Inherits:FluidOracleL2, FallbackOracleImpl2, UniV3CheckCLRSOracleL2

Gets the exchange rate between the underlying asset and the peg asset by using:

  1. rate from Chainlink price feeds (or Redstone as fallback).
  2. result from 1. combined with a uniV3CheckCLRSOracle to get from someToken <> someToken2 e.g. when going from wstETH to USDC:
  3. wstETH -> stETH -> ETH Chainlink feed.
  4. ETH -> USDC via UniV3 ETH <> USDC pool checked against ETH -> USDC Chainlink feed.
