What is Sei?
Sei is a layer-1 blockchain built for high performance, using parallelized execution to process many transactions at once while staying compatible with Ethereum tooling. Its design targets fast trading and low fees, aiming to remove common bottlenecks in on-chain finance. The SEI token powers the network, used for fees, staking, and governance. The project has focused on speeding up execution so applications can run closer to the responsiveness of traditional web services. Its emphasis on throughput and Ethereum compatibility shapes its appeal to developers. You can follow the Sei price and hold SEI in a self-custody wallet.
