TLDR
- The Financial Crimes Enforcement Network has abandoned a 2023 proposal targeting cryptocurrency mixing services.
- A separate 2020 proposal mandating identity verification for self-custody wallet transfers has also been scrapped.
- The agency acknowledged its mixing definition was too expansive and could penalize legitimate privacy seekers.
- Since neither rule was ever enacted, existing regulations remain in effect without changes.
- Digital asset advocacy organizations praised the withdrawal as a positive development.
The Financial Crimes Enforcement Network, a division of the US Treasury Department, has formally rescinded two regulatory proposals concerning digital currencies. The announcement appeared in the Federal Register on Monday.
The first rule, originally unveiled in October 2023, sought to designate cross-border cryptocurrency mixing as a “primary money laundering concern.” The second, dating to December 2020, aimed to mandate financial institutions verify customer identities for transactions involving self-custody wallets.
According to the agency’s statement, this action aligns with the current administration’s regulatory rollback initiative. FinCEN emphasized its commitment to ensuring digital asset oversight remains “fit-for-purpose.”
Reasoning Behind the Mixer Proposal Withdrawal
The 2023 regulatory framework employed an expansive interpretation of mixing activities. It encompassed fund aggregation, transaction fragmentation, and the deployment of disposable wallet addresses designed to mask cryptocurrency origins or destinations.
Financial institutions would have been obligated to document wallet addresses, transaction identifiers, and internet protocol addresses associated with such activities. The agency acknowledged that public feedback highlighted concerns regarding this overly inclusive definition.
Officials noted the regulation risked imposing substantial compliance costs on reporting entities. Additionally, they recognized it could deter individuals from employing mixers for legitimate confidentiality purposes unrelated to criminal enterprise.
The agency referenced a July 2025 analysis produced by the President’s Working Group on Digital Asset Markets. That document recognized that law-abiding individuals may leverage mixing services to maintain financial confidentiality while transacting on transparent blockchain networks.
Nevertheless, FinCEN maintained its position that certain criminals exploit these tools to evade law enforcement scrutiny. The bureau confirmed it will continue monitoring mixer operations for indications of unlawful conduct.
The Self-Custody Wallet Proposal
The second rescinded regulation originated in December 2020, introduced during the closing days of the previous Trump presidency.
Under that framework, financial institutions would have been required to authenticate identities for wallet transfers exceeding $3,000. Transactions surpassing $10,000 would have triggered mandatory reporting obligations to the enforcement network.
The agency stated this rule is likewise being eliminated as part of its broader reassessment of digital asset regulatory frameworks. Officials confirmed no additional enforcement actions will be pursued.
Because neither regulation advanced beyond the proposal stage, existing compliance obligations for financial institutions and cryptocurrency businesses remain unaltered at present.
Coin Center, an advocacy organization focused on cryptocurrency policy, published a response to the development. The organization argued the mixing framework’s scope was excessively broad and risked capturing standard privacy-enhancing techniques employed by ordinary digital currency holders.
The advocacy group further contended the wallet verification requirement would have established disparate regulatory treatment for cryptocurrency transfers relative to traditional financial transactions.
The Crypto Council for Innovation issued its own statement. The organization shared on social media platform X that the withdrawal represents a favorable outcome for the digital asset sector.
This development arrives amid broader regulatory transformations. The Treasury Department removed Tornado Cash, a cryptocurrency mixing protocol, from its sanctions roster in March 2025 following a judicial decision unfavorable to the Office of Foreign Assets Control.
A distinct Treasury Department communication to Congress this past March conceded that mixing services can fulfill lawful privacy functions. Treasury officials declined to provide additional commentary when contacted by media representatives.
