💎 One of the providers for buying cryptocurrency in Telegram's built-in Gram Wallet is Walt (ex. Wallet).
While analyzing how Onramp works, I was able to obtain the session data that Telegram creates when buying cryptocurrency with fiat. The server response lists wallet as the provider and telegram_wallet as the partner.
A separate session is created for the operation, after which Telegram opens @walt with the special parameter "isOnramp: true".
Currently, you can buy:
• Gram
• USDT on the TON network
The system also returns a list of available fiat currencies and checks supported currencies, payment methods, limits, and whether the operation is available in the user's region.
