TokenPocket冷钱包

Solidity所以太坊平台上使用的一种智能合约编程言语，不错用于创建去中心化诈欺（DApps）中的智能合约。在本教程中，咱们将先容奈何使用Solidity创建一个浮浅的以太坊钱包，该钱包不错用来发送和接纳以太币（ETH）。

1.创建一个新的Solidity智能合约文献，定名为SimpleWallet.sol，并在文献中添加以下代码：

```

By downloading Bither Wallet, users can enjoy the peace of mind that comes with knowing their digital assets are safely stored offline. This reduces the risk of falling victim to cyber attacks and hacking attempts, which have become increasingly common in the world of cryptocurrencies.

Bither Wallet is a user-friendly cold wallet that offers a high level of security for storing Bitcoin and other cryptocurrencies. With its simple and intuitive interface, users can easily manage their digital assets without compromising on safety. The wallet supports multiple cryptocurrencies, including Bitcoin, Ethereum, and Litecoin, making it a versatile choice for investors with diverse portfolios.

solidity

pragma solidity ^0.8.0;

contract SimpleWallet {

address public owner;

constructor() {

owner = msg.sender;

}

function sendETH(address _receiver, uint _amount) public payable {

require(msg.sender == owner, "Only owner can send ETH");

require(address(this).balance >= _amount, "Insufficient balance");

payable(_receiver).transfer(_amount);

}

receive() external payable {}

}

```

2.保存文献后，使用Solidity编译器编译Solidity合约。在得胜编译后，您将获取一个ABI（Application Binary Interface）和一个合约地址。

3.使用Remix或其他以太坊智能合约部署器具将合约部署到以太坊收罗上。

4.在部署合约后，您不错使用以下代码创建一个浮浅的用户界面来与钱包合约交互：

```javascript

const web3 = new Web3("https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID");

const contractAddress = "YOUR_CONTRACT_ADDRESS";

const abi = // Your ABI here

const contract = new web3.eth.Contract(abi, contractAddress);

// Send ETH function

function sendETH() {

const receiver = document.getElementById("receiver").value;

const amount = document.getElementById("amount").value;

contract.methods.sendETH(receiver, amount)

.send({from: web3.eth.defaultAccount})

.on('receipt', function(receipt){

alert("ETH sent successfully!");

});

}

```

5.将上述代码镶嵌到您的网页中，这么用户就不错输入接纳者地址和金额，然后点击“发送ETH”按钮来进行往来。

通过以上措施，您仍是得胜创建一个浮浅的以太坊钱包TokenPocket市场分析，不错用于发送和接纳以太币。请疑望，这仅仅一个浮浅的示例，本色诈欺中可能需要更多的功能和安全性措斀。但愿这个教程大约匡助您初学Solidity智能合约编程。
