Hey guys,
I´ve just started to learn myself into making an own cryptocurrency. I´ve been playing around with some random coins and I just found this code from some github:
pragma solidity ^0.8.2;
contract Token {
mapping(address => uint) public balances;
mapping(address => mapping(address => uint)) public allowance;
uint public totalSupply = 10000 * 10 ** 18;
string public name = "My Token";
string public symbol = "TKN";
uint public decimals = 18;
event Transfer(address indexed from, address indexed to, uint value);
event Approval(address indexed owner, address indexed spender, uint value);
constructor() {
balances[msg.sender] = totalSupply;
}
function balanceOf(address owner) public returns(uint) {
return balances[owner];
}
function transfer(address to, uint value) public returns(bool) {
require(balanceOf(msg.sender) >= value, 'balance too low');
balances[to] += value;
balances[msg.sender] -= value;
emit Transfer(msg.sender, to, value);
return true;
}
function transferFrom(address from, address to, uint value) public returns(bool) {
require(balanceOf(from) >= value, 'balance too low');
require(allowance[from][msg.sender] >= value, 'allowance too low');
balances[to] += value;
balances[from] -= value;
emit Transfer(from, to, value);
return true;
}
function approve(address spender, uint value) public returns (bool) {
allowance[msg.sender][spender] = value;
emit Approval(msg.sender, spender, value);
return true;
}
}
As this is already a working code I wanted to know if this is even a safe code I can use to further develop it or if there are better solution.
Also I wanted to add a tax function on transaction if anyone could share how that works 
I also want that some of the tokens get sent to a different wallet that automatically distribute out coins to people that complete a task or stake. Any idea how to do that? Would be awesome to hear some replys !
