前言

本文全面解析加密钱包从创建到上链的完整闭环：

• 钱包生成：助记词、私钥、地址的派生与恢复
• 链上交互：余额查询、签名、转账、合约部署
• 资产发行：一键创建 ERC-20 同质化代币、ERC-721 非同质化资产

实现钱包创建和导入的实现

实现核心说明：主要借助Ethers实现创建随机钱包和导入现有钱包

• 创建钱包核心代码

<!---->

# 创建随机钱包
import { ethers } from "ethers";
const wallet = ethers.Wallet.createRandom();
console.log("创建钱包地址:",wallet.address)
console.log("创建钱包助记词:",wallet.mnemonic)
console.log("创建钱包私钥:",wallet.privateKey)

• 导入钱包核心代码

<!---->

import { ethers } from "ethers";
# 助记词
const mnemonic=""//助记词
const walletmnemonic = ethers.Wallet.fromPhrase(mnemonic);
# 私钥
const privateKey=""//私钥
const wallet = new ethers.Wallet(privateKey)
console.log("创建钱包地址:",wallet.address)

• 钱包方法说明

如果需要了解更多关于Ethers的内容可以查看作者的另外两篇文章《ethers.js 全栈开发实战：从 Provider 到 Utils 的 6 大核心模块深度解析》、《基于 ethers.js 的区块链事件处理与钱包管理实践指南》

特别说明:React Native 构建app和PC端在使用Ethers时需要在入口文件（index.tsx）中导入import 'react-native-get-random-values';组件才能正常使用

创建代币

实现核心说明：借助solidity和openzeppelin编写合约代码，通过ethers调用合约

• ERC20代币核心代码

  // SPDX-License-Identifier: MIT
  // Compatible with OpenZeppelin Contracts ^5.0.0
  pragma solidity ^0.8.22;
  import {ERC20} from "@openzeppelin/contracts/token/ERC20/ERC20.sol";
  import {ERC20Burnable} from "@openzeppelin/contracts/token/ERC20/extensions/ERC20Burnable.sol";
  import {Ownable} from "@openzeppelin/contracts/access/Ownable.sol";
  import "hardhat/console.sol";
  contract MyToken is ERC20, ERC20Burnable, Ownable {
  constructor(string memory name_,string memory symbol_,number memory amount_,string memory address initialOwner)
      ERC20(name_, symbol_,amount_,)
      Ownable(initialOwner)
  {
      _mint(msg.sender, amount_ * 10 ** decimals());
  }
  
  function mint(address to, uint256 amount) public onlyOwner {
      _mint(to, amount);
  }
  }

• 部署合约

  # 借助hardhat部署
  module.exports = async  ({getNamedAccounts,deployments})=>{
  const getNamedAccount = (await getNamedAccounts()).firstAccount;
  const TokenName = "BoykayuriToken";
  const TokenSymbol = "BTK";
  const {deploy,log} = deployments;
  const Token=await deploy("MyToken",{
      from:getNamedAccount,
      args: [TokenName,TokenSymbol,getNamedAccount],//根据参数不同调整
      log: true,
  })
  // await hre.run("verify:verify", {
  //     address: TokenC.address,
  //     constructorArguments: [TokenName, TokenSymbol],
  //     });
  console.log('合约地址',TokenC.address)
  }
  module.exports.tags = ["all", "token"];

• 关于合约编译、部署、测试：可以参考作者写的另一篇文章《 智能合约开发、测试、部署全流程（实操篇）》，《web3相关知识分享》专栏中也有大量的案例供参考
• Ethers调用合约

  
  import { ethers } from 'ethers';

// 1. 配置 const RPC_URL = 'https://sepolia.infura.io/v3/&lt;YOUR_INFURA_KEY>';//可以通过注册infura获取YOUR_INFURA_KEY const PRIVATE_KEY = '0x你的私钥'; // 测试钱包的私钥

// 2. 合约字节码 & ABI const bytecode = '0x608060405234801561001057600080fd5b50...'; // Remix 编译后复制 const abi = [];//可以通过编译生成json文件中取

// 3. 连接 const provider = new ethers.JsonRpcProvider(RPC_URL); const wallet = new ethers.Wallet(PRIVATE_KEY, provider);//可操作

// 4. 部署 async function deploy() { const factory = new ethers.ContractFactory(abi, bytecode, wallet);//合约地址 const contract = await factory.deploy( 1_000_000, // 发行 100 万枚 { gasLimit: 2_000_000 } ); await contract.waitForDeployment(); console.log('合约地址:', contract.target); } await deploy();

# 创建NFT
**说明**：基本同创建ERC20代币合于大同小异，主要的区别在IPFS存储部分，
关于NFT合约部分可以参考作者的另一篇文章

# 总结
至此，你已掌握加密钱包的完整生命周期：  
从「随机生成 / 助记词恢复」到「私钥-地址派生」，再到「签名、发送交易」。  
更进一步，凭借这些密钥即可在链上 **一键部署并发行** ERC-20 同质化代币或 ERC-721 非同质化资产，实现资产的确权与自由流转。
