Introducing Primal for iOS

What happens when you integrate a Nostr client with a bitcoin lightning wallet? They both get massively better! Social interactions benefit from seamless micropayments, while the wallet is able to tap into the massive address book represented by the Nostr social graph. This makes it possible to interact with people around the world in totally new ways. For example, Markus from Germany can zap a note posted by Isabella in Costa Rica, who can then buy a coffee with those sats, all from the same app.

At Primal, our goal is to deliver products that have mass appeal; products that can be easily used by anyone. Our latest iOS release represents our best take on how to build on open protocols and balance the tradeoffs between user sovereignty, user experience and ease of use. We believe that Nostr and Bitcoin will grow to billions of users, and we are building the technology that will help onboard and delight everyone.

Nostr Onboarding

Our goal is to achieve the highest level of user experience on a decentralized network, without sacrificing user sovereignty over their account, connections, and content. Therefore the onboarding process needs to be smooth and resemble what users are used to on legacy platforms, while providing access to their Nostr keys:

The user is able to sign up and start using Nostr quickly and without friction. Their key is available in the Account Settings, providing complete control over their Nostr account. In addition, the user can specify the set of Nostr relays they wish to publish to. The Primal iOS app signs all content with the user’s key and publishes it directly to the specified set of relays. This achieves full user control over their Nostr account, social connections, and the content they publish.

Performance & UX

In order to compete with the centralized legacy platforms, we must match and exceed their level of user experience. Interfaces must load quickly and completely, otherwise people will lose interest and Nostr will see a high degree of user churn. With this in mind, we built the Nostr caching service, and open sourced it so that other Nostr developers can leverage it as well. This enables us to provide the types of user experiences that are expected by most people today:

For details about our caching approach please refer to my Nostrasia presentation.

Primal Wallet

We are psyched to introduce Primal Wallet, an insanely easy-to-use transactional wallet, ideal for holding small amounts of bitcoin and making payments on the lightning network.

Strike is providing custody, fiat conversions, and lightning network connectivity to Primal users. By integrating with Strike, we are able to provide uninterrupted service to U.S. and international customers.

Smooth onboarding and wallet operation are essential for our use case. Given that we are dealing with very small amounts, we decided to take the custodial approach. This sacrifices direct user custody over the funds, but makes the overall UX seamless and reliable. New users are able to send and receive sats as soon as they download the app.

Here are a few additional points to keep in mind:

1. <ins>In-App Purchases</ins>: Once the wallet is activated, it is fully-operational and able to receive sats. If the user doesn’t own any sats, they are able to buy small amounts via an in-app purchase, in $5 increments. Note that these purchases are subject to “Apple tax” (15% in U.S. and Canada, 30% elsewhere, for customers with iOS devices), plus 1% Strike margin. Primal does not make any revenue on these purchases. Users can always buy sats through a different method and send them to their Primal Wallet. The in-app purchase is merely a convenient way for new users to get started with small amounts.

2. <ins>Maximum Wallet Balance</ins>: Primal Wallet is designed for holding and transacting with small amounts of bitcoin. Larger amounts should be kept in self custody, preferably on a hardware wallet. To encourage self custody for larger amounts, we are enforcing a maximum wallet balance of 1,000,000 sats (approximately USD $400 at the time of this writing).

We believe that Primal Wallet offers the best tradeoff balance for our use case, including social media zaps, and small purchases: coffee, beer, lunch, etc. We are planning to expand the feature set of the wallet in the upcoming releases, based on the feedback from our users.

Open Networks Win

Nostr is an open network, not controlled by any person, company, nor organization. Anyone can join without asking for permission, and any developer is free to build on it. In a short amount of time, hundreds of projects have sprouted building on Nostr, including: Damus, Amethyst, Snort, Highlighter, Alby, Nos, Mutiny, Coracle, ZBD, Fountain, Habla.news, Plebstr, Spring, Iris, Nostrgram, Current, Blogstack, Zap.stream, Listr, Nostr.band, Nostr.build, Flycat, Nosta.me, NoStrudel, Nostur, Nostore, Zaplife, Wavlake, and many more.

Your Nostr keys work with Primal, as well as every other app in the Nostr ecosystem. You can seamlessly use your Nostr identity in social media apps, blog/news sites, marketplaces, etc. Every Nostr product brings more users and more gravity to the entire network. This is why we believe that Nostr will eventually connect everybody.

If you are not satisfied with the status quo dictated by the legacy media complex, if you think that the global town square should not be owned by anyone, if you feel that people should be in control over their online identity, social connections, and the content they publish - you do have a choice. Join us on Nostr. 🤙💜
