On Ethereum, the Ethereum Virtual Machine (EVM) is the execution environment for running smart contracts. The EVM uses a deterministic model, meaning that for a given input, the execution of a smart contract will always produce the same output.
When smart contracts are deployed or functions within them are called, the execution of these actions always requires a specific amount of gas, which is determined based on the computational needs to complete them.
The delegatecall function is a special type of message call. It is almost identical to a regular message call, except that the destination address is executed within the context of the calling contract, and the msg.sender and msg
With the rapid advancements in the field of Smart Contracts and the expanding use of Blockchain technology across various industries, the security analysis and review of these contracts have become increasingly important.
