Hi there I’m Paul Etim

I am a Blockchain Security Researcher, Smart Contract Developer, and Fullstack Engineer.

My work sits at the intersection of smart contract security, vulnerability research, and Web3 application development. I started from frontend and fullstack engineering, building production web applications across fintech, edtech, healthtech, and e-commerce, and have since grown deeply into blockchain security, Solidity development, and audit contest research.

• 🛡️ I research vulnerabilities in Solidity, Rust, Move, Clarity, C++, and C codebases.
• 🔍 I participate in Web3 security contests and bug bounty triaging across platforms like Code4rena and Cantina.
• ⚡ I have found High/Medium severity bugs across Web3 security platforms.
• 🛠️ I build and test smart contracts using Solidity, Foundry, Hardhat, ethers.js, WAGMI, and web3React.
• 🤖 I’m interested in AI-assisted security research, audit automation, and developer tooling for smart contract analysis.
• ✍️ I also explore technical content writing and enjoy breaking down complex blockchain concepts.

Before focusing deeply on blockchain security, I worked as a fullstack developer building scalable web applications across multiple industries.

I have worked with:

React · Next.js · Vue · Svelte · TypeScript · JavaScript
Node.js · NestJS · GraphQL · REST APIs
PostgreSQL · MongoDB
AWS S3 · CloudFront · Docker · Jenkins · GitHub

This fullstack background helps me understand not just smart contracts, but the full user-facing systems that interact with them.

I enjoy finding bugs, building products, writing short stories, and reading technical articles. Security research feels like debugging with higher stakes — and better stories.
