刚刚开始学习 Solidity 来帮助我的朋友。我想知道您是否可以并且应该在一份合同中包含以下所有内容。
如果可能的话,我正在考虑使用 block.timestamp 来做到这一点。你也可以让我知道你对此的想法吗:)
是的,你可以,
继承openzeppline ERC20代币合约并构建其余部分
import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
import "@openzeppelin/contracts/access/Ownable.sol";
contract YourToken is ERC20, Ownable {
// properties
- presaleStartDate
- presaleEndDate
- icoStartDate
- icoEndDate
- presalePrice
- icoPrice
- whitelistedAddresses
constructor() ERC20("YourToken", "YRTKN") {
_mint(msg.sender, 1000000 * 10 ** decimals());
}
// functions
- whitelistAddress // use this one to set addresses
- buyTokens // used to buy either presale or ico
- setSaleRequirements // used to set all the above properties
- withdrawSalesProfit // you can use this to withdraw money made from sale
}
虽然我不建议在一份合同中构建所有内容,但我希望这会有所帮助
