Use this page when

If you need…Use this page because…
the public baseline for funding-rate clamps and zero bandit is the factual reference carrier for those bounds
the timing rule for when funding is appliedit states the settlement-boundary timing contract directly
the exact numeric bounds behind funding references elsewhere in the docsit isolates those constants cleanly

Funding computation shape

StagePublic contract
InputFunding uses the average premium rate across the relevant price-checkpoint window
Zero-band clampThe average premium is first passed through the small positive and negative zero-band bounds
Outer clampThe result is then clamped again to the hard upper and lower funding bounds
Settlement directionPositive funding means longs pay and shorts receive; negative funding reverses that direction

Funding timing

ParameterValue
DEFAULT_FUNDING_SETTLEMENT_MULTIPLIER1
Funding applied atsettlement boundaries

Environment note

The default public settlement multiplier is 1, but the runtime carrier can override it through the FUNDING_SETTLEMENT_MULTIPLIER environment path. Treat the default as the public baseline, not as an untouchable constant for every deployment.

Reading notes

TopicPublic reading
zero boundssmall positive and negative average premium ranges that remain inside the zero-band logic
outer boundshard upper and lower clamps for funding-rate results
settlement timingfunding is applied on settlement boundaries rather than per-fill

Boundary rule

This page is the numeric funding reference. Use Price Formation, Risk Controls, and Solvency when you need the broader rationale for how funding fits the perpetual risk model.
