I will do a smart contract security audit and vulnerability review
Never Trust, Verify

About this Gig
Before you go to mainnet, make sure your contract can't be drained.
I'm a Web3 security researcher and Solidity developer. I review your smart contract line by line to find the vulnerabilities that lead to real losses reentrancy, access control flaws, integer issues, logic bugs, gas problems and unsafe patterns.
What you get:
- Manual, line-by-line security review of your Solidity code
- Clear report of findings, each rated by severity (Critical Low)
- Concrete recommendations and fixes for every issue
- Gas & best-practice suggestions
- A follow-up review after you apply the fixes
Honest note: no audit can guarantee a contract is 100% safe. What I do is significantly reduce your risk by catching the issues attackers look for, and give you a clear path to fix them.
Best for DeFi contracts, tokens, staking, vesting, ICOs and custom logic.
Message me before ordering with your contract or repo so I can confirm scope and pricing based on lines of code and complexity.
Token standard:
ERC-20
Programming Language:
Solidity
Blockchain platform:
Ethereum
FAQ
What kind of contracts do you audit?
Solidity contracts of all kinds — DeFi protocols, tokens, staking, vesting, ICOs, NFTs and custom logic. Send me your code and I'll confirm scope.
What does the report include?
Every finding, rated by severity (Critical to Low), with a clear explanation and a concrete recommendation or fix for each one, plus gas and best-practice notes.
Can you guarantee my contract is 100% safe?
No honest auditor can. An audit strongly reduces your risk by catching known vulnerability classes and logic issues, but security is ongoing. For high-value protocols I recommend more than one audit.
Do you also fix the issues, not just report them?
I provide clear fix recommendations for each finding. If you'd like me to implement the fixes directly, I can do that as a separate custom offer.
How do you price an audit?
Mainly by lines of code and complexity. Message me your contract or repo before ordering and I'll confirm the right package.
