cw_bitcoin
Bitcoin-family Electrum wallet implementation used by Cake Wallet (BTC, LTC and derivatives).
Features
- Electrum client and wallet with address/UTXO management and snapshots.
- Derivation via BIP‑39; receive/change chains with per-coin configs.
- Create/sign/broadcast transactions; PSBT helpers and payjoin support.
- Transaction history, priorities, and size-based fee calculations.
- Hardware wallet support for BTC/LTC.
Getting started
Use the module via app services (see bitcoin_wallet_service.dart, litecoin_wallet_service.dart). Ensure Electrum nodes are configured for the target coin.
final wallet = await BitcoinWallet.create(
mnemonic: '...',
password: 'secret',
walletInfo: walletInfo,
unspentCoinsInfo: unspentCoinsBox,
encryptionFileUtils: encryption,
);
Usage
Send BTC with medium priority:
final feeRate = wallet.feeRate(BitcoinTransactionPriority.medium);
final pending = await wallet.createTransaction(
outputs: [BitcoinTransactionOutput(address: 'bc1...', amount: 50000)],
feeRate: feeRate,
);
final txHash = await pending.commit();
See lib/ for wallet/services, PSBT, and payjoin utilities.
