Sei v2 is a parallelized, EVM-compatible Layer 1 built using the Cosmos SDK with an embedded Geth engine. Designed for high-performance applications, Sei combines Ethereum tooling with sub-second finality, enabling developers to build faster and scale further. Sei supports both Solidity and CosmWasm contracts, making it the most composable general-purpose blockchain in production.

__Sei Foundation__
The Sei Foundation and Sei Labs maintain core infrastructure, fund ecosystem growth via the Sei Ecosystem Fund, and support on-chain governance through SEI staking. Developers and validators together shape the protocol’s roadmap—including the upcoming Sei Giga upgrade.
