Oracle

The Role of Oracles

Oracles provide off-chain data to on-chain applications, enabling smart contracts to access real-world market prices securely and trustlessly. In Bullet, oracles are critical for ensuring accurate mark prices, particularly for our perpetual futures exchange.

How Bullet Uses Oracles

• Set Mark Prices – Ensuring liquidations, funding payments, and Profit and Loss (PnL) calculations use an accurate global price.

• Enable Diverse Listings – BulletX can list any perp market that has a reliable on-chain price feed, even if a spot market does not exist.

• Protect Against Manipulation – Using real-time oracle updates and aggregating from multiple publishers reduces the risk of stale or manipulated price data.

High Frequency Oracle

Bullet is excited to be a launch partner for Pyth Lazer, a groundbreaking real-time market data oracle, delivering:

• Millisecond Latency – Prices update in near real-time, far beyond traditional block-based oracles, which is essential for networks like Bullet that process trades every few milliseconds.

• Direct Exchange Feeds – Data sourced directly from major exchanges for high-fidelity pricing.

• Optimized for High-Frequency DeFi – Ensuring smooth operation for Bullet’s perp traders, market makers, and automated strategies.

By leveraging Pyth, Bullet achieves low-latency, highly accurate price updates, creating a CEX-like trading experience on a trust-minimized rollup.
