DEX in the City: Why the Market Structure Bill May Not Be Good for DeFi
Thank you to our sponsor, Mantle!
After months of anticipation, U.S. Senators have unveiled draft crypto market structure legislation.
In this episode of DEX in the City, hosts Jessi Brooks, Katherine Kirkpatrick Bos and Vy Le are joined by Blockchain Association CEO and former CFTC Commissioner Summer Mersinger to unpack all the provisions that stand out.
These include the bill's attempt to draw a line between centralized and decentralized platforms, the amended stance on stablecoin yield and exemptions for assets with ETFs.
Would the bill “sweep up all of DeFi?” Has crypto lost the fight over stablecoin yield? And is Trump playing interference for crypto?
