README

Laravel Bitcoin Module is a Laravel package for work with cryptocurrency Bitcoin. You can create descriptor wallets, generate addresses, track current balances, collect transaction history, organize payment acceptance on your website, and automate outgoing transfers.

You can contact me for help in integrating payment acceptance into your project.

Examples

Create Descriptor Wallet:

$name = 'my-wallet';
$password = 'password for encrypt wallet files';
$title = 'My First Wallet';

$node = Bitcoin::createNode('localhost', 'LocalHost', '127.0.0.1');
$wallet = Bitcoin::createWallet($node, $name, $password, $title);

Import Descriptor Wallet using descriptors:

$name = 'my-wallet';
$password = 'password for encrypt wallet files';
$descriptions = json_decode('DESCRIPTORS JSON', true);
$title = 'My First Wallet';

$node = Bitcoin::createNode('localhost', 'LocalHost', '127.0.0.1');
$wallet = Bitcoin::importWallet($node, $name, $descriptions, $password, $title);

Create address:

$wallet = BitcoinWallet::firstOrFail();
$title = 'My address title';

$address = Bitcoin::createAddress($wallet, AddressType::BECH32, $title);

Validate address:

$address = '....';

$node = BitcoinNode::firstOrFail();
$addressType = Bitcoin::validateAddress($node, $address);
if( $addressType === null ) {
    die('Address is not valid!');
} 

var_dump($addressType); // Enum value of AddressType

Send all BTC from wallet:

$wallet = BitcoinWallet::firstOrFail();
$address = 'to_address';

$txid = Bitcoin::sendAll($wallet, $address);

echo 'TXID: '.$txid;

Send BTC from wallet:

$wallet = BitcoinWallet::firstOrFail();
$address = 'to_address';
$amount = 0.001;

$txid = Bitcoin::send($wallet, $address, $amount);

echo 'TXID: '.$txid;

class EmptyWebhookHandler implements WebhookHandlerInterface
{
    public function handle(BitcoinWallet $wallet, BitcoinAddress $address, BitcoinDeposit $transaction): void
    {
        Log::error('Bitcoin Wallet '.$wallet->name.' new transaction '.$transaction->txid.' for address '.$address->address);
    }
}
