Entropy Guides & Tutorials

Everything you need to trade Entropy well, from your first deposit to reading the fine print on how io:ANTH settles. Start at the EntropyGuides homepage for a quick overview.

About Entropy & How to Use These Guides

Entropy is a perpetuals venue built on top of Hyperliquid, operated by Bursa Global Inc. under Hyperliquid's HIP-3 framework. Traders sign in with email or a Web3 wallet, bridge USDC from Arbitrum One, and place a trade with no identity verification. Entropy deploys exactly two markets of its own, io:ANTH (an Anthropic pre-IPO perpetual) and io:SNDK (a SanDisk equity perpetual), and its frontend also aggregates 317 markets deployed by other HIP-3 operators, chiefly trade.xyz. Trading went live on August 19, 2026, which makes Entropy a genuinely new venue: treat every number on this site, and on Entropy's own dashboards, as something that moves daily.

This hub organizes every Entropy guide into three categories, plus the standalone comparison, ecosystem, privacy and troubleshooting hubs linked below. New users should start with Getting Started, which walks through wallet connection, USDC deposits, and the two approvals required before a first trade. Trading covers how io:ANTH and io:SNDK are priced, margined, and settled, including the implied-valuation mechanic that makes io:ANTH different from a normal perp. Fees & Savings explains the published rate against the real Growth Mode rate, and what the referral rebate is actually worth once the fee split is accounted for.

Beyond the three guide categories, Comparisons sets Entropy against trade.xyz and the other venues where an Anthropic pre-IPO contract trades, Ecosystem covers HIP-3 mechanics, the deployer landscape and the token question, Privacy & Security covers the risk model and which jurisdictions Entropy's terms exclude, and Troubleshooting addresses common deposit and order issues.

Every guide cites its source, whether that is Entropy's own documentation, the Hyperliquid API, or a figure we measured ourselves. Where a number is not sourced, we say so rather than publish a guess. Browse the category cards below to jump directly to a topic, or scroll through the full article listing to find what you need.
