Institutional Fair Value
for Crypto Perpetual Markets
Traditional equity markets close at 4pm. Crypto synthetic equity perps trade 24/7. Get institutional-grade fair value when Bloomberg terminals go dark.
The 24/7 Fair Value Gap
Crypto synthetic equity perpetuals trade around the clock across Hyperliquid, Avantis, and Ostium. But institutional fundamentals only exist during market hours.
Traditional markets have institutional infrastructure.
Crypto perps have been guessing. Until now.

Four Layers of Intelligence
Institutional Equity Models Applied to Crypto Perps
We model the underlying equities using institutional-grade infrastructure, then project fair value onto 24/7 perp markets.
At 3am Saturday, SPY-PERP trades at $586. Our fair value stays at $585.20, anchored to fundamentals. You get a reference point when no one else has one.
Cross-Venue Arbitrage Opportunities
Crypto perp venues don't share liquidity. This creates persistent mispricings we quantify in real-time.
Hyperliquid: $585.10 (15bp cheap) / Avantis: $585.60 (35bp rich) / Fair value: $585.25 — 50bp spread opportunity.
Know When NOT to Trade
Not all market conditions are tradeable. We classify real-time regime and risk indicators.
Event-risk flags: 'Elevated event risk — consider reducing exposure before announcement.' Protecting capital is alpha.
