## Example Request and Response

### Prerequisites

Before making requests with Volary SDK, you must have it installed.

You can install Volary SDK using either **`npm`** or **`yarn`**. Use the following commands to install Volary SDK:

```
npm install @nest25/evm-chains-lib
OR
yarn add @nest25/evm-chains-lib
```

### Request

Here is an example of how to make a `deployContract` request using the Volary SDK:

```javascript
// import the Nest SDK
const { ERC721 } = require('@nest25/evm-chains-lib');

// create a new instance of the ERC721 class
const erc721 = new ERC721();

// define the main function
const main = async () => {
    // call the deployContract function
    const contract = await erc721.deployContract(
        'klay',
        'your-private-key',
        'testErc721',
        'TEST',
    );

    // print the contract address and transaction hash
    console.log(`Contract deployed at ${contract.address}. Transaction hash: ${contract.deployTransaction.hash}`);
};
// call the main function
main();
```

### Response

```
Contract deployed at 0x6e94C8C4AE6DaE35dAA4f51B448Dbbf03C70890a. Transaction hash: 0xc9824dd43296e500cdd09aecb6e0cb85eac0255bbb3505856a31a9da2b394a60
```

## Use Cases
