_stEthToEthChainlink

address

The chainlink price feed for stETH/ETH.

_wstETH

address

The wstETH contract address.

_maxTimeFromLastUpdate

Gets the price of wstETH in terms of ETH.

If the beaconchain reserve decreases, the wstETH to stEth conversion will be directly impacted, but the stEth to Eth conversion will simply be determined by the chainlink price oracle.

function getRate() public view returns (uint256 ethPerWstEth);

Returns

NameTypeDescription

ethPerWstEth

uint256

price of wstETH in ETH. [WAD]
