Tenchat Smart Contracts

This directory contains the smart contracts for the Tenchat ecosystem.

Contracts

  • TenchatToken (ERC20): Utility token for the ecosystem.
  • TenchatIdentity: Maps user addresses to usernames and IPFS profile hashes.
  • TenchatSubscription: Handles subscription payments in ETH or TENT.
  • TenchatSignaling: Stores public keys for End-to-End Encryption (E2EE) in secret chats.
  • TenchatPrediction: A prediction market engine.
  • TenchatMiniAppRegistry: Registry for third-party mini-apps.

Prediction Market Integration

The TenchatPrediction contract is designed to drive engagement and revenue through "speculation logic".

How it fits into Tenchat:

  1. In-Chat Wagers: Users in a group chat can create a prediction market (e.g., "Will Arsenal win today?") directly from the chat interface.
  2. Mini-App Interface: A dedicated "Predictions" mini-app can list all open markets, allowing users to browse and bet on global events.
  3. Social Signals: Winning bets can generate "reputation" or "badges" stored in the TenchatIdentity contract (future upgrade), displaying a user's prediction prowess on their profile.
  4. Revenue: The platform can take a small fee from the winning pool (configurable in future versions) to fund the ecosystem.
