Designing a Multi-Chain NFT Wallet for Web3

I led all design efforts to create a multi-chain NFT wallet that solved interoperability challenges for Web3 users.

The design solutions represent innovative approaches to Web3 UX.

• Create the most NFT-compatible wallet with multi-chain support

• Redefine wallet user experience with intuitive interfaces for crypto newcomers

• Provide added value through intelligent NFT sorting and categorization

• Design a secure yet user-friendly platform for digital asset management

• Build a scalable foundation for future Web3 innovations

There are quite a few blockchain wallets out there—the most well-known being Metamask. With over 21 million monthly active users and its somewhat user-friendly interface, we identified it as the major competition.

Overall, we identified that software wallets tend to be more convenient and I created a moodboard with five other wallets we chose as good points to innovate from: Coinbase, Trust, Coin 98, Phantom and Slope wallet.

NFT holders face significant challenges when managing digital assets across multiple blockchains. Existing wallets were either:

• Limited to single blockchain networks

• Overly complex for non-technical users

• Lacking proper visualization and organization for NFTs

• Not optimized for the unique properties of non-fungible tokens

Our challenge was to create a wallet that could bridge these gaps while maintaining security and ease of use.

Empathise and understand

Walked the team through an activity in which we had to create an empathy map to understand the target persona. We categorized the archetype in a quadrant based on what we understood about the user's thoughts, feelings, actions, and words.

Next was the affinity map. This was going to help us understand the higher level themes and varying opportunities clustered in the quadrant of our persona's thoughts, feelings, actions, and words. This gave a top down outlook on the possibilities of the user experience we could offer.

Empathy and Affinity Maps

Engaged the team in a "How Might We" exercise to craft the challenge statement for the problem we aim to solve with the designed product. We voted on the best statement by getting everyone's opinion on the miro board and using a format of - "problem to solve, business value, and opportunity to leverage". That way, we could clearly see where design meets technology and business needs.

We also had to ensure that we identified success metrics that we would be tracking post release. The UX or HEART metrics specific to the Web3 wallet we were building was as important as the design itself. These include, Happiness, engagement, Adoption, Retention, and Task Success of each feature, screen, and functionality.

Researched inspiring demos of other applications to give a sense of what competitive advantage we were going to leverage for low fidelity sketches.

Led the design team through a Crazy 8 sketching activity in which we had to; in 2 minutes, sketch 8 different mockups that capture the concepts that have been generated from the affinity map and empathy map.

The best ideas were detailed out and collected to be digitized for voting.

Everyone voted via sticky notes the best sketches and then story boards were carefully created for each screen to aid prototyping.

We now had a much clearer definition of what our product's interface was going to comprise of.

Out of the voted upon sketches, low fidelity mockups were created for each screen.

Low fidelity mockups were converted into high fidelity prototypes while incorporating all storyboard elements.

Due to the virtual nature of work, we set up lookback (participate) for review and testing of the fidelity prototypes. The aim was to prepare a usability guide to help checkmark task points and success of interaction.

All tested results were captured and fed back as design requests for further iteration.

With the ethos of the product and some major screens already outlined, I created a design system in order to achieve intuitive and consistent design.

Design System

Despite creating an innovative design that addressed key challenges in the Web3 space, Nebula was ultimately discontinued due to a combination of factors:

• App Store restrictions that limited distribution

• Market challenges during the cryptocurrency bear market

• Unforeseen personal circumstances among the founding team

While the product didn't reach its full market potential, the design work represents valuable innovations in Web3 UX that have since been adopted by other platforms. The project demonstrates how thoughtful design can simplify complex blockchain interactions for everyday users.
