    About Sei

    Sei is a layer-1 blockchain optimized specifically for trading applications, featuring built-in orderbook infrastructure and sub-second finality. The network employs a sector-specific approach, focusing on exchange and trading use cases rather than general-purpose applications. Sei utilizes a proof-of-stake consensus mechanism and includes native features like frequent batch auctioning to prevent frontrunning. The protocol targets decentralized exchanges and trading platforms requiring high throughput and low latency.

    Primary use case: Purpose-built layer-1 blockchain optimized for decentralized exchange and trading applications.

    Understanding Sei Price Data

    The Sei price shown above is a volume-weighted average across major spot exchanges, sourced from CoinGecko and refreshed continuously throughout the trading day. Cryptocurrency markets trade twenty-four hours a day, seven days a week — there is no opening or closing bell — so the 24-hour change figure is a rolling window measured against the price exactly one day prior, not against a fixed daily close. The 7-day and 30-day percentage moves use the same rolling-window methodology, which means the figures shift continuously rather than resetting at midnight.

    Market capitalisation for Sei is calculated by multiplying the current price by the circulating supply — the number of SEI units currently in public hands and not locked, burned, or reserved by the protocol. This differs from total supply (all units that have ever been created) and max supply (the protocol-defined cap, where one exists). For assets with significant locked or vesting allocations, fully diluted valuation can be a more useful long-term measure than market cap alone. The 24-hour trading volume figure aggregates spot trading across reporting exchanges and excludes derivatives and over-the-counter activity, which can be substantially larger for major assets.

    All-time high (ATH) figures reflect the peak USD price ever recorded for Sei on a major exchange. The ATH change percentage shows how far the current price sits below — or above — that peak, and is one of several inputs the CoinHours Market Cycle Indicator uses when assessing where the broader market sits in its four-year halving cycle. For longer-term investors, ATH drawdown combined with 200-week moving average position and the Fear & Greed Index gives a clearer cycle picture than any single metric in isolation.

    Sei for Australian Investors

    In Australia, the Australian Taxation Office (ATO) treats Sei and other cryptocurrencies as capital gains tax (CGT) assets rather than as currency. Every disposal — selling for AUD, swapping for another crypto, spending on goods or services, or gifting — is a CGT event that must be reported in your tax return. Holding SEI for more than twelve months before disposing of it qualifies you for the 50% individual CGT discount, which is one of the most significant tax planning levers for long-term holders. See the crypto tax encyclopedia entry for a full breakdown of ATO record-keeping requirements, cost-base calculation methods, and the tax treatment of staking rewards, airdrops, and DeFi income.

    Australian investors typically buy Sei through a registered exchange that complies with AUSTRAC anti-money-laundering requirements. Once acquired, holdings can be left on the exchange (counterparty risk), moved to a software wallet (convenience with online attack surface), or transferred to a hardware wallet for cold-storage self-custody (highest security, least convenient). The CoinHours security guide walks through the trade-offs in detail, including seed-phrase storage, multi-signature setups, and inheritance planning. For background on the underlying technology, the Crypto Encyclopedia covers blockchain fundamentals, consensus mechanisms, and the Sei protocol in plain English.

    Sei FAQ

    What makes Sei different from other blockchains?

    Sei is purpose-built specifically for trading applications, featuring native orderbook infrastructure and sub-second finality. Unlike general-purpose blockchains, Sei optimises exclusively for decentralised exchanges and trading platforms, including built-in features like frequent batch auctioning to prevent frontrunning.

    How does Sei prevent frontrunning in trading?

    Sei implements frequent batch auctioning as a native feature to combat frontrunning. This system groups transactions together and processes them in batches rather than sequential order, preventing larger traders from exploiting transaction ordering to gain unfair advantages over other market participants.

    What are the tax implications of trading SEI in Australia?

    SEI is treated as a cryptocurrency by the Australian Taxation Office (ATO), meaning trading may trigger capital gains tax obligations. Australian investors must maintain detailed records of all SEI transactions, including purchase prices, sale prices, and dates, for tax reporting purposes.

    Can any type of application build on Sei?

    Sei is specifically designed for trading and exchange applications rather than general-purpose use cases. The blockchain optimises for spot exchanges, derivatives platforms, automated market makers, and similar trading-focused applications that can benefit from its specialised orderbook infrastructure.

    What consensus mechanism does Sei use?

    Sei operates on a proof-of-stake consensus mechanism, similar to many modern blockchains. However, it incorporates trading-specific optimisations including sub-second finality to enable faster trade confirmation and settlement compared to general-purpose blockchain networks.

    What are the main risks of investing in SEI?

    Key risks include Sei's narrow focus limiting its user base compared to general-purpose blockchains, competition from established networks improving their trading features, regulatory changes affecting decentralised exchanges, and the inherent volatility of cryptocurrency markets affecting infrastructure tokens.

    Frequently Asked Questions

    How often is the Sei price updated?

    CoinHours pulls live SEI pricing from CoinGecko, which aggregates trades across major exchanges. The page refreshes the displayed figures every few minutes; the underlying market data updates continuously and may move significantly between refreshes during volatile sessions.

    Why does the Sei price differ between exchanges?

    Each exchange runs its own order book, so prices drift slightly based on local supply and demand, regional liquidity, and pair availability. The figure shown here is a weighted average designed to represent the broad market price rather than any single venue. Arbitrage typically keeps the differences small for major assets but can widen during fast moves or on smaller exchanges.

    Is buying Sei legal in Australia?

    Yes. Cryptocurrency is legal to buy, hold, and trade in Australia. Exchanges operating in Australia must register with AUSTRAC and comply with anti-money-laundering and counter-terrorism financing rules. The ATO treats crypto as property for tax purposes — see the Australian investors section above for tax implications.

    What is market cap and why does it matter?

    Market capitalisation equals current price multiplied by circulating supply and gives a rough measure of an asset's total value in public hands. It is a more meaningful comparison metric than price alone because two coins with identical prices can have radically different supplies. Market cap rank is one input investors use when assessing relative size, but it does not account for locked tokens, future emissions, or actual on-chain liquidity.

    Should I store Sei on an exchange or in a wallet?

    Exchange custody is convenient but exposes you to counterparty risk — exchange failures and hacks have wiped out customer balances historically. For amounts material to your finances, a hardware wallet under your own control is the standard recommendation. Read the security guide for a full comparison of custody options and seed-phrase best practices.
