Oracles

PrimeFi relies on Chainlink as its decentralized oracle network of choice, providing highly secure, reliable, and tamper-resistant data.

The vast majority of price pairs in PrimeFi are powered by Chainlink DataStreams, ensuring low-latency updates, continuous reliability, and robust performance across both Base and Arbitrum instances. In specific cases, DataFeeds are used, and for PRFI-USD, a dedicated DataLink is integrated.

Why Chainlink?

• DataStreams (used in most cases) deliver continuous, low-latency market data, which is critical for maintaining protocol integrity.

• DataFeeds provide additional reliability where historical precision or broader compatibility is required.

• DataLink is specifically used for PRFI-USD, reflecting the token’s unique role within the Prime Numbers Labs ecosystem.

By combining these Chainlink services, PrimeFi minimizes risks of stale or manipulated price data, ensuring healthy loan positions, cross-collateralization, liquidations, and other core protocol functions.
