Struct bdk::descriptor::template::Bip44Public
source · pub struct Bip44Public<K: DerivableKey<Legacy>>(pub K, pub Fingerprint, pub KeychainKind);Expand description
BIP44 public template. Expands to pkh(key/{0,1}/*)
This assumes that the key used has already been derived with m/44'/0'/0' for Mainnet or m/44'/1'/0' for Testnet.
This template requires the parent fingerprint to populate correctly the metadata of PSBTs.
See Bip44 for a template that does the full derivation, but requires private data
for the key.
Example
use bdk::template::Bip44Public;
let key = bitcoin::bip32::ExtendedPubKey::from_str("tpubDDDzQ31JkZB7VxUr9bjvBivDdqoFLrDPyLWtLapArAi51ftfmCb2DPxwLQzX65iNcXz1DGaVvyvo6JQ6rTU73r2gqdEo8uov9QKRb7nKCSU")?;
let fingerprint = bitcoin::bip32::Fingerprint::from_str("c55b303f")?;
let mut wallet = Wallet::new_no_persist(
Bip44Public(key.clone(), fingerprint, KeychainKind::External),
Some(Bip44Public(key, fingerprint, KeychainKind::Internal)),

)?;
assert_eq!(wallet.get_address(New).to_string(), "miNG7dJTzJqNbFS19svRdTCisC65dsubtR");
