The main difference between fallback() and receive() in Solidity is that fallback() is called when a contract receives Ether without any calldata, while receive() is called when a contract receives Ether with empty calldata. In other words, fallback() is called when a user sends Ether to a contract directly, while receive() is called when a user calls a function on a contract without passing any..

The receive() function in Solidity is a special function that is called automatically when a contract receives Ether without any calldata. This can happen when Ether is sent to the contract using the transfer() function or when a user sends Ether to the contract directly. The receive() function cannot have any arguments or return a value. It can only contain code that interacts with the contract..

The main difference between call() and delegatecall() in Solidity is that call() executes code in a new context, while delegatecall() executes code in the context of the caller. call() When you call a function using call(), the called function is executed in a new context, with its own stack and storage. This means that the called function does not have access to the caller's state, and any chan..

Delegatecall is a low-level Solidity opcode that allows a contract to execute code from another contract while using the state and storage of the calling contract. This can be used to implement a variety of features, such as: Upgrading contracts without losing data: Delegatecall can be used to upgrade a contract to a new version without losing any of the data stored in the contract. This is done..

The call() function in Solidity is a low-level function that can be used to call functions on other contracts or to send Ether to other addresses. It is a very powerful function, but it can also be dangerous if used incorrectly. The call() function takes two arguments: the address of the contract to call and the calldata to send to the function. The calldata is a byte array that contains the fun..

The transfer() function in Solidity is used to transfer Ether to an address. It takes two arguments: the address to transfer the Ether to and the amount of Ether to transfer. The transfer() function returns a boolean value indicating whether the transfer was successful. If the transfer was successful, the function returns true. If the transfer was unsuccessful, the function throws an exception a..
