Какие есть варианты продажи токенов за usdt через смарт-контракт?
function buy(uint256 amount) public {
ERC20(usdt).transferFrom(msg.sender, address(this), amount)
uint256 sent = amount * rate
ERC20(token).transfer(msg.sender, sent)
}
ERC20(usdt).transferFrom(msg.sender, address(this), amount)
uint256 sent = amount * rate
ERC20(token).transfer(msg.sender, sent)
}
