Decentralized exchange Raydium has announced the launch of its new feature 'Burn & Earn', aimed at enabling project teams to permanently lock the liquidity of Centralized Limit Market Maker (CLMM) while retaining the right to claim trading fees. This innovative move is mainly focused on the full range positions of CLMM, once locked, liquidity providers will not be able to withdraw or manage the position for rebalancing. However, users can still view the locked positions and claim fees and rewards on the portfolio page. By introducing the 'Burn & Earn' feature, Raydium aims to enhance its competitiveness in the decentralized finance space, providing more flexible and controllable liquidity management methods.
