3. Scan the QR Code (For Printed Documents)

Documents signed within Twala contain a QR code in their audit trail, making printed documents easy to verify.

You will be redirected to the Twala website, where the document’s verification result will be displayed.

4. Command Line Interface (CLI) — For Developers

Advanced users or businesses can verify documents using the Twala CLI (Command Line Interface).

Twala stores document hashes on the Ethereum blockchain using a process called Chained Anchoring, making it virtually impossible to alter verified documents.

Steps:

  • Install the Twala CLI NPM package: npm install @twala-io/twala-cli

  • Follow the CLI documentation on our NPM page.

  • Use the CLI to generate the document hash and cross-check it with the blockchain record.

  • Owner of the Document (Sender)

  • Digital Timestamp

  • List of Signatories (with their Twala ID, email, and IP address if available)

  • Blockchain Block Number

  • Transaction Hash

When you have a verified document, it looks like this:
