Crate rustywallet_taproot 

rustywallet-taproot

Full Taproot support implementing BIP340 (Schnorr), BIP341 (Taproot), and BIP342 (Tapscript).

Features

• Schnorr signatures (BIP340)
• X-only public keys
• Key tweaking for Taproot
• Tap tree (MAST) construction
• Control block generation
• P2TR address generation
• BIP341 signature hash

Example

use rustywallet_taproot::{XOnlyPublicKey, TaprootOutput, Network};
use secp256k1::{Secp256k1, SecretKey};

// Generate a key pair
let secp = Secp256k1::new();
let secret = [1u8; 32];
let sk = SecretKey::from_slice(&secret).unwrap();
let pk = sk.public_key(&secp);
let (xonly, _) = pk.x_only_public_key();
let internal_key = XOnlyPublicKey::from_inner(xonly);

// Create a key-path only Taproot output
let output = TaprootOutput::key_path_only(internal_key).unwrap();

// Get the P2TR address
let address = output.address(Network::Mainnet).unwrap();
assert!(address.starts_with("bc1p"));

Script Path Example

use rustywallet_taproot::{XOnlyPublicKey, TaprootOutput, TapTreeBuilder, Network};
use secp256k1::{Secp256k1, SecretKey};

let secp = Secp256k1::new();
let secret = [1u8; 32];
let sk = SecretKey::from_slice(&secret).unwrap();
let pk = sk.public_key(&secp);
let (xonly, _) = pk.x_only_public_key();
let internal_key = XOnlyPublicKey::from_inner(xonly);

// Build a tap tree with two scripts
let tree = TapTreeBuilder::new()
    .add_leaf(1, vec![0x51]) // OP_1
    .add_leaf(1, vec![0x52]) // OP_2
    .build()
    .unwrap();

// Create output with script tree
let output = TaprootOutput::with_script_tree(internal_key, &tree).unwrap();
let address = output.address(Network::Mainnet).unwrap();
