How to build the Personal finance management app in 5 minutes using React and Blockmate Web3 API

There are over 300+ million Web3 users and the average user has 3.5 wallets. So, the need for apps that can give users power over their digital assets is clear.

Many Web3 products are inaccessible or difficult to use for the average customer, so it’s essential to build Web3 apps at the same standard as traditional finance.

Blockmate’s Web3 API provides you with the tools you need to build high-quality personal finance management solutions. We’ve created a simple Personal finance management app to showcase what our solution can offer and inspire you to build your own Web3 Super apps of the future. Check it out here → to see it in action.

Our API can be used to build Web3 personal finance apps at the same quality as users have come to expect. Give your users access to 24 months of historical data across multiple accounts in a clear and accessible manner, as well as rich financial overviews and detailed breakdowns. Create investment apps and all-in-one money management tools that give users control over their finances.

In this guide, you’ll learn how to use our API solution in a few simple steps. You’ll be able to clone our app for free and use it as a foundation for your app ideas. Ready? Let’s get started.
