WstETHCLRS2UniV3CheckCLRSOracle ​

Git Source

Inherits:FluidOracle, WstETHOracleImpl, FallbackOracleImpl2, UniV3CheckCLRSOracle

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

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

Functions ​

constructor ​
