ChainCatcher news, the U.S. cryptocurrency lobbying group (Blockchain Association) stated in a social media post that a lawsuit has been filed against the new "broker" regulations issued by the U.S. Internal Revenue Service and the Department of the Treasury.

The IRS and the Treasury have exceeded their legal authority by expanding the definition of "broker" to include providers at the front end of DeFi transactions, even though they do not execute trades. This not only violates the privacy rights of individuals using decentralized technology but also pushes emerging technologies overseas.
