Telegram Bridge Bot

How the Nexium Telegram Bridge Bot Works

The Nexium Telegram Bridge Bot acts as a user-friendly interface for initiating and managing cross-chain bridge transactions directly from within Telegram. It combines Web3 wallet integration, real-time routing, backend automation, and blockchain execution — all within a conversational bot flow.

1. User Interaction Layer (Telegram Bot Interface) • Built using the Telegram Bot API, the bot provides a rich chat-based UI with buttons, inline menus, and prompts. • Users start by typing /start and selecting “Bridge Assets.” • The bot guides the user step-by-step:

   1. Connect Wallet (via WalletConnect or signing a message)

   2. Choose Source Chain

   3. Choose Destination Chain

   4. Select Token & Amount

   5. Confirm Transaction

2. Wallet Connection & Authentication • The bot initiates a WalletConnect QR code or link. • The user scans it with a wallet like MetaMask, Trust Wallet, or Rabby. • The bot verifies wallet ownership by asking the user to sign a message (not a transaction). • Wallet connection is stored temporarily (session-based) in the backend with a user-specific token tied to Telegram ID.

3. Backend API & Smart Routing System

Once the user confirms a bridging request: • The bot sends the transaction details to the Nexium backend API, which handles: • Balance verification • Liquidity availability • Route optimization (best fee/time path) • Transaction preparation • The Smart Routing Engine selects the most efficient path using: • Native liquidity pools • Partner bridge protocols • Nexium’s own bridge contracts

1. Transaction Signing & Execution • The backend sends a transaction request to the user’s connected wallet. • The user signs and submits the transaction from their wallet app. • Once signed, the Nexium system: • Executes the lock or burn operation on the source chain • Waits for block confirmations • Triggers the mint or release on the destination chain

2. Live Transaction Updates in Telegram • Users receive real-time messages in Telegram: • “Transaction sent to source chain” • “Waiting for confirmation” • “Minting on destination chain” • “Bridge complete – view on Nexium Scan” • Messages include: • Transaction hash • Explorer links • Time taken • Final delivered amount

3. Error Handling & Fallbacks • The bot handles common issues like: • Invalid token selection • Insufficient gas • Transaction reverts or timeouts • In case of failure: • Users receive a prompt to retry or contact support • The backend automatically logs the failure and retries after short intervals

4. Security Measures • End-to-end encryption via Telegram + wallet signature verification • No private keys stored; all signing happens in the user’s wallet • Rate limiting, session timeouts, and anti-bot detection • Whitelisted token and chain list to reduce attack surface • Optional 2FA prompt before large transfers (future release)

5. Additional Features • Bridge History: Users can type /history to see past bridge transactions. • Multilingual Support: Language detection based on Telegram settings. • Notifications: Enable alerts for bridge completion or wallet activity. • Integration with Nexium Scan: View cross-chain bridge analytics directly from bot links.
