Garvit KhatriHow to store private keys securely in local storage?
I recently started working on a chrome-extension wallet compatible with 4337, you can read more about it here. One of the challenges in creating a wallet is how to store private keys securely in the local storage of the browser. In this blog, I will be exploring how Metamask & Tally-ho wallet stores their private keys. I hope you and I both will learn during this exploration. If we want the data to be encrypted with a password & then stored, the best standard to use is AES-FCM. The crypto API...
Garvit KhatriThe current state of Account Abstraction
GM Everyone! I have a couple of motivations to write this blog. Firstly, to help you understand what all work is pending for the wide adoption of EIP-4337. Secondly, tell you about how you can help in accelerating the process by contributing.The flow of a userOperation in EIP-4337Above is how EIP-4337 makes smart contract wallets a reality. We can start developing smart contract wallets, paymasters, etc compatible with EIP-4337 with a relayer service today. But for it to become the norm & com...
Garvit KhatriThe beginning - EPF #1
Gm! I am super excited to share that I will be participating in the Ethereum Protocol Fellowship (EPF). This blog is my first update for the fellowship.What will I work on?We are moving closer towards the finalisation of EIP-4337. A lot of effort by the core team has been put into designing the contracts, mempool, DOS protections etc. But the team haven't had time to properly support UserOps through one of the browser extension wallets. In this cohort, I intend to work on making a user-f...

I recently got selected for batch 2022 for Polygon Fellowship’s Builders Track. Here are my answers & the projects that I submitted in my proposal.
Post the application I was invited for a virtual interview, here are the things we discussed
My web2 journey so far
What motivated me to explore web3
What all things I have tried in terms of development in web3
Why I proposed the following projects in my proposals
What research have I conducted so far while writing the proposals & am I aware of other people who might be working towards a similar idea
The conversation was mostly fluid and interactive.
What would you consider to be your standout project? Something which you're really proud of or had fun building
It is difficult to choose a single project, I have fun building a lot of things in my past. I feel, there is one project that I enjoyed a lot though, this was 8086 Microprocessor Emulator. Back in college, while studying Engineering Physics in 2014, I was fascinated to study about 8086 processors. It made me wonder if we could emulate the entire processor in a web browser since computers are much faster now. Using this would enable me to write some assembly code and explore the different types of programs with it mimicking the Silicon Valley era of the 1970s. With this goal of mine, using Javascript I started writing the emulator which would run in a sandbox memory (this included runtime memory, registers & segments) environment & allow emulating all the 8086 opcodes. I ensured that architecture was composable for other emulators to be built in future, while 8086 was the first one to be supported. Each emulator would have a command interface, where each command would take arguments as operands and memory. And each command would either set or get a type of memory (runtime, register or segment). Each command state along with the latest memory snapshot was also saved in the backend so that it can be loaded from any previous predefined state. While tinkering and being able to emulate small programs, this project also allowed me to think at the architectural level.
Why are you applying to the Fellowship and what do you hope to take away from it? [in more than 300 words]
Open source communities have been one of the major reasons for my growth in the past. Back in 2014, I started my open source journey with KDE’s Season of KDE fellowship program and then was admitted to the Google Summer of Code 2015 fellowship program. These two programs have helped me accelerate my career, and build a deeper understanding of software architecture and I expect the same from Polygon Fellowship.
Post the acquisition of my last venture, I have been diving deep into Web3 and running experiments to understand it better. Currently, I am exploring opportunities in web3 where I can contribute or build the infrastructure which will help other DAPPS grow faster. Polygon is the most prominent L2 and with a great Defi ecosystem, can definitely help me with the right mentors to accelerate my learnings and goals. I expect to find such mentor(s) who will accelerate my growth & open doors to new technologies/infra that are in the development stage. My goal is to have a successful project at the end of the Fellowship, a deeper understanding of web3, and solve a real problem faced by others.
