By exploring the new design space in between app-chains and general purpose Layer 1's, Sei has carefully selected for a unique set of tradeoffs that make its Layer 1 an optimal environment for DeFi applications. They're unlocking new possibilities with a native order matching engine, frontrunning prevention, and major speed improvements.
