A year has passed since I left my job at CoinDCX and embarked on my journey as an entrepreneur. During this time, I have been busy building Cryptocurrency Wallet apis as a service and haven't had much time to write about my experiences in the world of web3. However, I have made it a point to occasionally participate in web3 bug bounty programs to stay up-to-date with the latest security hacks, CVEs, writeups, and attack vectors. By contributing to web3 security and immersing myself in different protocols, I have gained valuable knowledge and even earned some magic internet money. Throughout the past year, I have discovered and reported multiple vulnerabilities in various apps. All of these reported vulnerabilities have been patched. My goal in publishing these writeups is to raise awareness of common security pitfalls, share my methodology with other developers and security researchers, and create a reference material for myself and others to refer to in the future.
