Example #
// Initialize keychain
const mnemonic = 'abandon broom kind...';

final keychainSecret = KeychainCoreSecret.fromMnemonicString(mnemonic);

final keychain = WalletKeychain.fromCoreSecret(
keychainSecret,
walletSize: 50,
);

// Initialize full node
final certBytes = File('CERT_PATH').readAsBytesSync();
final keyBytes = File('KEY_PATH').readAsBytesSync();

final fullNode = ChiaFullNodeInterface.fromURL(
'FULL_NODE_URL',
certBytes: Bytes(certBytes),
keyBytes: Bytes(keyBytes),
);

final wallet = ColdWallet(
fullNode: fullNode,
keychain: keychain,
);

await wallet.sendXch(
Address('RECEIVER_ADDRESS').toPuzzlehash(),
amount: 1000000000,
