Here is the route for the /requestotp
Route::any('/requestotp', '[email protected]');

Here is the route for verify_otp when withdraw! button is clicked
Route::post('verify_otp', '[email protected]');

i have added OTP(uppercase) column to my users table Here is my crypto_transaction model
<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class CrytoWithdrawal extends Model
{
use HasFactory;
protected $table= 'cryto_withdrawals';
protected $fillable = [
'payment',
'amount',
'cryptowlletaddr',
'OTP',
'user_id'
];
}

Here is my TransactionController
\```
<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Models\USer;
use Validator;
use Exception;
use Log;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Password;
use Illuminate\Support\Facades\Mail;
use App\Mail\sendEmail;
use App\Models\crypto_tansaction;
use App\Models\cryto_payments;

class TransactionController extends Controller
{
public function requestotp(Request $request)
{

$otp = rand(1000,9999);
Log::info("otp = ".$otp);
$user = User::where('email','=',$request->email)->update(['otp' => $otp]);

if($user){
// send otp in the email
$mail_details = [
'subject' => 'Testing Application OTP',
'body' => 'Your OTP is : '. $otp
];

\Mail::to($request->email)->send(new sendEmail($mail_details));

return response(["status" => 200, "message" => "OTP sent successfully"]);
}
else{
return response(["status" => 401, 'message' => 'Invalid']);
}
}


public function verifyotp(Request $request){

$user = User::where([['email','=',$request->email],['otp','=',$request->otp]])->first()->User::where(['otp','=',$request->otp]) '=' cryto_transaction::where(['otp','=',$request->otp]);
$totalwithdrawal= CrytoWithdrawal::find(1)->sum('amount');
$totalamount= $amountpaid-$totalwithdrawal;
if($user){
$checkamount= $totalamount, '=', crypto_transaction::where(['amount', '=',$request->amount]);
if ($checkamount){
public function store(Request $request)
{
$withdraw = new crypto_transaction;
$withdraw->payment = $request->input('payment');
$withdraw->amount = $request->input('amount');
$withdraw->cryptowlletaddr = $request->input('cryptowlletaddr');
$withdraw->OTP = $request->input('OTP');
$withdraw->user_id = auth()->id();
$withdraw->save();
return redirect()->back()->with('status', 'Withdrawal Request Successfully Received');
}
}
else{
return response(["status" => 401, 'message' => 'Insufficient Amount']);
}

User::where('email','=',$request->email)->update(['otp' => null]);
$accessToken = auth()->user()->createToken('authToken')->accessToken;

return response(["status" => 200, "message" => "Success", 'user' => auth()->user(), 'access_token' => $accessToken]);
}
else{
return response(["status" => 401, 'message' => 'Invalid OPT token']);
}
}
}

Here is crypto_withdrawal table
<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('crypto_withdrawals', function (Blueprint $table) {
$table->id();
$table->string('paymethod');
$table->string('amount');
$table->string('cryptowlletaddr');
$table->string('OTP');
$table->timestamps();
});

}

/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
//
}
};

Here is my crypto_payments model
use Victorybiz\LaravelCryptoPaymentGateway\Models\CryptoPaymentModel;

$cryptoPayment = CryptoPaymentModel::find($paymentID);

$cryptoPayment = CryptoPaymentModel::where('paymentID', $paymentID);

$processedCryptoPayment = CryptoPaymentModel::where('processed', true);

$amountpaid= CryptoPaymentModel::find(1)->sum('amount');

And here is my sendEmail
<?php

namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;

class sendEmail extends Mailable
{
use Queueable, SerializesModels;

/**
* Create a new message instance.
*
* @return void
*/
public function __construct()
{
//
}

/**
* Build the message.
*
* @return $this
*/
public function build()
{
return $this->view('view.name');
}
}
