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

Comparative Overview by Network & Assets

1. Base Network

Asset	Oracle Type	Notes
cbBTC	DataStream / DataFeed	Flexible usage depending on latency or historical requirements
USDC	DataStream / DataFeed	Continuous feed or fallback feed as needed
ETH	DataStream / DataFeed	Redundancy through feed fallback
PRFI	DataLink	Dedicated channel for PRFI-USD
psXDC	DataStream (XDC/USD)	Priced at the XDC/USD Data Stream (1 psXDC ≈ 1 XDC)

2. HyperEVM

Asset	Oracle Type	Notes
HYPE	DataLink	Specialized oracle for HYPE-USD
UETH	DataStream / DataFeed	Similar logic to ETH
PRFI	DataLink	Consistent with Base network usage
USDT0	DataStream / DataFeed	Stream first, feed as fallback
UBTC	DataStream / DataFeed	Equivalent to cbBTC in HyperEVM
psXDC	DataStream (XDC/USD)	Priced at the XDC/USD Data Stream (1 psXDC ≈ 1 XDC)

3. XDC Network

All oracles on XDC use eOracles / ePRICE feeds.

Asset	Oracle Type	Notes
XDC	eOracle / ePRICE Feed	Price via eOracles
psXDC	eOracle / ePRICE Feed	Synthetic / pegged derivative on XDC
USDC	eOracle / ePRICE Feed	Stablecoin feed via eOracle
USDT0	eOracle / ePRICE Feed	ePRICE feed for USDT0
PRFI	eOracle / ePRICE Feed	Treated as standard asset feed in XDC

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.
