Struct bdk::descriptor::template::Bip49[−][src]

pub struct Bip49<K: DerivableKey<Segwitv0>>(pub K, pub KeychainKind);

Expand description

BIP49 template. Expands to sh(wpkh(key/49'/0'/0'/{0,1}/*))

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

See Bip49Public for a template that can work with a xpub/tpub.

Example

use bdk::template::Bip49;

let key = bitcoin::util::bip32::ExtendedPrivKey::from_str("tprv8ZgxMBicQKsPeZRHk4rTG6orPS2CRNFX3njhUXx5vj9qGog5ZMH4uGReDWN5kCkY3jmWEtWause41CDvBRXD1shKknAMKxT99o9qUTRVC6m")?;
let wallet = Wallet::new_offline(
    Bip49(key.clone(), KeychainKind::External),
    Some(Bip49(key, KeychainKind::Internal)),
    Network::Testnet,
    MemoryDatabase::default()
)?;

assert_eq!(wallet.get_address(New)?.to_string(), "2N3K4xbVAHoiTQSwxkZjWDfKoNC27pLkYnt");
assert_eq!(wallet.public_descriptor(KeychainKind::External)?.unwrap().to_string(), "sh(wpkh([c55b303f/49\'/0\'/0\']tpubDC49r947KGK52X5rBWS4BLs5m9SRY3pYHnvRrm7HcybZ3BfdEsGFyzCMzayi1u58eT82ZeyFZwH7DD6Q83E3fM9CpfMtmnTygnLfP59jL9L/0/*))#gsmdv4xr");
