Solidity smart contract to send hard coded ether amount to hard coded wallet address in Remix IDE with out using the Remix input value field

Question

I am trying to send ether from one wallet to another. The receivers wallet and the ether amount is hard coded in contract. This is how the contract looks. I am using the Remix IDE with injected provider - Meta Mask as the environment

pragma solidity ^0.8.15;
// SPDX-License-Identifier: MIT


contract sendeth{

    
    address payable public target = payable(xxxxwalletAddress);
    uint public etherAmount = 1 ether;


    function sendEth() public payable {
        payable(target).transfer(etherAmount);
    }

}

It gives me an error:

Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending? Returned error: {"jsonrpc":"2.0","error":"execution reverted","id":2658715818644854}

However if I enter 1 ether in the Remix IDE "Value" field it allows me to send the ether. I do not want to do that as the ether value is hard coded in the contract. Am I missing something here?

I also tried using the msg.value but that does not work either:

function sendEther() public payable {
        require(msg.value == etherAmount, "Incorrect Ether amount sent");
        payable(target).transfer(msg.value);      
       
        
    }

Answer 1

What you're asking for is simply impossible, the amount of ether sent by a transaction is decided by the sender, you can't pull ether from a wallet with a smart contract. You can require that the value sent be equal to a specific amount though, like in your second example.
