What is SEI (Sei Network)?

Sei (SEI) is the native token of the Sei Network — a high-performance Layer-1 blockchain purpose-built for fast, low-cost financial applications including decentralised exchanges, trading platforms, NFT marketplaces, and gaming. Founded by Jay Jog and Jeff Feng with backing from Multicoin Capital, Jump Crypto, Coinbase Ventures, OKX Ventures, and Circle Ventures, Sei launched its mainnet in August 2023 following a $95 million fundraise. Sei combines EVM compatibility with Solana-like performance — making it one of the very few Layer-1 blockchains that appeals to both Ethereum and Solana developer ecosystems simultaneously. Sei has processed over 5 billion transactions across more than 90 million wallets, and in January 2026 partnered with Bhutan's national investment body Druk Holding and Investments to deploy a sovereign validation node. The highly anticipated Sei Giga upgrade, targeting over 200,000 transactions per second with sub-400ms block finality, is the network's most significant catalyst in 2026. SEI is available on major AUSTRAC-compliant platforms including Coinbase, making it accessible to Australian investors. Uptrade is Australia's trusted Sei Network broker — making it simple, secure, and fast for investors across Australia.
