Solana-based decentralized exchange Adrena has announced it will enter maintenance mode, ceasing the development of new features. Despite this shift, the core components of the protocol, including liquidity pools, staking, unlocking, and data systems, will remain operational. The team plans to open-source both the front-end and back-end code for community use. Adrena, established three years ago, achieved an annual trading volume of $8 billion and generated $10 million in fee revenue. The decision to halt active development was attributed to challenges in securing funding, retaining users, and intense market competition.
