Audit-365 is a challenge for me where I will be posting educational content related to Smart contract auditing and web3 security throughout the 365 days of the year starting from 1st January, 2023 to 31st December, 2023. It will be full of actual content without any fillers.
Unfortunately, I had to discontinue the challenge due to health issues and other priorities. I successfully continued for around 60 days, but had to stop due to other commitments at that point in time. I hope to return soon with even more awesome ideas.
