## About Sei Network

[**Sei**](https://www.sei.io/) is an ultra-fast Layer 1 blockchain designed for low-cost, high-speed financial transactions. It combines Ethereum’s security and developer familiarity with Solana-like performance, and since launching in 2023 has processed billions of transactions across more than 60 million wallets.

Sei now operates as an EVM-only blockchain following the SIP-3 update, streamlining its architecture for simplicity, better developer experience, and stronger positioning within the broader EVM ecosystem, all while maintaining its performance edge.
