Web3 developers not only need programming skills but also the ability to simplify life or improve work efficiency through programming. In the crypto field, with specific programming skills and accumulated practical experience, you will gain:
High-paying positions in companies
The ability to automate critical tasks in work or track large amounts of data
Understanding of product development technologies
We often see developers earning substantial income by creating bots or other software, typically in the range of six to eight figures.
This article will guide you on how to start learning Web3 development and the programming languages you need to know.
Learning programming through practice, with the right opportunities, will help you achieve your goals faster than others.
I have been passionate about programming since childhood, initially to explore technology and develop critical thinking skills, and later as a tool to achieve greater goals.
Let's get started now.
Definition of Web3 Developers and Why Learn Web3 Development?
Web3 developers are capable of handling everything from smart contracts to backend and frontend development. They need to understand how to automate specific processes and typically have the ability to quickly resolve critical issues.
The main reasons to learn Web3 development include:
Setting up automated tasks and solving various types of problems.
Auditing, using, or modifying existing software.
Participating in projects or building projects independently to earn high salaries.
Acting as white hat hackers, finding vulnerabilities and profiting from them.
Personally, I learned Web3 development for personal growth and to build my own products, but I want to emphasize:
To stand out in the Web3 industry, you must understand its technical and economic principles, which will be embedded in developers' daily work through smart contracts or rollups.
Despite the numerous speculative opportunities in the crypto market, developers are still actively building and earning high salaries through development.
Web3 developers are fewer in number, so the level of competition in the industry is not high, offering more job opportunities compared to traditional industries.
Next, let's delve into the salary levels that Web3 developers can expect.
Web3 Developer Salaries
If developers can master backend development and Solidity (or Rust) development, their average salary typically ranges from $5,000 to $20,000 per month. If you can join a medium-sized project and are not in a management position, this salary level can serve as a reference.
One of my friends freelances on Twitter, providing automated auditing services. His monthly income can sometimes reach $50,000, which is also a noteworthy case.
I found that the highest return obtained by white hat hackers is around $10 million. In 2022, Wormhole's core bridge paid a white hat hacker approximately $10 million. Typically, security vulnerabilities are difficult to measure solely in monetary terms; the value of time saved is also immeasurable.
By using various software tools, I save 5-7 hours of work time each day. Therefore, mastering programming and software technologies will significantly improve work efficiency and save time.
Additionally, most useful Web3 applications lack clear and concise user interfaces, so understanding how to launch and improve them is crucial.
What Programming Languages Do You Need to Learn?
In the Web3 industry, programming languages are a significant part of the job. Each task may require different programming languages, so it's essential to understand the purpose of each:
Python
Python is the best programming language for creating automation programs.
Its use cases in Web3 include:
Very suitable for writing automation scripts (airdrop scripts, MEV monitoring, other tasks)
Used as the backend for dApps (except for dApps built with FastAPI or Django)
Very suitable for data science (e.g., collecting statistics from dApps)
Why is it your best choice right now?
Easy to get started; for me, it's one of the simplest programming languages.
A wealth of ready-made learning materials (YouTube, forums, other platforms)
A large number of ready-made Web3 libraries that simplify software building.
Overall, Python is a language very suitable for learning how to automate daily tasks or collect basic data.
Basic Skills in Backend and Frontend (HTML, CSS, JS)
This part is the most basic requirement for a project, as the UI is the first impression left for users.
Even if you understand all the details of smart contracts or backend, it is still not enough, as frontend aspects like wallet signatures are directly related.
JavaScript plays the most crucial role here and must be mastered, while basic knowledge of HTML and CSS is usually sufficient.
Its use cases in Web3 include:
Understanding the structure and properties of websites to integrate wallet signatures or other Web3 tools.
Conducting various tests on the content built in the backend.
Solidity
Solidity is one of the primary development languages in the Web3 industry, and almost all smart contracts are built with it.
It can be said to be the "origin" of Ethereum smart contracts.
Its use cases in Web3 include:
Used for Ethereum L1 and almost all EVM-compatible L2s (ARB, OP, Base, etc.)
Also used to build L3 solutions.
Basically, all DeFi and NFT projects are related to it.
It is the most valuable language in Web3, but it also presents some challenges. One of the main issues is that it is very difficult to learn, and the risk factor in work is quite high; simply forgetting to write a function can put the entire protocol at risk, resulting in millions of dollars in losses from liquidity pools. The benefit is that Solidity developers' salaries are quite high.
Rust
Almost all blockchains that are not EVM-compatible require the use of the Rust language.
Its use cases in Web3 include:
Building projects on Solana, Cosmos, Near, Polkadot, etc.
Used by snipers and MEV.
Overall, it is a cool programming language, but its learning resources are even scarcer than those for Solidity. In this case, your best learning materials will be ChatGPT and official documentation.
How to Start? An Efficient Path from Zero
I started with learning Python and JavaScript, which for me were the sacred foundations before entering the Web3 industry.
They provide a good foundation for understanding key concepts and how code works, after which I began learning other programming languages.
I developed a launch plan with ChatGPT to complete the first step:
Learn the Basics of Programming
Our goal: Get accustomed to code syntax and programming logic.
Best resources:
"Python for Everybody" on Coursera:
CodeAcademy's "Learn JavaScript":

Learn through practice:
Security and Testing
Next, your task is to delve deeper and continue testing.
Only practice can yield real results; there are no shortcuts in Web3 coding, and life is the same.
Read various blogs about Web3 coding and maintain curiosity.
Most importantly, always check the security of your code.
Review every line of code on the webpage; this is absolutely crucial.
Make sure to try applying this knowledge to your own practice.
Start automating and make coding a part of your daily life.
Once you get started, you can almost try development work in any field.
AI is also very helpful in this regard, and below I will share how to use AI to enhance learning and work efficiency.
Start learning and building, and over time, you will surely succeed.
How to Use AI in Learning?
AI is the best tool to optimize and accelerate Web3 coding learning.
I personally often use ChatGPT, but there are other AI tools that can perform equally well or even better.
What kind of problems can be solved with AI:
I ask for explanations of complex topics.
I request code examples to solve specific problems.
I check for bugs or errors in the code.
If I can't find a solution, I always turn to AI for help.
I ask myself what else I should learn to solve problems faster.
If you only learn alone without communication or improvement avenues, the difficulties you encounter will be much greater.
Now, when you encounter a problem you can't solve, you just need to use ChatGPT to outline clear steps to help you resolve it, rather than having it solve it for you.
If AI is always writing code for you, you won't understand the structure or specific workings of these functions.
Combining the learning platforms I shared, continuous practice, and using AI to solve your own problems is one of the most effective ways to achieve results and become top talent.
How to Find Your First Job: "Beginner's Checklist"
If your goal is to become a developer, this is the best way to understand what you need to learn.
All you need to do is find a junior position on Web3.career or crypto.jobs.
Then, look at the job requirements and think about what else you need to learn.
Example of a junior Web3 developer job listing:
Understand Solidity and write smart contracts.
Familiarity with JavaScript/TypeScript, React.
Familiarity with Hardhat / creating tokens.
Understand ERC standards (ERC-20, ERC-721).
Understand basic blockchain concepts (transactions, gas, DeFi).
Ability to use Git and GitHub.
Write down everything listed in the job postings and check each point one by one.
Then, have AI simulate the HR interview process and generate typical interview questions.
This way, you can stress-test potential questions and prepare answers before the interview.
TL;DR
When the market is sluggish, the best approach is to cultivate skills that can generate income.
We are in a high-risk field, and objectively speaking, those without stable income often struggle to achieve final results.
Because they cannot fully seize opportunities when they arise.
Becoming a Web3 developer is one of the best choices.
Using programming and truly understanding it can give you an advantage.
Most importantly, you can earn a considerable salary and have the ability to create your own projects.
For example, I am a construction worker, and if I want to scale my business several times or even dozens of times, it is almost impossible to do so with my original strategies alone.
Maybe you have a developer friend who can help you.
But you still need a basic understanding, so you won't be deceived in the process.
Formulating programmatic strategies for daily repetitive tasks is also a crucial part.
Create bots to complete tasks or improve efficiency.
AI can help you find different opportunities.
Now you have time, make the most of it.
If a developer earns more in a month than you do in three years…
Isn't that worth thinking about?
Think about it, but don't just think.
If your answer is "Yes, indeed"…
Then the best approach is to start learning programming today.
