You will get Professional Solidity smart contract security audit with full report
Project details
I'm a smart contract developer AND security researcher; most auditors can only do one. Because I write production Solidity myself, I know exactly where contracts break: reentrancy, access control flaws, integer issues, flash loan attacks, and gas waste.
Every audit you get from me includes:
• Full manual line-by-line review
• Automated analysis (Slither + Mythril)
• Proof-of-concept exploits in Foundry that prove each critical bug
• A clear, professional report with severity ratings and exact fix recommendations
• Free retest after you patch (Advanced tier)
I don't just hand you a list of warnings. I show you the vulnerable code, prove the exploit works, and give you the exact fix. My reports are clean enough to show your investors and users.
I've worked on ERC20/ERC721 contracts, DeFi protocols, and NFT ecosystems, including Cardano projects. Whether you're launching a token, a staking vault, or a full DeFi protocol, I'll make sure it's secure before it goes live not after an exploit drains it.
Let's protect your project. Send me your contract and let's talk.

About Obasanjo
Smart Contract Developer & Security Auditor | Solidity | Pentest
Lagos, Nigeria - 5:21 pm local time
Most developers write contracts. Most security researchers find bugs. I do both, which means I can ship Web3 products that are secure from day one not after an exploit drains your protocol.
What I do:
Smart contract development (ERC20, ERC721, DeFi, staking, DAOs) on Ethereum, BSC, and EVM-compatible chains
Smart contract security audits reentrancy, access control, integer overflow, flash loan attacks, and more
Full-stack Web3 dApps (frontend + Solidity + backend APIs)
Penetration testing for Web3 projects and backend systems
My stack: Solidity · Hardhat · Foundry · Python · Node.js · React · Web3.js · Ethers.js
I've worked on Cardano NFT projects (SpaceBudz, CNFT ecosystems), DeFi tools, and automation bots. I write clean, gas-optimized code and deliver detailed audit reports with proof-of-concept exploits and fixes not just a list of warnings.
If you're launching a protocol, token, or dApp and need it done right and done securely, let's talk.
Steps for completing your project
After purchasing the project, send requirements so Obasanjo can start the project.
Delivery time starts when Obasanjo receives requirements from you.
Obasanjo works on your project following the steps below.
Revisions may occur after the delivery date.
Code Review & Scope Confirmation
I review your contract, confirm the scope, and identify all files and functions to be audited
Automated & Manual Analysis
I run Slither and Mythril static analysis, then perform a line-by-line manual review against known vulnerability patterns.
