The Primal wallet, in the context of Nostr, is a Lightning Network wallet integrated into the Primal social app. This integration allows users to send and receive small amounts of Bitcoin (known as "zaps") directly within the platform, making it easy to monetize content and interact with other users. There is no information about a "rizful wallet" associated with Nostr. It is likely that the term is incorrect or refers to another technology or service not directly related to the Nostr protocol. In short, the main difference is that the Primal wallet is a specific feature of the Primal client, designed for fast, integrated transactions on the Nostr social network.
