cw_decred

Decred wallet module that bridges to the native libdcrwallet via FFI. Provides high‑level methods to create/load wallets, sync, query balances/transactions, build and broadcast transactions, and sign/verify messages.

Features

• FFI bindings to libdcrwallet with an isolate‑based request/response model.
• Initialize, create, load, close wallets; watch‑only creation.
• Start sync with optional peer list; query sync status and best block.
• Query balances, list transactions and unspents, rescan from height.
• Create signed transactions and broadcast raw transactions.
• Export wallet seed; change wallet password.
• Address management (new external address, default pubkey, address lists).
• Message signing and verification.

Getting started

Ensure the platform library is available:

• Android/Linux: libdcrwallet.so
• Apple: embedded cw_decred.framework/cw_decred

Initialize and load a wallet:

final lib = await Libwallet.spawn();
await lib.initLibdcrwallet('', 'info');
await lib.loadWallet(jsonEncode({ /* libdcrwallet config */ }));
await lib.startSync('wallet.db', '');
final status = await lib.syncStatus('wallet.db');

Usage

Create, sign, and broadcast a transaction:

final signed = await lib.createSignedTransaction('wallet.db', jsonEncode({
  // inputs/outputs and policy for libdcrwallet
}));
final txid = await lib.sendRawTransaction('wallet.db', signed);

Additional information

• See lib/api/ for the isolate wrapper (libdcrwallet.dart) and low‑level bindings.
• Errors are surfaced via the PayloadResult struct; some calls support throwOnError in higher‑level wrappers.
