About this Gig
A smart contract bug is not a bug. It is a withdrawal.
Once deployed you cannot patch it. Every reentrancy path, unchecked call and broken access modifier stays there permanently, readable by anyone. Attackers read contracts more carefully than most teams do.
I audit Solidity with a method, not a glance.
MY PROCESS
1. Automated sweep Slither, Mythril and fuzzing to clear the known classes fast
2. AI-assisted multi-agent review my own pipeline, where separate agents hunt reentrancy, access control, oracle manipulation and economic logic in parallel
3. Manual line-by-line review where the real findings come from, because the expensive bugs are logic bugs no scanner understands
4. Severity-ranked report Critical to Low, with the exact line, an exploit scenario and the fix
Every audit is checked against the OWASP Smart Contract Top 10.
WHY ME
25+ years in software, specialised in smart contract security and DeFi. I built the multi-agent auditing pipeline used here and have published technical work on AI-assisted Solidity auditing.

FAQ
Can you guarantee my contract is unhackable after this?
No, and be careful with anyone who says otherwise. No audit can prove the absence of every bug. What I do is find the known vulnerability classes and the logic flaws a careful attacker would look for, then document exactly what I checked and what I could not cover.
What is the difference between this and a $30 audit?
A cheap audit is usually a Slither scan pasted into a document. Scanners catch maybe half of what matters and miss almost every business-logic flaw, which is where the large exploits actually come from. Manual review is the work you are paying for.
Will my contract code stay confidential?
Yes. I never share, publish or reuse client code and I am happy to sign an NDA through Fiverr first. If your contract is already deployed and verified on a block explorer it is public anyway, but unpublished code stays strictly private.
Which chains and standards do you cover?
Any EVM chain: Ethereum, BNB Chain, Polygon, Arbitrum, Base, Optimism and others. Standards include ERC-20, ERC-721, ERC-1155 and ERC-4626, plus custom DeFi logic staking, vaults, AMMs, lending and vesting.
Do you fix the problems or only report them?
The Premium package includes me writing the fixes and then re-auditing the patched contracts. Basic and Standard are report-only, but every finding includes a concrete recommended fix your developer can implement directly.
How do I know the report is worth showing investors?
It is a formal PDF with scope, methodology, severity classification, per-finding exploit scenarios and remediation status, the structure a professional audit firm uses. Message me and I will send a sample report before you order.
