About Me
Hi! I'm Alex Cipher, a blockchain security expert with 1+ years of experience in smart contract auditing and Web3 security. I've dedicated my career to helping projects build secure, reliable, and investor-ready protocols.
My expertise spans across EVM-compatible blockchains including Ethereum, Polygon, and many others. I specialize in DeFi protocols (lending, DEX, staking) and crypto gambling dApps, identifying complex vulnerabilities, architectural weaknesses, business logic flaws, and gas optimizations that protect digital assets.
Beyond auditing, I'm passionate about mentoring developers, publishing security research, and staying at the forefront of Web3 security trends. When I'm not reviewing code, you can find me contributing to the blockchain security community.
