Aave founder Stani Kulechov has criticized proposed restrictions under the EU's MiCA framework, warning that new regulatory measures could hinder access to open financial networks. Kulechov expressed disappointment with consultation responses from the European Central Bank and the European Banking Authority regarding DeFi oversight. The proposed regulations include appropriateness tests for DeFi access and a potential certification regime for lending protocols. Kulechov argues these measures risk creating a "walled garden" effect that would limit user participation in decentralized finance ecosystems rather than fostering open innovation.
