</Note>

**Deposit with Exchange** gives your users a seamless way to fund their connected wallets directly from centralized exchange accounts like Binance. Instead of forcing users to leave your app, log into their exchange, and manually handle withdrawals, you can offer a guided in-app flow that keeps them engaged and ready to transact.

## Quickstart 

This feature will start working as soon as your team is on the allowed-list. Contact us [via our form here](https://share.hsforms.com/1_oWa8QkwRXi6oR0nZ_SIxQnxw6s) to get started.

<Warning>
    Projects first need to install and set up Reown AppKit before integrating AppKit Pay. If you haven't done so, please refer to the [Reown AppKit docs](/appkit/overview#quickstart).
</Warning>

Clicking on Fund your wallet will show the modal below:

### Install the library

<CodeGroup>

```bash npm
npm install @reown/appkit-pay
```

```bash Yarn
yarn add @reown/appkit-pay
```

```bash Bun
bun a @reown/appkit-pay
```

```bash pnpm
pnpm add @reown/appkit-pay
```
</CodeGroup>

### Usage
Import the `baseUSDC` asset, the `pay` function and the `useAppKitAccount` hook to get the address of the connected wallet.
```ts

import { baseUSDC, pay } from '@reown/appkit-pay';
```

Get the address of the connected wallet using the `subscribeAccount` function.
```ts
let address = null;
const appKit = createAppKit({...}); // please check our docs or examples to understand how to create the AppKit instance
appKit.subscribeAccount(state => {
    address = state['accountState']?.address;
})
```

In order to run the deposit, use the function `pay`. This function receives three parameters.

```ts
// pay function returns a PaymentResult object
const result = await pay({ 
    recipient: address,
    amount: 0.0001,
    paymentAsset: baseUSDC
});

if (result.success) {
    console.log("Payment successful: "+ result.result);
} else {
    console.error("Payment error: "+ result.error);
}
```

    metadata: {
        name: 'Ethereum', // Or 'USD Coin'
        symbol: 'ETH',    // Or 'USDC'
        decimals: 18      // Or 6 for USDC
    }
};
```
