U.S. DEPARTMENT OF THE TREASURY
Remarks by Assistant Secretary Elizabeth Rosenberg at the
Crypto Council for Innovation
November 18, 2022

As prepared for delivery
Thank you to the Crypto Council for Innovation for hosting me and bringing together
representatives from across industry today. My name is Elizabeth Rosenberg and Iʼm the
Assistant Secretary for Terrorist Financing and Financial Crimes at the U.S. Treasury.
In mid-September and pursuant to President Bidenʼs Executive Order on Digital Assets,
Treasury published an Action Plan to Mitigate the Illicit Finance Risks of Digital Assets

–a

roadmap for how the U.S. government, led by the Treasury Department, will bring greater
transparency to the digital asset sector. The report identifies seven priority actions, including
improving global anti-money laundering/countering the financing of terrorism (AML/CFT)
regulation and enforcement, strengthening U.S. supervision of the virtual asset service
providers sector, and engaging with the private sector.
Collaborative work both with the private sector, and between private sector entities, is
critical for detecting and countering illicit finance. To deepen our insight and engagement
with industry, in mid-September, we released a Request for Comment, seeking feedback on
the Action Plan, our assessment of illicit financing risks, and opportunities to strengthen
public-private collaboration.
The comment period ended on November 3 and I want to thank industry for the all the
submissions.
While we continue to review the comment letters in detail, I wanted to highlight two specific
issues addressed in the comment letters: a need for regulatory clarity and more publicprivate engagement. Many of the comments acknowledged that in the United States, virtual
asset service providers are subject to a regulatory framework for AML/CFT and have
sanctions obligations. With this in mind, industry commenters identified specific areas, such
as questions around decentralized finance (DeFi), where they could benefit from additional

regulatory clarity or guidance. As a matter of policy, we want to ensure that industry has a
clear understanding of AML/CFT and sanctions obligations. Therefore, we will be reviewing
the specific issues industry identified in the comments and explore how, whether through
regulation, guidance, or outreach, we can best address industry questions and uncertainty.
Second, we received thoughtful feedback on opportunities to expand and formalize our
engagements with the virtual assets industry. I recognize that industry has unique insight
into illicit finance threats. Stronger two-way dialogue can also strengthen the U.S.
governmentʼs understanding of technological innovations and changes, as well as create
greater opportunities for industry to identify areas where these innovations may result in
regulatory uncertainty.
I am here today, as part of that larger e�ort, to build direct relationships with industry, solicit
further feedback, and learn about developments in the virtual asset ecosystem. To that end, I
want to take a moment to discuss some of the policy questions surrounding our approach to
mixers following Treasuryʼs designations of Blender and Tornado Cash. We recognize that, in
some instances, virtual assets may provide more insight into financial activities by virtue of
public blockchains, which can be used to support AML/CFT compliance. Still, I understand
that some virtual asset users may want to preserve their privacy when conducting
transactions.
As was clearly stated in President Bidenʼs Executive Order, we want to ensure that safeguards
are in place to promote the responsible development of virtual assets to maintain privacy
and shield against arbitrary or unlawful surveillance. The challenge is that mixers, as
currently operating, provide anonymity, a way for illicit actors to obfuscate the movement
and the origin or destination of funds, while reducing law enforcementʼs visibility into these
transfers. The challenge is that while these services o�en operate as money transmitters and
thus have regulatory reporting obligations, they may deliberately operate in a non-compliant
manner to make it more di�icult for regulators and law enforcement to trace illicit funds.
Illicit actors are capitalizing on these vulnerabilities. The Democratic Peopleʼs Republic of
Koreaʼs (DPRK) Lazarus Group uses mixers to launder proceeds of virtual currency heists.
Illicit actors also use mixers to launder proceeds of ransomware, drug tra�icking, and other
criminal activities. We are concerned that mixers are being abused for illicit purposes and we
are therefore compelled to take action to address this risk. In the case of Blender and
Tornado Cash, the Lazarus Group used mixers to obfuscate the source of funds derived from

a March 2022 cyber heist. In addition, malicious cyber actorsʼ used the service provided by
Tornado Cash to launder more than $96 million of funds derived from the June 24, 2022
Harmony Bridge Heist, and at least $7.8 million from the August 2, 2022 Nomad Heist.
The Treasury Department cannot allow such egregious activity to occur. Illicit actors are
abusing mixers to launder funds. It is our goal to be clear about obligations, but we need
industry to take clear steps, in line with AML regulations and sanctions obligations, to
prevent illicit actors from abusing this activity. Our goal and intention is not to deter the
development of technologies that provide privacy for virtual asset transfers. We welcome
opportunities to further engage with industry on how these technologies can both promote
privacy while also mitigating illicit finance risks and complying with regulatory and sanctions
obligations.
Before I turn the discussion over to all of you, I want to thank you all for making time to
speak with me today and sharing your insights. I welcome feedback and hope that we can
use our time to identify how we all, government and industry, can further collaborate to
promote transparency and integrity in the virtual asset ecosystem.
