What is Web3 Development? 3 Key Web3 Job Types

As you explore the possibilities of a career in Web3 space, you might notice that different job postings often have varying requirements for the same "Web3 Developer" title.

In this article, we'll break down the three main types of Web3 programming roles to help you navigate the Web3 development world and find the right path for you.

1. Protocol Developers

Protocol developers are responsible for creating and maintaining the core protocols of blockchain platforms. They focus on improving aspects such as security, scalability, and performance.

These developers often have a strong background in programming languages like Rust, Go, or C++, as well as a deep understanding of blockchain fundamentals, cryptography, and distributed systems.

Common requirements for Blockchain Protocol Developers:

  • Programming languages: Rust/Go/C++
  • Cryptography libraries: OpenSSL/Libsodium
  • Networking libraries: libp2p/gRPC
  • Consensus algorithms: Proof of Work/Proof of Stake/Delegated Proof of Stake

2. Smart Contract Developers

Smart contract developers create self-executing contracts with the code embedded directly on a blockchain. They ensure that transactions between parties follow specific rules and conditions.

These developers should be proficient in languages like Solidity or Vyper and have a strong understanding of blockchain platforms such as Ethereum.

Common requirements for Smart Contract Developers:

  1. Smart contract languages: Solidity/Vyper/Rust
  2. Blockchain platforms: Ethereum/Polygon/Solana/Binance Smart Chain
  3. Development tools: Truffle/Hardhat/Remix
  4. Testing frameworks: Mocha/Chai

3. Blockchain Application Developers

Blockchain application developers build decentralized applications (dApps) that interact with blockchain platforms and smart contracts. They can specialize in either backend or frontend development, or both.

Backend developers focus on the server-side logic of dApps, handling data storage, smart contract integration, and API development.

They should be skilled in languages such as Node.js, Python, or Ruby and have experience with database management and server architecture.

Common requirements for Web3 Backend Developers:

  • Server-side languages: Node.js/Python/Ruby/Go
  • Database management: PostgreSQL/MongoDB/MySQL
  • API development: REST/GraphQL
  • Blockchain libraries: Web3.js/Ethers.js

4.2. Frontend Developers

Frontend developers work on the user interface and user experience (UI/UX) of dApps. They ensure that users can interact seamlessly with the underlying blockchain and smart contracts.

Frontend developers should be proficient in technologies like JavaScript, HTML, and CSS and have experience with frameworks like React, Vue or Angular.

Common requirements for Web3 Frontend Developers:

  • Web development technologies: JavaScript/TypeScript/HTML/CSS
  • Frontend libraries/frameworks: React/Angular/Vue
  • UI component libraries: Material-UI/Ant Design/Bootstrap
  • State management: Redux/MobX/Vuex
  • Blockchain libraries: Web3.js/Ethers.js


In summary, if you're interested in pursuing a career in Web3 development, it's important to understand the three main job types:

  • Protocol developers
  • Smart contract developers
  • Blockchain application developers

Take the time to identify your strengths and interests and choose a path that aligns with them. Then, focus on developing the necessary skills and knowledge, such as programming languages and blockchain fundamentals, to succeed in your chosen role.
