Funding is the mechanism that keeps Astaria perpetuals aligned with their underlying event-market reference price. When the perpetual trades above the Index Price, longs may pay shorts. When it trades below the Index Price, shorts may pay longs.

​
Premium Signal

Astaria measures the difference between:
  • The perpetual Mark Price
  • The event-market Index Price
This difference is the funding premium.

​
Boundary-Aware Funding

Event markets behave differently near the boundaries of 0 and 1. A small absolute deviation near 0.02 or 0.98 can represent a large relative distortion. For that reason, Astaria’s funding model may apply additional correction in boundary regions. This makes funding more responsive when:
  • The market is close to resolution
  • The probability is near 0 or 1
  • Relative deviations become economically larger than the raw basis suggests

​
Funding Payments

Funding transfers occur between long and short traders and do not represent a protocol fee. The exact funding schedule and calculation parameters may vary by market and will be published in the relevant market specification.
