使用下面的 Solidity 代码,我尝试通过智能合约将以太币发送到以太坊钱包地址0x1 ,但它失败了。但是,当我尝试直接从我的钱包向地址0x1发送以太币时,它就成功了。
pragma solidity ^0.4.24;
contract Transfer {
constructor () public payable {
// Deploy contract with 1000 wei for testing purpose
require(msg.value == 1000);
}
function done() public {
address(0).transfer(1); // Transaction success
}
function fail() public {
address(1).transfer(1); // Transaction failed
}
function send(address account) public {
account.transfer(1); // Transaction success (except 0x1)
}
}
为什么我们不能通过合约将以太币发送到地址0x1 ?

直接从我的钱包发送以太是成功的 https://ropsten.etherscan.io/tx/0x1fdc3a9d03e23b0838c23b00ff99739b775bf4dd7b5b7f2fa38043056f731cdc
done() 函数成功 https://ropsten.etherscan.io/tx/0xd319c40fcf50bd8188ae039ce9d41830ab795e0f92d611b16efde0bfa1ee82cd

更新:
在研究了以太坊预编译合约之后,我在solidity代码下面编写了这个代码,以通过智能合约将以太币发送到0x1地址并且它正在工作。
pragma solidity ^0.4.24;
contract Learning {
constructor () public payable {
// Deploy contract with 1000 wei for testing purpose
require(msg.value == 1000);
}
function test() public returns (bool) {
// Set minimum gas limit as 700 to send ether to 0x1
transfer(0x0000000000000000000000000000000000000001, 1, 700);
return true;
}
function transfer(address _account, uint _wei, uint _gas) private {
require(_account.call.value(_wei).gas(_gas)());
}
}
为了测试,只需部署1000 wei的合约并执行test()
函数。它正在工作:)
