When building blockchains, we generally try to bucket them into two distinct boxes: general purpose or app chain. General purpose chains for permissionless innovation and app chains for permissioned and specific use cases. Sei is an upcoming Cosmos chain aiming to be a “DeFi-optimized” layer 1. To be clear, Sei is not a DEX, it is a layer 1 optimized for DeFi. Not a “pure” app chain like THORChain that focuses solely on cross-chain swaps, but one that is built for applications like DEXs, perps, and options to build on top.
