Overview: My Summer at Tip

During the summer of 2018, I worked as a UX/UI Design Intern for Tip Blockchain. With the support of my team, I researched and designed features for KasaKasa, Tip's user-friendly mobile wallet app. Additionally, I assisted in UX research, helping craft surveys and usability studies.

KasaKasa

Creating the most user-friendly platform in the cryptocurrency economy.

The Problem

While it is easier to use cryptocurrency today, it still takes a degree of technical knowledge: Private keys, public keys, hashed wallet addresses, syncing, nodes, are some of the terms new users have to familiarize themselves with. These are hurdles to adoption that have undoubtedly slowed the uptake of cryptocurrencies by the masses.

How can we design a wallet app for cryptocurrency that is usable by anyone?

My Design Process

Below is an outline of my design process. Overall, they are iterative, I tend to go back and forth between each stage to make sure I formulate the right question to be solved and address all aspects of the design problem.

Solution

"Search and Discovery," "Peer-to-Peer Instant Messaging," and "Send and Receive Transactions over Chat" feature of the KasaKasa mobile-wallet application.

Who are we designing for

In order to design for the users, it is necessary to figure out who they are. Because we initially had no data collected on our users, we utilized surveys, interviews, and other resources to better understand who we are designing for. We determined our primary users were: 

  1. People who have basic knowledge, if not at all, of cryptocurrency.

  2. People who utilize their mobile phones to carry out financial transactions.

Understanding the User

In order to better understand how users viewed cryptocurrency and how well they know, I carried out interviews and surveyed customers of a local coffee shop who insisted that they had some experience with cryptocurrency before.

Key Findings

1) Many experience unnecessary friction when trying to send someone a cryptocurrency transaction. In order to receive the payment, the recipient had to send her address hash by copying, pasting and send it to the sender over text messaging, another messaging app, or by email. These additional steps to initiate a transaction created unnecessary frustration.

2) Many made mistakes of sending a cryptocurrency transaction to the wrong address before.

3) People could never memorize their own hash address, forcing them to log in every time a transaction is necessary to check the address. 

With our findings, we identified a persona we would be designing for:

The Overarching Problem

After getting to know our users and analyzing the current problems in the industry, I realized that people were having difficulty understanding the technology and dealing with unnecessary complexity in something that should be easy: paying someone else. I narrowed the problem to:

How can we design an app that makes  cryptocurrency transactions easier and incorporate the app into people's everyday life?

Wireframes

With what we found out about our users, I needed to determine what features to keep, create, or get rid of as well as come up with the flow and navigation.
