Struct bdk_wallet::descriptor::template::Bip84

pub struct Bip84<K: DerivableKey<Segwitv0>>(pub K, pub KeychainKind);

BIP84 template. Expands to wpkh(key/84'/{0,1}'/0'/{0,1}/*)

Since there are hardened derivation steps, this template requires a private derivable key (generally a xprv/tprv).

See Bip84Public for a template that can work with a xpub/tpub.

Example

use bdk_wallet::template::Bip84;

let key = bitcoin::bip32::Xpriv::from_str("tprv8ZgxMBicQKsPeZRHk4rTG6orPS2CRNFX3njhUXx5vj9qGog5ZMH4uGReDWN5kCkY3jmWEtWause41CDvBRXD1shKknAMKxT99o9qUTRVC6m")?;
let mut wallet = Wallet::create(
    Bip84(key.clone(), KeychainKind::External),
    Bip84(key, KeychainKind::Internal),
)
.network(Network::Testnet)
.create_wallet_no_persist()?;

assert_eq!(wallet.next_unused_address(KeychainKind::External).to_string(), "tb1qhl85z42h7r4su5u37rvvw0gk8j2t3n9y7zsg4n");
assert_eq!(wallet.public_descriptor(KeychainKind::External).to_string(), "wpkh([c55b303f/84'/1'/0']tpubDDc5mum24DekpNw92t6fHGp8Gr2JjF9J7i4TZBtN6Vp8xpAULG5CFaKsfugWa5imhrQQUZKXe261asP5koDHo5bs3qNTmf3U3o4v9SaB8gg/0/*)#6kfecsmr");
