This operation with UNI has indeed played a big hand. The fee switch is finally going to be turned on, and it directly retroactively destroyed 100 million tokens. Various empowerment details are fully loaded, and the market clearly did not expect such a strong move, causing the coin price to directly rise over 40%.

Let's talk about how this fee mechanism works: The fees generated by the protocol will first enter a contract pool called TokenJar, where they can only go in and not come out. The only exit? Someone has to go to the Firepit contract to burn a certain amount of UNI. After this combination of actions, the actual effect is to use the protocol's income to buy back and burn tokens, directly benefiting the token holders.

This design that directly feeds the value of the protocol back to the Token is a good start in DeFi. However, whether it can be sustained will depend on the degree of cooperation in subsequent execution and community governance.
