Alvara APIs

The CrossChain-BitcoinL2-Investment bot leverages several APIs and services to provide a rich user experience. Here’s a breakdown of the key integrations:

Telegram API

  • Purpose: Handles user interactions, command processing, and messaging.

  • Library Used: Telegraf, a framework for building Telegram bots.

  • Endpoints:

    • /sendMessage: Sends text messages to users.

    • /sendPhoto: Sends images to users.

    • /answerCallbackQuery: Handles inline keyboard interactions.

Blockchain Interaction (Ethers.js)

  • Purpose: Facilitates secure interactions with the Ethereum blockchain.

  • Library Used: ethers.js, a JavaScript library for Ethereum.

  • Usage:

    • JsonRpcProvider: Connects to the Ethereum network.

    • Contract Class: Interacts with BitcoinL2 smart contracts, enabling functions like contribute and withdraw.

    • Transaction Management: Sends and monitors blockchain transactions.

Backend Services (Express and Axios)

  • Express Server: Hosts the bot's webhook and handles incoming requests.

  • Axios: Used for HTTP requests, such as setting webhooks and fetching external data.

  • Endpoints:

    • /webhook: Processes incoming messages from Telegram.

    • /setWebhook: Configures the bot’s webhook URL.

Security Considerations

  • Encryption: Wallet keys and sensitive data are encrypted using crypto-js and the bot’s token.

  • Secure Sessions: User sessions are managed securely within the bot’s context to prevent unauthorized access.
