SeiSEI

Sei is a layer-1 blockchain that was designed for fast trading and financial applications, and SEI is its native token. It was built by Sei Labs, which was co-founded by Jeff Feng and Jay Jog, and the Sei Foundation supports the ecosystem. The mainnet launched on August 15, 2023, and the SEI token began trading on the same day.

Sei started as a network that was built with the Cosmos SDK and that had features for trading, such as a built-in order matching system. In 2024, the Sei v2 upgrade added a parallelized version of the Ethereum Virtual Machine (EVM), which processes many transactions at the same time when they do not conflict, so that developers can use Ethereum tools on the network. In 2025, the community approved SIP-3, a governance proposal to move Sei toward an EVM-only design. The network is secured by validators and delegators through delegated proof-of-stake, and SEI is used to pay fees, to stake and to vote on governance proposals.

SEI has a maximum supply of 10 billion tokens. A large part of the supply is reserved for the ecosystem and staking rewards, and allocations for the team and investors are released over time through vesting. Current circulating and total supply figures are shown at the top of this page.

SEI began trading in August 2023. The all-time high and the full price history are shown on this page.
