How Chainlink oracle price feeds work — architecture, reading feeds on-chain, available pairs, the aggregator model, and oracle security. Covers how DeFi protocols (Aave, Sperax, Compound) rely on Chainlink for accurate pricing. Use when explaining oracles, price feeds, or DeFi infrastructure.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Chainlink Oracle Price Feeds Guide Chainlink is the dominant oracle network in DeFi. This guide explains how it works and how to use price feeds. ## What Problem Do Oracles Solve? Smart contracts can't access external data (prices, weather, events). Oracles bridge this gap: ``` Off-chain world Oracle Network On-chain world ┌──────────────┐ ┌──────────────┐ ┌──────────────┐ │ Binance API │───┐ │ │ │ │ │ Coinbase API │───┤ │ Chainlink │ │ Aave │ │ Kraken API │───┼───►│ Oracle Nodes│───────►│ Compound │ │ DEX Pools │───┤ │ (median) │ │ USDs/Sperax │ │ Other feeds │───┘ │ │ │ Uniswap │ └──────────────┘ └──────────────┘ └──────────────┘ ``` Without reliable oracles, DeFi protocols can't: - Determine collateral value (lending) - Maintain stablecoin pegs - Calculate liquidation thresholds - Execute fair swaps ## How Chainlink Works ### The Aggregator Model 1. **Data sources**: Multiple professional data providers (nodes) fetch prices from CEXes, DEXes, and other sources …

How to install
mdr add nirholas/three.ws/chainlink-oracle-guide@sha256:c41dae9f157362f0The line at the top of this page pins the label git:20260501.87cefc9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
