Over a hundred crypto companies have signed an open letter, requesting that the crypto market structural bill include DeFi protection provisions.

On August 27, according to crypto journalist Eleanor Terrett, over 110 crypto companies, investors, and advocacy groups signed a letter warning U.S. Senate Banking and Agriculture Committee leaders that they would not support the legislation on market structure unless it clearly protects open source software developers and non-custodial service providers. With support from heavyweight firms such as CEX, a16z crypto, Ripple, as well as top projects, investment companies, and state blockchain councils, the DeFi education fund warned that treating developers who release code or enable non-custodial blockchain access as financial intermediaries could hinder blockchain innovation in the United States. The coalition noted that according to a recent White House report on digital assets, the proportion of open source software developers in the U.S. has significantly declined from 25% in 2021 to 18% in 2025. While the coalition praised the House and Senate for incorporating some developer protections and the right to self-custody of digital assets in the current market structure draft, they believe it is not enough and are beginning to call for clear federal rules to protect DeFi developers, ensure national regulatory consistency, and maintain U.S. open source innovation.
