### 💻 Smart Contract Code
```solidity
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
contract DonationPool {
address public owner;
// Set the deployer as the owner (first donor)
function setOwner() internal {
if (owner == address(0)) {
owner = msg.sender;
}
}
// Receive donations
receive() external payable {
setOwner();
}
// Withdraw all funds (only by owner)
function withdraw() external {
require(msg.sender == owner, "Only owner can withdraw");
payable(owner).transfer(address(this).balance);
}
// View current contract balance
function getBalance() external view returns (uint256) {
return address(this).balance;
}
