The number of smart contract applications deployed each day in the Ethereum Blockchain is increasing every day. Fascinated by the security aspect of the newly proposed Blockchain technology. More people are trying to deploy new smart contracts in the mainnet and most of them start holding millions of dollars in ...
The only things that truly do not change in a smart contract even with proxies concepts are state variables. However, not carefully using them in a smart contract could lead to some serious vulnerabilities. One of those vulnerabilities is called state variables shadowing. Therefore, what is smart contract shadowing state ...
Smart contract attacks usually exploit a vulnerability in a smart contract source code which leads to some serious financial losses. Therefore, ensuring that the smart contract is clean from any possible vulnerability before deploying it in the Mainnet is a must. So, how much does a smart contract audit cost? ...
Making an audit against a smart contract is a great thing. However, finding vulnerabilities without fixing them is useless. Unfortunately, smart contracts are immutable by design, which means that once the smart contract is deployed, it cannot be changed. So how to fix a smart contract? To fix a vulnerable ...
To be able to perform the different tasks and execute the operations in its source code, smart contracts require a certain level of gas. This gas is paid by the user that tries to execute the smart contract using a transaction. However, when the user does not send enough gas ...
The transaction life cycle in most Blockchain technologies is mainly controlled by miners, even the order of the transactions. Therefore, when two users execute two different transactions at the same or closer time then only their gas fees will judge who will be executed first. This concept creates a vulnerability ...
In the intricate landscape of cybersecurity, understanding the concept of malware artifacts is paramount for safeguarding digital environments.
