Funding basis

Binance settles funding every 8 hours and Hyperliquid accrues hourly. Every rate below is normalised to bps per 8 hours before it is differenced; ΔFR is what $FR-BASIS settles against.

The native leg is modelled. Robinhood Chain has no public perp funding feed yet, so that leg is set to the reference mean plus a fixed premium. The references cancel out of the difference, which makes the ΔFR shown here a model output rather than a market. Binance and Hyperliquid are live reads.

Settlement

cash flow = size × ΔFR × Δt ÷ 28,800
ΔFR > 0
Native funding is rich. Longs pay shorts.
ΔFR < 0
Native funding is cheap. Shorts pay longs.
Δt
Seconds since the position was last touched.
28,800
Seconds in the 8-hour reference interval.

Accrual is per second, so four minutes of exposure pays four minutes of carry. This is the specification: no deployed contract accrues it yet. FR-BASIS engine
