Blockchain & Smart Contract Security #19 1/7 Incorrect Inheritance Order in Smart Contracts and understanding the Diamond Problem.
A thread and a blog by @SolidityScan

In past 2 months I wrote a lot about Smart Contract and Blockchain security. Here is the recap of @SolidityScan blogs. RT if you find it valuable :)
A thread 1/12
Blockchain & Smart Contract Security #11 1/9 Secure Account Existence check for Low-level Calls
A thread and a blogpost @SolidityScan Also read about "King of Ethers" contract hack.
