How Aster computes funding
- Interval
- Per market: 1, 2, 4 or 8 hours (at the time of writing 98 markets on 1h, 362 on 4h, 323 on 8h)
- Interest component
- 0.01% per 8 hours (0% for BNBUSDT)
- Premium and clamp
- clamp(interest − premium, −0.05%, +0.05%); premium index calculated every 5 s; funding fee cap/floor ±2% per market
- Formula
F = [average premium index + clamp(interest − premium, −0.05%, +0.05%)] / (8 / N), where N is the funding interval in hours
Funding is peer-to-peer on all three venues: the exchange does not take a cut of funding payments. Source: Aster docs: Funding Rate.
