Project Description:
We are seeking a highly meticulous Smart Contract Auditor or Web3 QA Specialist to perform a final, rigorous stress test and security audit of our deployed earning and withdrawal system.

This is a critical, security-focused project. You must verify the integrity of the entire end-to-end process, from real-time crypto earnings to successful, functional withdrawal to multiple major wallet types.

The system is deployed on the Ethereum Mainnet and involves a custom smart contract (a reward/yield aggregator) and a React/Ethers.js frontend (based on the UltraEarningEngine.jsx file we will provide).

Scope of Work and Core Requirements (You MUST Verify This):
Deployment Verification (Ethereum Mainnet):

Double-check that the core smart contracts and all dependencies are correctly deployed, verified (on Etherscan), and operational on the Ethereum Mainnet.

Verify the ownership structure and confirm that critical administrative functions (if any) are secured.

The primary reward token contract address to verify is: 0xE1edB9510e468C745CCAD91238b83CF63BF7c7aD.

"Real-Time Earning" Logic Audit:

Rigorously audit the smart contract logic that governs the "real-time crypto earning" to ensure it calculates rewards correctly, is gas-efficient, and has no exploits (e.g., reentrancy, integer overflow, flash loan risks).

Full Withdrawal Stress Test (Metamask & Coinbase):

Conduct a full, end-to-end stress test of the withdrawal feature. This is the most critical requirement.

Functional Verification: Confirm the withdrawal is fully functional and successfully transfers the earned crypto.

Wallet Compatibility: You must successfully process withdrawals to both a MetaMask wallet and a Coinbase Wallet (or a Coinbase account, if API integrated) to confirm multi-wallet compatibility and full functionality.

Stress Testing: Test the withdrawal process with multiple, randomly generated amounts (very small fractions, moderate amounts, and significantly large amounts) to ensure correct handling of high-precision numbers and to prevent logic errors.

Required Deliverables:
Comprehensive Security & Functional Audit Report: A written report detailing any vulnerabilities found in the smart contract code and front-end withdrawal logic, along with remediation recommendations.

Live Mainnet Proof of Concept (MANDATORY): A screen recording and corresponding Etherscan transaction links proving multiple successful withdrawals (small, random, large) to both a MetaMask and Coinbase address on the Ethereum Mainnet using real crypto.

Required Skills and Experience:
3+ Years experience in Smart Contract Auditing or rigorous Web3 QA/Security Testing.

Expert proficiency with Solidity (0.8+), Ethers.js/Web3.js, and the EVM.

Proven experience with Ethereum Mainnet deployment verification and advanced Etherscan analysis.

Familiarity with common Web3 security tools (Slither, Foundry, MythX, etc.).

Extreme attention to detail is essential for spotting logical flaws, especially in token transfer and decimal handling logic.
