The U.S. Financial Crimes Enforcement Network, or FinCEN, has formally withdrawn two long-running crypto regulatory proposals: a 2020 rulemaking on certain transactions involving unhosted or self-hosted wallets and a 2023 proposal targeting international convertible virtual currency (CVC) mixing.
The withdrawals became effective on October 6, 2026, when the notices were published in the Federal Register. FinCEN had announced the decision a day earlier. The agency said it was withdrawing both proposals after reviewing the regulatory approach to digital assets and, in the case of the mixing proposal, concerns that an expansive definition could chill legitimate activity and impose substantial reporting burdens.
The most important distinction is this: neither proposal had become a final rule. Their withdrawal therefore removes proposed future requirements; it does not erase the Bank Secrecy Act, existing anti-money-laundering obligations, sanctions rules or other compliance duties that already apply to regulated financial institutions.

| Question | Short answer |
|---|---|
| What did FinCEN withdraw? | A 2020 proposal covering certain transactions involving unhosted/self-hosted wallets and a 2023 proposal covering international CVC mixing. |
| When did the withdrawals take effect? | October 6, 2026. |
| Was either proposal already law? | No. Both were proposed rulemakings, not final rules. |
| Does this end KYC or AML rules for crypto exchanges? | No. Existing Bank Secrecy Act and other applicable compliance obligations remain. |
| Does this make self-custody illegal or legal? | Self-custody was not banned by these proposals. The withdrawal removes a proposed reporting and recordkeeping framework around certain transactions involving self-hosted wallets. |
| Does FinCEN now approve crypto mixers? | No. FinCEN says illicit actors still use mixers and that it will continue monitoring mixing activity. |
| Does this affect Bitcoin or Ethereum themselves? | No. The withdrawals concern regulatory obligations around financial institutions and transaction activity, not the underlying protocols. |
| Is this relevant to DeFi? | Indirectly. It reduces the risk of these specific proposed rules being applied broadly, but it is not a comprehensive DeFi exemption. |
What happened on October 6, 2026?
FinCEN's official announcement confirmed that the agency was withdrawing two proposed digital-asset rules.
The first was the 2020 unhosted wallet proposal, formally titled Requirements for Certain Transactions Involving Convertible Virtual Currency or Digital Assets. The second was the 2023 CVC mixing proposal, which sought to use Section 311 of the USA PATRIOT Act to treat international CVC mixing as a class of transactions of primary money laundering concern.
The Federal Register notices made the withdrawals effective on October 6, 2026:
- FR Doc. 2026-20430 / 91 FR 63514 — withdrawal of the self-hosted wallet proposal.
- FR Doc. 2026-20429 / 91 FR 63513 — withdrawal of the CVC mixing finding and proposed special measure.
FinCEN said it will take no further action on the 2020 unhosted wallet NPRM. For mixers, the agency was more qualified: it withdrew the 2023 finding and proposal but said it will continue to monitor mixing activity for money laundering, terrorist financing and other illicit-finance risks.
What was the 2020 self-hosted wallet proposal?
The 2020 proposal focused on transactions involving unhosted wallets, commonly called self-hosted or self-custody wallets, and certain wallets hosted at foreign financial institutions not subject to the U.S. Bank Secrecy Act.
A self-hosted wallet is a wallet in which the user controls the keys rather than relying on a regulated intermediary to custody the assets.
The proposed rule would have imposed additional requirements on banks and money services businesses (MSBs) when their customers transacted with certain unhosted or otherwise covered wallets.
What would the proposal have required?
According to the Federal Register withdrawal notice, the proposal would have required banks and MSBs to:
- file reports with FinCEN for certain transactions greater than $10,000, including multiple covered transactions aggregating above $10,000 within 24 hours;
- retain records for certain covered transactions greater than $3,000;
- verify the identity of their own customer;
- collect specified information related to the transaction and counterparty.
The proposal was never finalized.
That distinction matters because users sometimes describe the 2020 proposal as if a special "$3,000 self-hosted wallet rule" or "$10,000 wallet reporting rule" had already been in force. It had not.
What was the 2023 crypto mixer proposal?
In October 2023, FinCEN proposed a much broader regulatory action involving convertible virtual currency mixing.
The agency made a finding under Section 311 of the USA PATRIOT Act that international CVC mixing was a class of transactions of primary money laundering concern and proposed a special measure requiring covered financial institutions to perform enhanced recordkeeping and reporting.
The proposal was notable because it targeted a class of transactions, rather than only a particular financial institution or jurisdiction.
Its definition of mixing was broad enough to include multiple methods used to make blockchain transaction flows harder to trace, such as pooling assets, splitting transactions and other techniques that can obscure the source, destination or amount of funds.
Why did FinCEN withdraw the mixer proposal?
The Federal Register withdrawal says FinCEN continues to believe that illicit actors use mixers and other tools to frustrate law-enforcement investigations.
But the agency also acknowledged concerns raised by commenters that the proposal's expansive definition of CVC mixing could chill legitimate activity and create a large reporting burden for covered financial institutions.
That is a significant policy signal.
Public blockchains are transparent by default, which means privacy-enhancing tools can have both legitimate and illicit uses. A rule that defines mixing too broadly can potentially capture ordinary privacy techniques alongside activity designed to launder criminal proceeds.
FinCEN's withdrawal does not settle that policy debate. It does, however, end this particular Section 311 rulemaking.
What changes now?
The most immediate change is regulatory certainty around these two specific proposals.
1. The proposed special self-hosted wallet reporting regime is gone
Banks and MSBs will not become subject to the additional $3,000 recordkeeping and $10,000 reporting framework proposed in the 2020 NPRM merely because that proposal remained pending.
FinCEN states that it will take no further action on that NPRM.
2. The proposed Section 311 mixer reporting regime is gone
The 2023 finding and proposed special measure targeting international CVC mixing have been withdrawn.
Covered financial institutions therefore do not have to prepare for that specific proposed reporting framework to become final in its current form.
3. The withdrawals reduce regulatory overhang
For years, both proposals remained unresolved in the U.S. regulatory pipeline.
Their formal withdrawal removes uncertainty over whether FinCEN might finalize those specific texts after long periods of inactivity.
For exchanges, compliance teams, wallet developers and self-custody users, that is meaningful even though no existing final rule was repealed.
Why it matters
FinCEN's decision removes two long-running sources of regulatory uncertainty for the U.S. crypto industry.
For self-custody users, the withdrawal means the specific 2020 framework for additional reporting and recordkeeping around certain transactions involving unhosted wallets will not become a final rule.
For exchanges, wallet developers and compliance teams, the decision also removes the immediate prospect of implementing the broad 2023 Section 311 reporting regime for international CVC mixing.
The withdrawals do not eliminate existing AML, Bank Secrecy Act or sanctions obligations, but they narrow the set of proposed federal requirements that the crypto industry had been preparing for.
What does not change?
The withdrawals are important, but they should not be interpreted as a general rollback of U.S. anti-money-laundering regulation.
Existing Bank Secrecy Act obligations remain
Regulated banks and MSBs remain subject to the Bank Secrecy Act and applicable AML/CFT requirements.
Depending on the institution, activity and facts, those obligations can include customer identification, AML programs, suspicious activity monitoring and reporting, recordkeeping and information requirements that already exist independently of the withdrawn proposals.
FinCEN's existing guidance on convertible virtual currency also explains that administrators and exchangers may qualify as money transmitters depending on their activities, while users acting on their own behalf are treated differently.
The Travel Rule has not been repealed
Where an activity constitutes a covered funds transmittal, existing information-transmission requirements can still apply to regulated institutions.
The withdrawal of the self-hosted wallet proposal does not itself cancel the existing Travel Rule framework.
Sanctions rules remain separate
OFAC sanctions compliance is a separate legal regime.
The withdrawal of a FinCEN proposed rule does not automatically remove sanctions restrictions involving designated persons, entities, addresses or jurisdictions.
Suspicious transactions can still trigger reporting
A transaction involving a self-hosted wallet or a mixer is not automatically exempt from existing suspicious-activity obligations simply because these proposals were withdrawn.
The relevant question remains whether a regulated institution has obligations under existing law based on the specific facts and risk indicators.
What crypto users should know
The practical takeaway depends on how a person uses crypto.
Users who simply hold Bitcoin or Ethereum in a self-custody wallet are not becoming subject to a new FinCEN wallet-reporting regime under the withdrawn 2020 proposal.
Users who move funds through regulated exchanges can still encounter KYC, transaction monitoring and compliance checks under existing law.
The withdrawal of the mixer proposal also does not mean every mixer or privacy tool is automatically lawful. FinCEN says it will continue monitoring mixing activity for illicit-finance risks.
For most users, the change is therefore best understood as the removal of two proposed rules rather than the removal of U.S. crypto compliance requirements generally.
What does this mean for self-custody wallet users?
For ordinary users, the clearest takeaway is that the United States is not implementing the special 2020 FinCEN reporting regime for certain transactions involving self-hosted wallets.
That is relevant to users who hold Bitcoin, Ether or other supported assets in wallets where they control their own private keys.
But it does not mean that transactions between an exchange and a self-custody wallet become invisible to compliance systems.
A regulated exchange can still apply risk controls, request information, monitor transaction patterns or review blockchain activity under its existing compliance program.
The withdrawal changes the proposed federal reporting framework; it does not create a right to anonymous use of regulated financial institutions.
For users who prefer direct control of their assets, Terenval Wallet is a self-custody wallet use case that is separate from exchange-based custody.
What does this mean for Bitcoin users?
The Bitcoin protocol is not changed by either withdrawal.
A user can still:
- hold BTC in a self-custody wallet;
- transfer BTC on-chain;
- withdraw BTC from an exchange subject to that exchange's policies and applicable law;
- receive BTC directly to a wallet controlled by the user.
The main regulatory significance lies in how regulated intermediaries treat transfers to and from external wallets.
The withdrawal means the specific proposed FinCEN reporting framework from 2020 will not move forward.
It does not eliminate every compliance check that an exchange, bank or MSB may perform.
What does this mean for Ethereum users?
The same broad distinction applies to Ethereum.
Holding ETH or tokens in a self-custody wallet is not the same activity as operating a regulated exchange or money transmission business.
The withdrawal does not change Ethereum itself, smart contracts or the technical ability to self-custody assets.
It may, however, reduce the possibility that the specific 2020 reporting proposal would become an additional compliance layer when regulated intermediaries interact with external wallets.
What does this mean for DeFi?
The withdrawals are relevant to DeFi, but they are not a comprehensive DeFi safe harbor.
Many decentralized systems use transaction patterns that can overlap with concepts FinCEN discussed in the 2023 mixing proposal, including:
- pooling assets;
- routing transactions through smart contracts;
- splitting or batching transactions;
- automated transaction execution;
- privacy-enhancing mechanisms.
The withdrawal reduces the risk that the specific 2023 Section 311 proposal will be finalized with its broad original definition.
But DeFi protocols, interfaces, developers, operators and users can still face separate legal questions under money transmission rules, sanctions law, securities law, commodities law and other frameworks depending on the facts.
Are crypto mixers now legal in the United States?
The safest answer is: the withdrawal does not create a blanket legal status for all mixers.
FinCEN withdrew one proposed Section 311 finding and special measure.
The agency explicitly said that illicit actors continue to use mixers and that it will keep monitoring mixer activity for indicators of money laundering, terrorist financing and other illicit finance.
A particular mixer, operator or transaction can still raise issues under other laws, sanctions rules or enforcement authorities.
So the correct conclusion is not "mixers are legal now."
The correct conclusion is: this specific proposed FinCEN special measure has been withdrawn.
Does the withdrawal end KYC for crypto exchanges?
No.
The withdrawals do not abolish KYC, AML or Bank Secrecy Act obligations for regulated cryptocurrency businesses.
A compliant exchange may still be required to identify customers, maintain an AML program, monitor suspicious activity and comply with applicable reporting and recordkeeping requirements.
The decision is narrower: FinCEN is not finalizing these two specific proposed rulemakings.
Why is the decision important for crypto privacy?
The mixer withdrawal contains unusually direct recognition of the tension between illicit-finance controls and legitimate financial privacy.
FinCEN acknowledged concerns that an expansive definition of mixing could discourage legitimate activity.
That matters because public blockchains expose transaction histories in ways that traditional payment systems generally do not expose to every observer.
Privacy tools can therefore be used by:
- users who do not want their entire financial history publicly linked;
- businesses protecting commercially sensitive payments;
- individuals separating wallet identities;
- as well as criminals attempting to conceal illicit proceeds.
Regulators still have to distinguish between those use cases.
The withdrawal suggests Treasury is reconsidering whether the 2023 proposal drew that line correctly.
What does this mean for crypto exchanges and MSBs?
For regulated exchanges and money services businesses, the main impact is the removal of prospective compliance obligations associated with the two proposals.
That can reduce:
- future systems-development requirements;
- additional data collection tied specifically to the withdrawn wallet proposal;
- potential bulk reporting associated with the broad mixer proposal;
- uncertainty over how to classify complex on-chain activity.
But compliance departments cannot simply switch off existing controls.
The underlying Bank Secrecy Act framework remains, and FinCEN continues to treat digital-asset illicit finance as an enforcement priority.
Is this part of a broader U.S. crypto policy shift?
Yes, but the scope should not be overstated.
FinCEN described the withdrawals as part of efforts to ensure digital-asset regulation is fit-for-purpose.
The move also fits a broader U.S. debate over how to regulate crypto market structure, custody, privacy, exchanges and derivatives without applying rules designed for traditional financial intermediaries too mechanically to decentralized technology.
At the same time, other regulators continue their own rulemaking.
For example, the CFTC has separately opened a rulemaking process around certain leveraged, margined or financed retail crypto transactions. See our analysis: CFTC Proposes Federal Framework for Leveraged Crypto Trading.
The FinCEN withdrawals therefore should be viewed as one piece of a larger regulatory restructuring, not the end of U.S. crypto regulation.

Frequently asked questions
Did FinCEN ban self-hosted wallets?
No.
The 2020 proposal did not ban self-hosted wallets. It proposed additional reporting, recordkeeping and verification requirements for banks and MSBs handling certain transactions involving unhosted or otherwise covered wallets.
That proposal has now been withdrawn.
Is a self-hosted wallet the same as a non-custodial wallet?
In ordinary crypto usage, the terms overlap substantially.
A self-hosted or non-custodial wallet generally means that the user controls the private keys rather than a third-party custodian.
FinCEN used the term unhosted wallet in the 2020 proposal.
Is the $3,000 crypto wallet rule still coming?
Not from this NPRM.
The withdrawn proposal would have required records for certain covered transactions greater than $3,000.
FinCEN says it will take no further action on that rulemaking.
Is the $10,000 self-hosted wallet reporting rule in force?
No.
The proposal would have required reports for certain transactions above $10,000, including qualifying transactions aggregating above $10,000 within 24 hours.
It never became a final rule and has now been withdrawn.
Did FinCEN withdraw the crypto mixer rule?
Yes.
FinCEN withdrew both its 2023 finding that international CVC mixing is a class of transactions of primary money laundering concern and the accompanying proposed special measure.
Does that mean mixers are safe from future regulation?
No.
FinCEN explicitly says it will continue monitoring CVC mixer activity and may take future steps to address illicit finance.
Does this affect the Bank Secrecy Act?
The Bank Secrecy Act remains in force.
The withdrawals remove two proposed rulemakings; they do not repeal the BSA.
Does this change crypto exchange KYC requirements?
Not generally.
Existing obligations applicable to regulated exchanges, banks and MSBs remain separate from the withdrawn proposals.
Does this change self-custody for Bitcoin or Ethereum?
The withdrawals do not change the Bitcoin or Ethereum protocols and do not prohibit users from controlling their own private keys.
Their practical impact is primarily on proposed obligations for regulated intermediaries interacting with certain external wallets or mixing activity.
Bottom line
FinCEN's October 2026 decision is one of the most consequential U.S. regulatory developments for crypto self-custody and privacy in years.
The agency has formally ended two major proposed rulemakings:
- the 2020 proposal that would have added special reporting and recordkeeping requirements for certain transactions involving unhosted or self-hosted wallets; and
- the 2023 Section 311 proposal that would have imposed enhanced reporting requirements around international CVC mixing.
For self-custody users, the decision removes the immediate prospect of the specific wallet-reporting framework proposed in 2020.
For privacy-focused users and crypto infrastructure developers, withdrawal of the mixer proposal reduces the risk that its broad original definition will become law in its current form.
For exchanges and other regulated institutions, however, the message is not deregulation without limits.
Existing AML, Bank Secrecy Act, sanctions and suspicious-activity obligations remain.
As of October 6, 2026, the correct interpretation is therefore narrow but important: FinCEN has withdrawn two proposed crypto rules, not withdrawn from crypto enforcement.
