Game Trade

Hello!

I have reviewed your project - GameTrade. I understand the task: to check the security of the marketplace, find possible vulnerabilities, and correctly configure the payment system.

I can help with the following tasks:
• backend audit and search for potential vulnerabilities (authorization, forms, API, uploads, etc.)
• checking protection against common attacks (XSS, SQL injection, CSRF, bypassing authorization)
• analyzing the logic of the marketplace and operations with balance / transactions
• configuring and verifying the correct operation of the payment system
… • recommendations for improving the security and stability of the project.

After the initial analysis, I will be able to compile a list of identified issues and propose solutions.

I am ready to review the code, project architecture, and discuss the details of collaboration.

I will check the backend for vulnerabilities: injections, XSS, CSRF, authentication issues, and API. I will set up the payment system, test the entire flow from order to payment confirmation. One question: which payment system is currently in place, or do we need to select one from scratch?

Hello

We worked on the Game Trade project — a turnkey marketplace (frontend + backend, payments, order logic)

We have experience in auditing and refining the backend:
— finding vulnerabilities and "holes"
— fixing logic
— configuring and stabilizing payment systems
— checking callback / webhook
…
We can take a look at your project, find issues, and properly set up the payment system.

Good day
My name is Dmitry, from King Kong Lab. I have reviewed your website — it is a marketplace for digital goods with a secure transaction system (escrow), where security and proper payment processing are critically important.
We can help comprehensively: not just "take a look," but actually find vulnerabilities and bring the system to a stable state.
What we will do:
- conduct a security audit (authorization, transaction logic, possible vulnerabilities)
- check the backend and business logic (logic holes, bypasses, errors)
- set up and test the payment system (correct payment processing, statuses, protection against duplicates and errors)
- check integrations and notifications
- optimize operational stability
… We work until the result — so that the site operates safely and without payment issues.
We have experience working with marketplaces, payment systems, and complex logic.
I am ready to get involved, review the project, and propose a specific plan for corrections.

Hello! I have analyzed your marketplace GameTrade. The site is built on Next.js and Node.js, which is a great foundation for scalability and security. I have extensive experience in developing backend logic and integrating payment systems.

My work plan for the project:

Security Audit: I will conduct a complete review of your API endpoints and authorization logic for vulnerabilities (SQLi, XSS, access logic).
Payment System: I will set up or update the payment system with a focus on automating Escrow processes. I have experience working with Stripe and other international gateways.
Compliance: I will check the correctness of transaction processing and the protection of user data.
I am ready to start the audit today and provide a detailed report on the identified vulnerabilities. I look forward to your feedback to discuss the details!

Hello! I am ready to look at the backend, check the website for vulnerabilities, and properly set up the payment system. The exact price depends on the website engine, the complexity of the marketplace, and the chosen payment system. I can start right now.

Good day, Nikita.

My name is Denis, I specialize exclusively in backend development. I know how to properly fix vulnerabilities, how to correct bugs, and how to quickly and effectively understand someone else's code. I do my work with quality and integrity. Clearly on time.

I have a couple of questions:
1) You mention vulnerabilities, so you have had such experience? What exactly happened?
2) What is the backend written in, as I see the frontend is on Next?
3) Which payment platform needs to be integrated?

… Let's discuss everything in detail, okay? 🙂

Best regards, Denis

Hello. I can connect.

I will look at the backend, find weak points in logic and security, and properly bring the payment system to a working state so that everything runs smoothly and without surprises. If the site is already live — that's even better, we can quickly go through the real bottlenecks and not guess in theory.
