#### unwrapWSEI <a href="#unwrapwsei" id="unwrapwsei"></a>

Unwraps the contract's WSEI balance and sends it to msg.sender as SEI.

```solidity
function unwrapWSEI(uint256 amountMinimum) external payable;
```

| `amountMinimum` | `uint256` | The minimum amount of WSEI to unwrap |

#### wrapSEI <a href="#wrapsei" id="wrapsei"></a>
