Managing your cryptos
has never been so easy.

Ledger is a security expert in cryptocurrencies. The company has developed a unique and disruptive technology for safeguarding crypto assets for individuals and companies. As a leader in the hardware wallet industry, Ledger's competitive advantage is based on their chip technology to secure private keys. One of their most famous products is the Ledger Nano S, a light cryptocurrency hardware wallet that Ledger sold over 1,000,000 units globally.


In Q3 2018, Ledger is planning to launch a mobile app. This is a major opportunity to develop quality software, and make Ledger one of the most influential companies in the cryptosphere, especially if the app is used to help storing cryptos safely as a wallet, and as a powerful portfolio tracker. The app is currently being developed, and the following project is a fictional app that I did in order to explore what could be done from a UX and UI perspective. I don鈥檛 work with Ledger.

My challenge started as a weekend project, with the ambition to create a mobile app that people would be willing to use, in less than a week.


Due to the dynamism of the crypto-sphere, there was plenty of data available to me. Articles, apps, app reviews, social networks data, YouTube videos, and so on. So I used this to accurately define the user base, the way these users behaved and several possible use cases for the app.


With common scenarios in place, I was also able to define personas.



As time was limited, I directly started to draft the app in Sketch, based on some screenshots I had seen of the future mobile app. This allowed me to jumpstart the creative process and be confronted to UX challenges. I took the decision to focus on creating a coherent user experience and make the app appealing to crypto newbies as well as experts.

Crypto enthusiasts check their portfolio trackers (such as Blockfolio) on a regular basis. So my first objective was to create a dashboard that would reflect this behavior. This explains why the Market view is the default view rather than the Operations view. Right after opening the app, users can see the total balance, recent portfolio trends, and market moves.



One major challenge in the app, was to create a simple process to send and receive assets. Users can manage several crypto assets and accounts, so it must be easy to switch between them from the account page. Once an account is selected, sending assets can be done in just three steps. When selecting the target account, users can look for an email address in their phone's contact list, scan a public address, or type in a valid address manually. The third is used to confirm the sending. Once done, a link is shared, allowing users to follow the transaction status.



Here鈥檚 a glimpse into the cryptoassets sending process:
