Struct bdk_wallet::descriptor::template::Bip49Public

pub struct Bip49Public<K: DerivableKey<Segwitv0>>(pub K, pub Fingerprint, pub KeychainKind);

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

This assumes that the key used has already been derived with m/49'/0'/0' for Mainnet or m/49'/1'/0' for Testnet.

This template requires the parent fingerprint to populate correctly the metadata of PSBTs.

See Bip49 for a template that does the full derivation, but requires private data for the key.

Example

use bdk_wallet::template::Bip49Public;

let key = bitcoin::bip32::Xpub::from_str("tpubDC49r947KGK52X5rBWS4BLs5m9SRY3pYHnvRrm7HcybZ3BfdEsGFyzCMzayi1u58eT82ZeyFZwH7DD6Q83E3fM9CpfMtmnTygnLfP59jL9L")?;
let fingerprint = bitcoin::bip32::Fingerprint::from_str("c55b303f")?;
let mut wallet = Wallet::create(
    Bip49Public(key.clone(), fingerprint, KeychainKind::External),
    Bip49Public(key, fingerprint, KeychainKind::Internal),
)
.network(Network::Testnet)
.create_wallet_no_persist()?;

assert_eq!(wallet.next_unused_address(KeychainKind::External).to_string(), "2N3K4xbVAHoiTQSwxkZjWDfKoNC27pLkYnt");
assert_eq!(wallet.public_descriptor(KeychainKind::External).to_string(), "sh(wpkh([c55b303f/49'/1'/0']tpubDC49r947KGK52X5rBWS4BLs5m9SRY3pYHnvRrm7HcybZ3BfdEsGFyzCMzayi1u58eT82ZeyFZwH7DD6Q83E3fM9CpfMtmnTygnLfP59jL9L/0/*))#3tka9g0q");
