Uniswap is attempting an experiment that could potentially alter the DeFi compliance landscape. On August 12th, the Uniswap Foundation proposed to register governance as DUNA (Decentralized Non Corporate Non Profit Association) in Wyoming and establish a legal entity called "DUNI" to pave the way for future activation of the agreement fee mechanism. DUNA is a legal structure designed specifically for DAOs in Wyoming, which retains the essence of decentralized governance while providing limited liability protection to prevent unregistered DAOs from being treated as general partnerships and members from assuming unlimited liability. DUNI is able to legally sign contracts, hold assets, hire service agencies, and assume tax obligations, which means Uniswap can collaborate with traditional agencies to expand its ecosystem in a compliant manner. The protocol fee mechanism is a deeper focus of change. The current transaction rate is 0.3%, all of which belong to LP; If the cost switch is turned on, 0.05% of it will go to the DAO treasury for funding development, security, incentives, etc., indirectly increasing the value of UNI. DUNA provides a legal basis for this fee, but the reduction of LP revenue may trigger a "negative flywheel effect" such as liquidity withdrawal, sliding point increase, and trading volume decline, which damages Uniswap's core advantages. The market response has been positive, with UNI rising by over 8% at one point. Supporters believe this is a crucial step for the long-term development of the agreement; Opponents are concerned about centralization risks, timing of cost mechanisms, and cross-border compliance challenges. This compliance breakthrough around DUNA tests Uniswap's ability to balance "value capture" and "liquidity competitiveness", and provides a new institutionalized and legalized sample for the entire DeFi.
