            amount: "20000000"
        }
    ]
});

const tx = await waitForTransaction(
    boc,
    client,
    10, // retries
    1000, // timeout before each retry
);

if (tx) {
    console.log('Found transaction:', tx);

--------------------------------

### Set Connect Request Parameters (ton_proof)

Source: https://ton-connect.github.io/sdk/modules/_tonconnect_ui.html

Use `tonConnectUI.setConnectRequestParameters` to manage parameters for the `ton_proof` request. This allows you to set a loading state while waiting for backend responses, provide the `tonProof` payload, or remove the loader.

```APIDOC
## Add connect request parameters (ton_proof)

Use `tonConnectUI.setConnectRequestParameters` function to pass your connect request parameters.
This function takes one parameter:
Set state to 'loading' while you are waiting for the response from your backend. If user opens connect wallet modal at this moment, he will see a loader.

```typescript
tonConnectUI.setConnectRequestParameters({
    state: 'loading'
});
```

or
Set state to 'ready' and define `tonProof` value. Passed parameter will be applied to the connect request (QR and universal link).

```typescript
tonConnectUI.setConnectRequestParameters({
    state: 'ready',
    value: {
        tonProof: '<your-proof-payload>'
    }
});
```

or
Remove loader if it was enabled via `state: 'loading'` (e.g. you received an error instead of a response from your backend). Connect request will be created without any additional parameters.

```typescript
tonConnectUI.setConnectRequestParameters(null);
```

You can call `tonConnectUI.setConnectRequestParameters` multiple times if your tonProof payload has bounded lifetime (e.g. you can refresh connect request parameters every 10 minutes).

```typescript
// enable ui loader  
tonConnectUI.setConnectRequestParameters({ state: 'loading' });  
  
// fetch you tonProofPayload from the backend  
const tonProofPayload: string | null = await fetchTonProofPayloadFromBackend();  
  
if (!tonProofPayload) {  
    // remove loader, connect request will be without any additional parameters  
    tonConnectUI.setConnectRequestParameters(null);  
} else {  
    // add tonProof to the connect request  
    tonConnectUI.setConnectRequestParameters({  
        state: "ready",  
        value: { tonProof: tonProofPayload }  
    });  
}
```

You can find `ton_proof` result in the `wallet` object when wallet will be connected:

```typescript
tonConnectUI.onStatusChange(wallet => {
        if (wallet && wallet.connectItems?.tonProof && 'proof' in wallet.connectItems.tonProof) {
            checkProofInYourBackend(wallet.connectItems.tonProof.proof);
        }
    });
```
```

--------------------------------

### Set Connect Request Parameters with Ton Proof

Source: https://ton-connect.github.io/sdk/modules/_tonconnect_ui.html

tonConnectUI.setConnectRequestParameters({
    state: 'ready',
    value: {
        tonProof: '<your-proof-payload>'
    }
});
```
