Oracles, Fees & Fee Settlement

There is a lot to cover when it comes to oracles and fees on Horizon Exchange. We’re going to provide a quick run-down of what they mean, organize a M.E.T.H. event to discuss further, and arrange for in depth articles/documentation to clarify.

Oracles:

Horizon Protocol Synthetic Assets (zAssets) need regular on-chain price feeds. Refreshing the price costs gas, making constant price checks financially unfeasible at this time. To solve this, oracles refresh prices based on two variables:

  • Heartbeat — a predetermined time period (e.g. every 4 hours)
  • Variance — a predetermined price threshold (e.g. 0.2% change in price)

Fees:

Every zAsset has its own oracle price feed and therefore a corresponding heartbeat and price variance threshold. If a zAsset has a price variance threshold of 1%, the exchange fee on Horizon Exchange will also be 1% in order to disincentivize users from using the variance threshold to front-run the oracle’s price.

Fee settlement:

There’s an issue with this system of refreshing a price feed: the lag time between a price being observed from the market and the time it is updated on-chain.
