Plain English
Sei is a Cosmos-SDK L1 launched in 2023, purpose-built for trading. SEI is the native token. The chain features built-in matching-engine logic at the protocol level — meaning order books and DEX functionality work without separate smart-contract overhead.
How it actually works
Sei V2 introduced parallel execution and EVM compatibility, letting Ethereum contracts deploy alongside native Cosmos smart contracts. Order-matching and price-update operations are accelerated by chain-level functions. Strong focus on perpetual DEXes, NFT marketplaces, and high-frequency consumer apps.
What it means for you
SEI is a vertical-play L1 — built for trading, attractive for DEX-native applications. For HNW positioning, SEI is a higher-volatility bet on the chain capturing trading infrastructure share. Stake for ~5–6% native yield.
