HOW THE CHECK WORKS
How Perp Verdict
calculates funding arbitrage.
Perp Verdict turns a public funding differential into a transparent cost model. Every result is a read-only estimate with its assumptions and freshness state visible.
01 / What is measured
A funding spread can disappear in the cost stack.
The scanner compares public perpetual-market funding data across supported venues, then subtracts modeled costs that a headline rate leaves out. It is designed to expose uncertainty, not to manufacture a trade.
funding differential − fees − depth impact − transfer reserve − liquidation buffer02 / The sequence
Five checks before a verdict appears.
- Normalize the funding interval.Rates are compared only when the venue-reported cadence is comparable.
- Subtract round-trip fees.Both sides of the modeled route receive an explicit fee allowance.
- Estimate visible-book impact.Available public order-book levels are used as a depth constraint, not as proof of a fill.
- Reserve for transfer time.A cross-venue route has time and operational uncertainty, so the model keeps a configurable reserve.
- Hold a liquidation buffer.Leverage and liquidation risk are not reduced to a funding percentage.
03 / Reading the result
Statuses are guardrails, not signals.
Review means the current modeled net survives the configured checks, but it still depends on public snapshots and assumptions.
Reject means modeled costs consume the observed differential or validation fails.
Unavailable on a shareable Truth Card means its server snapshot failed closed because a source, timestamp, cadence, or depth check was not trustworthy.
The interactive homepage may retain clearly labeled conservative seed inputs while a venue stream is unavailable; those seeds are never substituted into a server Truth Card.
04 / Hard boundary
What Perp Verdict does not do.
It does not connect exchange accounts, accept API keys, place orders, move funds, predict prices, or guarantee a return. A public snapshot is not a fill, and a modeled result can change before a human could act.
