Decentralized exchange Raydium has announced the launch of a new feature "Burn & Earn" that allows project teams to permanently lock in the liquidity of Centralized Liquidity Market Makers (CLMMs) while retaining a claim on transaction fees. The new feature is primarily for CLMM full-range positions. Once locked, liquidity providers will not be able to withdraw or manage positions for rebalancing. However, users can still view locked positions and receive fees and rewards on the portfolio page.
