constructor

Creates a new weEthwstEthReserveOracle instance. Provides the amount of wstETH equal to one weETH. wstETH / weETH = eETH / weETH * ETH / eETH * wstETH / ETH. ETH / eETH is 1 since eETH is rebasing. Depeg here would reflect in eETH / wETH exchange rate.

The value of weETH denominated in wstETH by the provider.

constructor(
    uint8 _ilkIndex,
    address[] memory _feeds,
    uint8 _quorum,
    uint256 _maxChange
)

Parameters

Name	Type	Description
