate privacy uses.
What it means for you
Day to day, nothing changes overnight, because neither rule was in force. The practical points:
- Self-custody stays unburdened. Moving coins from an exchange or exchanger to your own wallet will not trigger a new U.S. federal record-keeping rule at the $3,000 or $10,000 level.
- Existing checks still apply. Regulated platforms keep their current anti-money-laundering duties, and any service can still ask about the source of funds or block coins linked to sanctioned addresses.
- Mixed coins can still be flagged. Withdrawing a proposal is not an endorsement. Blockchain analytics firms and compliance teams continue to score coins that passed through mixers, which can delay a swap or a deposit.
- The door is not locked. FinCEN kept the power to propose similar rules later, so a future administration could revisit them.
Key takeaways
- FinCEN withdrew its December 2020 self-hosted wallet proposal and its October 2023 mixer proposal on October 5, 2026.
- The wallet rule would have required records above $3,000 and reports above $10,000.
- Neither rule was finalized, so current obligations for financial institutions are unchanged.
- FinCEN says it will keep watching mixers and could act again.

Frequently asked questions
Did FinCEN cancel the self-hosted wallet rule?
Yes. On October 5, 2026, FinCEN withdrew the December 2020 proposal that would have required record-keeping for transfers above $3,000 involving self-hosted wallets and reporting above $10,000, and said it will take no further action on it.
Are crypto mixers legal in the US now?
The withdrawal only ends a 2023 plan to add special reporting rules for international mixing. It does not legalize laundering, sanctions still apply, and FinCEN said it may take action on mixers again in the future.
Does the FinCEN withdrawal change KYC on exchanges?
No. Neither proposal was ever finalized, so exchanges and other regulated services keep their existing identity checks and anti-money-laundering obligations.
