We've removed it (getrandom + wasm_js feature) because in some context was causing issues (wasm32-unknown-unknown used outside JS).

You can solve the issue by adding the getrandom dep in your Cargo.toml, and enable the wasm_js feature. Make sure to do it for the right getrandom version(s), which can be found in the Cargo.lock

I've checked the `libnostr_sdk_ffi.so` libraries used in the KMP package and they seem to be correctly aligned:

```text
LOAD off 0x0000000000000000 vaddr 0x0000000000000000 paddr 0x0000000000000000 align 2**14

```

Have you tried verifying whether the APK itself is aligned? From my understanding, the ELF files can be correctly aligned but still be packaged incorrectly inside the APK:

I just took a quick look, and I think the problem is that the relays being added with NONE capabilites. This means they can't do anything (neither read nor write).

Unless you want to use specific capabilities, you can omit that argument in addRelay, so they will be added with the default capabilities (READ + WRITE).

_________________________

I've already adapted FFI APIs but not released anything yet. There are still a some things to rework before the next release.

I think if you fork the repo, you should be able to run the workflow for building them by yourself:

Fork the repo -> Go to "Actions" -> Select the "Publish" workflow -> Click on "Run workflow" -> Select the commit to use, deselect everything except "Build KMP" (the "Swift package version" can be empty) and DON'T select "Publish" -> Run it and you'll find the AAR in the artifacts (called nostr-sdk-ffi-kmp-aar).

Compilation can be done also locally, but unfortunately requires macos as it needs binaries also for iOS, and I didn't found a way to cross-compile them from Linux.

To debug the messages that the client send, you have to enable the debug level: "RUST_LOG=debug cargo run"

You must enable the "env-filter" feature for the tracing-subscriber dependency, to be able use RUST_LOG

Thanks, I'll check it, but I think that it's due to an unreachable relay that has just been added to the pool.
The disconnected relays are skipped (return error instead of waiting) after the second failed attempt.

To confirm it, can you try to decrease the connection timeout, configurable via the Client Builder? (I've added this feature yesterday in master branch).
Or, have you a small code snippet to reproduce it? And what relays did you used?

Regarding the issues, are perfect here on nostr.
But instead of using the text notes, the NIP34 would be better. Here is the repo: https://gitworkshop.dev/yukikishimoto.com/nostr

It currently take at max the first 5 relays from the NIP65 list (I thought I had lowered it to 3, I'll decrease it soon).

But also taking at max 3, the number of connections may be high. Should I lower it to 2?

We've added support for "sleep when idle" for relays (in master branch). I still have to finalize the support in the SDK. With this, the gossip relays (or even all relays) can connect on-demand and sleep when idle.

Another plan is to add a persistent storage for gossip data, give a rank/score to relays... but I still not found the best way to do this. Ideas are appreciated :)

I've reworked the NostrParser at https://github.com/rust-nostr/nostr/pull/899

This improves the performance of ~2x and reduces the final binary size.

I'm merge this soon, if anyone is interested in testing or reviewing the PR, please share a feedback!

## rust-nostr v0.42 is out! 🦀

### Summary

Blossom, NostrMLS, Relay Monitor, NIP-70 support for relay-builder, NIP-46 reworks, some bug fixes and more!

Note for who is interested in NostrMLS: it's not currently available on https://crates.io as it depends on an unreleased version of openmls. However, you can use it directly from git. The bindings will be available in the upcoming releases.

Full changelog: https://rust-nostr.org/changelog

### Bindings specific changes

Added support for event streaming and extended supported OS and architectures.

New supported platforms for Python, C# and JVM bindings:
- Windows x86 and aarch64
- Linux (GLIBC) x86, armv7 and riscv64
- Linux (MUSL) x86, x86_64, armv7, aarch64 and riscv64

I've just published a pre-release for the python nostr-sdk (version `0.42.0a2`), using the ABI3. I've also extended the support to Linux x86, windows x86 and aarch64.

If anyone is interested in trying it, please share a feedback if something doesn't work.

## rust-nostr v0.41 is out! 🦀

### Summary

Added NIP-C0 support and NIP-98 helpers, fixed NIP-32 and NIP-47 implementations, added nostr-keyring crate, extended admission policies for granular control over which relays can connect and which cannot (useful when gossip mode is enabled), enabled POSIX semaphores for LMDB on iOS & macOS to fix issues with App Sandbox, extended arch support for C# and JVM bindings (linux-x86, windows-x86 and windows-arm64) and more!

For those who missed it, from v0.40.0 are available the C# bindings for nostr-sdk:

Because I was using SQLite only for persistence. When it was opened, all the data was loaded into RAM, in the DatabaseHelper. It was basically an in-memory database with SQLite as persistence.

Using the NostrDatabase traits, you can implement your own database, and use it in rust-nostr. But if anyone is interested to open a PR to implement a "pure" SQLite backend, I'll merge it.

justinmoon (nprofile…tknc), yeah, you can use nostrdb APIs directly for the zero-copy queries and nostr-sdk for the networking stuff.

You can eventually clone the nostrdb instance and pass it to nostr-sdk just to automatically save the events received from the relays into nostrdb.

In reply to nevent1q…yzhp
_________________________

I usually copy the stuff I already exposed in the UniFFI bindings and adapt it to the flutter_rust_bridge.

So, in the case of metadata stuff, I would copy and adapt this: https://github.com/rust-nostr/nostr/blob/d7a8372e28a5dd7e1ce02b725ee0b43c798e332f/bindings/nostr-sdk-ffi/src/protocol/nips/nip01.rs

To adapt it, I follow these docs https://cjycode.com/flutter_rust_bridge/ or I just check the other modules I already adapted. In short: replace the uniffi macros with `frb` and use the `Result` from anyhow. If a new module is added, it must be exported in the `lib/nostr_sdk.dart` file.
