Struct bdk::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::template::Bip84Public;
let key = bitcoin::bip32::ExtendedPubKey::from_str("tpubDC2Qwo2TFsaNC4ju8nrUJ9mqVT3eSgdmy1yPqhgkjwmke3PRXutNGRYAUo6RCHTcVQaDR3ohNU9we59brGHuEKPvH1ags2nevW5opEE9Z5Q")?;
let fingerprint = bitcoin::bip32::Fingerprint::from_str("c55b303f")?;
let mut wallet = Wallet::new_no_persist(
Bip84Public(key.clone(), fingerprint, KeychainKind::External),
Some(Bip84Public(key, fingerprint, KeychainKind::Internal)),
Network::Testnet,
)?;
assert_eq!(wallet.get_address(New).to_string(), "tb1qedg9fdlf8cnnqfd5mks6uz5w4kgpk2pr6y4qc7");
