$this of type Bavix\Wallet\Traits\CanExchange is incompatible with the type Bavix\Wallet\Interfaces\Wallet expected by parameter $object of Bavix\Wallet\Services\WalletService::getWallet().

        return DB::transaction(function () use ($from, $to, $amount) {
            $rate = app(ExchangeService::class)->rate($from, $to);

            $withdraw = $from->forceWithdraw($amount + $fee);
            $deposit = $to->deposit($amount * $rate);

$amount * $rate of type double is incompatible with the type integer expected by parameter $amount of Bavix\Wallet\Interfaces\Wallet::deposit().
