What is Sei Network?

Sei is a Layer 1 blockchain originally built on the Cosmos SDK and focused on high-performance trading. Sei V2 introduced EVM compatibility, allowing Solidity developers to deploy directly alongside the chain's existing CosmWasm environment — making it one of the few chains that supports both execution environments natively. The consensus layer uses an optimized version of Tendermint targeting sub-second finality, with built-in features like parallelized execution and native order matching designed for trading applications. SEI is the native gas and staking token. The ecosystem has focused heavily on DEXs, perpetuals, and trading-oriented infrastructure. For users bridging to Sei, the EVM side is the most relevant entry point for standard DeFi activity.
