What Is the Difference between a Receive() and a Fallback() Function in Solidity?

In modern Solidity (0.6.x+), receive() is a special function designed exclusively to handle plain Ether transfers with no call data. It is declared with receive() external payable.

The fallback() function, declared with fallback() external payable , is a catch-all that executes when a function call is made to the contract that does not match any other function signature. If a contract receives plain Ether and has no receive() function, the fallback() function will be executed instead.
