Can send some data from smart contract to an EOA by Solidity call statement?

Question

It is done by web3js sending some data from an EOA a contract by:

myContract.methods.function().send({data:...});

Can the same be done from contract to EOA by Solidity (I mean by .call())?

Answer 1

Yes you can, but it does not send anything, and the EOA address does not receive anything (because it doesn't have bytecode logic to receive)

contract Test {
    bool public success;
    bytes public data;
    function test (address target) public {
        (success, data) = address(target).call("0x1234");
    }
}

• If target is a contract, success = true if the call successful and success = false if the call reverted, depends on the logic of the target contract
• If target is a normal address (EOA), success is always true
