Sei explores the middle of the extremes - not quite general purpose nor app-specific but DeFi-specific which enables the layer 1 to explore a brand new design space.

By exploring the new design space in between app-chains and general purpose L1s, Sei has carefully selected for a unique set of tradeoffs that make its layer 1 the optimal environment for DeFi apps. Designed from bottoms-up to scale with the needs of DeFi, Sei unlocks new possibilities with optimizations including:

1 - Built-in orderbook - solves the age-old orderbook scaling issue

2 - Frontrunning protection - MEV is a major drawback of popular chains like Ethereum and Solana

3 - Finality - Sei is the fastest chain to finality at ~600ms
