Re: Docket Quantity FINCEN–2023–0016 – Proposal of Particular Measure Relating to Convertible Digital Foreign money Mixing as a Class of Transactions of Main Cash Laundering Concern

Pricey Director Gacki:

We respect the chance to touch upon Docket Quantity FINCEN-2023-0016 (the “Mixing Transaction NPRM”), launched by the Monetary Crimes Enforcement Community (“FinCEN”) on October 22, 2023.^[1] We’re quite a lot of unaffiliated corporations that depend on vital cybersecurity safeguards and privacy-enabling software program to guard our companies and our customers. The acute breadth of the foundations proposed by the Mixing Transaction NPRM would overly burden our use of such applied sciences in ways in which wouldn’t help FinCEN in reaching its mandate of stopping cash laundering and different illicit use of cash. Consequently, we write to precise our grave issues relating to the novelty and scope of the Proposed Particular Measures and the insufficient definitions contained therein.^[2]

The Proposed Particular Measures would unreasonably infringe upon the legit monetary privateness pursuits of cryptocurrency customers, and would apply to quite a lot of digital strategies that aren’t mixing transactions in any respect, however quite merely signify good cybersecurity practices. Furthermore, the Proposed Particular Measures are pointless to realize FinCEN’s purpose, and we encourage FinCEN to both withdraw the Mixing Transaction NPRM altogether or to pursue a much less invasive, much less restrictive, and simpler strategy—the identical strategy it has used since its first enforcement actions within the cryptocurrency area in 2013—to enforcement in opposition to particular dangerous actors.

1. FinCEN ought to train warning and both withdraw solely or narrowly tailor the Mixing Transaction NPRM as a result of if adopted, the Mixing Transaction NPRM wouldn’t solely signify the primary time FinCEN used its Part 311 powers in opposition to a category of transactions, but in addition the primary time FinCEN has ever imposed Particular Measure 1.

Traditionally, FinCEN has exercised warning in making designations beneath Part 311 and implementing Particular Measures. Part 311 (31 U.S.C. 5318A), authorizes the U.S. Division of Treasury (“Treasury”) to designate a overseas jurisdiction, monetary establishment, class of transactions, or sort of account as being of “main cash laundering concern” and impose a number of of 5 doable “particular measures.” Treasury delegated that authority to FinCEN, which has used its energy fairly sparingly since Part 311’s enactment. The primary Part 311 motion instituted by FinCEN within the digital forex area occurred in 2013, when FinCEN instituted particular measures in opposition to Liberty Reserve. Previous to that point, between 2002 and 2013, FinCEN had solely ever applied particular measures in opposition to simply 4 jurisdictions and 13 monetary establishments. After a protracted authorized battle relating to a Part 311 motion between 2015-2017, FinCEN appeared reluctant to make use of its Part 311 powers extensively. ^[3] The creation of the World Investigations Division (GID) in 2019 ^[4] and the enactment of the Anti-Cash Laundering Act of 2020, which elevated FinCEN’s authority “to ban or impose circumstances upon sure transmittals of funds (to be outlined by the Secretary) by any home monetary establishment or home monetary company,” ^[5] coincided with an uptick in the usage of Part 311 powers and a broadening of FinCEN’s consideration to all 5 obtainable Particular Measures.

Importantly, all through its use of Part 311, FinCEN historically imposes Particular Measure Quantity 5 to isolate a selected overseas monetary establishment and forestall it from accessing the U.S. monetary system. Till this Mixing Transaction NPRM, FinCEN has solely used Particular Measure Number one one different time—in 2012 in opposition to JSC CredexBank (“Credex”).^[6] FinCEN later withdrew that proposed rule in 2016. ^[7] If adopted, the Mixing Transaction NPRM would represent the primary time FinCEN has imposed Particular Measure Number one in exercising its Part 311 Powers. Furthermore, this Mixing Transaction NPRM represents the very first time FinCEN has sought to designate a whole class of transactions as a main cash laundering concern. We encourage FinCEN to train excessive warning within the train of its Part 311 powers in such a novel method—the first-ever designation of a category of transactions and the first-ever imposition of Particular Measure 1.

Exercising warning in Part 311 powers displays the seriousness of Treasury’s coverage functions for invoking its powers to make main cash laundering concern designations and impose particular measures—particularly, to behave as a sign to the world that FinCEN is “severe about making certain that the worldwide monetary system is safeguarded in opposition to the specter of cash laundering.” ^[8] As Treasury defined within the press launch asserting the very first use of its Part 311 powers in 2002, when FinCEN makes use of Part 311, “[FinCEN] inform[s] the world clearly that these jurisdictions [or entities or transactions] are dangerous for enterprise and that their monetary controls can’t be trusted.” ^[9] For the explanations additional defined under, FinCEN’s concentrating on of convertible digital forex (“CVC”) ^[10] purported “mixing” transactions doesn’t obtain these goals. Reasonably than goal transactions which can be “dangerous for enterprise,” the Mixing Transaction NPRM targets an excessively broad vary of technical approaches used as finest practices each by companies and people for making certain the safety of CVC and impinges on privateness rights of legit customers of CVC. In an try to train authority it has by no means used earlier than (class of transactions) via a particular measure it has by no means beforehand imposed efficiently (particular measure 1), FinCEN created a proposed rule fraught with misunderstandings and overreach. We urge FinCEN to withdraw the rule and rethink its strategy to this novel use of its authority.

2. The Mixing Transaction NPRM proposes a rule that’s an improper and overbroad utility of Part 311 measures to realize transaction surveillance and suppression that FinCEN doesn’t in any other case have a lawful foundation to undertake.

Though the Mixing Transaction NPRM ostensibly designates a category of transactions as being of Main Cash Laundering Concern, its actual aim is to uncover an alternate technique for gathering details about and suppressing the usage of digital forex basically. The Mixing Transaction NPRM is an improper and overbroad utility of Part 311 measures for that objective. Certainly, though the Mixing Transaction NPRM allegedly sanctions a category of transactions, it inconsistently all through refers to “CVC mixers,” “CVC mixing” and “CVC mixing providers” by reference to particular enterprise entities ^[11] and as a kind of enterprise mannequin extra usually.^[12] If FinCEN has cause to imagine particular entities conduct illicit actions, FinCEN may use the Part 311 powers it has historically and efficiently used to focus on particular entities as monetary establishments of main cash laundering concern. Such an strategy presents a extra focused method to deal with precise cash laundering whereas defending legit customers of legit privacy-enhancing instruments.

Notably, Treasury has individually sanctioned what it refers to as CVC mixing transactions via its Workplace of Overseas Asset Management (OFAC) authority to designate folks or property who conduct transactions with particularly designated overseas jurisdictions recognized via govt order as posing terrorist threats. ^[13] Treasury is at present dealing with authorized challenges to, and has been extensively criticized for, its try to sanction the Twister Money open supply software program as property of a non-existent entity Treasury alleges known as “the Twister Money DAO entity.” ^[14] Though we agree with the various arguments as to why Treasury’s OFAC motion with regard to Twister Money software program is an instance of company overreach, we want to make a unique however associated level right here. To justify its OFAC sanctions in opposition to the Twister Money software program, Treasury needed to designate the software program as property of an entity. ^[15] OFAC formally defined as a part of defending its sanction to a decide that the Twister Money software program was property beneath Treasury’s laws as a result of it fell throughout the broad attain of “any contract in anyway.” ^[16] Though the definition of “transaction” beneath the BSA laws is sort of broad, it doesn’t embody “any contract in anyway” however quite facilities on financial transfers and particular providers provided by monetary establishments, and supplies a catch-all for “every other cost, switch, or supply by, via or to a monetary establishment, by no matter means effected.” ^[17] No a part of the definition relevant to CVC mixing can be a contract.^[18]

In different phrases, in proposing the Mixing Transaction NPRM, one arm of Treasury is classifying CVC mixing as a transaction sort whereas one other arm of Treasury argues that mixing is a contract for providers. Below the laws governing each enforcement actions, mixing exercise can’t be each a transaction sort and a contract for service concurrently. Treasury’s try to designate mixing software program as each a kind of transaction and a contract is proof of the arbitrary and capricious nature of its try to control open-source software program that enhances the digital privateness of legit CVC customers. To the extent that FinCEN actually desires to focus on non-custodial, open-source software program that people can use on their very own accounts, FinCEN exceeds its statutory authority.

Certainly, instruments that improve digital privateness in CVC transactions merely search to allow a type of digital money. Consequently, in its rush to discover a method to suppress CVC mixing transactions, by whichever means, even when inconsistent amongst completely different inner branches of its personal company, FinCEN’s Mixing Transaction NPRM quantities to an try to sanction “all transactions performed in money,” which is each unattainable and an unreasonable over-extension of its rulemaking authority.

3. The Mixing Transaction NPRM ought to be withdrawn as a result of the proposed definition of “CVC mixing” is overbroad and targets lawful exercise in a method that makes the company’s proposed motion arbitrary and capricious.

Setting apart FinCEN’s personal obvious confusion about whether or not CVC mixing is a transaction, a service, a enterprise, or a selected enterprise entity, when FinCEN does try to outline the “class” of transactions that it considers to be CVC mixing, the Mixing Transaction NPRM’s definition of “mixing” is extraordinarily broad and consists of quite a few actions routinely performed by legit customers as a matter of routine security precautions in on-line transacting in CVC. Particularly, the Mixing Transaction NPRM supplies:

The time period “CVC mixing” means the facilitation of CVC transactions in a way that obfuscates the supply, vacation spot, or quantity concerned in a number of transactions, no matter the kind of protocol or service used, reminiscent of: (1) pooling or aggregating CVC from a number of individuals, wallets, addresses or accounts; (2) utilizing programmatic or algorithmic code to coordinate, handle, or manipulate the construction of a transaction; (3) splitting CVC for transmittal and transmitting the CVC via a sequence of unbiased transactions; (4) creating and utilizing single-use wallets, addresses, or accounts, and sending CVC via such wallets, addresses, or accounts via a sequence of unbiased transactions; (5) exchanging between kinds of CVC or different digital property; ^[19] or (6) facilitating user-initiated delays in transactional exercise. ^[20]

Certainly, many of the actions captured by the proposed definition of CVC mixing are thought of established finest practices throughout the business for the use and safekeeping of CVC. Particularly, the proposed definition encompasses lightning transactions, single-use wallets, atomic swaps, decentralized finance protocols, privateness coin options, and multi-signature wallets, amongst different issues. The principle commonality amongst this broad vary of software program instruments is that they improve digital privateness and provide primary cyber-security strategies to house owners or custodians of CVC. Using these strategies to safeguard beneficial digital property is as routine and mundane and freed from illicit objective as utilizing two-factor authentication to safe a digital pockets containing cost card info or an X (previously Twitter) account to stop an unauthorized announcement.^[21]

4. The Mixing Transaction NPRM ought to be withdrawn as a result of its inaccurate depiction of normal safety practices as “mixing” impermissibly restricts the capability of customers to guard their property in order that FinCEN can conduct a fishing expedition.

The proposed rule describes as purple flags such on a regular basis practices as “creating and utilizing single deal with wallets” and “splitting CVC for transmittal.” ^[22] The usual observe amongst cryptocurrency customers is to alter addresses with each transaction. For instance, Coinbase Trade describes to their customers that: “[w]e mechanically generate a brand new deal with for you after each transaction you make or when funds are moved between your pockets and our storage system. That is executed to guard your privateness, so a 3rd celebration can not view all different transactions related together with your account just by utilizing a blockchain explorer.” ^[23]

The truth that a small subset of customers, who could also be criminals, interact in the identical operational safety practices as peculiar customers doesn’t make these operational safety practices suspect. The truth that criminals could use two-factor authentication to guard the safety of their on-line functions doesn’t imply that the usage of two-factor authentication is itself an indicator or facilitator of legal exercise. In precisely the identical method, the truth that customers don’t reuse Bitcoin addresses is merely indicative of primary operational safety.

In an obvious recognition of the truth that these instruments legitimately allow vital cyber-security precautions, FinCEN exempts monetary establishments from reporting on any of their very own mixing transactions that they might conduct in the middle of offering providers to the general public.^[24] By exempting monetary establishments from the rule, FinCEN creates a regime the place monetary establishments can take correct cyber-security measures for utilizing CVC, however common folks can not.

Maybe much more problematic, all through the Mixing Transaction NPRM, FinCEN justifies the proposed rule as essential to allow legislation enforcement and the company to raised perceive the transactions and the extent to which illicit exercise happens via CVC mixing. ^[25] The extraordinary and by no means earlier than efficiently invoked Part 311 energy to designate a category of transactions and implement particular measure 1 shouldn’t be acceptable to be used in a fact-finding mission. Using such overly broad definitions as proposed within the Mixing Transaction NPRM for the aim of authorizing an invasive fact-finding mission represents an arbitrary and capricious use of FinCEN’s delegated rulemaking authority as a result of FinCEN’s justification for the rule lies outdoors of the statutory standards for figuring out a category of transactions is of main cash laundering concern.

Particularly, FinCEN is statutorily required to contemplate the next components when figuring out {that a} class of transactions is of main cash laundering concern: (1) the extent to which the category of transactions is used to facilitate or promote cash laundering in or via a jurisdiction outdoors of america, together with cash laundering exercise with connections to worldwide terrorism, organized crime, and proliferation of WMDs and missiles; (2) the extent to which a category of transactions is used for legit enterprise functions; and (3) the extent to which motion by FinCEN would guard in opposition to worldwide cash laundering and different monetary crimes.” ^[26] All through the Mixing Transaction NPRM, FinCEN acknowledges that on account of a scarcity of knowledge and a lack of expertise of CVC mixers, it can not sufficiently assess the extent to which CVC mixing and the proposed rule measures up beneath any of those three standards. ^[27] FinCEN’s evaluation in the end boils right down to: FinCEN doesn’t have adequate info to correctly assess the statutory standards required to justify the proposed rule, so the proposed rule is justified as a result of, in FinCEN’s personal phrases, it “is critical to raised perceive the illicit finance threat posed by CVC mixing.” ^[28] Utilizing a sanction to acquire the knowledge essential to justify imposing the sanction even when the company is aware of that doing so will seemingly impose a excessive burden on legit makes use of and monetary establishments is the definition of arbitrary and capricious regulatory motion.

5. The Mixing Transaction NPRM ought to be withdrawn or considerably narrowed in scope as a result of FinCEN’s required statutory evaluation fails to adequately worth the legit makes use of of CVC mixing providers and unduly burdens legit customers and monetary establishments.

FinCEN admits that public blockchains “make it doable to know somebody’s whole monetary historical past on the blockchain” ^[29] and that it “acknowledges that there are legit the explanation why accountable actors would possibly need to conduct monetary transactions in a safe and personal method given the quantity of knowledge obtainable on public blockchains.” ^[30] But, in the identical doc, alleges that the Mixing Transaction NPRM is critical as a result of CVC “shouldn’t be with out its dangers and, specifically, the usage of CVC to anonymize illicit exercise undermines the legit and revolutionary makes use of of CVC.” ^[31] These two propositions can’t be concurrently correct.

As a matter of technical actuality, FinCEN’s assertion that public blockchains expose a consumer’s whole monetary historical past on the blockchain to the general public for everybody to see and examine is appropriate. ^[32] Certainly, that creates the elemental want for legit CVC customers to conduct CVC mixing transactions—to reintroduce the identical degree of economic privateness that they take pleasure in within the conventional monetary system ^[33] to their transactions by way of CVC (for instance, the normal monetary system doesn’t expose a shopper’s whole bank card historical past to the general public, and certainly, federal legislation requires that monetary establishments shield such info from being uncovered to the general public ^[34]). ^[35]

Guaranteeing their CVC transactions take pleasure in the identical degree of privateness as transactions in conventional finance reduces the potential hazard of non-public hurt to legit customers and allows legit customers to keep away from waiving their constitutional proper to privateness. When the identification of a legit CVC consumer is thought and linked to the wallets holding CVC property, the consumer turns into a goal for kidnap, theft, extortion, and hacking schemes. ^[36] Additional, due to this inherent transparency by design of public blockchains, the Fifth Circuit lately dominated that no expectation of privateness exists for customers of permissionless public blockchains who take no extra motion to privacy-protect their transactions. ^[37] Reliable customers make use of privacy-enhancing software program when transacting in CVC with a view to keep away from inadvertently waiving their constitutionally protected privateness rights.

In the end, FinCEN has fully failed in its obligation to adequately account for the impression on legit customers as required by its rulemaking authority. In defending its number of particular measure 1 over 2 via 5, FinCEN emphasizes, with out rationalization, that particular measure 1—extra file retaining—permits legit customers to proceed utilizing privacy-enhancing software program with out interruption. ^[38] That is false, as coated entities should report on any transaction that will have concerned CVC mixing and a overseas jurisdiction. Certainly, learn broadly, it’s doable that the foundations proposed by the Mixing Transaction NPRM require reporting on transactions that contain CVC that had been transacted via mixing software program at any level within the asset’s transaction historical past. Such reporting straight impedes the explanations for which legit customers make use of mixing software program (to boost monetary privateness) by requiring the elimination of economic privateness (it’s not a non-public transaction if an middleman should surveil and report on the transaction). Software program instruments like mixers that improve digital monetary privateness present a real digital equal to money. Notably, transactions in money usually are not topic to guidelines reminiscent of these proposed within the Mixing Transaction NPRM. In an obvious acknowledgment of this deep and inherent battle between the foundations proposed by the Mixing Transaction NPRM and the legit makes use of to which legit customers put CVC mixing software program, FinCEN itself predicts that the rule will chill the usage of CVC mixers.

6. The Mixing Transaction NPRM ought to be withdrawn as a result of it requires coated monetary establishments to carry out legislation enforcement’s operate to perform FinCEN’s AML objectives, which FinCEN, DOJ, and legislation enforcement can obtain utilizing current instruments after they have a correct authorized foundation to make use of these instruments.

Just like the definitions of CVC mixing and CVC mixer, the Mixing Transaction NPRM’s info reporting necessities display a deep lack of technological understanding. Notably, the entire transaction info that the Mixing Transaction NPRM proposes to incorporate in required studies by coated monetary establishments includes information that, in most circumstances, FinCEN can simply as simply receive itself via blockchain information analytics. Equally, the shopper info that FinCEN would require coated monetary establishments to report consists of the identical varieties of knowledge such establishments should already report if a transaction raises adequate purple flags to set off the submitting of a Suspicious Exercise Report (SAR). Nonetheless, the Mixing Transaction NPRM seeks to require coated monetary establishments to file such studies on each single transaction for which the CVC concerned could have ever been transacted via the extraordinarily broad set of software program that FinCEN’s proposed rule defines as CVC mixing software program. In different phrases, as a result of legislation enforcement investigations into exercise involving CVC are typically tougher, FinCEN seeks to impose broad surveillance of people with out trigger via coated monetary establishments. Coated monetary establishments mustn’t must grow to be de facto legislation enforcement officers to make investigations simpler for FinCEN.

FinCEN, the Division of Justice, and legislation enforcement have beforehand and efficiently employed the very instruments FinCEN asks monetary establishments to make use of for reporting compliance beneath the Mixing Transaction NPRM to focus on particular illicit actors. FinCEN has demonstrated that it is aware of easy methods to correctly examine and implement in opposition to particular custodial CVC mixing service suppliers that aren’t complying with the laws to which they’re topic. Particularly concentrating on illicit actors about which FinCEN and legislation enforcement have constructed a transparent, sturdy case utilizing the obtainable blockchain information analytics instruments higher balances the necessity to fight illicit CVC mixing with the legit use of CVC mixing by people searching for to guard their legit, constitutionally and statutorily protected privateness pursuits.

For the entire causes mentioned above, we urge FinCEN to withdraw the Mixing Transaction NPRM altogether.
