    ```

## serialize\_pczt

Serialize a PCZT to bytes.

<Tabs>
  <Tab title="TypeScript">
    ```typescript theme={null}
    function serialize_pczt(pczt: WasmPczt): Uint8Array

    // Or to hex
    const hex = pczt.to_hex();
    ```
  </Tab>

## Use Cases

### Transmit to External Signer

```typescript theme={null}
// Serialize for transmission
const pcztBytes = t2z.serialize_pczt(pczt);
const pcztBase64 = btoa(String.fromCharCode(...pcztBytes));

// Send to signer...
const signedBase64 = await sendToSigner(pcztBase64);

// Parse signed PCZT
const signedBytes = Uint8Array.from(atob(signedBase64), c => c.charCodeAt(0));
const signedPczt = t2z.parse_pczt(signedBytes);
```

### Store and Resume

```typescript theme={null}
// Save to storage
localStorage.setItem('pczt', pczt.to_hex());

// Later, resume
const pczt = WasmPczt.from_hex(localStorage.getItem('pczt'));
```
