Add the HasWallet trait and Wallet interface to model.

use Bavix\Wallet\Interfaces\Wallet;

class User extends Model implements Wallet
{
    use HasWallet;
}

Now we make transactions.

$user = User::first();
$user->balance; // int(0)

$user->deposit(10);
$user->balance; // int(10)

$user->withdraw(1);
$user->balance; // int(9)

$user->forceWithdraw(200, ['description' => 'payment of taxes']);
$user->balance; // int(-191)

Purchases

Add the CanBePaid trait and Customer interface to your User model.

use Bavix\Wallet\Traits\CanBePaid;
use Bavix\Wallet\Interfaces\Customer;

class User extends Model implements Customer
{
    use CanBePaid;
}

Add the HasWallet trait and Product interface to Item model.

use Bavix\Wallet\Traits\HasWallet;
use Bavix\Wallet\Interfaces\Product;

class Item extends Model implements Product
{
    use HasWallet;

    public function canBuy(Customer $customer, bool $force = false): bool
    {
        /**
         * If the service can be purchased once, then
         *  return !$customer->paid($this);
         */
        return true; 
    }

    public function getAmountProduct(): int
    {
        return 100;
    }

    public function getMetaProduct(): ?array
    {
        return [
            'title' => $this->title, 
            'description' => 'Purchase of Product #' . $this->id, 
            'price' => $this->getAmountProduct(),
        ];
    }
}

Proceed to purchase.

$user = User::first();
$user->balance; // int(100)

$item = Item::first();
$user->pay($item); // If you do not have enough money, throw an exception
var_dump($user->balance); // int(0)

if ($user->safePay($item)) {
  // try to buy again )
}

var_dump((bool)$user->paid($item)); // bool(true)

var_dump($user->refund($item)); // bool(true)
var_dump((bool)$user->paid($item)); // bool(false)
