Andreessen Horowitz, better known as a16z, and the DeFi Education Fund are calling on the U.S. Securities and Exchange Commission to introduce a regulatory safe harbor for decentralized applications. They sent a detailed letter to SEC Commissioner Hester Peirce asking for clearer rules that would stop certain dApps from being lumped in with broker-dealers.
Their main argument is simple: not all apps that touch crypto are trying to be financial middlemen. Some are just tools that let users interact with smart contracts. If a dApp doesn’t hold funds, provide investment advice, or interfere with transactions, the groups say it shouldn’t fall under brokerage rules.

The letter outlines four clear criteria a dApp would need to meet to qualify. It must run on decentralized protocols, be non-custodial, avoid giving investment tips, and leave full control in the hands of the user. In other words, treat it like a tool if it acts like one, not a financial service.

This push didn’t come out of nowhere. Developers in the DeFi space have been growing increasingly anxious about enforcement actions. A recent case involving a Tornado Cash developer being hit with money transmitter charges has sent a warning across the industry. Builders are now worried they could get caught up in regulations aimed at bad actors, even when they’re not providing any financial service at all.
A16z has made similar requests in the past. They’ve previously asked the SEC for safe harbors covering things like airdrops, token launches, and even NFTs. This time, the focus is strictly on user-facing apps. These apps allow people to tap into smart contracts without giving up control. The goal is to keep unclear or outdated rules from driving innovation offshore.

One of the big arguments behind this proposal is that clarity helps everyone. Developers can focus on building, regulators can target real threats, and users benefit from more secure and useful tools. Without these safe harbors, smaller teams might fold or leave the country entirely to avoid legal risk.
If the SEC chooses to act on this proposal, it might give the U.S. a chance to lead the way in defining how decentralized apps are treated. Other countries could use the same principles as a starting point. But for now, everything hinges on whether the SEC is ready to distinguish between infrastructure and intermediaries.
This is not just about DeFi apps. It’s about how the rules get applied to software in a world where anyone can write code that interacts with money. The SEC has a choice to make: either treat developers like they’re running banks, or recognize that sometimes, they’re just writing tools.
