#### **`unwrap`**

If wrapped amount is greater than 0, remove wrapped amount from curve's liquidity and deposit balance of the contract to the wrapped ethereum.

```
function unwrap(uint256 wrapped_amount) internal override returns (uint256 result_val)
```

#### **`wrap`**

Calculates wrapped amount from want amount, removes wrapped tokens from wrapped ethereum and after converting them, deposits them to the curve's pool.

```
function wrap(uint256 want_amount) internal override returns (uint256 expected_return)
```
