Core Insights - The article provides a detailed guide on the development process of Web3 systems, emphasizing the integration of decentralized applications (dApps) with smart contracts and traditional front-end interfaces [1][3]. Group 1: Development Stages - The development of Web3 systems consists of three main stages: smart contract (back-end) development, front-end (user interface) development, and the interaction between the two [3]. - Smart contracts serve as the "back-end logic" of Web3 systems, being immutable and automatically executed [4]. - The front-end is responsible for the user interface, wallet connection, and invoking smart contracts [5]. Group 2: Key Considerations - Defining the core use cases for Web3 applications is essential, such as DeFi lending, NFT marketplaces, or decentralized identity verification [6]. - Selecting the underlying blockchain platform (e.g., Ethereum, Solana, Polygon, or Binance Smart Chain) will determine the programming languages and tools used [6]. - Recommended development tools include Hardhat or Truffle for smart contract compilation, deployment, and testing, and MetaMask as the most common browser wallet for front-end connections [6]. Group 3: Coding and Security - Smart contracts should be written in Solidity for EVM-compatible chains, with front-end frameworks like React, Vue, or Next.js used alongside UI libraries [6]. - Security best practices must be strictly followed to prevent common vulnerabilities such as reentrancy attacks and integer overflows [6]. - Comprehensive unit testing should be conducted using frameworks provided by Hardhat or Truffle, ensuring high code coverage to minimize post-deployment risks [6]. Group 4: Deployment Process - The deployment process involves selecting a test network (e.g., Sepolia or Mumbai) and using private keys and RPC endpoints to send Bytecode to the test network [6]. - After successful testing, the final version of the smart contract is deployed to the mainnet, and the front-end code is hosted on decentralized storage platforms or traditional cloud services [8]. - Code auditing by a professional third-party security team is crucial to identify potential vulnerabilities before mainnet deployment [8].
