Building in Public an Open Source Solana Wallet Cross-Platform App with Expo, Web3 & React Native

Motivations

As a developer I’ve been interested in the Blockchain space for long time and although a few years ago I started to learn Solidity for fun I didn’t build something real.

At the beginning of the year instead of jumping to a new job I decided to take some time off and move to a quiet place to work on personal projects and learn new things.

Web3 and Blockchain have been always around and I didn't started to build something until I read about Solana.

From Solana website:

It can process 50,000 transactions per second (TPS) at a cost of less than $0.01 per transaction! So it makes perfect to start building dApps.

How it Started?

This journey started having a coffee in one of my favorite spots here in the island when I was reading about Solana and Web3.

After read a few NodeJS examples to do the basic operations like create a wallet, get the balance, request an airdrop or transfer tokens I decided that I need to do something more visual to can put everything together.

And that's it! A Wallet App came to my head. It isn't the most original project but it looked like a good project to start building and understand the whole process from generating a wallet to execute a transaction.

In less than a week, while doing other things, I've been able to Build a fully functional Cross-Platform Solana Wallet App with Expo, React Native and @solana/web3.js.

The feedback received in Twitter was great! So I published the full code on my Github because I think it could be a good starting point to someone that want to start learning and building with Solana and Web3.

What's next

Although, I've built the MVP there is still a lot of work to do so I plan to continue the development and post flequently here about all the process.
