# ⚙️ Integrate with MonoX

The MonoX smart contracts *will* exist on the Ethereum blockchain. Until that time, there are a bunch of test networks are available for you to integrate and complete your tests. These networks are:

* Ethereum Mainnet,
* Polygon Mainnet,
* Kovan Testnet,
* Mumbai Test (Polygon)

## Contracts

In order to complete an integration with the below contracts, you will need to have ABI ([Application Binary Interface](https://en.wikipedia.org/wiki/Application_binary_interface)). 

#### How to get ABI of a contract?

## Integration 

Our Monoswap contract ([`kovan`](https://kovan.etherscan.io/address/0xE8141055b060BA9f7C75c6D5c904D4A7Fc97A66b)  or [`mumbai`](https://mumbai.polygonscan.com/address/0xf0086a7bF26E4be27D6bF2d9f9f108F321cc72E7)) has some core features available for the developers who are interested in using them externally.

#### What type of functions is available for a contract?

![Visit a contract link above, click into the Contract tab,  then select Write as Proxy to see all functions.](https://2781113920-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-MR_I-JDXtJWdahcdstl%2F-MkMDltHNpyO9o0S3ahf%2F-MkMKFhiSKL6pMeK11Xp%2FContractFunctions.gif?alt=media\&token=da419b7b-a6f2-4c43-a681-653d304c0e80)

### MonoX Core Functionalities

Some of the key functionalities we offer are: 

* `listNewToken`, 
* `addLiquidity`, 
* `addLiquidityETH`, 
* `removeLiquidity`,
* `swapExactTokenForToken` and `swapTokenForExactToken,`
* `swapExactETHForToken`, `swapExactTokenForETH`, `swapETHForExactToken` and `swapTokenForExactETH`

{% hint style="warning" %}
`listNewToken`, `addLiquidity`, `swapExactTokenForToken` and `swapTokenForExactToken` requires that the token has been approved in advance.
{% endhint %}

#### `listNewToken`

This function list tokens and adds liquidity with `vcashAmount` and `tokenAmount` then sends LP tokens to `to` address. So, the user can list a new token. 

```javascript
function listNewToken (
        address _token,        // Token address to list
        uint _price,           // Token price
        uint256 vcashAmount,   // VCASH amount to add initially
        uint256 tokenAmount,   // Token amount to add initially
        address to             // Address that gets liquidity
        )           
```

#### `addLiquidity`

This function adds liquidity to an ERC-20⇄ERC-20 pool. So, users can contribute into the pool.

```javascript
function addLiquidity (
        address _token,        // Token address
        uint256 _amount,       // Token amount to add
        address to             // Address to send LP token 
        )
```

#### `addLiquidityETH`

This function adds liquidity to an ERC-20⇄WETH pool with ETH. So, users can add liquidity to the ETH pool.

```javascript
function addLiquidityETH (
        address to             // Address to send LP token  
        )
```

#### `removeLiquidity`

This function removes liquidity to an ERC-20⇄ERC-20 pool. 

```javascript
function removeLiquidity (
        address _token,        // Token address
        uint256 liquidity,     // Liquidity
        address to,            // Token amount to add
        uint256 minVcashOut,   // The minimum amount of VCash that must be received
        uint256 minTokenOut    // The minimum amount of Token that must be received
        )
```

For removing ETH liquidity, use `removeLiquidityETH` function. It removes liquidity to an ERC-20⇄WETH pool with ETH.

#### `swapExactTokenForToken`

Users can swap tokens using `swapExactTokenForToken`. So, user's input token is known and the output token is calculated `swapTokenForExactToken`.

```javascript
function swapExactTokenForToken(
        address tokenIn,       // Input token address
        address tokenOut,      // Output token address
        uint amountIn,         // The amount of input tokens to send
        uint amountOutMin,     // The minimum amount of output tokens that must be received for the transaction not to revert
        address to,            // Recipient of the output tokens
        uint deadline          // Unix timestamp after which the transaction will revert
        )
```

#### `swapTokenForExactToken`

Users can swap tokens using `swapTokenForExactToken`. So, user's output token is known and the input token is calculated.

```javascript
 function swapTokenForExactToken(
        address tokenIn,       // Input token address
        address tokenOut,      // Output token address
        uint amountInMax,      // The maximum amount of input tokens that can be required before the transaction reverts
        uint amountOut,        // The amount of output tokens to receive
        address to,            // Recipient of the output tokens
        uint deadline          // Unix timestamp after which the transaction will revert
        )
```

For swapping ETH, please use one of below functions:

{% tabs %}
{% tab title="swapExactETHForToken" %}

```javascript
function swapExactETHForToken(
        address tokenOut,      // Output token address
        uint amountOutMin,     // The minimum amount of output tokens that must be received for the transaction not to revert
        address to,            // Recipient of the output tokens
        uint deadline          // Unix timestamp after which the transaction will revert
        )
```

{% endtab %}

{% tab title="swapExactTokenForETH" %}

```javascript
function swapExactTokenForETH(
        address tokenIn,       // Input token address
        uint amountIn,         // The amount of input tokens to send
        uint amountOutMin,     // The minimum amount of output tokens that must be received for the transaction not to revert
        address to,            // Recipient of the output tokens
        uint deadline          // Unix timestamp after which the transaction will revert
        )
```

{% endtab %}

{% tab title="swapETHForExactToken" %}

```javascript
function swapETHForExactToken(
        address tokenOut,      // Output token address
        uint amountInMax,      // The maximum amount of input tokens that can be required before the transaction reverts
        uint amountOut,        // The amount of output tokens to receive
        address to,            // Recipient of the output tokens
        uint deadline          // Unix timestamp after which the transaction will revert
        )
```

{% endtab %}

{% tab title="swapTokenForExactETH" %}

```javascript
function swapTokenForExactETH(
        address tokenIn,       // Input token address
        uint amountInMax,      // The maximum amount of input tokens that can be required before the transaction reverts  
        uint amountOut,        // The amount of output tokens to receive
        address to,            // Recipient of the output tokens
        uint deadline          // Unix timestamp after which the transaction will revert      
        )
```
