Interface for wrapping and unwrapping the native Flare token (FLR/SGB/C2FLR/CFLR) into the ERC-20 representation WNAT.

Sourced from `IWNat.sol` in [`@flarenetwork/flare-periphery-contracts`](https://www.npmjs.com/package/@flarenetwork/flare-periphery-contracts) (v0.1.41+).

The published `IWNat` interface only declares the four functions below. The ERC-20 surface area (`balanceOf`, `transfer`, `approve`, `allowance`, ...) is inherited via the WNat implementation contract, not the `IWNat` interface; if you need those methods, import [`IVPToken`](https://github.com/flare-foundation/flare-smart-contracts-v2/blob/main/contracts/userInterfaces/IVPToken.sol) (which extends `IERC20`) instead. Vote-power and delegation methods (`delegate`, `governanceVotePower`, ...) come from `IVPToken` + [`IGovernanceVotePower`](https://github.com/flare-foundation/flare-smart-contracts-v2/blob/main/contracts/userInterfaces/IGovernanceVotePower.sol).

## Functions[​](#functions "Direct link to Functions")

### deposit[​](#deposit "Direct link to deposit")

Deposit native token and mint WNAT ERC-20 to the caller.

```
function deposit() external payable;
```

### withdraw[​](#withdraw "Direct link to withdraw")

Withdraw native token and burn WNAT ERC-20 from the caller.

```
function withdraw(uint256 _amount) external;
```

Parameters:

-   `_amount`: The amount to withdraw.

### depositTo[​](#depositto "Direct link to depositTo")

Deposit native token from `msg.sender` and mint WNAT ERC-20 to `_recipient`.

```
function depositTo(address _recipient) external payable;
```

Parameters:

-   `_recipient`: The address that receives the minted WNAT.

### withdrawFrom[​](#withdrawfrom "Direct link to withdrawFrom")

Withdraw WNAT from `_owner` (subject to allowance) and send the native token to `msg.sender`.

```
function withdrawFrom(address _owner, uint256 _amount) external;
```

Parameters:

-   `_owner`: An address spending the native tokens.
-   `_amount`: The amount to spend.

Requirements:

-   `_owner` must have a balance of at least `_amount`.
-   The caller must have an allowance for `_owner`'s tokens of at least `_amount`.
