About this Gig
Is your Web3 project truly secure before mainnet deployment?
A single flaw can drain liquidity pools and destroy trust. As a blockchain developer, I provide institutional-grade Solidity smart contract security audits to safeguard your protocol against exploits.
My Auditing Methodology:
- Deep Manual Review: Line-by-line logic tracing to uncover complex flaws that automated scanners miss.
- Automated Analysis: Rigorous testing using industry tools like Slither, Mythril, and Foundry.
- Vulnerability Checks: Securing code against Reentrancy, Front-running (MEV), flash-loan attacks, integer truncation, and broken access controls.
- Gas Optimization: Identifying costly loops and inefficient execution patterns to save gas.
What You Receive:
- A professional, investor-ready PDF Audit Report.
- Clear severity breakdowns (Critical, High, Medium, Low, Info) with Proof of Concepts (PoCs).
- Actionable code recommendations to patch every discovered vulnerability.
- A free follow-up review to verify your fixes (Standard & Premium packages).
Important: Please message me before ordering.
Tools:

FAQ
Q: What do you need from me to get started?
I need a link to your GitHub repository or the raw .sol files, along with any existing documentation, white-papers, or a README file that explains the intended business logic of your protocol.
Does an audit guarantee my smart contract is 100% un-hackable?
No audit can provide a 100% mathematical guarantee of security. However, a rigorous audit drastically reduces risk by identifying known vulnerabilities, edge cases, and logic flaws before malicious actors find them.
Will you rewrite or fix the vulnerabilities for me?
As an auditor, my role is to find the vulnerabilities and provide exact, actionable code recommendations to patch them. It is best practice for your development team to implement the fixes, after which I will conduct a re-audit (included in Standard and Premium) to verify them.
What if my codebase is larger than 1,000 lines of code (nSLOC)?
For massive protocols, custom DEXs, or complex multi-contract systems, please send me a direct message with your repository link. I will review the scope and provide a custom delivery timeline and price.
What specific tools do you use during the audit?
I use a combination of deep manual line-by-line logic tracing and industry-standard automated frameworks, primarily Slither, Mythril, and Foundry (for fuzzing and unit testing where applicable).
Do you keep my unreleased code confidential?
Absolutely. I treat all unreleased code with strict confidentiality. I am happy to sign a Non-Disclosure Agreement (NDA) before you share your repository if your project requires it.
