Company profile
researched Aug 2026Sei (seinetwork.io) is a Layer 1 blockchain positioned as infrastructure for onchain financial markets. Its site describes the network as purpose-built for trading, stablecoins and payments, decentralized finance, tokenized assets, and AI/agentic applications, with onchain order books as a core use case. The chain is EVM-compatible and markets itself as the most performant EVM Layer 1.
The company publishes performance targets tied to its Sei Giga architecture: sub-400 millisecond settlement finality, 200,000 transactions per second execution, and the Autobahn low-latency consensus engine. Sei's own research post (11 April 2025) describes Autobahn as a multi-proposer consensus mechanism delivering a claimed 50x throughput improvement over Tendermint while retaining Byzantine Fault Tolerance. Sei Giga is presented as capable of concurrently supporting payment, trading and consumer AI workloads at scale (illustrated as 3,000 trades/s, 30,000 prompts/s, 65,000 txns/s and 200,000 txns/s).
The website surfaces network metrics β market cap (FDV), monthly transactions, monthly active users, cumulative users, cumulative transactions and stablecoin supply on Sei β though specific values were not captured in the retrieved page. A separate Sei Development Foundation supports builders through grants and funding.
Business model
Sei operates as public blockchain infrastructure rather than a conventional product vendor. Adoption is driven by third-party applications deploying on the network; a related Sei Development Foundation provides grants and funding to builders. The sources do not describe a revenue model.
Traction
The company's website displays live counters for cumulative and monthly users, cumulative and monthly transactions, market cap (FDV) and stablecoin supply on Sei, but the retrieved page did not contain the numeric values. Ecosystem traction cited includes Toku's Sei-native stablecoin payroll launch.
Latest developments
In April 2025 the Sei Foundation announced the funding of the US-based Sei Development Foundation, a non-profit focused on growth and awareness of the Sei protocol. In April 2025 Sei published research on the Autobahn consensus mechanism used by Sei Giga, followed in December 2025 by research on the evolution of consensus toward instant finality. In February 2026 Toku launched Sei-native stablecoin payroll, enabling employee payments and remittances to settle on Sei. In March 2025, media reported that the Sei Foundation was exploring a bid for bankrupt genetic-testing firm 23andMe to move consumer DNA data onchain.

Market position
Sei markets itself as the fastest and most performant EVM Layer 1 blockchain and as an onchain standard for global finance. The available sources contain no independent competitive benchmarking.
Technology
EVM-compatible Layer 1 blockchain. The Sei Giga architecture targets 200K TPS execution and sub-400ms finality, using the Autobahn consensus engine β a multi-proposer, low-latency, Byzantine Fault Tolerant design that the company says achieves roughly 50x the throughput of Tendermint. Sei describes its EVM tooling as battle-tested and integrated with leading developer tooling platforms.
Go-to-market
Developer-led: documentation, builder support, integrations with developer tooling platforms, and grants/funding via the US-based Sei Development Foundation, alongside ecosystem partnerships such as Toku's Sei-native stablecoin payroll.
Developers building EVM applications, and financial market participants: trading venues, stablecoin and payments providers, DeFi protocols, tokenized-asset issuers, and AI/agentic platforms. The site states Sei is used by global firms, funds and infrastructure providers.
Geography
The website presents ecosystem activity across North America, Europe, Africa/Middle East, APAC and Latin America. The Sei Development Foundation, announced in April 2025, is a US-based non-profit.
Risks & controversies
Media coverage from March 2025 reported that the Sei Foundation was exploring acquiring bankrupt genetic-testing company 23andMe in order to place its consumer genetic data onchain, an initiative that raises data-privacy questions. Performance figures such as 200K TPS and sub-400ms finality are company-stated and unverified in the sources provided.
