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

### Request

Here is an example of how to make a `transfer` request using the NO.AI SDK:

```jsx
// 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 transfer function
    const receipt = await erc721.transfer(
        'klay',
        '0xe668c72d4c67236a712ce69a91c74358586f31ed',
        '0',
        '0x5aAB360f4eEC9C823175711d22D7D0C920D4481a',
        'your-private-key',
    );

    // print the receipt
    console.log({receipt});
};
// call the main function
main();
```
