A high-level, Nostr client library written in Rust.
If you're writing a typical Nostr client or bot, this is likely the crate you need.
However, the crate is designed in a modular way and depends on several other lower-level crates. If you're attempting something more custom, you might be interested in these:
nostr: Rust implementation of Nostr protocol.toml
[dependencies]
nostr-sdk = "0.10"
tokio = { version = "1", features = ["full"] }
```rust,no_run use std::net::{Ipv4Addr, SocketAddr, SocketAddrV4};
use nostrsdk::nostr::{Keys, Metadata}; use nostrsdk::nostr::url::Url; use nostr_sdk::{Client, Result};
async fn main() -> Result<()> { // Generate new keys let mykeys: Keys = Client::generatekeys(); // // or use your already existing // // From HEX or Bech32 // use nostrsdk::nostr::key::FromSkStr; // let mykeys = Keys::fromskstr("hex-or-bech32-secret-key")?; // // From Bech32 // use nostrsdk::nostr::key::FromBech32; // let mykeys = Keys::frombech32("nsec1...")?; // // From HEX // use std::str::FromStr; // use nostrsdk::nostr::secp256k1::SecretKey; // let secretkey = SecretKey::fromstr("hex-secret-key")?; // let mykeys = Keys::frombech32("nsec1...")?;
// Create new client
let client = Client::new(&my_keys);
let proxy = Some(SocketAddr::V4(SocketAddrV4::new(Ipv4Addr::LOCALHOST, 9050)));
// Add relays
client.add_relay("wss://relay.damus.io", None).await?;
client.add_relay("wss://relay.nostr.info", proxy).await?;
client.add_relay(
"ws://jgqaglhautb4k6e6i2g34jakxiemqp6z4wynlirltuukgkft2xuglmqd.onion",
proxy,
).await?;
// Connect to relays and keep connection alive
client.connect().await?;
let metadata = Metadata::new()
.name("username")
.display_name("My Username")
.about("Description")
.picture(Url::parse("https://example.com/avatar.png")?)
.nip05("username@example.com")
.lud16("yuki@stacker.news");
// Update profile metadata
client.update_profile(metadata).await?;
// Publish a text note
client.publish_text_note("My first text note from Nostr SDK!", &[]).await?;
// Publish a POW text note
client.publish_pow_text_note("My first POW text note from Nostr SDK!", &[], 20).await?;
// Handle notifications
loop {
let mut notifications = client.notifications();
while let Ok(notification) = notifications.recv().await {
println!("{:?}", notification);
}
}
} ```

The following crate feature flags are available:
| Feature | Default | Description |
| ------------------- | :-----: | -------------------------------------------------------------------------------------------------------------------------- |
| blocking | No | Needed to use this library in not async/await context |
| all-nips | Yes | Enable all NIPs |
