Sei is a Layer 1 blockchain specifically optimized for trading and exchange applications. Originally built on the Cosmos SDK, Sei has evolved into a parallelized EVM chain that combines the speed advantages of Solana-style parallel execution with Ethereum ecosystem compatibility. The blockchain features a built-in order matching engine, optimistic parallelization, and SeiDB for efficient state management. Sei V2 introduced parallel EVM execution, allowing it to process multiple independent transactions simultaneously while maintaining full EVM compatibility. This makes it one of the fastest EVM-compatible chains, targeting sub-second finality. The platform is designed to be the preferred chain for DeFi, particularly for order-book-based exchanges, derivatives platforms, and high-frequency trading applications. The ecosystem includes DEXes, perpetual exchanges, lending protocols, and NFT marketplaces optimized for the chain's high-performance capabilities.

DeFi

Sei is purpose-built for DeFi with native order matching capabilities, making it ideal for DEXes, perpetual exchanges, and other trading-focused decentralized applications.

EVM Blockchains

Sei V2 is fully EVM-compatible with parallel execution, enabling standard Solidity smart contracts to run with significantly higher throughput than traditional EVM chains.
