cw_bitcoin_cash
Bitcoin Cash wallet module using the shared Electrum implementation configured for BCH mainnet. Includes CashAddr handling and BCH-specific fee/priority presets.
Features
- Derive keys via BIP‑39; maintain receive/change address chains.
- Load/save snapshots of addresses, indices, and balances.
- Electrum connectivity and UTXO management.
- Create/sign/broadcast BCH transactions; calculate size-based fees by priority.
- CashAddr compatibility for addresses; migration of legacy snapshots.
- Message signing and verification.
Getting started
Create/open via the app’s wallet service using WalletType.bitcoinCash. Ensure BCH Electrum nodes are configured.
final wallet = await BitcoinCashWallet.create(
mnemonic: '...',
password: 'secret',
walletInfo: walletInfo,
unspentCoinsInfo: unspentCoinsBox,
encryptionFileUtils: encryption,
);
Usage
Fee calculation and send:
final feeRate = wallet.feeRate(BitcoinCashTransactionPriority.medium);
final pending = await wallet.createTransaction(
outputs: [
BitcoinTransactionOutput(
address: 'bitcoincash:qq...',
amount: 10000, // satoshis
),
],
feeRate: feeRate,
);
final txHash = await pending.commit();
Additional information
- See
lib/src/for:BitcoinCashWallet,BitcoinCashWalletAddresses, and helpers inbitcoin_cash_base.dart. - Snapshot migration and CashAddr normalization are handled during open.
