About Sei

Sei is a Layer 1 blockchain optimized specifically for trading and DeFi applications. Built using the Cosmos SDK with a custom Twin-Turbo consensus, Sei claims to be the fastest blockchain to finality. The network features a built-in central limit order book (CLOB), parallelized EVM execution, and optimistic processing for high-speed trading. Sei V2 introduced EVM compatibility alongside its existing CosmWasm support, enabling both Solidity and Rust smart contracts on the same chain.
