The Coinbase Oracle is a verifiable price feed for the BTC/USD and ETH/USD markets that anyone can publish on-chain. The price feed is accessible through a centralized API, and is updated every minute with data sourced from Coinbase Pro.

All posted prices are signed using the Oracle’s public key. This allows anyone to post price data on-chain, without trusting the poster of the data. The Oracle implements a filtering mechanism that automatically rejects price points that significantly deviate from the reported asset’s expected volatility. The result is a trusted, but reliable feed that any DeFi protocol can integrate easily.
