Struct bdk_wallet::descriptor::template::Bip44Public

pub struct Bip44Public<K: DerivableKey<Legacy>>(pub K, pub Fingerprint, pub KeychainKind);

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_wallet::template::Bip44Public;

let key = bitcoin::bip32::Xpub::from_str("tpubDDDzQ31JkZB7VxUr9bjvBivDdqoFLrDPyLWtLapArAi51ftfmCb2DPxwLQzX65iNcXz1DGaVvyvo6JQ6rTU73r2gqdEo8uov9QKRb7nKCSU")?;
let fingerprint = bitcoin::bip32::Fingerprint::from_str("c55b303f")?;
let mut wallet = Wallet::create(
    Bip44Public(key.clone(), fingerprint, KeychainKind::External),
    Bip44Public(key, fingerprint, KeychainKind::Internal),
    )
    .network(Network::Testnet)
.create_wallet_no_persist()?;

assert_eq!(wallet.next_unused_address(KeychainKind::External).to_string(), "miNG7dJTzJqNbFS19svRdTCisC65dsubtR");
assert_eq!(wallet.public_descriptor(KeychainKind::External).to_string(), "pkh([c55b303f/44'/1'/0']tpubDDDzQ31JkZB7VxUr9bjvBivDdqoFLrDPyLWtLapArAi51ftfmCb2DPxwLQzX65iNcXz1DGaVvyvo6JQ6rTU73r2gqdEo8uov9QKRb7nKCSU/0/*)#cfhumdqz");
