"Out of gas".. what a lovely Solidity error! This really use to make me mad when I started with Solidity smart contracts! In this video, I am going to show you how to simply solve this error and more importantly how you can find out how much gas is needed…

Debugging smart contracts - New video course on EatTheBlocks Pro. Teach how to console.log in Solidity, how to use Solidity debugger, different kind of runtime errors... I never found any other resources that comes close to this for debugging smart contracts Counterfactual development update - new framework for developing Dapps…

"out of gas", "revert", "invalid opcode", what are all these weird error names in Solidity? In this video I will give you a full list of the errors in Solidity, and I will explain them to you, so that you can easily understand whats going on when you see them.

To debug syntax errors, you can rely on Solidity syntax highlighting. Fortunately for us, Remix has syntax highlighting activated by default, so we are good about this. In this video, I will teach you: How to fix the usual Solidity syntax errors? How to setup syntax highlighting in other code…

A lot of people are confused about debugging in general and don't know the difference between a syntax error and a logic error. It's important to be understand the difference, so that you become good a debugging Solidity smart contracts. In this video, I am going to explain you simply…

When I started to debug Solidity smart contracts, I was really confused by the fact that although there was a return statement in Solidity, I could not always read returned values when triggering functions from outside the smart contract. I was confused because I didn't know that Ethereum has 2…

https://youtu.be/qCMbqqU0cYY Smart contract security - Most smart contract developers write insecure smart contracts because they dont know much about security. Want to do better than that? Follow my new series on smart contract security on EatTheBlocks Pro. Learn about Overflow, Re-entrancy attack, and more and how to fix these vulnerabilities. Interview…

https://youtu.be/YYZN96g1C7g I have interviewed Raman, the founder of cryptojobslist.com. CryptoJobsList is the first job board for crypto / Blockchain jobs. In this 28 mins interview Raman tells us how he came to create his Blockchain job board, and also give us very valuable tips for finding a crypto job, including…

Previously, we have implemented the main functionality of our split payment smart contract in Solidity. In this video tutorial, we are going to finish smart contract by adding access control. We will use Solidity require() statement for this.

In this video, we will start a smart contract to do split payments. Split payments allow to split an Ether payment into several addresses, with different amounts (i.e recipient addresses can receive different amounts). It can be especially useful for companies who want to pay employees or freelancers in Ether.…
