ChainlinkOracle

The ChainlinkOracle is an oracle that uses Chainlink-compliant feeds to provide price data.

This oracle handles the following cases among others (let's say that our pair is A/B):

• A/B is a feed (typically, stETH/ETH).
• B/A is a feed (typically, ETH/USDC).
• A/C and B/C are feeds (typically, stETH/ETH and USDC/ETH).
• A/C, C/D and B/D are feeds (typically, WBTC/BTC, BTC/USD, USDC/USD).
• A/D, and B/C, C/D are feeds (typically, USDC/USD, WBTC/BTC, BTC/USD).
• A/C, C/D and B/E, E/D are feeds.
• A/C and C/B are feeds (typically, WBTC/BTC and BTC/ETH).
• A'/C and B/C are feeds, and there is an exchange rate between A and A'. (typically A=sDAI and A'=DAI).
