Sei Network Layer 1

Sei is a Layer 1 blockchain positioned as infrastructure for trading and digital asset markets. Its architecture is EVM-compatible and is presented around five application areas: trading, stablecoins and payments, decentralized finance, tokenized assets, and AI and agentic economies. The network advertises sub-400ms settlement finality, execution throughput of up to 200,000 transactions per second, and the Autobahn consensus engine designed for low latency. A forthcoming iteration, Sei Giga, is described as able to support payment, trading and consumer AI workloads simultaneously, with illustrative capacities of 3,000 trades per second, 30,000 prompts per second and 65,000 to 200,000 transactions per second.

Earlier technical descriptions of Sei centered on parallel transaction processing, a twin-turbo consensus mechanism combining intelligent block propagation with optimistic block processing, and a native order matching engine embedded in the chain's dex module. Parallelization is applied both to transaction execution, via dependency mappings that allow messages touching different state keys to run concurrently, and to end-of-block order matching, where orders in independent markets are processed in parallel. The native matching engine exposes a flexible interface so that decentralized exchanges building on Sei can define how assets are represented.

The ecosystem is supported by the Sei Development Foundation, a US non-profit funded by the Sei Foundation in April 2025 to advance protocol adoption and provide grants and funding to builders. As of April 2026, on-chain reporting described a network with roughly 1 to 1.2 million daily active users, about $41.6 million in total value locked (down from a July 2025 peak near $626 million), approximately $251 million in bridged liquidity and around $179 million of stablecoin market capitalization.

Business model

Sei operates a public Layer 1 blockchain whose native SEI token underpins network activity; application-level fees and protocol revenue on the network were reported at modest levels ($11,155 in app fees and $2,872 in revenue over a 24-hour window in April 2026). Ecosystem growth is funded through an ecosystem fund and through grants administered by the Sei Development Foundation rather than through direct product sales.

Traction

As of April 2026, reported network metrics included 1 to 1.2 million daily active users (down from over 2 million earlier that month), roughly $41.6 million in total value locked versus a peak near $626 million in July 2025, 24-hour DEX volume of $6.55 million and perpetuals volume of $12.25 million, bridged liquidity of about $251 million and stablecoin market capitalization near $179 million. The SEI token had a market capitalization of approximately $369 million and a fully diluted valuation of about $549 million. Ahead of mainnet, more than $120 million was reported to sit in the Sei ecosystem fund.

Latest developments

In December 2025 Sei published research on the evolution of consensus toward instant finality, and in February 2026 Toku launched stablecoin payroll settled natively on Sei for employee payments and remittances. Earlier, in March 2025, the Sei Foundation was reported to be exploring a bid for bankrupt genetic-testing company 23andMe to place consumer DNA data onchain, and in April 2025 it funded the US-based Sei Development Foundation. April 2026 on-chain data showed declining total value locked and slowing new-user growth alongside stable returning-user activity.
