# Read static content from chain

To access content stored on-chain, use the `payload_transaction_id` returned when the content was uploaded. If the content is encrypted, provide the password or AES key in the options.

<pre class="language-javascript"><code class="lang-javascript">import {BlocknoteReader} from "blocknote" 

const options = {};
const reader  = new BlocknoteReader(
<strong>    "7VR62WIMCSA5POMS2QAY64SMKW5GBTN2WCBTNA5H4W3WFMYLFHWQ",
</strong><strong>    options   
</strong>);

reader.read().then((response) => {    
    console.log(response);
});
</code></pre>
