RepCheck: Trust Your Chain, Build Your Name

RepCheck is an innovative DeFi reputation system that automatically monitors and rewards user activities across various DeFi protocols. Built on a custom Avail-powered rollup called RepChain, the system leverages Quicknode's Streams and Functions technologies to track and reward DeFi interactions, creating a transparent and automated reputation mechanism.

Features

• DeFi Protocol Integration:
  • Uniswap swap tracking
  • Aave lending protocol interactions (borrow, repay, supply)
  • PYUSD staking for point multipliers
• Automated Transaction Monitoring: Leverages Quicknode Streams to track registered users' DeFi activities in real-time
• Smart Point Attribution: Uses Quicknode Functions to process transactions and award points automatically
• Custom Rollup Infrastructure: Deployed on RepChain, an Avail-powered rollup for optimal scalability
• Point Multiplier System: PYUSD staking mechanism for enhanced point earnings
• On-Chain Reputation: All reputation points are stored on-chain for transparency and immutability
• Comprehensive Event Logging: Detailed event emission for all major actions

Technical Architecture

Smart Contract

The system is built on a Solidity smart contract that handles:

• User registration and management
• Point allocation and tracking
• DeFi interaction monitoring
• PYUSD staking and multiplier calculations
• Administrative controls
• Batch operations for efficiency

Integration Components

1. Quicknode Streams

   • Monitors DeFi protocol interactions in real-time
   • Tracks Uniswap and Aave transactions
   • Filters transactions for registered users
   • Triggers point attribution workflows

2. Quicknode Functions

   • Processes DeFi transaction data
   • Calculates point values based on transaction types and volumes
   • Reads of PYUSD Escrow for multipliers
   • Interacts with the smart contract to award points

Appchain integration for speed, efficiency and security
