The Web3 ecosystem is expanding at a remarkable pace, attracting everyone from independent developers and bootstrapped startups to established technology giants.
Regardless of your background or the current stage of your Web3 project, having a solid set of development tools is crucial. A well-chosen Web3 development stack significantly reduces development time and helps ensure that your final solution is both robust and reliable.
But what exactly is a Web3 stack, and how do you use it effectively?
This guide breaks down the various layers of the Web3 development stack, explores the essential tools used at each stage, and provides practical advice for building successful decentralized applications.
What Is a Web3 Stack?
A Web3 stack refers to the complete collection of technologies, tools, and protocols required to build, operate, and maintain applications on decentralized networks, primarily blockchains. These applications can include NFT marketplaces, decentralized loyalty programs, and much more.
This development stack includes layers for blockchain interaction, smart contract development, decentralized storage, and user interface design, creating a comprehensive environment for building fully decentralized applications.
Let’s explore the different layers of the Web3 tech stack in detail.
Network Layer
The network layer forms the foundation of the Web3 stack. It consists of the blockchains themselves, which serve as the base infrastructure upon which developers build their applications.
In Web3, blockchains function similarly to servers and databases in Web2 applications—they store a dApp’s business logic and maintain its current state. The key difference is that blockchains are maintained by a distributed network of nodes worldwide, rather than by a single centralized entity.
Developers generally choose between two types of blockchain networks: Ethereum Virtual Machine (EVM)-compatible chains and non-EVM-compatible chains.
EVM-Compatible Blockchains
Ethereum was the first blockchain to enable the development of smart contracts and decentralized applications. It operates on a distributed runtime environment known as the Ethereum Virtual Machine (EVM).
Any blockchain that adopts this same runtime environment is considered EVM-compatible. These chains use Solidity for smart contracts and can execute contracts designed for the Ethereum network, though they may differ in consensus mechanisms, transaction speed, and other features.
Due to Ethereum’s first-mover advantage, the EVM ecosystem boasts the largest community of users and developers, making it a popular choice for dApp development.
Some prominent EVM-compatible Layer-1 chains include:
- Fantom
- Avalanche
- Binance Smart Chain
- Cronos
Non-EVM-Compatible Blockchains
Non-EVM-compatible blockchains operate on their own unique runtime environments and do not natively support Ethereum-based smart contracts. These networks often use programming languages like Rust or C++ instead of Solidity.
Common examples of non-EVM-compatible blockchains include:
- Tezos
- Solana
- WAX
- Algorand
- Cardano
- Aptos
Layer-2 Blockchains
Layer-2 solutions (L2s) are separate blockchains built on top of Layer-1 networks to enhance scalability or introduce new functionalities. They process transactions off-chain before submitting the data to the underlying blockchain, thereby inheriting its security while improving performance.
Notable Layer-2 solutions include:
- Optimism
- Arbitrum
- Polygon
- Lightning Network
Which Blockchain Layer Should Developers Use?
Most developers prefer EVM-compatible chains due to their extensive tooling, robust libraries, and large developer communities. Another advantage is the ability to deploy the same application across multiple EVM-compatible chains with minimal effort, broadening the potential user base.
However, non-EVM chains may be preferable for specific use cases. For example, game developers often choose WAX for its high transaction throughput and specialized support for in-game asset trading.
Blockchain Interaction Layer
This layer enables communication between decentralized applications (dApps) and the underlying blockchain. It supports the deployment, execution, and management of smart contracts, allowing dApps to interact with on-chain business logic.
Key functions include querying blockchain state and sending transactions securely. This layer abstracts complex blockchain operations, simplifying development and improving the user experience.
Nodes
Nodes are essential components of any blockchain network. They validate and relay transactions while maintaining a complete copy of the distributed ledger, ensuring data integrity and network security. A higher number of nodes generally means greater decentralization and security.
Developers have two main options for node access: running their own node or using a node provider service. Self-hosting offers more control but requires significant maintenance and cost. Using a provider simplifies infrastructure management but involves relying on a third party.
Popular node service providers include:
- Infura: Specializes in providing API access to the Ethereum network without requiring users to run a full node. Known for high uptime and features like WebSocket support.
- Alchemy: Offers a comprehensive suite of tools, APIs, and SDKs to simplify node management and provide real-time notifications.
- QuickNode: A Web3 infrastructure provider supporting over 20 networks, including multiple testnets, with an extended set of APIs.
Blockchain Explorers
Blockchain explorers are tools that allow users to search and browse blockchain data, such as transaction histories, account balances, and block details. They pull data from nodes via APIs and present it in a user-friendly format.
Widely used explorers include:
- Blockchair: A multi-cryptocurrency blockchain explorer offering advanced analytics and cross-blockchain search capabilities.
- Blockscout: A block explorer for EVM-based chains that enables users to search transactions, interact with contracts, and verify smart contract code.
- Etherscan: The leading blockchain explorer for the Ethereum network, providing detailed insights into transactions, gas prices, smart contracts, and token information.
Presentation Layer
The presentation layer acts as the bridge between users and blockchain technology, focusing on user interface (UI) and user experience (UX). It abstracts the complexities of blockchain interactions into intuitive front-end components.
Native Libraries
Native libraries provide the essential tools for connecting dApps to blockchain networks. They enable functions like retrieving blockchain data, checking account balances, and sending transactions.
Commonly used libraries:
- Web3.js: The primary JavaScript library for interacting with Ethereum nodes, supporting tasks like transaction sending and contract deployment.
- Ethers.js: A lightweight Ethereum library offering wallet encryption, contract abstraction, and event filtering.
- Web3.py: A Python-based library for Ethereum, facilitating contract deployment, transaction signing, and event logging.
Many developers also use third-party SDKs that automatically detect and interact with common smart contract standards, reducing manual coding and improving efficiency.
Frontend Libraries
Frontend libraries help developers build responsive and user-friendly interfaces for dApps. They ensure a smooth and intuitive experience for end-users.
Popular choices include:
- React.js: A component-based JavaScript library that integrates seamlessly with Web3 libraries, enabling modular and reusable UI elements.
- Angular: A comprehensive framework backed by Google, offering two-way data binding and dependency injection suitable for larger applications.
Developers can extend these libraries with specialized Web3 SDKs that provide pre-built hooks and UI components compatible with EVM-based blockchains.
