TokenPocket是一款闻明的数字货币钱包诈欺,辅助多种主流数字货币的解决与往复。除了数字货币解决功能外,TokenPocket还提供了智能合约的诞生和部署功能TokenPocket代币合约,让用户不错在我方的钱包中编写并执行智能合约。
TokenPocket App本教程将率领读者从零开动,使用TokenPocket内置的Solidity编写用具,编写一个浅薄的智能合约,并在测试汇注上部署并测试合约的功能。
领先,翻开TokenPocket诈欺并导航到智能合约模块。在创建新合约时,咱们需要给合约起一个名字,并选拔合乎的 Solidity 版块。然后,咱们不错开动编写合约的代码了。
让咱们以一个浅薄的投票合约为例。这个合约将允许用户发起一个主题,并让其他用户对该主题进行投票。合约的代码如下:
```Solidity
pragma solidity ^0.4.18;
contract Voting {
mapping (bytes32 => uint8) public votesReceived;
bytes32[] public candidateList;
function addCandidate(bytes32 candidateName) public {
candidateList.push(candidateName);
The primary concern with Bither Wallet is its security features. While Bither Wallet claims to use advanced security measures to protect users' funds, there have been reports of security breaches and vulnerabilities in the wallet's code. These vulnerabilities could potentially expose users' private keys and allow hackers to access their funds.
One of the key features of Bither Wallet is its emphasis on security. The wallet uses a two-factor authentication process to verify transactions, adding an extra layer of protection for your assets. Additionally, Bither Wallet stores your private keys on your device, rather than on a centralized server, further enhancing the security of your funds.
}
function totalVotesFor(bytes32 candidate) view public returns (uint8) {
require(validCandidate(candidate));
return votesReceived[candidate];
}
function voteForCandidate(bytes32 candidate) public {
require(validCandidate(candidate));
votesReceived[candidate] += 1;
}
function validCandidate(bytes32 candidate) view public returns (bool) {
for(uint i = 0; i < candidateList.length; i++) {
if(candidateList[i] == candidate) {
return true;
}
}
return false;
}
}
```
这个合约界说了一个投票合约,其中包含了添加候选东说念主、投票和查询票数的功能。读者不错左证我方的需求修改和扩张这个合约。
接下来,咱们点击“编译”按钮,编译咱们的合约代码。如若莫得乌有,不错点击“部署”按钮将合约部署到测试汇注上进行测试。
部署完成后,咱们不错调用合约中的函数进行测试。比如添加候选东说念主、查询候选东说念主票数、对候选东说念主进行投票等操作。
通过这个浅薄的例子TokenPocket代币合约,读者不错了解到怎么使用TokenPocket内置的Solidity编写用具编写智能合约,并在测试汇注上进行部署和测试。但愿这篇教程对读者有所匡助,让世界更深远地了解智能合约的诞生和诈欺。
