Hmm... i think i will contribute a telegram mini app template with in-dapp-wallet to help you. But you can also just use walletconnect.

i think the wallet handling needs improvement tho. trusting the DB storage while you own the decryption key. yes, other telegram bots do the same too but it's not good to do that.

Update: Using google authenticate to generate wallet for bot (not mini app)
Description
1 How It Works
Generate Wallet:

• User sends /start to the bot.
• Bot generates a QR code for Google Authenticator setup.
• User scans the QR code and inputs the 6-digit code.
• Bot generates a wallet, encrypts the private key, and stores it locally.
• Bot displays the wallet address.

Sign Transactions:

• User sends /sign to the bot.
• Bot prompts for the Google Authenticator code.
• User inputs the code, and the bot decrypts the private key.
• Bot signs and broadcasts the transaction, then displays the transaction hash.

2. Tech Stack

• Telegram Bot Framework: grammy (Node.js/TypeScript).
• Blockchain Interaction: ethers.js for wallet generation and transaction signing.
• Encryption: Node.js crypto module (AES-256-CBC).
• Google Authenticator Integration: speakeasy for TOTP (Time-Based One-Time Password) generation and verification.
• QR Code Generation: qrcode library.
• Client-Side Storage: Session-based storage (e.g., ctx.session in grammy).
