Sei Network
Summary
Sei Network is a Layer 1 blockchain developed by Sei Labs, co-founded in 2021 by Jayendra Jog and Jeff Feng, designed to optimize high-throughput trading and DeFi with a parallelized EVM architecture. The project raised $35 million across seed and Series A rounds from prominent crypto VCs, launched its mainnet in August 2023, and has grown to over $600 million in TVL as of mid-2025. While no regulatory enforcement actions have been brought against Sei Labs or the Sei Foundation directly, the project faced community backlash over its 2023 airdrop distribution and carries structural risk concerns related to token unlock schedules, insider allocation concentration, and a low validator decentralization score.
