# WstETHOracle

## WstETHOracle

Depending on the equivalence flag price is either based on assumption that 1 stETH = 1 ETH or the price of stETH/USD (secondary market price) is obtained from the oracle.

## Solidity API

#### ASSUME\_STETH\_ETH\_EQUIVALENCE

A flag assuming 1:1 price equivalence between stETH/ETH

```solidity
bool ASSUME_STETH_ETH_EQUIVALENCE
```

***

#### STETH

Address of stETH

```solidity
contract IStETH STETH
```

***

#### WSTETH\_ADDRESS

Address of wstETH

```solidity
address WSTETH_ADDRESS
```

***

#### WETH\_ADDRESS

Address of WETH

```solidity
address WETH_ADDRESS
```

***

#### RESILIENT\_ORACLE

Address of Resilient Oracle

```solidity
contract OracleInterface RESILIENT_ORACLE
```

***

#### constructor

Constructor for the implementation contract.

```solidity
constructor(address wstETHAddress, address wETHAddress, address stETHAddress, address resilientOracleAddress, bool assumeEquivalence) public
```

***

#### getPrice

Gets the USD price of wstETH asset

```solidity
function getPrice(address asset) public view returns (uint256)
```

**Parameters**

| Name  | Type    | Description       |
