The Problem
Crypto wallets ask users to do something deeply uncomfortable, hand over control of their money to software they don't fully understand. Most wallet UI responds to this by looking like every other fintech product by being flat, clinical, interchangeable. That sameness just avoids the problem rather than build trust build with that opportunity. SlimeWallet was designed to answer the question: what if the interface itself communicated that this product was built with intention?
Research Approach
The research began from direct personal experience as a crypto enthusiast and was extended through App Store and Trustpilot reviews across Trust Wallet, MetaMask and Coinbase Wallet, three of the most widely used non-custodial wallets in the market. The goal was to find the emotional patterns underneath the complaints, what users were actually feeling when things went wrong and what the interface was doing to make those feelings worse. Three patterns emerged consistently across hundreds of reviews that shaped every design decision in SlimeWallet
User Persona
This user has heard enough about crypto to be interested but carries real fear about getting something wrong. He is neither a developer nor a DeFi power user. He is someone moving meaningful money into a product he don't fully understand yet, trusting the interface to tell him when he's doing something right and when he’s doing something wrong without making him feel like a mistake could cost everything. Users like him exist at every step of the wallet journey, during onboarding when they’re entering a seed phrase for the first time, during wallet import when they type a word wrong and see a red screen, during backup when they're confirming they understand the risks they're accepting. Most wallet UI were designed for users more confident than this user. SlimeWallet was designed for this user specifically.
Trust Wallet, MetaMask and Coinbase Wallet all make the same visual assumption. Flat, clinical interfaces with conventional fintech styling. White/Black backgrounds, standard sans-serif type, red error states. The design language communicates neutrality rather than intention. Neutrality just avoids the problem rather than build trust with the opportunity . When a user is handling real money in software they don't fully understand, a neutral interface gives them nothing to hold onto, it doesn't signal that the people behind the product took it seriously, everything just looks like every other fintech product from the last five years. The gap in the market was a feeling, no existing wallet was designed to feel considered, physically weighted and emotionally calm at the moments that mattered most
1) Red error states amplify fear at the worst moment so i removed red entirely from all error states and designed a muted, calm, atmosphere that encouraged users to try again across failure states.
2) Seed phrase input feels fragile and frightening so each word slot was designed as a an elevated component so it feels placed and not typed, a deliberate decision not to be fragile
3) Users don't genuinely understand what they're agreeing to during backup so i designed 3 explicit checkboxes to actively engage users, the continue button is withheld until all three are checked.
4) Flat clinical interfaces signal indifference so i designed a dark ambient atmosphere, inner shadows, recessed surfaces. Every element has physical weight so the product looks like someone cared about building it
