Bluefin is a decentralized exchange (DEX) built on the Sui blockchain, offering derivatives and spot trading through an order book model. It aims to provide a high-performance, scalable, and secure trading experience, combining the benefits of decentralized finance with the efficiency of traditional exchanges. Bluefin supports leveraged trading, concentrated liquidity pools (CLMM), and integration with Web3 wallets and Google accounts. Its native token, BLUE, is used for governance, rewards, and liquidity incentives. The platform is backed by major investors, including Polychain, Susquehanna, and Brevan Howard Digital. Founded by Rabeel Jawaid and Ahmad Jawaid, Bluefin has undergone audits by Trail of Bits, PeckShield, and Halborn to ensure security. The protocol features a DAO-driven governance model, an insurance fund, and ongoing reward programs for traders and liquidity providers, reinforcing its role in the Sui ecosystem.
