## Read-Only Functions

**getAirdropStat**

```solidity
function getAirdropStat() external view returns (
    uint256 totalAmount,
    uint256 blockAmount,
    uint256 distributableBlock,
    uint256 endBlock,
    uint256 distributed,
    uint256 remain,
    bool created
) 
```

**Return Values:**

<table><thead><tr><th width="239.66666666666663">Name</th><th width="107">Type</th><th>Description</th></tr></thead><tbody><tr><td><code>totalAmount</code></td><td>uint256</td><td>The total amount of airdrop</td></tr><tr><td><code>blockAmount</code></td><td>uint256</td><td>The airdroped amount of token per block</td></tr><tr><td><code>distributableBlock</code></td><td>uint256</td><td>The block number of available block</td></tr><tr><td><code>endBlock</code></td><td>uint256</td><td>The block number of airdrop ended</td></tr><tr><td><code>distributed</code></td><td>uint256</td><td>The amount of current distributed</td></tr><tr><td><code>remain</code></td><td>uint256</td><td>The amount of remained</td></tr><tr><td><code>created</code></td><td>bool</td><td>intialized</td></tr></tbody></table>

**getDistributionId**

```solidity
function getDistributionId() public view returns (bytes32 id)
```

**Return Values:**[**​**](https://docs.uniswap.org/contracts/v3/reference/periphery/NonfungiblePositionManager#parameters)

<table><thead><tr><th width="119.66666666666666">Name</th><th width="116">Type</th><th>Description</th></tr></thead><tbody><tr><td><code>id</code></td><td>bytes32</td><td>The ID of the distribution</td></tr></tbody></table>
{% endtab %}

{% tab title="State-Changing Functions" %}

## **State-Changing Functions**

**changeNextOwner**

```solidity
function changeNextOwner(address _nextOwner) external
```

**changeOwner**

```solidity
function changeOwner() external
```

**createDistribution**

```solidity
function createDistribution(
    uint256 totalAmount,
    uint256 blockAmount,
    uint256 startBlock
) external
```

**Parameters:**

<table><thead><tr><th width="175.66666666666666">Name</th><th width="102">Type</th><th>Description</th></tr></thead><tbody><tr><td><code>totalAmount</code></td><td>uint256</td><td>Total number of tokens to be distributed by airdrop</td></tr><tr><td><code>blockAmount</code></td><td>uint256</td><td>Token quantity to be distributed per block</td></tr><tr><td><code>startBlock</code></td><td>uint256</td><td>Airdrop start block number</td></tr></tbody></table>

**deposit**

```solidity
function deposit(uint256 amount) external
```

If there is an issue of token exhaustion or extension during the airdrop process, tokens can be recharged using the AirdropOperator's Deposit function.

* When executing the function, transfer more than the amount of tokens entered into the wallet.
* The token specified when creating the operator is charged.
* When recharging due to exhaustion, it will be applied from the block after recharging.

**refixBlockAmount**

```solidity
function refixBlockAmount(uint256 blockAmount) external
```

* Modify the amount of tokens distributed per block
* It is applied from the block after the transaction is executed.

**withdraw**

```solidity
function withdraw(address _token) external
```

* The remaining tokens can be withdrawn after the Airdrop plan is in progress.
* Withdrawal will be made to the owner's account.
