Price Feeds & Indexing

Scall.io integrates Chainlink Price Feeds as the official source of index prices used for opening, closing, and liquidating option contracts.

đź”— Why Chainlink?

Chainlink is the industry standard oracle network trusted by major DeFi protocols. It provides secure, decentralized, and tamper-proof price data directly on-chain.

🧠 How It's Used

  • When a trader opens a contract, the protocol fetches the current index price from Chainlink to determine the strike.

  • During contract execution or liquidation, the most recent Chainlink price is used to determine whether the contract is In the Money (ITM) or Out of the Money (OTM).

âś… Benefits

1. Decentralization

No single entity controls the price feed. Chainlink aggregates data from multiple premium sources to ensure fair and censorship-resistant pricing.

2. Accuracy

Price data is updated frequently and reflects the real-time market price of the underlying asset (e.g., BTC/USDC), reducing slippage or manipulation risks.

3. Security

Chainlink’s network includes reputation systems, monitoring, and economic incentives to ensure high uptime and resistance to oracle attacks.

4. Transparency

All Chainlink price updates are public and verifiable on-chain, ensuring trust and auditability for traders, LPs, and governance.

5. Automation

By relying on Chainlink feeds, the protocol can autonomously trigger contract conditions (e.g., liquidation, execution) based on objective market data, without needing off-chain computation or human input.

⚖️ With Chainlink, Scall.io ensures that all users interact under a fair, transparent, and decentralized price environment—one of the core pillars of the protocol.
