Understanding technical topics such as Account Abstraction 4337 can be hard . Many guides and explanations are too long, confusing, and hard to follow .
In this article, I’ll show you how I made sense of it in an easy way . Let’s go through this topic together, making it simple and clear for everyone .
Deep Dive Preparation

Before we get into the details of Account Abstraction 4337, there’s a really helpful series you should read. Check out this from Alchemy: Alchemy’s Account Abstraction Series . It’s full of good info to help you understand what we’ll talk about.
I recommend reading it a few times to get the basics down . It’s a great first step and will make our deep dive easier to follow. Once you’ve got that, you’ll be all set to jump into the more technical stuff with me .
Let’s Get Technical!

When I started looking into Account Abstraction 4337, I checked out a lot of code from big web3 companies . But I found out something important:
Too Complex: These codes had a lot of extra stuff in them. They weren’t just about Account Abstraction 4337. They had their own special parts and business ideas, which made them really hard to understand for beginners .
What we really need is something much simpler ✨. A basic, easy-to-understand code that’s all about Account Abstraction 4337. This way, we can learn the basics without getting confused by the extra complicated parts.
But don’t worry! I found a much simpler repo that’s perfect for us: Mohamad Hammoud’s Account Abstraction Repo . It’s clear and focused just on Account Abstraction 4337. This is where we’ll start our deep dive. It’s a great place to learn the basics without all the confusing extras.
A Quick Heads-Up: Before we begin, it’s important to have some familiarity with Solidity and the Hardhat development framework. This knowledge will help you understand the repo and what we’re going to cover much better .
Ready to dive in? Let’s explore this repo together and make sense of Account Abstraction 4337 step by step! ♂️
First Step: Jump into the ‘Test’ Folder

Let’s start our adventure in the ‘test’ folder. Look for the ‘helpers’ folder there.
In ‘helpers’, you’ll find files that show us how to sign, fill, and pack users operations. It’s like learning the basics first!
If we see a file about a smart contract in ‘helpers’ let’s just take a quick look at it. No need to understand everything yet, just a little peek!
Understanding ‘helpers’ is our first big step. It helps us get ready for everything else in Account Abstraction 4337!
Second Step: Let’s Check Out ‘entrypoint.’
Next, in the ‘test’ folder, we’re going to look at a file named entrypoint.test.ts
.
Easy Steps to Follow:
- Read Every Part: Go through
entrypoint.test.ts
slowly, looking at each line and each function. It’s like following a simple trail. - Follow the Functions: When you see a function, go see what it does. If that function talks about other functions, go check those out too! It’s like following clues in a game.
- Connect with Solidity: If you see that the code is using a method from the entry point in Solidity, go look at that Solidity code too. And there, do the same thing — follow each function one by one. It’s like putting together pieces of a story.
This is a fun way to see how everything in Account Abstraction 4337 is linked together, like a chain of clues in a mystery story.
Third Step: Exploring More Files Just Like Before ️
Now, after entrypoint.test.ts
, we’ll do the same thing with some other files in the ‘test’ folder. It’s like using the same map to explore new places!
Here are the files we’ll check out:
simple-wallet.test.ts
deposit-paymaster.test.ts
paymaster.test.ts
How to Explore:
- Read and Follow: Start with
simple-wallet.test.ts
. Read each line and function, just like we did before. Remember, it’s like following a story. - Function to Function: If a function takes you to another function, keep going. Follow each part of the code like clues in a detective story.
- Solidity Side Trips: If any code in these files links to a Solidity file, take a quick trip there. Follow the story in the Solidity code, and then come back to where you were in the test file.
After these files, feel free to explore any other file that catches your interest. The key thing is to keep following this pattern. It’s like sticking to a winning strategy in a game.
Conclusion

What a journey it’s been diving into Account Abstraction 4337! We started with the ‘helpers’ folder and then ventured through various test files like entrypoint.test.ts
and simple-wallet.test.ts
. Here’s a good way to make the most of what we’ve learned:
A Day-by-Day Approach:
- Day 1: Focus on ‘Helpers’: Take your entire first day to explore the ‘helpers’ folder. No rush, just take it in at your own pace.
- Day 2: Recap ‘Helpers’ and Introduce ‘Entrypoint’: Start with a quick review of ‘helpers’, then move on to
entrypoint.test.ts
. This way, you’re building on what you learned the day before. - Day 3: Combine ‘Helpers’, ‘Entrypoint’, and ‘Simple Wallet’: Go over ‘helpers’ and
entrypoint.test.ts
again, and then addsimple-wallet.test.ts
into the mix. Each day, you’re adding a little more to your knowledge.
Taking your time and spreading out your learning over several days helps everything sink in better. It’s like letting each piece of knowledge settle before adding more.
I hope this method helps make everything clearer and easier to understand. Remember, the best way to learn is at your own pace, one step at a time.
Thanks for being a part of this learning adventure. Keep exploring, and enjoy every step of your journey in tech!
