October 2021 Development Update

In preparation for the Dexfolio app’s release onto the Google Play Store and Apple App Store, our team has been hard at work making some significant improvements to the Dexfolio app.

We want to share with you the progress we’ve made:

• Completed backend migration to Firestore — a process of over 6 tasks — which allows data from already connected addresses to update instantly.
• Improved backend logic to better handle the refreshing of data that is displayed when addresses are added to the app. Before it was 20+ seconds, and now it’s 1 second.
• we created automated unit tests that check every feature in our app before we merge new code, so we get alerted if the code accidentally breaks any app features
• Added more alert triggers (10% and 25% increases) so you can be even more aware of your token changes.
• Fixed notification logic and a multitude of bugs to ensure you can rely on dexfolio notifications.
• Fixed 20 low to medium severity bugs, ensuring users have a smoother and more reliable experience.
• A number of minor wording and design changes to give a better user experience — including improved display of error messages.
• A variety of backend library updates and code refactoring — allowing for better stability as we continue to develop and expand on Dexfolio’s capabilities.
• Improved handling of unexpected errors — reducing the impact that any errors will have on the usability of the app.

As you can see, some significant development has happened since our last update. With key areas focusing on optimizing refresh speeds, resolving bugs and further improving the usability of the app. Putting Dexfolio in a great position for it’s launch.
