从技术角度来讲,智能合约被认为是网络服务器,只是这些服务器并不是使用IP地址架设在互联网上,而是架设在区块链上。从而可以在其上面运行特定的合约程序。 但是与网络服务器不同的是,所有人都可以看到智能合约,因为这些智能合约的代码和状态都在区块链上(假设区块链是公开的)。而且,与网络服务器不同的是,智能合约不依赖某个特定的硬件设备,事实上,智能合约的代码由所有参与挖矿的设备来执行。 assert recipient!=self #param max_eth_sold Maximum ETH purchased as intermediary. #param deadline Time after which this transaction can no longer be executed. #param exchange_addr The address of the exchange for the token being purchased. #return Amount of Tokens(self.token)sold. public def tokenToExchangeSwapOutput(tokens_bought:uint256,max_tokens_sold:uint256,max_eth_sold:uint256(wei),deadline:timestamp,exchange_addr:address)->uint256: return self.tokenToTokenOutput(tokens_bought,max_tokens_sold,max_eth_sold,deadline,msg.sender,msg.sender,exchange_addr) #notice Convert Tokens(self.token)to Tokens(exchange_addr.token)and transfers #Tokens(exchange_addr.token)to recipient. #dev Allows trades through contracts that were not deployed from the same factory. #dev User specifies maximum input and exact output. #param tokens_bought Amount of Tokens(token_addr)bought. #param max_tokens_sold Maximum Tokens(self.token)sold. #param max_eth_sold Maximum ETH purchased as intermediary. #param deadline Time after which this transaction can no longer be executed. #param recipient The address that receives output ETH. #param token_addr The address of the token being purchased. #return Amount of Tokens(self.token)sold. public【更全面的开发源码搭建可V or TG我昵称】 def tokenToExchangeTransferOutput(tokens_bought:uint256,max_tokens_sold:uint256,max_eth_sold:uint256(wei),deadline:timestamp,recipient:address,exchange_addr:address)->uint256: assert recipient!=self telegram电报快速咨询点击此通道:https://t.me/ch3nguang return self.tokenToTokenOutput(tokens_bought,max_tokens_sold,max_eth_sold,deadline,msg.sender,recipient,exchange_addr)
