Problem Statement
We want to develop a Telegram bot that will facilitate automatic interaction with various blockchains and their decentralized applications (DApps). This bot should be capable of creating a wallet, accepting deposits, bridging tokens between Ethereum and selected blockchains (like Arbitrum, Polygon, etc.), and interacting with DApps on those chains as instructed by the user. The end goal is to enable users to participate in airdrops and other blockchain events with ease and convenience.

Acceptance Criteria
Wallet Creation: The bot should be able to create a unique wallet for each user.
Accepting Deposits: The bot should provide a deposit address and accurately track incoming deposits.
Blockchain Selection: Users should be able to select which blockchains the bot interacts with.
Token Bridging: The bot should be able to bridge tokens between Ethereum and the selected blockchain.
DApp Interaction: The bot should be capable of interacting with any DApp on the selected blockchain as per the user's instructions.
Airdrop Participation: Through the interactions mentioned above, the bot should enable users to participate in airdrops.
User Interface: The bot should provide an intuitive user interface for easy configuration and command input.
Security: All user interactions with the bot should be secure and private, with the bot adhering to best practices for cryptographic security.
Technical Details
Platform: Telegram Bot API

Programming Language: Preferably Python or JavaScript (Node.js), due to the strong support and libraries available for blockchain interaction in these languages.

Libraries and APIs: Web3.js or ethers.js (for Ethereum), relevant SDKs for other blockchains (e.g., Arbitrum, Polygon), Telegram Bot API.

Wallet Management: The bot should manage private keys securely, possibly using HD wallets. The keys should never leave the secure server environment.

Blockchain Interaction: The bot will interact with Ethereum and other blockchains using their respective APIs or SDKs.

DApp Interaction: To interact with DApps, the bot will need to create and sign transactions, broadcast them to the blockchain, and monitor the results.

Airdrop Participation: The bot should monitor for upcoming airdrops, sign up the user's wallet for participation, and confirm receipt of tokens.

Security: Consider implementing rate-limiting to prevent abuse. Private keys should be stored securely and never exposed. Consider an encryption solution for sensitive data.

Database: A database to store user interaction history, wallet addresses, and other relevant information.
