Data rules

• Numbers are snapshots refreshed about every 2 hours, not a live feed. Quote the as_of time.
• HYPE price is the canonical HYPE perp mark. Delisted HIP-3 markets are flagged and left out of totals.
• Funding is annualized as hourly × 24 × 365 (simple). Positive means longs pay shorts.
• Referral codes are UnderHyper's own; we earn a share of fees from accounts that use them (disclosure). That never changes the data.
• Hyperliquid's terms restrict the United States, Ontario and other places. Nothing returned is financial advice.
