Hi there, I'm Shivansh Nigam 👋

I am a Smart Contract Security Researcher & Developer with 1.5+ years of experience specializing in auditing and securing decentralized applications. My work focuses on identifying vulnerabilities, optimizing gas usage, and ensuring robust security in blockchain protocols. Alongside my security expertise, I am proficient in developing smart contracts and integrating them into full-stack systems, with hands-on experience in Solidity, Ethers.js, React, Node.js, and frameworks like Foundry and Hardhat. Currently in the final year of my B.Tech in Information Technology, I combine research-driven security insights with strong development skills to deliver scalable, efficient, and secure Web3 solutions.
