如果您希望在没有后端或任何用户或进行交易的情况下自动出现某些日期时将您的令牌发送给用户，则不可能。如果不使用用户或后端脚本调用事务，则不能执行区块链操作。
您可以编写以下空调合同以获得所需的结果：
用户将稳定的硬币发送到您的空投合同。这些用户的地址应存储在某个地方。您可以自动存储代币买家的地址和数量（在区块链上的数组 -
地址[]买家，uint256 []量）。如果您希望用户单击网站上的按钮以接收可用数量的令牌，则如果呼叫者以前发送了稳定的硬币，则AirDrop合同应具有将适量的令牌发送给呼叫者的方法。此方法应检查，如果
msg.sender在购买者中（检查阵列可能很昂贵，您可以创建买家仅对此检查）以及是否有空调日期（您可以在某个数组中保存时间戳，并通过与block.timestamp进行比较来保存任何日期。如果满足了这两个要求，则合同将从您的余额（转移）或余额（Transfer）从汇率上发送令牌。如果您想自己发送交易以将所有令牌提供给买家，则可以制作方法，只能由您调用（拥有的将非常有帮助）。在此方法中，合同通过
买家数组，然后发送金额[publeerIndex]*交换向每个人交换。此方法不需要用户单击任何按钮，但气体的昂贵，因此对您来说可能非常昂贵。If you want your token to be sent to users when certain date comes automatically without backend or any users or you doing the transactions, it is not possible. Blockchain operations cannot be executed without calling a transaction using scripts by user or backend.
You can write the following airdrop contract to achieve desired result:
Users send stable coins to your airdrop contract. Addresses of these users should be stored in some place. You can store addresses and amounts of token buyers automatically (in arrays on the blockchain -
address[] buyers,uint256[] amounts).If you want users to click on button on website to receive available amount of tokens, your airdrop contract should have a method to send right amount of your token to caller if the caller sent stable coins before. This method should check, if
msg.senderis inbuyers(check in array can be expensive, you can create abuyersmap only for this check) and if airdrop date has come (you can save timestamps in seconds in some array and check if any date has come via comparison withblock.timestamp). If both requirements are met, contract sends tokens from your balance (transferFrom) or from its balance (transfer) following the exchange rate.If you want send the transaction by yourself to give all tokens to buyers, you can make the method, which can be called only by you (Ownable will be very helpful). Inside this method, contract goes through
buyersarray and sendamount[buyerIndex]*exchangeRateto each of them. This method doesn't require users to click on any buttons, but can be very expensive in gas and hence for you.
