Key Features Implemented & Tested

✅ Epoch-Based Staking System

• Stake creation (individual and batch)
• NEW: endEpoch function with paybackPercent parameter
• Unlock percentage calculations based on TVL/liability ratios
• Unclaimed funds tracking and claiming

✅ Marketplace Functionality

• Listing stakes for sale by payback value
• Protocol share mechanism (50% of price/value difference)
• Cancellation fees
• Purchase mechanics
• History tracking

✅ Access Control

• Owner management (add/remove)
• Bot authorization
• Proper permission checks

✅ Admin Functions

• Parameter updates (lockup, delays, percentages)
• Fee configuration

Dependencies

• Hardhat v2.26 - Modern build system
• OpenZeppelin v5 - Latest security contracts
• Ethers v6 - Latest Ethereum library
• Chai v4 - Testing assertions

Running Tests

Contract Changes from Original

1. Removed Upgradeable Pattern: Converted from upgradeable to regular contract
2. Dynamic Owner: Constructor uses msg.sender instead of hardcoded address
3. Fixed Access Control: addBot function uses onlyOwner modifier
4. Added Validation: Zero address checks for admin functions
5. New Epoch Parameter: endEpoch now accepts paybackPercent parameter

Next Steps

1. Expand Test Coverage: Add more comprehensive marketplace and epoch scenarios
2. Mock Token Integration: Add ERC20 token interaction tests
3. Event Testing: Add comprehensive event emission verification
4. Gas Optimization: Analyze gas costs and optimize
5. Deployment Scripts: Add deployment and verification scripts

This project demonstrates the complete testing infrastructure for the CunaFinanceBsc contract with the new paybackPercent functionality working correctly.
