About this Gig
Is your smart contract failing, not compiling, or are you worried about security? I find the real cause, fix it, and prove it works with tests.
What I fix:
- Compile errors, version conflicts, OpenZeppelin v4 to v5 upgrades
- Failed transactions and "execution reverted" errors
- Reentrancy, access control and other security issues
- Token bugs: tax, decimals, approvals, DEX trading problems
- Gas optimization
- Failed deployments and Etherscan / BscScan verification
- Missing Hardhat or Foundry tests
What you get:
- Fixed source code with clear comments
- A short report: what was wrong, why, and how it was fixed
- Tests that prove the fix works (Standard and Premium)
Chains: Ethereum, BNB Chain, Polygon, Base, Arbitrum and other EVM chains
Please message me before ordering with your contract (or GitHub link) and the error, so I can confirm the right package.
Note: this is a code review and bug fix service, not a formal third-party audit certificate.

FAQ
What do you need from me?
Your contract source code (files or GitHub link), the error message or transaction hash, and the network it runs on.
Can you fix a contract that is already deployed?
Deployed contracts can't be changed. I fix the code and you deploy a new version, or upgrade it if your contract is upgradeable (proxy).
Do you need my private key?
No, never. I work on the code and test on testnet. You deploy from your own wallet.
Is this a full audit?
It's a professional security review with a written report, not an audit certificate from an audit firm. For a big DeFi launch I recommend a formal audit as well.
Do you work with Foundry or Hardhat?
Both. I use whatever your project already uses.
My contract is bigger than 1,000 lines. Can you help?
Yes. Message me and I'll send a custom offer.
