Bluefin

Bluefin is the leading perpetual DEX on the Sui blockchain, running a fully on-chain orderbook optimized for Sui's parallel execution architecture. Launched in January 2024, it serves as the primary venue for leveraged trading within the growing Sui ecosystem.

The platform offers 7 markets with up to 20x leverage, charging 0.01% maker and 0.035% taker fees. While the market selection is limited compared to larger platforms, Bluefin benefits from being the dominant perp venue on Sui, capturing the majority of derivative trading volume on the chain.

Sui's object-oriented blockchain model enables parallel transaction processing, which Bluefin leverages for efficient orderbook operations. The protocol is focused on expanding alongside Sui's ecosystem growth, positioning itself as the default destination for Sui-native perpetual trading.

The BLUE token launched in December 2024 with a 20% community allocation (19.68% specifically for airdrops). The Trade & Earn program distributes BLUE rewards to active traders. As one of the first major DeFi protocols on Sui, Bluefin benefits from the chain's growing developer activity and user base.

Bluefin is the natural choice for Sui ecosystem participants who want to trade perpetual futures without bridging to other chains. Its first-mover advantage on Sui and tight integration with the chain's unique architecture give it a structural moat within the ecosystem.
