FinCEN withdraws proposed rules on crypto mixing
- FinCEN formally withdrew proposed regulations targeting crypto mixing services and unhosted wallets.
- Regulators acknowledged the rules would burden banks and chill legitimate financial privacy.
- Coinbase and Coin Center had argued the rules illegally stretched Section 311 of the Patriot Act.
The U.S. Treasury blinked on crypto surveillance.
FinCEN deputy director Jimmy Kirby signed notices formally withdrawing a 2023 proposal targeting digital asset mixing alongside a 2020 rule aimed at self-hosted wallets. The regulatory retreat marks a decisive setback for federal efforts to track unhosted wallets and peer-to-peer privacy tools under the Bank Secrecy Act.
Under the abandoned framework, financial institutions would have been forced to log and report wallet addresses, transaction hashes, and IP addresses for routine privacy-preserving transactions. FinCEN conceded that the proposed requirements risked chilling legitimate activity while imposing severe compliance burdens on banks.
The withdrawal follows aggressive legal pushback led by Coinbase and advocacy group Coin Center. Industry representatives argued that FinCEN stretched Section 311 of the Patriot Act beyond its statutory authority, attempting to treat privacy-enhancing software as a primary money laundering concern without explicit legislative backing.
The policy reversal arrives as regulatory boundaries remain fiercely contested across digital networks. On Bitcoin And, analysts highlighted how state surveillance pressures continue to collide with privacy tools worldwide, from local Bluetooth messaging bans to automated corporate monitoring of private chats.
By dropping both the mixing classification and the unhosted wallet reporting mandates, federal regulators effectively sidelined direct oversight of private wallets for the immediate future. The decision restores a baseline of regulatory predictability for open-source developers and self-custody software users.
For now, self-custody remains beyond Washington's reach.
