Create a wallet in a single-click from your telegram mini-app.

​
Introduction

Attention Required: Telegram Bot Secret SecurityTo use automatic wallet creation for Telegram, developers must create a Telegram bot configured with a bot secret, which serves as both the control mechanism for the bot and as a symmetric key for authentication. This key technically grants the developer an ability to sign authentication data and actions with a wallet. Any compromise of the bot secret internally or externally can expose users and their accounts to significant risk. Securing this symmetric key is critical to ensuring the integrity of all Telegram login sessions in your application.
No transactional MFA must also be enabled to use this feature. Please let us know in Slack if you need it by DMing Matthew Foyle your Environment ID along with a description of your request.
Seamless Telegram Login with Telegram Web Apps improves user experience by enabling quick access directly within Telegram Messenger. Users can launch a mini app and get automatically logged in.

Telegram Authentication Check for Existing Users

This feature avoids accidental duplicate account creation by ensuring that users with existing accounts don’t create unnecessary new ones if their account is not yet linked to Telegram. The isAuthWithTelegram() function verifies whether the user is authenticated through Telegram. If the user is linked with Telegram, they are automatically logged in. If not, a splash modal prompts the user to confirm if they have an account. Based on the user’s response, they are either are prompted to log in or a new account is automatically created and logged in. This ensures app owners can maintain a single user identity, avoiding duplicate accounts.
Hook is available from SDK version 3.1.3
Full working example in our Telegram Mini App repository here
  1. Import the necessary Telegram authentication functions: 
    import { useTelegramLogin } from "@dynamic-labs/sdk-react-core";

const { telegramSignIn, isAuthWithTelegram } = useTelegramLogin();
  2. Check if the user is authenticated via Telegram: Use isAuthWithTelegram() to determine if the user is linked with Telegram. 
    const checkTelegramConnection = async () => {
  const isLinkedWithTelegram = await isAuthWithTelegram();

  if (isLinkedWithTelegram) {
    // Auto login if Telegram is connected
    await telegramSignIn();
  } else {
    // Show modal splash page
  }
};
  3. Handle the modal splash response: If the user has an account: Prompt developer’s login into the app without creating a new account. If the user doesn’t have an account: Automatically create a new account and log the user in. 
    const handleModalResponse = async (hasAccount: boolean) => {
  if (hasAccount) {
    // Prompt developer's login
    console.log("User already has an account on XYZ");
  } else {
    // Call signIn with autoCreate: true
    console.log(
      "User does not have an account on XYZ => Auto Create + Auto Login"
    );
    await telegramSignIn({ forceCreateUser: true });
  }
};

Providing the Telegram auth token to Dynamic

The Telegram Auto-Wallets feature allows you to authenticate your end user with Dynamic using a Telegram authentication token directly. There are currently two ways to provide this token to our SDK.
  1. Pass the auth token as a query parameter when the mini app is launched.
In this approach, your Telegram Bot script generates the Telegram auth token and appends it to your mini app URL. When telegramSignIn is called within your mini app, the token is grabbed from the URL query parameters and used to authenticate the user
  1. Pass the auth token directly into the telegramSignIn hook
In this approach, you directly pass the Telegram auth token into the telegramSignIn hook. This is useful if you are generating the Telegram auth token somewhere outside of Telegram such as your backend. 
await telegramSignIn({ forceCreateUser: true, authToken: 'telegram-auth-token-goes-here' });
