Standards and Protocols

Paradym is built on open standards and protocols. For a truly interoperable internet, open standards and protocols are essential.


When using Paradym and the Paradym Wallet, the standards and protocols on this page are supported out of the box and no additional configuration is required on your end. If you're building a custom holder wallet that needs to interact with Paradym, see the Integrating with a Holder Wallet page for more information.
