First Wave of Nostr Grants


The mission of OpenSats is to support and maintain a sustainable ecosystem of funding for free and open-source projects that help Bitcoin flourish. Nostr is such a project, which is why OpenSats introduced The Nostr Fund and built a team around the protocol's originator to help fund the growing nostr ecosystem. As an open, interoperable, and censorship-resistant protocol, nostr has the chance of doing social-native networking right.

After weeks of sorting through applications, we are excited to announce the first round of grants from The Nostr Fund. OpenSats is proud to support over a dozen projects, from clients to relay implementations to adjacent tools and design efforts.

In no particular order, here they are:

The projects above have received grants of various durations and sizes, and we have more nostr-related applications in the pipeline. Donate to The Nostr Fund if you want to help fund the nostr ecosystem.

Without further ado, let's take a closer look at each project in turn.


NDK is a nostr development kit that makes the experience of building Nostr-related applications—whether they are relays, clients, or anything in between—better, more reliable, and overall more enjoyable to work with than existing solutions. The core goal of NDK is to improve the decentralization of Nostr via intelligent conventions and data discovery features without depending on any one central point of coordination, such as large relays or centralized search providers.

Habla is a website for reading, writing, curating, and monetizing long-form content on nostr. It uses NIP-23 to allow markdown-formatted articles and embedded nostr content such as notes, profiles, lists, relays, badges, and more. The goal of Habla is to give everyone an alternative to centralized publishing platforms such as Medium or Substack, which are by their very nature prone to censorship and deplatforming.

Coracle is a nostr web client focusing on user experience, performance, and scaling of the nostr network beyond the "twitter clone" use-case. The end goal is to build marketplaces, groups, chat, and more on top of an emergent web of trust. Coracle is already one of the most mature and accessible clients for new users while also providing some novel features for more advanced nostriches.

Iris is a multi-platform nostr client that is available for web, mobile, and desktop. Iris' design goals are speed, reliability, and ease of use. The client features public as well as private messaging, customizable feeds, an offline mode, and speedy account creation.

Damus is a cutting-edge nostr client for iOS. The goal of Damus is to integrate bitcoin with social media and to show the power, censorship resistance, and scalability of nostr in general. Damus includes picture and video uploading, is fully translated into 24 languages, supports automatic translation of notes, and includes all of the features you would expect from a Twitter-like client.

rust-nostr & nostr-sdk

Rust-nostr is a Rust implementation of the nostr protocol. It is a high-level client library with the explicit goal to help developers build nostr apps for desktop, web, and mobile that are both fast and secure. Rust crates can be easily embedded inside other development environments like Swift, Kotlin, Python, and JavaScript, making rust-nostr a versatile base to build upon. While the project is in the early stages of development, over 35 NIPs are already supported, with more to come.

Nostr Relay NestJS

Nostr-relay-nestjs is a Nostr relay with a clear structure that is easy to customize to your needs. This relay implementation is based on the NestJS framework and focuses on reliability and high test coverage.

Soapbox started out as an alternative to Mastodon but has grown to encompass ActivityPub and nostr while being interoperable with both. In February 2023, the team launched the "Mostr" bridge, seamlessly connecting nostr to the ActivityPub Fediverse and enabling bidirectional communication between both protocols. This bridge exposes over 9.4M potential users in nostr's target audience to nostr, many of whom have already left the Fediverse completely in favor of nostr.

Code Collaboration over Nostr

This project is a proof-of-concept for a much-needed, often discussed, and permissionless, nostr-based GitHub alternative. The goal is to replace the traditional interactions using a centralized server or service with a nostr-based alternative centered around nostr events. Commits, branches, pull requests, and other actions are all modeled as nostr events, with permissions managed through groups so that multiple maintainers can manage a repository. This model reduces the barriers for clients to support repository collaboration and allows for interoperability between repository management tools.

Satellite is a web client for nostr that has a community focus and presents conversations as threaded comments, borrowing from the traditional Reddit interface.

Amethyst is one of the most popular nostr clients for Android. Amethyst comes with expected features such as account management, feeds, profiles, and direct messages. Amethyst also offers native image uploads, public chat groups, link previews, one-tap zaps, public and private bookmarks, as well as the ability to follow hashtags, and other novel features. You can install releases of Amethyst via F-Droid or Google Play.

Pinstr allows users to easily organize and discover new ideas by creating public boards of pins. Users can star, comment, and zap other users' boards. Users can find curated boards of other users and create boards themselves. Default boards include users' bookmarked content, among other lists.

Repository: sepehr-safari/pinstr
License: MIT is a free-to-use media hosting service that allows users to upload images, gifs, videos, and audio files to share them as nostr events. The team recently released their code under an MIT License so that anyone might use the software to offer a similar service.

Gossip is a fast and stable desktop nostr client focused on the Twitter-like micro-blogging aspect of nostr. Gossip follows people by downloading their events from whichever relays they post to (rather than relays you configure) and was the impetus for NIP-65. It does not use complex web technologies such as JavaScript or HTML rendering and stores your private key only in an encrypted format. Consequently, Gossip is considered more secure than other clients by some. The client is packaged and released for Linux, Windows, and MacOS.

Nostr SDK iOS

The nostr SDK for iOS is a native Swift library that will enable developers to quickly and easily build nostr-based apps for Apple devices. The library plans to implement all approved NIPs and will follow Apple's API patterns, so that iOS developers feel comfortable using it from the start. The SDK aims to be simple in its public interface, abstracting away as much complexity as possible so that developers can focus on what makes their specific application unique.

Nostr Design

Nostr Design will be a comprehensive resource for designers and developers to build successful nostr products. Nostr introduces several new concepts that most people are not familiar with. Given its nature, the protocol presents some unique design challenges for developers and users alike. The Nostr Design efforts are led by Karnage, who has done stellar product design work around nostr in the past. We believe that this project has the potential to impact the entire nostr space, as it can act as a go-to source for developing quality products, addressing user needs, as well as providing concrete examples and building blocks for product designers and developers alike.

We have received hundreds of applications in the last couple of weeks, many related to or exclusively focused on nostr. Most projects that applied focus on bitcoin and lightning. We will announce another wave of grants for these soon.

To all the nostr projects that applied and didn't make the cut this time around: don't be discouraged. Please apply for funding again in the future. We will announce new grants and funding opportunities quarterly, and there is always the possibility of being listed on the OpenSats website to receive pass-through donations for your project.

We are excited to support the projects above in building the tools we bitcoiners care so deeply about. The future is bright; we just have a lot of building to do.
