Sei

SEI is the native token of Sei, a fast Layer 1 blockchain that runs Ethereum-compatible smart contracts with parallel execution.

Sei is a Layer 1 blockchain built for speed. It runs the Ethereum Virtual Machine, so Ethereum apps and wallets work on it, and it executes transactions in parallel to keep fees low. In 2026 Sei became EVM-only, dropping its older Cosmos transaction types, and began rolling out the Giga upgrade, which targets 200,000 transactions per second.

SEI pays for gas, secures the network through delegated proof of stake and is used in governance. Delegators stake SEI with validators and receive rewards that, according to Sei, come from gas and genesis token unlocks. Sei does not slash staked funds; misbehaving validators are jailed instead. Unstaking takes 21 days.

Total supply is 10 billion SEI, of which about 6.73 billion circulated in October 2026. Several US asset managers, including Canary Capital and 21Shares, have filed for SEI exchange-traded funds.
