Development environments are used for building decentralized applications and deploying smart contracts on blockchain networks. As the Ethereum ecosystem continues to grow, the need for powerful development frameworks has become increasingly important. In this article, we will go through four popular Ethereum development environments: Hardhat, Foundry, Brownie, and Truffle. Hardhat …

Smart contracts are vulnerable to various security flaws. One of these flaws is the locked ether vulnerability, which can result in funds being trapped in a contract indefinitely. In this article, we will discuss the locked ether vulnerability and how the Olympix static analyzer can help identify it. What Makes…

In Solidity, smart contracts can interact with other smart contracts through several functions such as transfer(), send(), and call(). These functions allow a contract to call a function in another contract and receive the returned value. However, if the return value is not properly checked, it can lead to vulnerabilities. …

Integer overflows and underflows are a common source of vulnerabilities in <0.8 Solidity smart contracts. In this post, we’ll explore what integer overflows and underflows are and how vulnerabilities can be remedied. What are Integer Overflows and Underflows? In Solidity, integers are represented using a fixed number of bits. For…

Upgradable Smart Contracts and How Proxy Contracts Work Smart contracts have a unique feature of autonomous execution of code on the blockchain. However, once deployed, they become immutable and cannot be updated. Upgradable smart contracts, also known as smart contract proxies, offer a solution to this problem. What are Upgradable…
