Sei (SEI) is the native token of the Sei Network, a high-performance layer-1 blockchain optimized for trading and exchange applications. Built using the Cosmos SDK, Sei is designed to offer low-latency execution, instant finality, and deep liquidity — making it ideal for decentralized exchanges (DEXs), perpetuals, NFTs, and high-frequency trading platforms.
Sei introduces a twin-turbo consensus mechanism, which combines parallel transaction processing with intelligent block propagation to significantly reduce time-to-finality. It also features native order matching at the chain level, allowing protocols to offer a central-limit order book experience while remaining fully decentralized.
The SEI token powers the network by serving as the primary asset for transaction fees, staking, and governance. Token holders can delegate their SEI to validators, help secure the chain through proof-of-stake, and vote on key upgrades, ecosystem grants, and protocol parameters.
SEI is currently priced at $0.05, with a market capitalization of $357,472,575.10. The token reached its all-time high of $1.14 on . There are 7,699,722,222 SEI tokens in circulation, from a total supply of .
