silent-tweak-sdk

Zero-trust BIP352 Silent Payment client SDK.

The scan key (b_scan) never leaves the client. All cryptographic derivation happens locally. The remote server is treated as an untrusted tweak provider: its data is always verified against a Merkle commitment before use.

Quick start

use silent_tweak_sdk::{SilentTweakClient, SilentTweakClientConfig, ScanKeys};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let keys = ScanKeys::from_secret_bytes(
        &hex::decode("b_scan_hex_here").unwrap(),
        &hex::decode("b_spend_hex_here").unwrap(),
    )?;
    let cfg = SilentTweakClientConfig::new("http://localhost:8080");
    let client = SilentTweakClient::new(keys, cfg)?;
    let outputs = client.scan_range(840_000, 840_100).await?;
    println!("Found {} matching outputs", outputs.len());
    Ok(())
}
