**สำหรับใครที่ทำ Base Camp มาถึงข้อ 11 แล้วให้ใช้ code ดังต่อไปนี้เพื่อผ่านเควสนะครับcopy ไปแปะได้เลย อย่าลืม compiler ก่อน Deploy นะครับ**

    pragma solidity ^0.8.0;
    
    contract UnburnableToken {
        mapping(address => uint256) public balances;
        uint256 public totalSupply;
        uint256 public totalClaimed;
    
        error TokensClaimed();
        error AllTokensClaimed();
        error UnsafeTransfer(address addr);
    
        constructor() {
            totalSupply = 100000000;
        }
    
        function claim() public {
            if (totalClaimed >= totalSupply) {
                revert AllTokensClaimed();
            }
    
            if (balances[msg.sender] > 0) {
                revert TokensClaimed();
            }
    
            balances[msg.sender] = 1000;
            totalClaimed += 1000;
        }
    
        function safeTransfer(address _to, uint256 _amount) public {
            if (_to == address(0)) {
                revert UnsafeTransfer(_to);
            }
    
            if (address(_to).balance == 0) {
                revert UnsafeTransfer(_to);
            }
    
            if (balances[msg.sender] < _amount) {
                revert UnsafeTransfer(_to);
            }
    
            balances[msg.sender] -= _amount;
            balances[_to] += _amount;
        }
    }
    

**จากนั้นไป verify + claim 👇👇👇**
