The MIT Digital Currency Initiative (DCI) published a critique of the recently passed GENIUS Act, the first U.S. federal law regulating payment stablecoins. While the Act establishes redemption requirements and sets a framework for compliance, it leaves unresolved issues around maintaining stablecoin value in secondary markets, technical interoperability, and regulatory standards for security and smart contracts. The law prohibits issuers from paying interest and introduces ambiguities in its scope—especially regarding new stablecoin models and decentralized systems. Ultimately, although the GENIUS Act represents a major policy advance, unresolved policy, technical, and regulatory questions may impact both users and the future growth of stablecoins in the U.S. [Source: MIT DCI]
