Biography

Introduction

I have a background in System Hacking and Reversing. In 2022, I ventured into Web3 security, and over the past three years, I have actively participated in many audit competitions as well as conducted private audits. While my main area of interest lies in Solidity security (recently Uniswap V4 hooks), I have recently been analyzing appchain codes written in Rust and Go.
