Multi-Source Price Aggregation

Multi-source price aggregation is the process of collecting and synthesizing trade data from multiple independent exchanges and liquidity providers to establish a single, accurate reference price for an asset. In cryptocurrency and derivatives markets, prices can vary significantly between venues due to fragmented liquidity and different market microstructures.

By gathering feeds from various sources, aggregators filter out outliers, account for volume weighting, and mitigate the risk of price manipulation on any single exchange. This unified price, often referred to as an index price, is critical for the accurate valuation of derivatives, margin requirements, and liquidation triggers.

It ensures that traders are not unfairly liquidated due to temporary, localized price anomalies. This mechanism serves as a foundational layer for decentralized finance protocols that rely on reliable external data.

Without robust aggregation, smart contracts would be vulnerable to oracle manipulation, where an attacker artificially moves the price on one exchange to trigger liquidations. Ultimately, this process provides a more stable and representative view of market value across the entire ecosystem.
