The Solana Policy Institute has sent a letter to Senate leaders this week urging them to preserve protections for open-source developers and validators as Congress hammers out the CLARITY Act. The group, led by industry veteran Kristin Smith, warns that Section 604 of the bill could inadvertently classify neutral technology providers as financial intermediaries — a move that would stifle crypto development in the US. The lobbying effort comes as lawmakers debate language that could reshape how DeFi protocols, wallet providers, and layer-2 projects operate.
What's at stake in Section 604
At the heart of the dispute is how the CLARITY Act defines a broker or money transmitter. The Solana Policy Institute argues that if open-source developers, validators, or infrastructure providers are forced to register as regulated financial entities, it would hinder everything from Solana’s ecosystem to Ethereum, Bitcoin layer-2 networks, and beyond. The letter pushes for language that clearly distinguishes builders who just provide tech from businesses that actually custody assets or handle customer funds.
Who's behind the push
Kristin Smith, who leads the Solana Policy Institute, has been a frequent voice in Washington on crypto policy. The group’s letter is part of a broader lobbying blitz targeting Senate leaders before the bill moves further through the legislative process. The timing matters — unclear rules could freeze innovation at a moment when DeFi and validators are already navigating a patchwork of state-level regulations.
Why it's not just a Solana issue
Although the institute is Solana-focused, the implications ripple across the industry. Ethereum stakers, Bitcoin layer-2 developers, and wallet engineers all face the same potential headache if the final bill lumps neutral code providers with money transmitters. The letter makes clear that the problem isn't limited to one chain — it's about preserving the legal space for open-source software development itself.
What happens next
The Senate is expected to take up the CLARITY Act in committee over the coming weeks. The Solana Policy Institute’s letter is one of many competing interests lawmakers will weigh. For now, developers and validators are watching to see whether the final language draws the line the industry is asking for — or creates a new compliance burden that could push projects overseas.
