DAPP算力质押LP挖矿系统开发
智能合约代码编写好后,点击“Create”按钮部署智能合约到内存中,【181公链2591開发3365微电】并进行调试,如果部署成功,会出现智能合约的函数运行按钮和参数输入框,然后就可以调试你的智能合约了,智能合约的语法和示例可以在Solidity的文档,基本上把这些在线文档看完,已经算精通了,剩下的只是实践编写代码。
我将提供一个基本的以太坊ERC-20代币合约的逻辑代码,这个代码是用Solidity编写的。这个例子是一个非常基础的代币合约,所以只有基本的发行和转移功能。
```solidity
//SPDX-License-Identifier:MIT
pragma solidity^0.8.0;
import" openzeppelin/contracts/token/ERC20/ERC20.sol";
contract MyToken is ERC20{
constructor()ERC20("MyToken"){
//这里的代码可以在合约创建时设置一些初始值
}
function mint(address recipient,uint256 amount)public onlyOwner{
require(msg.sender==owner,"Not owner");
balances[owner]+=amount;
balances[recipient]+=amount;
totalSupply+=amount;
}
function transfer(address recipient,uint256 amount)public onlyOwner{
require(msg.sender==owner,"Not owner");
require(balances[owner]>=amount,"Insufficient balance");
require(balances[recipient]>0,"Invalid recipient");
balances[owner]-=amount;
balances[recipient]+=amount;
totalSupply+=amount;
emit Transfer(owner,recipient,
