DeFi public chain Katana announced changes to its KAT tokenomics. On November 17, it will end vKAT staking and voting incentives, and instead distribute protocol revenue to stakers through avKAT. Katana has integrated three acquired assets: Sushi’s DEX deployment on Katana, decentralized exchange IDEX, and yield infrastructure Vault Bridge. Under the new mechanism, a portion of revenue from four business lines—spot trading, perpetual contracts, Vault Bridge, and the sequencer—will be used to buy back KAT on the open market, with all repurchased tokens distributed to avKAT stakers. In addition, the staking withdrawal cooldown will be reduced from 45 days to 7 days, and a fully automated on-chain buyback mechanism will be introduced later.
