Although framed as a regulatory advisory submitted to the U.S. Treasury Department on November 4, 2025, the a16z letter functions as a concentrated lobbying strategy that simultaneously articulates technical distinctions and signals preparedness to confront litigation risks, positioning decentralized stablecoins outside the GENIUS Act’s intended perimeter while seeking formal clarity from Treasury Secretary Scott Bessent. The submission, addressed directly to the Secretary, systematically argues that decentralized stablecoins operate through algorithmic and smart-contract mechanisms without a controlling legal person, thereby differentiating them from payment stablecoins subject to the GENIUS Act’s licensing regime, and it anchors this distinction in demonstrable architectural features exemplified by Ethereum-collateralized LUSD and other non-custodial issuance models. These self-executing agreements, known as smart contracts, automate protocol functions without intermediaries, underscoring the fundamental difference from centralized systems. In advocating for an exemption from the GENIUS Act scope, the document recommends adoption of the decentralized control framework derived from the Digital Asset Markets Clarity Act of 2025, proposing narrowly tailored exemptions for transaction verification, node operation, and non-custodial wallet development, measures designed to preserve market access for protocol engineers while constraining regulatory reach to activities involving centralized custodial vectors. The advisory advances privacy-preserving compliance mechanisms, urging FinCEN recognition of zero-knowledge proofs and multi-party computation as viable non-documentary identity verification modalities, and it frames decentralized digital identities as instruments that reconcile anti-money-laundering objectives with constitutional privacy protections, thereby reducing reliance on centralized databases and attendant cyber risk. Empirical assertions accompany normative prescriptions, with a16z citing on-chain analytics indicating under 1% illicit transaction incidence to support technology-driven alternatives to broad surveillance, and it contends that reusable decentralized identities can lower institutional compliance costs while maintaining effectiveness in financial-crime prevention. The letter situates its recommendations within the GENIUS Act’s implementation timeline, noting the statute’s delayed effective date pending final regulations, and it emphasizes the need for interagency coordination to prevent regulatory arbitrage, protect innovation, and safeguard competitive neutrality across asset classes, all articulated in a manner that signals industry readiness to litigate definitional disputes if administrative or statutory interpretations constrict non-custodial protocol development. The submission also explicitly requested that Treasury exclude decentralized stablecoins from the GENIUS Act’s licensing requirements. A16z additionally highlighted a core request seeking clarification on whether decentralized stablecoins fall within the GENIUS Act’s scope.
