Sea protocol is a decentralized exchange built on order-book and automated market maker mechanics for the Aptos and Sui blockchains.
The protocol addresses the need for fast, low-cost decentralized trading by leveraging the parallel processing capabilities of Aptos and Sui. Its core innovation is grid orders, a trading mechanism where buy and sell orders are placed at regular intervals across a price range. When a sell order fills, it automatically converts to a buy order at a lower price, and vice versa, allowing traders to profit from price fluctuations without manual intervention. The protocol also supports zero-spread trading, enabling post-only orders at identical prices on opposite sides, which is particularly useful for stablecoin pairs. Additionally, the protocol implements a "trading is mining" model where token rewards are distributed equally between traders and liquidity providers, rather than concentrating incentives on one group.
Developers building on Aptos or Sui who need a high-performance DEX infrastructure should consider this protocol. It suits projects requiring both order-book depth and AMM functionality, particularly those serving stablecoin trading or grid trading strategies. The protocol is written in Move, making it native to its target blockchains. The tool emphasizes accessibility and decentralization, positioning itself as infrastructure for unrestricted asset trading.
Development activity shows ongoing work on the core protocol with active community engagement through social channels and Discord. The project maintains documentation of its design principles and technical specifications, including detailed explanations of pricing mechanics and minimum lot size protections against Sybil attacks. The codebase reflects a focus on the specific capabilities of Aptos and Sui rather than cross-chain deployment, as evidenced by the separate EVM version being maintained under a different repository.
