Hello! I will completely take the design and logic from your current app and rebuild everything from scratch. I will integrate the payment with stars, I have experience with TG projects, so everything will work perfectly. Since there are actually only 3-4 unique screens, the work won't take much time — I will do it quickly and thoroughly.

Good afternoon.

I can develop a Telegram Web App / Mini App and integrate payment through Telegram Stars.

For the task, I see the following scope:
- restore the application structure and main scenarios;
- create 3–4 unique pages, and make the other pages based on the same template with text replacement;
- connect the Telegram Mini App;
- implement payment through Stars;
… - process successful payments and grant access/results;
- test the functionality within Telegram.

Before starting, I need to clarify whether there is the source code of the old application, a mockup/Figma, or just screenshots, as well as whether there is an already prepared bot and server.

Estimated cost: 15,000 UAH.
I can confirm the exact timeline and final price after reviewing the design and description of the mechanics.

I understood the task — to recreate the Telegram Mini App from scratch based on a live application + connect payment through Telegram Stars.
What I will do:
— Reproduce the design and mechanics based on the live application
— Develop all pages (10 pages where the text changes — I will make them as components)
— Connect payment through Telegram Stars
— Telegram bot for processing payments
Stack: React + TypeScript + Tailwind
Send me the link to the live application — I will take a closer look and give a more accurate estimate!

Hello! I am Vladimir, the founder of the engineering agency Vaysed. Your task of restoring the functionality of the Web App and integrating a new payment system perfectly fits our technical stack. Since direct access to the source code is lost, we will conduct a proper reverse engineering of your application: we will carefully extract the current layout, styles, and animations, after which we will transfer these unique screens to a modern fast framework, React. We will write all internal logic, page transitions, and the database from scratch in Node.js or Python, so you will receive a completely new, secure, and controllable backend architecture. We will implement payment integration through the official API of the messenger, setting up the generation of invoices in the internal currency Telegram Stars and ensuring error-free processing of webhooks for instant crediting of purchases to users. Our team regularly works with complex mechanics within Telegram Mini Apps and the restoration of lost data streams. We have successfully refined the logic for working with internal balances and transactions in our crypto projects Droplet Casino and WorkersTon, perfectly configured strict routing of user interfaces in the large-scale ecosystem RESTART 2026, and ensured the reliable operation of background processes in the architecture of the autonomous system Lumos. You can evaluate our systems engineering approach in detail and familiarize yourself with the implemented infrastructure solutions on the official agency website https://vaysed.me/. Message me privately, send a link to your current application for an accurate assessment of the logic of the mechanics that need to be recreated, and we will promptly start development.

I can help restore and rebuild the web application: preserve the current design, logic, and mechanics, as well as integrate payment through Telegram Stars. If access to the source code is lost, we can extract the structure and interface from the already working version and rebuild the project with a proper architecture and access.

Good day.

I have experience in restoring and transferring web app / mini app projects without source code:
— restoring UI/UX and logic;
— reassembling mechanics;
— copying page structure;
— integrating Telegram Stars / payments;
— adapting for Telegram Web App;
— restoring frontend + backend logic;
… — transferring design while maintaining the current visual.

Judging by the description, the task is quite feasible:
— we will take the design and page structure;
— we will restore the main mechanics;
— we will integrate payment for Stars;
— we will optimize and prepare the project for further support.

We work carefully and as close to the original as possible.

Good day. I am an individual developer with over 4 years of experience in full-stack development, front-end reverse engineering, and creating Telegram Mini Apps on Node.js/React. I offer my services to restore your application. I guarantee direct communication without intermediaries and full legal transparency (I work through a sole proprietorship). I will independently download the structure and design of your web app, optimize 10 pages into 3–4 flexible templates with dynamic text, recreate all interaction mechanics, and write a new backend. I will also integrate native payment for Telegram Stars through server-side verification of successful_payment, set up session storage, and deploy the project on the server turn-key. My approach is presented in the portfolio: 3magency.co, https://vilors.studio/.

Hello. Our small team has been engaged in development, cloning, optimization, and Web3/Telegram integrations for commercial projects for over 4 years. We will take your blocked or lost web application, fully replicate its visual part and animations, transfer the interface logic to clean code (React/HTML/JS), and set up dynamic content replacement for similar pages. We will develop a Telegram bot, link it to the Web App, and implement an internal purchase system using Telegram Stars, logging all successful transactions. You can check the quality of our code and the level of project implementation at the portfolio links: freshagro.com.ua, farfieworldwide.com, rivnekolo.com.

Good day. My colleague and I have been specializing in the development of Telegram Mini Apps, bug fixing, and recovering lost web resources through frontend parsing for over 4 years. We will carefully gather all the mechanics and design of your old app, structure the code for 10 pages based on several dynamic screens to eliminate code duplication, and completely rewrite the server logic of the application. On the backend, we will set up webhook processing for receiving payments in Telegram Stars (pre_checkout_query / successful_payment), which will allow users to purchase services within the Mini App with one click.

Good day!

I developed a Telegram Mini App from scratch — I am familiar with the stack and mechanics. The task is clear: to access the live application, recreate the design and functionality, and integrate Telegram Stars payment.

Please clarify — is there access to the application for viewing, or only screenshots? I will provide more precise information on timelines and costs after I understand the scope.

Hello! Could you clarify which technology stack is used in the web application so that I understand how to restore access to the design and mechanics?

I will discuss the deadlines and budget more precisely in personal correspondence.

Here’s how I will execute this project:
1. I will restore access to the application or extract the design and mechanics through code analysis and network requests.
2. I will document all pages (3-4 unique templates) and describe the logic for changing the text for the rest.
3. I will set up a payment gateway for linking payments for stars and test its functionality.

… Thank you for considering my proposal. I look forward to the opportunity to work with you!

Hello, Vlad!

I can restore and bring your Mini App to a working state and connect payment with stars.

I work in stages: first, we raise and fix the current version, then we bring it to stable operation and connect payments.

Approximately 10 days, with a cost of $600–800.

I will provide the exact figure after a quick review of the current state of the application (it greatly depends on what exactly is still available).

Show original

I see the situation: the application is live, but access has been lost. We need to reverse-engineer the design and mechanics based on those 10 pages, then build a Web App on React and integrate payment via Telegram Stars API.

I did a similar case a year ago - I restored a mini-application for food delivery from screenshots and the Wayback Machine cache. It looked 1:1, and the payment via stars was working in three days.

Question: do you have any screenshots or screen recordings of the old application? Or just memories of its appearance? This greatly affects the timelines and accuracy of the result.

Good day!
I will do it. Essentially, the task is to reproduce the existing application for the frontend + integrate payment for stars.
How I will do it:

Parsing the current application — I will extract the design, fonts, colors, icons, and page structure. If the site is still available, I will make a pixel-perfect copy.
Layout — 3-4 unique templates + dynamic content for the other pages. Responsive, fast loading.
Mechanics — I will reproduce all the logic as it is now.
Payment for stars — I will connect Telegram Stars through the Bot Payments API.

… What I need from you:
Link to the current app (or screenshots if it no longer works)
Description of the mechanics that are currently in place
Bot token for connecting payment

Is the application still available for viewing or are there only screenshots left?

Hello. My partner (designer + full-stack) and I have over 4 years of experience in web development, reverse engineering, and Telegram integrations, and we are ready to promptly restore your application. We will fully download the current frontend of the web app, extract styles, media files, and interface structure, and break it down into 3–4 basic templates where the text will change dynamically. We will write a new backend in Node.js and integrate official payments through Telegram Stars using Telegram Bot API methods with payment validation on the server. Our approach to architecture and working with interfaces is reflected in our portfolio: hyperfi.tech, espressolab.com.ua, hudi.com.ua.

Good afternoon, I am ready to take on the project, I have experience, there are projects with web apps in my profile.

We already have a nearly ready database for the Telegram mini app, which can be quickly adapted to your screens, mechanics, and payment with stars. ))

In terms of timelines, I would estimate 10-14 days for careful restoration of the interface, logic, and connection of Telegram Stars without attempting to bypass access or extract closed code.

The cost is 45,000 UAH for the first working release.

It looks like a task not just to layout 10 screens, but to rebuild the mini app so that it works properly in Telegram, processes payments, stores necessary states, and does not break when text changes.

- We will restore the design and behavior based on the available version.
… - We will build the structure of pages and states.
- We will connect Telegram Stars payment.
- We will add a basic server part if needed for payment verification and data storage.
- We will prepare the launch via the bot.

Important questions:
- Do you have a link to the current web app or access only through the Telegram bot?
- After payment with stars, what exactly should the user receive - access, content, balance, goods, or another mechanism?

Similar examples based on experience:
https://business.ingello.com/vorfahr - close in product logic, automation, and integrations.
https://business.ingello.com/carveli - similar in terms of user interface, orders, and commercial logic.
