智能合约所以太坊区块链上的攻击构成部分TokenPocket稳定币支持，它不错自动扩充合约中设定的规定。在本教程中，咱们将学习奈何使用Solidity编程道话构建一个基本的TP（TokenPay）钱包智能合约。

第一步是创建一个新的Solidity文献，并界联络约的称号为“TPWallet”。接着，咱们需要界联络约中的变量和函数。最初，咱们需要界说一个mapping类型的变量，用于存储用户的余额。代码如下：

```solidity

pragma solidity ^0.8.0;

contract TPWallet {

mapping(address => uint) public balances;

}

```

在上头的代码中，咱们界说了一个名为“balances”的mapping变量，它将存储每个用户的余额，其中地址是键，余额是值。

接下来，咱们需要界说进款和支款函数。进款函数会加多用户的余额，支款函数会减少用户的余额。代码如下：

```solidity

function deposit() public payable {

balances[msg.sender] += msg.value;

}

function withdraw(uint amount) public {

require(balances[msg.sender] >= amount, "Insufficient balance");

payable(msg.sender).transfer(amount);

In the case of Bither Wallet, it is important to note that it is a non-custodial wallet. This means that users have full control over their private keys, which are used to access and manage their funds. Bither Wallet does not store users' private keys on its servers, giving users complete control over their funds.

The first step in using Bither Wallet for cross-chain transfers is to install the wallet on your device. Bither Wallet is available for both mobile and desktop devices, and can be downloaded from the Apple App Store, Google Play Store, or the Bither Wallet website. Once you have downloaded the wallet, follow the on-screen instructions to set it up and create a new wallet.

balances[msg.sender] -= amount;

}

```

在上头的代码中，deposit函数用于向指定地址进款，并将存入的金额添加到用户的余额中。而withdraw函数用于从指定地址支款，并将支款的金额从用户的余额中减去。

终末，咱们还不错添加一个函数来取得用户的余额。代码如下：

```solidity

function getBalance() public view returns(uint) {

return balances[msg.sender];

}

```

通过以上身手，咱们顺利地构建了一个粗陋的TP钱包智能合约。在实质应用中，咱们不错进一步膨大该合约，添加更多功能，比如转账、稽察交往纪录等。

追想一下TokenPocket稳定币支持，本教程先容了奈何使用Solidity编程道话构建一个基本的TP钱包智能合约。若是你念念深远学习智能合约开垦，不错赓续探索更多高档的功能和时代。但愿本教程能匡助你更好地意会和诓骗智能合约技末！
