According to CoinMeta, the public chain Katana announced that it will terminate the staking and voting incentive mechanism on November 17th, and instead distribute protocol revenues to stakers through avKAT. Katana has integrated three acquired assets, including Sushi's deployment on Katana, the decentralized exchange IDEX, and the revenue infrastructure Vault Bridge. The new mechanism will extract funds from the revenues of spot trading, perpetual contracts, Vault Bridge, and sorters to repurchase KAT in the open market, and all the repurchased tokens will be distributed to the stakers of avKAT. In addition, the cooling-off period for staking withdrawal will be shortened from 45 days to 7 days, and a fully automated on-chain repurchase mechanism will be introduced later on.
