The U.S. debate over crypto market structure is moving into a critical phase, and open-source developers are becoming one of the most important issues in the discussion. Solana Institute CEO Kristin Smith is urging the Senate to pass the CLARITY Act with strong protections for developers, validators, and blockchain infrastructure providers, arguing that they should not be regulated as financial intermediaries when they do not control user funds or execute transactions.
Her message comes as the CLARITY crypto market structure bill moves closer to a possible Senate floor vote later this summer. The bill has already cleared the Senate Banking Committee and has been placed on the Senate Legislative Calendar, giving the industry a clearer path toward one of the most consequential pieces of digital asset legislation in the United States.
Smith’s argument is straightforward: writing open-source software is not the same as operating a brokerage, exchange, custodian, or money transmission business. Developers who publish code, validators who support network operations, and non-custodial wallet providers that do not control assets should not be treated as if they are holding customer funds or executing financial transactions on behalf of users.
The issue matters because many blockchain systems depend on open-source development. If developers face unclear or overly broad regulatory risk, the U.S. could discourage technical innovation, push builders offshore, and weaken the domestic crypto infrastructure ecosystem. If Congress creates clear protections, the industry could gain a more stable legal environment without removing oversight from actual financial intermediaries.
Why Developer Protections Matter
Crypto regulation often focuses on exchanges, token issuers, brokers, custodians, and market manipulation. Those areas are important because they involve customer assets, trading venues, disclosures, and investor protection. But open-source developers occupy a different role.
A developer may write software that allows a blockchain protocol, wallet, decentralized application, or validator system to function. In many cases, that developer does not custody assets, control a user’s private keys, choose who transacts, approve transfers, or profit from handling customer funds. The code can be used by others, but publishing software is not the same as directly providing a regulated financial service.
That distinction is at the heart of the current debate. Industry advocates argue that if developers are treated like brokers or money transmitters simply because their code can be used for financial activity, the legal risk becomes too broad. Developers may avoid contributing to open-source blockchain projects, even when they have no control over user behavior.
For an industry built on shared infrastructure, that could have large consequences. Blockchains need protocol developers, security researchers, wallet builders, node operators, validators, and infrastructure providers. If these participants face the same compliance burden as custodial platforms, smaller teams may be unable to operate in the United States.
Kristin Smith’s Message to the Senate
Kristin Smith said the market structure legislation has a real chance of passing the Senate, which makes the developer-protection language especially important. Her view is that Congress should preserve the parts of the bill that separate noncontrolling technology providers from financial intermediaries.
Smith also said more than 60 crypto CEOs and founders signed an open letter urging the Senate to maintain robust protections for developers in the CLARITY Act. Solana co-founder Anatoly Yakovenko was among the signers, reflecting how important the issue has become for major blockchain ecosystems.
The core argument is that open-source developers, validators, and non-custodial wallet providers do not control user funds or execute user transactions. Therefore, they should not be treated as brokers, custodians, or other regulated intermediaries.
This does not mean the industry is asking for no rules. Instead, the position is that regulation should be targeted at the entities that actually handle customer assets, provide trading services, or control transaction execution. A centralized exchange should face different obligations than a developer who publishes code. A custodian should face different obligations than a validator that supports network consensus without taking possession of customer property.
The CLARITY Act is designed to create a clearer market structure framework for digital assets in the United States. For years, the crypto industry has argued that uncertainty between agencies, especially the Securities and Exchange Commission and the Commodity Futures Trading Commission, has made compliance difficult.
Market structure legislation could define which assets fall under which regulatory regime, what obligations apply to intermediaries, and how digital asset platforms should operate. The goal is to reduce uncertainty while still giving regulators tools to protect users and markets.
Developer protections are one part of that broader framework. Without them, the bill could still leave a major source of uncertainty unresolved. Even if exchanges and issuers receive clearer rules, software builders may remain exposed if the law does not clearly separate code publication from financial intermediation.
That is why the current Senate debate matters. The final language could shape whether the United States becomes a more attractive environment for blockchain infrastructure development or continues to push technical contributors toward jurisdictions with clearer rules.
The Blockchain Regulatory Certainty Act
Smith pointed to the Blockchain Regulatory Certainty Act, or BRCA, as a model for legal clarity. Introduced in January by Senators Cynthia Lummis and Ron Wyden, the bipartisan bill aims to protect noncontrolling software developers and blockchain infrastructure providers from being classified as money transmitters solely for publishing software code.
The BRCA focuses on a key principle: control. If a person or company does not custody customer assets and does not control transactions, it should not be treated as a money transmitter simply because it creates or supports technology that others use.
This distinction is important for non-custodial wallets, validators, miners, node operators, protocol developers, and other infrastructure participants. These actors can help maintain blockchain networks without directly managing customer funds.
For example, a non-custodial wallet provider may create software that lets users hold their own private keys. The provider does not possess the assets and cannot move funds without the user. Treating such a provider like a custodian would blur a critical technical and legal distinction.
The BRCA attempts to prevent that outcome by creating certainty for builders who do not control assets or transactions. Smith’s comments suggest that similar protections should remain in the CLARITY Act.
Hester Peirce Echoes the Same Concern
Smith’s position aligns with recent comments from SEC Commissioner Hester Peirce. Peirce argued that publishing open-source blockchain code is generally protected activity and that developers should not be treated as financial intermediaries simply because others use their software.
Her comments are significant because they come from inside the SEC, an agency that has played a central role in crypto enforcement. Peirce has long argued for clearer rules and a less enforcement-driven approach to digital asset regulation.
The First Amendment issue adds another layer to the debate. If publishing code is treated as speech, then regulating developers as financial intermediaries merely because they release open-source software could raise constitutional concerns. The question becomes whether regulators are targeting actual financial activity or indirectly restricting software publication.
Peirce’s view supports a narrower regulatory approach: focus on those who custody assets, operate markets, commit fraud, mislead investors, or control financial activity, rather than developers who write and publish neutral technology.
A Shift Away From Regulation by Enforcement
The SEC’s approach to digital assets has reportedly shifted under Chair Paul Atkins, who has pledged to move away from “regulation through enforcement.” That phrase refers to a regulatory style in which agencies define industry obligations mainly through lawsuits and enforcement actions rather than clear rules.
For many crypto companies, regulation through enforcement created a difficult operating environment. Firms often complained that they could not know which activities were permitted until after an enforcement action was filed. Developers, in particular, faced uncertainty because they were not always sure whether publishing software could expose them to financial regulatory liability.
A legislative framework like the CLARITY Act could reduce that uncertainty. If Congress defines the boundaries clearly, companies and developers can make better decisions before launching products or contributing to protocols.
However, the shift will depend on the details. A market structure bill that protects developers while regulating actual intermediaries could create a more balanced regime. A bill that leaves developers exposed could preserve much of the uncertainty the industry wants to resolve.
Why Solana and Other Layer-1 Ecosystems Care
Layer-1 blockchain ecosystems such as Solana depend heavily on developers and infrastructure operators. Their value does not come only from the native token price. It comes from network activity, application development, validator participation, tooling, wallets, and user adoption.
If open-source contributors face unclear liability, the entire ecosystem can slow down. Developers may avoid building core tools, wallet providers may limit features, validators may face compliance questions, and infrastructure firms may move operations outside the United States.
Solana has positioned itself as a high-performance blockchain for consumer applications, decentralized finance, payments, gaming, and infrastructure. That makes developer participation especially important. A network that wants fast application growth needs a legal environment where builders can contribute without being treated as financial intermediaries by default.
This is not only a Solana issue. Ethereum, Bitcoin, Cosmos, Avalanche, and other ecosystems all depend on open-source development. But Solana’s public advocacy through the Solana Institute shows how seriously major networks are taking the Senate debate.
The Difference Between Infrastructure and Intermediation
The most important policy question is how to distinguish infrastructure from intermediation. In traditional finance, intermediaries often hold assets, execute trades, route orders, manage accounts, or process payments. They are regulated because they stand between customers and financial activity.
Blockchain networks can work differently. A validator may help confirm transactions but may not know the parties or control their assets. A wallet developer may create software, but the user may hold the keys. A protocol developer may write code, but the network may operate without that developer’s ongoing control.
If the law treats all these actors as intermediaries, it may misunderstand the architecture of decentralized systems. If the law treats none of them as responsible under any circumstances, it could create gaps in consumer protection. The challenge is to draw a precise line.
Developer protections try to draw that line around control. If an actor controls user funds, executes transactions for customers, or operates a custodial service, regulation may apply. If the actor merely publishes code or provides infrastructure without control, it should not be treated the same way.
Potential Impact on U.S. Crypto Innovation
If developer protections remain intact, the CLARITY Act could improve the United States’ position in blockchain innovation. Developers would have more confidence contributing to open-source projects. Infrastructure firms could operate with clearer boundaries. Investors could better assess legal risk across crypto ecosystems.
This could also help keep technical talent in the United States. Regulatory uncertainty has been one reason some crypto teams choose to build abroad. Clear rules would not eliminate all risk, but they could reduce fear that ordinary software development will be treated as regulated financial activity.
The impact could extend beyond crypto trading. Blockchain infrastructure is used in payments, identity systems, supply chain tracking, tokenization, stablecoins, decentralized applications, and data coordination. Developer protections could support these areas by making it easier to build neutral tools.
For investors, the issue is indirect but important. Stronger legal clarity can support network development, application growth, and institutional participation. Weak clarity can slow adoption, raise compliance costs, and reduce the appeal of U.S.-based blockchain projects.
Not everyone will agree with broad developer protections. Critics may argue that some developers retain influence over protocols, profit from token launches, or design systems that enable harmful activity. Regulators may worry that overly broad exemptions could allow some actors to avoid accountability by claiming to be mere technology providers.
That concern is not irrelevant. Some blockchain projects are highly decentralized, while others rely heavily on core teams, foundations, or companies. A legal framework must account for differences in control, profit, governance, and user reliance.
The policy challenge is to avoid two extremes. One extreme is treating every developer as a financial intermediary. That could chill open-source innovation. The other extreme is giving blanket immunity to any actor who claims to publish code. That could weaken consumer protection.
A balanced framework would protect genuinely noncontrolling developers while preserving enforcement authority over fraud, custody, market manipulation, and entities that actually control financial services.
What Investors Should Watch Next
Investors should first watch the Senate timeline for the CLARITY Act. Placement on the Legislative Calendar means the bill has moved closer to a possible floor vote, but the final timing and amendments remain important.
The second issue is whether developer protections survive the legislative process. Changes to the language could alter the impact of the bill significantly.
The third factor is how the CLARITY Act interacts with the BRCA. If the final framework includes clear principles around control, custody, and transaction execution, infrastructure providers may receive stronger legal certainty.
The fourth point is the response from regulators. Even if Congress passes market structure legislation, agencies will still need to implement rules and guidance. The SEC, CFTC, Treasury, and state regulators could all influence how the law works in practice.
Finally, investors should watch how major blockchain ecosystems respond. Solana, Ethereum, and other networks may increase U.S.-based development activity if the legal environment becomes clearer.
The CLARITY Act has become a major test for U.S. crypto regulation, and developer protections are now one of its most important battlegrounds. Solana Institute CEO Kristin Smith is urging the Senate to preserve language that shields open-source developers, validators, and non-custodial wallet providers from being treated as financial intermediaries when they do not control user funds or execute transactions.
Her position reflects a broader industry concern: the United States needs rules for crypto markets, but those rules must distinguish between financial intermediaries and neutral technology builders. Treating code publishers like brokers or custodians could damage open-source development and push innovation offshore.
The Senate’s handling of developer protections may shape the next phase of U.S. crypto policy. If the CLARITY Act protects noncontrolling builders while regulating actual intermediaries, it could create a more practical framework for blockchain innovation. If those protections are weakened, legal uncertainty for open-source crypto development could remain one of the industry’s biggest obstacles.
