What is Sei?
Sei is a layer-1 blockchain built for fast trading applications, with sub-second finality and parallel transaction processing. Since its v2 upgrade it runs a parallelized EVM, so Ethereum-style smart contracts can be deployed on it. SEI pays gas fees, is staked to secure the proof-of-stake network, and is used in governance; the mainnet launched in August 2023.
