The current SEI price is $0.32 as in the last 24 hours its value has changed by -1.12%. SEI ranks number 70 in terms of market capitalization. SEI is a decentralized currency, which means you can buy, sell, and exchange it without having to rely on traditional monetary systems.

What is Sei (SEI)?

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 $0.32, with a market capitalization of $1,873,726,188.00. The token reached its all-time high of $1.14 on March 16, 2024. There are 5,781,805,555 SEI tokens in circulation, from a total supply of 10,000,000,000.

With an application-specific architecture, Sei is designed to support high-performance trading and financial applications. Its structure addresses scalability and latency limitations found in general-purpose blockchains.
