Decentralized exchange Trader Joe announced that Liquidity Book V2.2 has gone live. V2.2 introduces the peg function of Liquidity Book, and centralized incentives have been implemented. Centralized incentives specifically refer to LB pools equipped with local, real-time, and fully on-chain mechanisms to incentivize LPs. Each LB pool will have a reward range. Reward tokens are allocated to LPs according to the liquidity ratio. The reward range is anchored to active positions and moves in sync with the fixed range of 1 - 11 positions (maximum). The goal of LP is to keep liquidity within the reward range in order to maximize the incentive share. In addition, Trader Joe will launch the Arbitrum incentive tomorrow, and 755,000 ARB tokens will be distributed as incentives in about 30 liquidity pools.
