Sei (SEI) is a high-performance, Layer 1 blockchain designed to optimize decentralized finance (DeFi) applications and trading infrastructure. The project was created by a team of blockchain engineers and launched its mainnet in 2023, aiming to provide fast, efficient, and low-latency transaction execution for DeFi users and developers. Its architecture focuses on order matching, price oracle integration, and optimistic block execution, all built to enhance financial activity on-chain.
