Access Control Vulnerabilities in Solidity Smart Contracts
Master Smart Contract HackingBecome a smart contract hacker 😎 → https://bit.ly/become-smhWhat is SoliditySolidity Programming Language The Solidity programming language enables the development of Ethereum smart contracts. A smart contract defines the rules and conditions by which transactions and other interactions can take place on a blockchain. With Solidity, developers can write these contracts in a high-level language similar to JavaScript, which makes it easy to use and understand. On t...

DelegateCall in Solidity — With Some Code Examples - Johnny Time - Medium
DelegateCall SolidityDelegateCall is a unique feature in Solidity, which allows contract A to execute code in contract B with contract A storage, and the preserving the msg (msg.sender, msg.value, etc..). Today, we will discuss how DelegateCall works and provide some code samples.Understanding DelegateCallDelegateCall is a low-level Solidity opcode that allows a contract to execute code from another contract, but it using the state and the storage of the calling contract. The syntax for Deleg...
