Mini Apps on Telegram: Complete guide to development and integration with TON

 The rise of Telegram and TON Blockchain

 The importance of the Telegram ecosystem today

Telegram is not only one of the most popular messaging apps in the world, but it has also become a robust ecosystem for the development of technology solutions.

With more than 800 million monthly active users globally, Telegram has transcended its role as a messaging platform to become a space where communities, companies and developers interact on a constant basis.

Telegram’s native support for bots, Mini Apps and its integration with the TON (Telegram Open Network) blockchain has opened up a range of possibilities for decentralized app development, enhancing the user experience and allowing developers to access advanced technologies without having to build everything from scratch.

What are Mini Apps in Telegram?

Mini Apps are small applications or web interfaces that work within the Telegram platform, offering a seamless and interactive experience without requiring users to leave the app.

These apps allow companies, projects and developers to create custom solutions that integrate directly into Telegram, facilitating everything from shopping and booking to gaming, investing and education.

One of the main advantages of Mini Apps is that they leverage the Telegram ecosystem, with its massive user base and tools such as bots, channels and chats.

This makes them an ideal solution for any project that wants to interact directly with its audience in real time.

Brief history and evolution of Mini Apps

Mini Apps were born as an extension of Telegram bots, offering more complete and dynamic interfaces.

While bots function primarily as automated assistants, Mini Apps go a step further by enabling the creation of interactive and customizable experiences that leverage Telegram’s potential.

Since its launch, thousands of Mini Apps have been developed, spanning sectors such as e-commerce, gaming, education, investment and financial services.

These applications have proven to be a powerful tool to improve interaction with the  Telegram communities, generating new opportunities for companies and technology projects.

Technical Aspects: How to develop Mini Apps
for Telegram

Prerequisites: Tools, APIs and libraries

Developing a Mini App for Telegram requires a basic understanding of its ecosystem and the tools available.

Before you begin, make sure you have the following:

1. Telegram Bot API: It is the basis for interacting with Telegram. It allows you to send messages, manage users, handle payments and connect the Mini App.
2. Telegram Web Apps: An extension that allows you to integrate web applications directly into Telegram chats or menus. This functionality is essential for creating rich and interactive interfaces.
3. TON Blockchain: To add decentralized functions, such as cryptocurrency payments, token issuance or interaction with smart contracts.
4. Recommended languages and frameworks:
   ○ Back end: Node.js, Python, or Go to manage logic and integrations with Telegram.
   ○ Front end: React, Vue.js or lightweight frameworks that allow creating fluid interfaces.
5. Additional tools:
   ○ Web hooks to receive real-time events from Telegram.
   ○ Libraries such as telegraf.js (Node.js) to simplify interaction with the Bot API.

Use of Smart Contracts in TON for advanced functionalities

Smart contracts are self-executing pieces of code stored on blockchain. In the context of Mini Apps, they can be used for:

1. Token management: Create custom tokens that can be distributed to Mini App users. For example, a TON-based rewards program.
2. Process automation: Record transactions, perform staking or distribute profits automatically according to predefined conditions.
3. Security: Thanks to the transparency of the blockchain, users can verify the logic of the smart contract and trust its execution.

Basic example:

A smart contract in TON to distribute rewards could use a feature that verifies user activity on the Mini App and then transfers tokens automatically to their wallet.

pragma ton-solidity >= 0.44.0;
contract RewardDistributor {
mapping(address => uint) public balances;
function distributeReward(address user, uint amount) public {
require(amount > 0, “Invalid reward amount”);
tvm.accept();
balances[user] += amount;
}
function getBalance(address user) public view returns (uint) {
return balances[user];

Advantages of integrating Mini Apps and TON Blockchain

Seamless interaction with users thanks to Telegram’s familiar environment

Telegram offers a familiar and widely used environment that ensures faster adoption of Mini Apps.

By integrating directly into the platform, Mini Apps eliminate the need for users to download additional applications or sign up for external services.

   ○ TON ensures that transactions are public and verifiable, increasing
   users’ trust in the platform.
   ○ Smart contracts eliminate intermediaries and ensure the automatic
   execution of processes, such as payments or reward distribution.
2. Global payments without barriers:
   ○ With TONWallet, users can make international payments in
   seconds, without relying on banks or traditional payment processors.
   ○ This allows businesses to expand their reach into global markets with
   ease.
3. Digital property:
   ○ Users can own digital assets, such as tokens or NFTs,
   directly in their wallets, without relying on third parties for safekeeping.
