TokenPocket市场分析 学习如安在Solidity中创建一个TP钱包

Solidity所以太坊智能合约的编程道话，而创建一个TP（Trustless Payment，即无信任支付）钱包是在Solidity中达成的一个原理而紧要的口头。TP钱包的想法是通过智能合约达成两边之间的无信任支付，确保资金正确发送并确保不会被坏心操作。在这篇著述中，咱们将学习如安在Solidity中创建一个浅易的TP钱包。

当先，咱们需要界说TP钱包的数据结构。咱们不错创建一个`Wallet`合约，其中包含两个地址：发送方和汲取方，以及一个`balance`变量来存储现时余额。代码示举例下：

```solidity

contract Wallet {

One of the key features of Bither Wallet is its trend tool, which provides users with valuable insights into the performance of different digital currencies. This tool allows you to track the price movements of your favorite cryptocurrencies in real-time, helping you make informed decisions about when to buy or sell.

address public receiver;

uint public balance;

constructor(address _sender, address _receiver) {

sender = _sender;

receiver = _receiver;

}

}

```

接下来，咱们需要达成TP钱包的功能，即入款和支款。入款的经由是发送以太币到智能合约的地址，并更新余额。支款则是将余额发送到汲取方的地址。代码示举例下：

```solidity

function deposit() public payable {

require(msg.sender == sender, "Only sender can deposit funds");

require(msg.value > 0, "Deposit value should be greater than 0");

balance += msg.value;

}

function withdraw(uint amount) public {

require(msg.sender == sender TokenPocket市场分析
