Why Is DeFi Expensive

What Is Gas

Simple Token Transfer

function _transfer(address sender, address recipient, uint256 amount) internal {
require(sender != address(0), 'Cannot transfer from 0 address');
require(recipient != address(0), 'Cannot transfer to 0 address');
_balances[sender] = _balances[sender].sub(amount, 'Cannot transfer more tokens than you have');
_balances[recipient] = _balances[recipient].add(amount);
emit Transfer(sender, recipient, amount);
}
function _transfer(address sender, address recipient, uint256 amount) internal {
require(sender != address(0), 'Cannot transfer from 0 address');
require(recipient != address(0), 'Cannot transfer to 0 address');
require(amount <= _balances[sender], 'Cannot transfer more tokens than you have');
_balances[sender] = _balances[sender] - amount;
uint256 test = _balances[recipient] + amount;
require(test >= _balances[recipient], 'Addition overflow');
_balances[recipient] = test;
emit Transfer(sender, recipient, amount);
}
