SEI is the native token of the Sei Network, a Layer 1 blockchain purpose-built for trading and order-book decentralised finance. Sei's twin-turbo consensus mechanism and native parallelisation are designed to achieve sub-400ms finality — significantly faster than most competing L1s. The Sei v2 upgrade introduced full EVM compatibility, allowing Ethereum developers to deploy without rewriting contracts. A native order-book primitive is built directly into the base layer, removing the need for off-chain matching. People buy SEI to pay transaction fees, stake for validator rewards at approximately 6–10% APY, and access trading-focused DeFi applications such as DragonSwap.

BitMEX was founded in 2014 and has maintained an 11-year security record with no customer cryptocurrency ever lost to a security intrusion. Security measures include multi-signature cold storage, mandatory KYC/AML, two-factor authentication, and withdrawal address whitelisting. Over 2.1 million traders have used the platform. Purchases are processed through regulated payment partners Banxa and Mercuryo, adding an additional compliance and consumer-protection layer.

After buying SEI on BitMEX, you can stake SEI to validators on the Sei Network for approximately 6–10% APY using Compass Wallet (Sei's native wallet) or MetaMask via the Sei EVM.
