The intersection of decentralized finance and federal oversight reached a critical juncture as cryptocurrency policy advocates formally weighed in on proposed federal rulemaking. Coin Center, a prominent independent nonprofit research and advocacy organization specializing in the public policy issues surrounding cryptocurrencies like Bitcoin and Ethereum, has submitted comprehensive comments to the United States Department of the Treasury regarding the implementation of the GENIUS Act. Filed under docket number TREAS-DO-2026-0496, the formal response addresses the regulatory framework governing payment stablecoin issuance, offer, and sale, raising alarms over potential legal ambiguities that could inadvertently criminalize routine, decentralized network operations.
At the core of Coin Center’s critique is proposed § 1523.2(d), a regulation designed to implement the GENIUS Act’s strict limitations on who may legally issue payment stablecoins within the United States. Under the statutory framework of the GENIUS Act, it is unlawful for any entity other than a permitted payment stablecoin issuer (PPSI) to issue a payment stablecoin domestically, with knowing participation in a violation carrying severe criminal penalties. While the Treasury Department has sought to deter circumvention by outlining a non-exhaustive list of activities that constitute participation in an unlawful issuance, Coin Center argues that the current drafting sweeps far too broadly, threatening open-source developers, node operators, and decentralized liquidity providers with felony-level exposure simply for engaging in standard blockchain protocol activities.
Background Context and the Legislative Framework of the GENIUS Act
The debate stems from the rapid evolution and mainstream integration of digital assets, particularly stablecoins—cryptocurrencies whose values are pegged to traditional fiat currencies, most notably the U.S. dollar. As stablecoins grew from niche trading instruments into foundational pillars of global crypto liquidity and cross-border settlement, federal regulators and lawmakers intensified scrutiny over their issuance, reserve backing, and systemic risk profiles. This legislative push culminated in the enactment of the GENIUS Act, a comprehensive statute aimed at bringing payment stablecoins under a centralized federal regulatory perimeter.
The statute explicitly restricts stablecoin issuance to PPSIs, establishing stringent licensing, reserve, and redemption requirements. To prevent evasion, Congress and regulatory bodies sought to penalize individuals and entities that assist unauthorized issuers. However, the legislation also explicitly recognized the unique architecture of open, public blockchain networks. Specifically, 12 U.S.C. § 5901(7)(B) carved out definitions excluding certain decentralized network functions—such as transaction validation, distributed ledger operation, and liquidity pool participation—from the classification of digital asset service providers (DASPs).
Despite these statutory guardrails, the Treasury’s proposed rule under § 1523.2(d)(2) and (3) introduced ambiguous criteria for what constitutes "coordination" or "market making" in connection with an unlawful issuance. According to Coin Center’s research director, Lizandro Pieper, the lack of precise statutory boundaries in the proposed text risks conflating malicious evasion with entirely independent, decentralized technical operations.
Decoding the Ambiguities in Proposed § 1523.2(d)(2)
The first major point of contention centers on proposed § 1523.2(d)(2), which targets individuals or entities that "coordinate with the issuer to facilitate key steps in the issuance, such as soliciting customers or minting the payment stablecoins." While acknowledging the Treasury’s legitimate objective to prevent bad actors from outsourcing illegal minting operations to third parties, Coin Center warns that the term "coordinates" remains dangerously undefined.
In a decentralized network environment, an issuance transaction must be processed, verified, and recorded by independent participants who have no relationship, communication, or agreement with the token issuer. Under proof-of-stake or proof-of-work consensus mechanisms, these participants include block builders who bundle transactions into blocks, block proposers, and network validators or relay nodes that attest to the validity of the ledger state.
Although the underlying statute requires a person to "knowingly participate" in a violation to incur criminal liability, Coin Center emphasizes that a node operator or validator may knowingly process a transaction containing an unauthorized stablecoin issuance without having any knowledge that the issuance itself violates the law, and certainly without "coordinating" with the issuer in any traditional legal sense. Without a strict, narrow definition that requires a explicit agreement and a purposeful intent to assist an unlawful issuance, routine validators could face legal jeopardy. To resolve this, Coin Center has formally proposed adding language to the final rule clarifying that coordination requires a bilateral agreement explicitly aimed at facilitating the illegal issuance, thereby insulating routine network activities from prosecution.
Addressing Secondary Market Trading and Market Making Under § 1523.2(d)(3)
The second significant area of concern involves proposed § 1523.2(d)(3), which penalizes anyone who acts as a market maker, distributes newly issued stablecoins to purchasers, or otherwise makes them available for secondary market trading. The Treasury’s internal preamble suggests this provision is intended to target "substantial assistance" provided close in time to the initial distribution. However, the actual regulatory text lacks these vital temporal and relational boundaries.
In modern decentralized finance (DeFi), market liquidity is frequently supplied through automated market makers (AMMs) and liquidity pools hosted on permissionless smart contracts. An independent developer or liquidity provider anywhere in the world can create an AMM pool and supply a newly issued token as liquidity moments after its creation, entirely without the issuer’s knowledge, consent, or cooperation.
Under the literal text of the proposed rule, such an independent actor could be prosecuted for participating in an unlawful issuance simply because their liquidity pool facilitated secondary market trading shortly after the token was minted. Coin Center argues that temporal proximity alone should never transform independent secondary market activity into a criminal conspiracy. The advocacy group has urged the Treasury to codify its preamble intent, restricting liability to situations where a market participant acts pursuant to an explicit agreement with the issuer for the purpose of providing substantial assistance to an initial unlawful distribution.
Evaluating the Definition of Issuer and Exempt Transactions
Beyond the participation provisions, Coin Center’s commentary addressed broader structural definitions within the proposed rulemaking. Responding to Treasury inquiries regarding the definition of an "issuer" (Question 23), Coin Center endorsed the current two-pronged approach, which requires both a redemption obligation and a representation or reasonable expectation of stable value. The organization strongly cautioned against making the technical act of "minting" an independently sufficient basis for issuer status. Because minting is frequently executed via automated smart contracts by third-party developers or network participants who bear no liability or relationship to the token’s backing, treating minting alone as issuance would unfairly criminalize software development.
Furthermore, Coin Center expressed strong support for the Treasury’s implementation of exempt transactions under proposed § 1523.4(c), which faithfully translates statutory exclusions outlined in 12 U.S.C. § 5902(h)(1). Concluding that these specific exemptions are clear and comprehensive, Coin Center recommended retaining the section without amendment.
Broader Implications for the U.S. Cryptocurrency Ecosystem
The outcome of this rulemaking process carries profound implications for the trajectory of blockchain innovation within the United States. Industry analysts and legal scholars note that overly aggressive enforcement interpretations could drive core developers, node operators, and liquidity providers offshore, severely undermining the domestic blockchain infrastructure.
By drawing a sharp legal distinction between deliberate, conspiratorial assistance in illegal financial schemes and routine, automated technical participation in open-source networks, Coin Center’s recommendations seek to strike a constitutional and economic balance. As the Department of the Treasury reviews public comments under docket TREAS-DO-2026-0496, the agency faces the delicate task of balancing systemic financial risk mitigation against the preservation of permissionless technological innovation. The final text of the rules, expected later in the year, will serve as a definitive benchmark for how federal regulators intend to police the boundaries of decentralized finance in the digital age.
