WstETHCLRSOracle

Gets the exchange rate between the underlying asset and the peg asset by using: wstETH Oracle price in combination with rate from Chainlink price feeds (or Redstone as fallback), hopping the 2 rates into 1 rate. e.g. when going from wstETH to USDT: wstETH -> stETH wstETH Oracle, stETH -> ETH Chainlink feed, ETH -> USDT Chainlink feed.

constructor

constructor(contract IWstETH wstETH_, uint8 mainSource_, struct ChainlinkStructs.ChainlinkConstructorParams chainlinkParams_, struct RedstoneStructs.RedstoneOracleData redstoneOracle_) public

sets the wstETH address, main source, Chainlink Oracle and Redstone Oracle data.
