Docker images come real handy when you don’t need to keep an environment running. You can just pull the docker image and have the environment ready for use. This is specially useful in continuous integration. Doesn’t matter if you use Travis, CircleCI or anything else, you can always reliably use a docker image and get …

Solidity 0.5.X is here with a lot of features and breaking changes. Making all the changes to your solidity code manually, especially adding the explicitness requirements can be really cumbersome (and boring) for large projects. This is why I decided to make a codemod for Solidity that does most of the work for you. It’s …

Syncing an Ethereum full node has become painfully slow as the size of a full node folder has increased to over 130 GB and is continually increasing. Optimizing your configuration can save you hours or even days of sync times. I had to sync a few nodes a couple of weeks back, so I started tuning …

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 …
Blockchain offers an innovative solution for introducing trust in a trustless environment. Blockchains and the features they bring have innumerable applications, but most of them cannot be implemented in the current generation of blockchains due to the scalability issues. To compare with real numbers, VISA processes about 2000 transactions per second while ethereum can only …
Debugging solidity smart contracts is a pain and takes a lot of time. I made a small user script which decodes the calldata to function names from the Etherscan trace for Kovan testnet. It comes handy when you need to debug some transactions real quick. You’ll get to know which function was the culprit, and …
