Share file on Arcana Store

In this tutorial you will learn how to use Arcana Storage SDK and share a file that was earlier uploaded to Arcana Store by the current dApp user with another user.


  • Make sure your dApp is integrated with Arcana Storage SDK
  • You need to have access to the target user's wallet address for authenticating and enabling file sharing permissions
  • The DID of the file is required in order to share file access and identify it uniquely on the Arcana Store
  • The code in the steps section below refers to StorageProvider and Access objects initialized during Storage SDK integration:
import { StorageProvider } from '@arcana/storage/dist/standalone/storage.umd';

dAppStorageProvider = new StorageProvider({
provider: window.ethereum,
email: user_email_string,

const Access = new dAppStorageProvider.getAccess();

Share file access

// did: DID of file to be shared
// address: recipients address
// validity (optional): For how long will be the user able to download the file, e.g. [400] would mean 400 seconds
Access.share([did], [address]);

What's Next?

You can also change file ownership or revoke file access using Storage SDK.

If you are using Storage SDK with a third party wallet, you can also consider integrating with Arcana Auth SDK to ensure the privacy of your data by encrypting data before uploading and decrypting data after download.
