In this article, we’ll start familiarizing ourselves with the order of evaluating expressions in Solidity. Plus, you’ll learn about multiple assignments (tuple assignments). Let’s go! 💪 It’s part of our long-standing tradition to make this (and other) articles a faithful companion or a supplement to the official Solidity documentation. Order of Evaluation of Expressions Some … Read more
Salted contract creation uses cryptographic “salt” to add an additional layer of security to a smart contract. Salt is a random string added to the contract code to make it harder for an attacker to reverse engineer the code and gain access to the contract. This makes the contract more secure and helps protect the … Read more
In this article, we’ll take a closer look at how contracts are created, both directly, i.e. while being implicitly deployed on the blockchain, and indirectly, i.e. when their creation is triggered by another contract. It’s part of our long-standing tradition to make this (and other) articles a faithful companion, or a supplement to the official … Read more
