Rumor Contracts

DeFi protocol for automated yield farming on Polygon using proxy accounts with shared strategy execution.

Overview

Rumor Contracts enables users to deploy individual proxy contracts that execute shared investment strategies across Aave V3 and Uniswap V3. Each user owns their proxy account while benefiting from a shared strategy executor that splits USDT investments 50/50 between Aave USDT and USDC lending pools.

Architecture

Core Contracts

• ProxyAccount.sol - User-owned contract for token management and strategy execution

  • Owner-only access control
  • Meta-transaction support (EIP-712)
  • Fee collection (0.1% default)
  • Integration with Aave V3 and Uniswap V3

• ProxyFactory.sol - Factory for deploying standardized proxy accounts

  • One proxy per user
  • Immutable protocol configuration

• StrategyExecutor.sol - Shared strategy implementation

  • Splits USDT 50/50
  • Deposits 50% to Aave USDT pool (receives aUSDT)
  • Swaps remaining 50% to USDC via Uniswap V3
  • Deposits USDC to Aave (receives aUSDC)
  • Slippage protection: 0.5%

• LendingStrategy.sol - Abstract interface for strategies

Installation

forge install

Build

forge build

Test

forge test

For mainnet fork testing:

forge test --fork-url https://polygon-rpc.com

Deploy

forge script script/Deploy.s.sol:Deploy --rpc-url <polygon_rpc_url> --private-key <private_key> --broadcast

1. Create Proxy Account

address proxy = proxyFactory.createProxy();

2. Execute Strategy

// Approve USDT to proxy
IERC20(USDT).approve(proxy, amount);

// Execute strategy
ProxyAccount(proxy).runStrategy(address(0), amount); // address(0) uses default strategy

3. Claim Yields

// Withdraws from Aave, swaps USDC to USDT, transfers to owner
ProxyAccount(proxy).claim();

Features

• Gas Efficient: Shared strategy executor reduces deployment costs
• Owner Control: Full ownership of individual proxy accounts
• Meta-transactions: Gasless operation support
• Security: ReentrancyGuard, owner-only access, slippage protection
• Multicall: Batch operations in single transaction

Fee Structure

• Strategy fee: 0.1% (10 basis points)
• Fee recipient: Configurable at deployment
• Fee deducted before strategy execution

Technical Stack

• Solidity: ^0.8.20
• Framework: Foundry
• Dependencies: OpenZeppelin Contracts, Forge Std
