I will do live security reviews of Ethereum smart contracts and share my approach to auditing on a stream. The live stream is scheduled to start at 3.30 PM GMT on Sunday (22/08/2021). Link: https://www.youtube.com/watch?v=LLiJK_VeAvQ Notes Here are some brief notes that I’ll use as talking points on the stream. A detailed blog post will …
Rust is a programming language that is geared towards speed and safety. Rust has gained a lot of adoption in the past few years and developers are loving it. Although there are numerous other systems programming languages, Rust is one of the very few alternatives to C/C++ that can hold its own when it comes …
Solidity is a special language with many little quirks. A lot of things behave differently in Solidity than most other languages as Solidity is created to work on the EVM with its limited feature set. I wrote a blog post with ten tips to save gas in Solidity a few months back and it got a great …

The Truffle Suite is the most widely used development framework for Solidity development but it is not perfect. We at Polymath, deal with a large set of smart contracts. The sheer number of smart contracts cause the compilation time to go over 80 seconds on my daily driver. Lucky for us, we can make the compilation go faster. …

Smart contracts have evolved into being more than just basic contracts. Now we have whole ecosystems powered by Smart Contracts! No matter how careful we are or how well tested our code is, if we are creating a complex system, there is a good chance that we will need to update the logic to patch …
Coding in solidity is a little different than other languages as every action you do cost real gas. Here are some tips and tricks to help you keep your gas cost low. 1) Pack your variables! In ethereum, you pay gas for every storage slot you use. A slot is of 256 bits, and you …
