In a decisive move to protect the technical architects of the digital asset economy, U.S. Senators Cynthia Lummis (R-Wyo.) and Ron Wyden (D-Ore.) have introduced the Blockchain Regulatory Certainty Act (BRCA). The standalone legislation, unveiled on Monday, Jan. 12, aims to settle a fierce, years-long debate: whether writing code makes a software developer liable as a financial institution.
The proposal comes at a critical juncture, with Congress racing to finalize a sweeping market structure bill in early 2026. As the Senate Banking Committee gears up for a markup later this month, the BRCA seeks to ensure that the individuals building the rails of the future financial system are not prosecuted for the actions of those who use them.
The “Developer as Bank” Dilemma
The BRCA’s primary objective is to define and separate custody from code, both for regulator and consumer alike. Currently federal regulators have applied the same regulatory framework (money transmission laws) to the platform-level of a blockchain. This creates a difficult and extended liability for any blockchain developer; for instance, the developer of open-source software that has the potential to facilitate the transfer of value may be held liable as a money transmitter under the existing regulatory structure, thereby making the developer liable for any actions of a customer or third party related to the software.
The BRCA also seeks to eliminate this ambiguity and the regulatory confusion created by the inconsistent application of money transmission laws through the establishment of a “safe harbor.” Under the proposed rules, if a developer, miner, or validator does not physically take custody of customer funds, they cannot be classified as a money transmitter.
“Forcing developers who write code to follow the same rules as exchanges or brokers is technologically illiterate and a recipe for violating Americans’ privacy and free speech rights,” Senator Wyden said in a statement. Senator Lummis echoed this sentiment, arguing that the current “developer as bank” narrative “makes no sense when they never touch, control, or have access to user funds.”
A Legislative Safety Net
The bill provides specific protections for the “plumbers” of the crypto ecosystem. It clarifies that non-custodial software developers, wallet providers who do not hold private keys, and miners who secure the network are strictly infrastructure providers—not financial intermediaries.
The difference made by this distinction will determine whether or not Decentralized Finance (DeFi) will survive in the United States. Without this distinction, simply publishing code for use as a self-custody wallet (and thus allowing individuals to create their own DEX) may create a requirement to register as a money services business (MSB) with the Financial Crimes Enforcement Network (FinCEN). This creates an impossible compliance burden on decentralized protocols.
The Tornado Cash Precedent
The pressing need for this legislation is attributed to increased legal scrutiny, particularly through the successful prosecution of several notable individuals within the cryptocurrency field over the past several years.The cryptocurrency industry remains shaken by the legal woes of Tornado Cash’s two primary software architects, Roman Storm and Alexey Pertsev; Prosecutors claim that both Storm and Pertsev created software which provides anonymity for users, thus establishing liability for any funds transferred into and out of Tornado Cash, despite neither of them possessing the ability to determine what happened with those funds. As a result, many developers now fear the ramifications of writing open-source code will turn into criminal prosecution.The BRCA is a direct response to the current “regulatory by enforcement” methodology being utilized in the U.S. with respect to the cryptocurrency industry and offer protection for developers via statute against continued criminal prosecutions relating to open-source software development.
Industry Rallies Behind the Bill
Crypto advocacy groups have wasted no time in throwing their weight behind the proposal. The DeFi Education Fund described the bill as providing “critical protections for software developers of non-custodial, decentralized technologies,” urging its inclusion in the broader market structure package.
Similarly, the Blockchain Association stated that clear rules are essential to prevent American innovation from fleeing overseas. Alexander Grieve, Vice President of Government Affairs at Paradigm, took to X (formerly Twitter) to call the bill “crucial legislation to support US blockchain development.”
The Race for Regulatory Clarity
The introduction of the BRCA is just one piece of a larger puzzle. The Senate Banking Committee is expected to mark up a broader crypto market structure bill on Thursday, Jan. 15, which reportedly includes similar protections for developers. At the same time, In an effort to create bipartisan Coalition, the Senate Agriculture Committee has delayed their Hearing until the week beginning on the last day of January.
Multiple pieces of legislation will be considered at the Same Time, and January 2026, will serve as An Important Milestone In Developing U.S. Digital Asset Policy. If Passed, This Framework Provides The Most Significant Update to Financial Regulations in Over 30 Years and Positions the United States to Be the Leading Destination for the Development of The Next Generation of Internet Technologies.
