DeFi Debrief: Week of August 24, 2026

Treasury Launches Financial Sector Quantum-Readiness Task Force; CCI and BA File Lawsuit Against Illinois Over Digital Asset Tax Act; and more.

Crypto Trade Associations File Lawsuit Against Illinois Over Digital Asset Tax Act

On August 21, 2026, the Crypto Council for Innovation (“CCI”) and the Blockchain Association (“BA”) filed a lawsuit challenging the Illinois Digital Asset Tax Act. Effective January 1, 2027, the Act will impose a 0.2 percent tax on the value of digital assets involved in exchange, transfer, or storage activities, including transfers that have no sale, no gain, and no change in ownership (e.g., moving digital assets between a user’s own wallets or accounts). The complaint argues that Illinois unlawfully singles out digital asset activity, as comparable traditional financial transactions generally are not subject to an equivalent tax.

CCI and BA allege the Act violates the federal Internet Tax Freedom Act (“ITFA”), the dormant Commerce Clause, the Illinois and federal Due Process Clauses, and the Illinois Constitution’s Uniformity Clause. They also raised concerns about the Act’s legislative process, noting that it was added to a 1,500+ page bill on the final day of the Illinois legislative session and passed through both chambers within roughly 24 hours, with limited public comment or debate. The lawsuit asks the court to declare the Act unlawful and seeks an injunction to prevent Illinois officials from implementing or enforcing it. 

The challenge is another example of the growing tension between state-level digital asset regulation and the need for a coherent national framework.

DEF Board Members Co-Author Practical Guide for Financial Institutions and Permissionless Networks

On August 24, 2026, DEF board member Rebecca Rettig (Chief Operating Officer and Chief Legal Officer at Jito Labs), Columbia Business School Adjunct Professor Omid Malekan, and DeFi Education Foundation board member Michael Mosier  (Co-Founder of Arktouros PLLC) published a new paper titled “The Compatibility of Permissionless Networks and Financial Integrity: A Practical Guide for Financial Institutions.” The authors argue that financial integrity laws—including the Bank Secrecy Act, anti-money laundering, and countering the financing of terrorism requirements—and U.S. sanctions laws do not prohibit banks and other financial institutions from using open, permissionless blockchains. Instead, the paper explains that permissionless networks can fully satisfy these requirements if institutions implement controls at the application layer, consistent with the financial sector’s adoption of the internet, where compliance and oversight are applied to activities institutions directly control.

The paper also addresses several common concerns about exposure to illicit actors at the network layer and the provenance of assets, explaining that institutions do not automatically “inherit” sanctions exposure from an asset’s prior interactions. Institutions can instead manage direct exposure through tools such as blockchain analytics, wallet screening, transaction monitoring, and reporting. The paper further considers the confidentiality of onchain data and balancing privacy with compliance.

Treasury Launches Financial Sector Quantum-Readiness Task Force

On August 24, 2026, Treasury announced a new Quantum-Readiness Task Force, following President Trump’s Executive Order 14412, to accelerate the financial sector’s transition to quantum-resistent cryptography. Building on the G7 Cyber Expert Group’s roadmap for transitioning to post-quantum cryptography, the Task Force will bring together government, financial institutions, financial market infrastructures, technology providers, and other private-sector leaders to focus on three workstreams: Sector Alignment & Post-Quantum Cryptography, Third-Party & Vendor Readiness, and Digital Assets & Emerging Technology Risk.

The initiative is relevant for DeFi wallets, blockchain transactions, smart contracts, and other protocol infrastructure that rely heavily on cryptographic systems. Treasury’s explicit focus on digital assets underscores the importance of ensuring that onchain infrastructure can adapt to evolving cryptographic standards while maintaining interoperability and operational resilience.

Notable and Quotable

“Financial institutions can use permissionless networks; concerns about financial integrity laws should not deter them and can be addressed under existing law through a risk-based compliance framework that places controls at the app layer.”
