Crypto Lobby to U.S. Senate: Don’t Kill DeFi Innovation

DeFi Leaders Urge U.S. Senate to Rethink Crypto Regulation Bill

The battle over how to regulate crypto in the U.S. just got more intense.

The DeFi Education Fund (DEF)—a major crypto policy group backed by heavyweights like a16z Crypto, Uniswap Labs, and Paradigm—has sent a strong message to the U.S. Senate: Don’t crush decentralized finance (DeFi) with outdated rules.

In a recent letter to lawmakers, DEF warned that the latest draft of the Responsible Financial Innovation Act of 2025 (RFA) could damage the growing DeFi sector if not revised to reflect how decentralized systems truly operate.

What Sparked the Backlash?

On Capitol Hill, lawmakers have been working on crypto legislation to bring structure to a fast-evolving space. The Senate Banking Committee released a discussion draft of a key market-structure bill aimed at improving consumer protection and stopping financial crime.

But crypto insiders say the draft misses the mark—especially when it comes to DeFi.

What the DeFi Education Fund Is Saying

 Defending DeFi Developers

The DeFi Education Fund wants the Senate to:

• Keep the bill tech-neutral so it doesn’t unfairly target decentralized systems.

• Protect self-custody rights—meaning individuals should have full control over their digital assets.

• Make sure crypto developers are not treated like traditional financial intermediaries.

• Update FinCEN guidance so that non-custodial software tools (like Tornado Cash) aren’t wrongfully labeled as financial institutions.

“Not all code is a bank,” DEF essentially argues. They want laws to distinguish between decentralized code and centralized platforms.

Why Tornado Cash Matters

The DEF letter highlights the Roman Storm/Tornado Cash case, in which a developer was prosecuted even though his software was open-source and non-custodial.

This case has raised red flags for the developer community, which now fears criminal charges just for publishing or contributing to privacy tools.

The DEF is demanding that any future crypto law clarifies the difference between developers and intermediaries—to avoid such legal overreach.

Call for Federal Clarity Over State Confusion

 One National Rulebook, Not 50

DEF also wants federal preemption—meaning national rules should override conflicting state laws. They argue that without this, developers face:

• A patchwork of regulations across states

• Risk of frivolous lawsuits

• Unfair targeting by traditional banks that fear competition from DeFi

“Wall Street could use messy state laws to shut us down under the disguise of ‘consumer protection,’” DEF warns.

What Does a16z Crypto Say?

A16z Crypto—part of the influential venture capital firm Andreessen Horowitz—filed its own response to the Senate draft. Their main concern? The bill may loosen the rules too much for some, while overregulating others.

 The Problem with “Ancillary Assets”

One part of the bill introduces the concept of “ancillary assets.” These are digital tokens that could be exempt from securities laws under certain conditions.

A16z says this term is too vague and might let:

• Insiders exploit loopholes

• Projects dump tokens on the public

• Regulators lose oversight

They argue this directly clashes with the Howey Test, the current legal benchmark used to decide whether an asset is a security.

 A Better Idea—The Digital Commodity Model

Instead of “ancillary assets,” a16z proposes a digital commodity framework. Under this model:

• Crypto tokens could be classified based on clear decentralization standards

• There would be a transparent path to compliance

• Investor protections would be preserved, not bypassed

What’s at Stake for the $141 Billion DeFi Market?

The DeFi industry is valued at over $141 billion, with platforms handling everything from lending and trading to stablecoins and privacy tools.

But if lawmakers get it wrong, it could:

• Drive innovation offshore

• Stifle U.S. developers

• Let big banks take over under restrictive or unfair laws

The DEF and a16z are both urging Congress to strike a balance—protect users without punishing the technology or those who build it.

Where Do Things Go From Here?

The Senate Banking Committee is still in feedback mode, collecting responses from industry players. The current bill is meant to complement another proposal, the Digital Asset Market Clarity Act of 2025, which also seeks to regulate digital assets while promoting innovation.

But based on the strong responses from DEF and a16z, it’s clear that major revisions are needed before the crypto industry is on board.

 Why This Fight Matters

This isn’t just about legal language or regulatory turf wars—this is about the future of DeFi in America.

The outcome of this debate will determine:

• Who gets to build in crypto

• Whether developers face legal risks for writing code

• How much freedom users have to control their digital assets

As lawmakers move closer to finalizing crypto regulations, voices like the DEF and a16z are making sure the people who actually build the future of finance are heard.
