BlazeJump provides core protocol interactions through a minimal Nostr client written in C#.
About BlazeJump
BlazeJump is a minimal Nostr client written in C# using Blazor. It has two clients: an Android app and a web client. The Android app stores the user's keypair in Android Secure Storage. The web client uses the NIP46 Nostr Connect protocol to use the Android device as a signer.
The project is described as bare bones, so it covers core protocol interactions rather than a full-featured client. Setup is described as opening the solution in Visual Studio 2022 and running it. The repository is released under the MIT license. The source does not describe any hosted service, website, or topics beyond the repository itself.
