Sei Labs

Sei Labs builds Sei, a Layer 1 EVM-compatible blockchain designed for real-time, high-frequency Web3 applications. The chain is engineered around performance: it claims 400ms finality, throughput of 200,000 transactions per second, and ranks as the leading EVM chain by active users. To date, Sei has processed billions of transactions across more than 65 million wallets.

The primary use cases Sei targets - DeFi, gaming, and AI agents - share a common requirement for low latency and high throughput at scale. Sei Labs positions the chain as infrastructure capable of meeting Web2-level demand within a decentralized architecture, without trading off security for speed.

The engineering team draws on backgrounds from Robinhood, Nvidia, Google, Goldman Sachs, and Databricks. The technical domains span Layer 1 blockchain engineering, EVM compatibility, consensus and finality systems, and high-throughput transaction processing. The team works closely with ecosystem partners and operates with startup pace, prioritising impact over process.
