Struct bdk::descriptor::template::Bip49Public[][src]

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

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'.

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::template::Bip49Public;

let key = bitcoin::util::bip32::ExtendedPubKey::from_str("tpubDC49r947KGK52X5rBWS4BLs5m9SRY3pYHnvRrm7HcybZ3BfdEsGFyzCMzayi1u58eT82ZeyFZwH7DD6Q83E3fM9CpfMtmnTygnLfP59jL9L")?;
let fingerprint = bitcoin::util::bip32::Fingerprint::from_str("c55b303f")?;
let wallet = Wallet::new_offline(
    Bip49Public(key.clone(), fingerprint, KeychainKind::External),
    Some(Bip49Public(key, fingerprint, 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");
