Oracle

Stork Oracle

RISEx uses Stork for price feeds. Stork is a high-frequency oracle network designed for DeFi applications requiring realtime pricing.

Update Frequency

Prices are updated onchain every 500ms — twice per RISE block (RISE blocks are ~1 second).

This frequency ensures:

• Accurate mark prices for margin calculations
• Fair liquidation triggers
• Reliable funding rate computations

How It Works

Stork aggregates prices from multiple sources and publishes them onchain with cryptographic attestations. The oracle network is designed for low-latency delivery, matching the performance requirements of realtime trading.

Staleness

If a Stork feed goes stale (no update for 1 hour), the market's oracle price is treated as stale and:

• New orders on that market are blocked
• Liquidations on that market are blocked

Existing positions and open orders are unaffected until the feed resumes updating.

Onchain Verification

Index and mark prices can be read directly from RISExOracle:

interface IRISExOracle {
    function getIndexPrice(uint16 marketId) external view returns (uint256);
    function getMarkPrice(uint16 marketId) external view returns (uint256);
}
