The send method closely resembles transfer, but it provides a boolean return value to indicate the success or failure of the transfer. Similar to transfer, it also sends a fixed amount of gas (2300 gas) and reverts if the transfer fails. Here’s an example of using the send method:
function sendEtherUsingSend(address payable _to) public payable {
bool sent = _to.send(msg.value);
require(sent, “Failed to send Ether”); // USE Require in Send because send has no REVERT.....
}
Despite the send method providing a return value, it is no longer recommended for sending Ether due to potential re-entrancy attacks and the limited gas provided. It is advisable to use the call method instead.
