DeFi public chain Katana announced adjustments to its KAT token economic model, terminating the vKAT staking and voting incentive mechanism on November 17th and instead distributing protocol revenue to stakers through avKAT. Katana has integrated three acquired assets, including Sushi's DEX deployment on Katana, the decentralized exchange IDEX, and the yield infrastructure Vault Bridge. The new mechanism will extract a portion of revenue from its four main business segments—spot trading, perpetual contracts, Vault Bridge, and the sorter—to repurchase KAT on the open market, distributing all repurchased tokens to avKAT stakers. Furthermore, the staking exit cooldown period will be shortened from 45 days to 7 days, and a fully automated on-chain repurchase mechanism will be launched later. https://wublock123.com/news/news-71804
