Struct bdk_wallet::descriptor::template::Bip84Public

source ·
pub struct Bip84Public<K: DerivableKey<Segwitv0>>(pub K, pub Fingerprint, pub KeychainKind);
Expand description

BIP84 public template. Expands to wpkh(key/{0,1}/*)

This assumes that the key used has already been derived with m/84'/0'/0' for Mainnet or m/84'/1'/0' for Testnet.

This template requires the parent fingerprint to populate correctly the metadata of PSBTs.

See Bip84 for a template that does the full derivation, but requires private data for the key.

§Example

use bdk_wallet::template::Bip84Public;

let key = bitcoin::bip32::Xpub::from_str("tpubDC2Qwo2TFsaNC4ju8nrUJ9mqVT3eSgdmy1yPqhgkjwmke3PRXutNGRYAUo6RCHTcVQaDR3ohNU9we59brGHuEKPvH1ags2nevW5opEE9Z5Q")?;
let fingerprint = bitcoin::bip32::Fingerprint::from_str("c55b303f")?;
let mut wallet = Wallet::new(
    Bip84Public(key.clone(), fingerprint, KeychainKind::External),
    Bip84Public(key, fingerprint, KeychainKind::Internal),
    Network::Testnet,
)?;

assert_eq!(wallet.next_unused_address(KeychainKind::External).to_string(), "tb1qedg9fdlf8cnnqfd5mks6uz5w4kgpk2pr6y4qc7");
assert_eq!(wallet.public_descriptor(KeychainKind::External).to_string(), "wpkh([c55b303f/84'/1'/0']tpubDC2Qwo2TFsaNC4ju8nrUJ9mqVT3eSgdmy1yPqhgkjwmke3PRXutNGRYAUo6RCHTcVQaDR3ohNU9we59brGHuEKPvH1ags2nevW5opEE9Z5Q/0/*)#dhu402yv");
