| 1 | ## cw_dogecoin |
| 2 | |
| 3 | Dogecoin wallet module using the shared Bitcoin Electrum implementation (`cw_bitcoin`) configured for Dogecoin mainnet. |
| 4 | |
| 5 | ### Features |
| 6 | |
| 7 | - Derive keys via BIP‑39; Dogecoin HD paths using `bitcoin_base`. |
| 8 | - Connect to Electrum nodes; maintain address sets and UTXOs. |
| 9 | - Create/sign/broadcast DOGE transactions with configurable fee rate. |
| 10 | - Address book and index management (receive/change, auto-generate settings). |
| 11 | - Message signing and verification. |
| 12 | |
| 13 | ### Getting started |
| 14 | |
| 15 | Create/open via `DogecoinWalletService` in the app using `WalletType.dogecoin`. Ensure Electrum nodes are configured for Dogecoin. |
| 16 | |
| 17 | ```dart |
| 18 | final wallet = await DogeCoinWallet.create( |
| 19 | mnemonic: '...', |
| 20 | password: 'secret', |
| 21 | walletInfo: walletInfo, |
| 22 | unspentCoinsInfo: unspentCoinsBox, |
| 23 | encryptionFileUtils: encryption, |
| 24 | ); |
| 25 | ``` |
| 26 | |
| 27 | ### Usage |
| 28 | |
| 29 | Estimate fee and send: |
| 30 | |
| 31 | ```dart |
| 32 | final feeRate = wallet.feeRate(BitcoinCashTransactionPriority.medium); // example priority mapping |
| 33 | final pending = await wallet.createTransaction( |
| 34 | outputs: [ |
| 35 | BitcoinTransactionOutput( |
| 36 | address: 'D...', |
| 37 | amount: 1 * 100000000, // 1 DOGE in koinu |
| 38 | ), |
| 39 | ], |
| 40 | feeRate: feeRate, |
| 41 | ); |
| 42 | final txHash = await pending.commit(); |
| 43 | ``` |
| 44 | |
| 45 | ### Additional information |
| 46 | |
| 47 | - See `lib/src/` for classes: `DogeCoinWallet`, `DogeCoinWalletAddresses`. |
| 48 | - Relies on core Electrum features in `cw_bitcoin` for UTXO selection and persistence. |
