Oracles
PrimeFi leverages decentralized oracle networks to ensure that price data is secure, reliable, and tamper-resistant. In most chains, DataStreams deliver continuous updates with low latency, while DataFeeds provide historical precision and compatibility. For key ecosystem tokens (e.g. PRFI, HYPE), we employ DataLink, which offers a dedicated oracle channel.
On XDC, all price data is sourced via eOracles / ePRICE feeds, which integrate with the AggregatorV3Interface. EO Docs

3. XDC Network
All oracles on XDC use eOracles / ePRICE feeds.
XDC
eOracle / ePRICE Feed

Technical Rationale
DataStreams → Ideal for low-latency continuous updates (real-time trading).
DataFeeds → Offer dependable historical data and broad compatibility.
DataLink → Reserved for strategic tokens needing dedicated oracle infrastructure.
eOracles / ePRICE feeds (XDC only) → Provide on-chain price feeds in the XDC ecosystem, integrated via AggregatorV3Interface. EO Docs
By combining these methods appropriately per network and asset, PrimeFi ensures the optimal balance of performance, reliability, and accuracy.
