01 — The Problem

Crypto wallets were failing
both sides of their users.

The Core Tension

Crypto wallets existed on a broken spectrum. At one end: maximally complex interfaces built for power users, where security features were buried inside convoluted menus that demanded deep technical literacy. At the other: dangerously simplified apps that stripped out security signals entirely, leaving beginners unable to evaluate the risks of what they were doing.

Neither group was well-served. The result was an industry-wide trust gap — new users stayed out of crypto entirely, while experienced users built brittle workarounds to manage complexity.

The Design Opportunity

The answer wasn't to pick a side — it was to design a system that could serve both simultaneously. A progressive disclosure model: simple and reassuring by default, with the full power of a professional-grade tool available the moment the user needs it.

Sahal Wallet's mission was to make security feel like a feature, not a friction point. In crypto, trust is the product. Every screen had to communicate: "you are in control, you are safe, and we will never let you make an invisible mistake."

Research Insights

INSIGHT 01
The Security Trust Gap
73% of new crypto users cited fear of making an irreversible mistake as their primary barrier to adoption. Wallets looked too technical to trust. Security features read as danger signals rather than confidence builders — the opposite of their intended function.
INSIGHT 02
The Power User Friction
Advanced users managing 10+ assets across multiple chains spent an average of 25 minutes per day just navigating between chains and verifying transaction states. The multichain experience was entirely fragmented — no wallet unified the view without sacrificing depth.
INSIGHT 03
Onboarding Abandonment
Industry-standard seed phrase onboarding had a 68% abandonment rate. The friction of security setup — opaque instructions, anxiety-inducing terminology, no contextual guidance — was driving users away before they ever made a single transaction.

03 — Business Challenges

Core Challenges

The systemic UX and trust barriers preventing mainstream crypto wallet adoption.

🔐

Trust & Security Perception

78% of users cite security as their #1 concern. Existing wallets bury security controls in settings menus, making them feel like danger signals rather than confidence builders.

🔗

Complex Multi-Chain UX

Active traders manage an average of 3.4 wallets across different chains. No wallet has successfully unified multi-chain management without sacrificing depth or clarity.

📚

Crypto Literacy Gap

61% of users abandon wallets due to complexity. Seed phrases, gas fees, and transaction signing remain opaque barriers that block onboarding at every step.

⛽

Transaction Fee Opacity

Users frequently discover total costs only after initiating a transaction. Hidden gas fees and speed options are buried, creating post-transaction regret and eroding trust.

04 — Secondary Research

Market Insights

Wallet Abandonment
61%
Abandon Due to Complexity
More than half of crypto users eventually stop using their wallet due to UX friction — not security failures. Complexity is the primary driver of abandonment across all user segments.
Power User Behaviour
3.4
Wallets Managed on Average
Multi-chain users maintain an average of 3.4 separate wallets because no single product handles all chains well. This creates fragmented UX and increases the risk of user error.
Security Priority
78%
Security as #1 Concern
78% of surveyed crypto users rank security as their top concern when choosing a wallet — but most rate their current wallet's security communication as confusing or anxiety-inducing.

05 — User Stories

What Users Need

As a... I want to... So that... Priority
Crypto Beginner Complete wallet setup in 3 guided steps with clear explanations I feel confident my funds are safe without needing technical knowledge High
Active Trader See my entire portfolio across all blockchains in one dashboard I never have to switch between apps to track my total net worth High

02 — Process

Designing for trust
at every layer.

A five-phase design process anchored in the belief that security UX and usable UX are not opposing forces — that the best wallet is one that builds confidence while its safety mechanisms work invisibly.

01
Web3 User Research
Deep-dive interviews with 32 users across the spectrum — first-time buyers to DeFi power users. Mapped every point of friction, fear, and confusion in existing wallet flows across MetaMask, Trust Wallet, and Phantom.
02
Security-First Architecture
Collaborated with the engineering team to understand the full security model — seed phrases, key derivation, transaction signing. Every IA decision was made with security as a first-class constraint, not an afterthought.
03
Dual-Mode UX Design
Designed a progressive disclosure system — a clean, reassuring default mode for beginners with progressive unlock of advanced views. Tested extensively with mixed-literacy cohorts to validate the handoff point between modes.
04
Visual Language for Trust
Developed the green/dark crypto palette, security iconography system, and premium dark UI language. Visual signals were engineered to communicate "safe vault" rather than "experimental app" — dark luxury meets institutional finance.
05
Wallet Component Library
Built a comprehensive design system: chain chips, asset rows, transaction confirmation flows, seed phrase display components, biometric prompts, and financial data visualization tokens. Every component designed to scale across 12 chains and 500+ assets.

03 — Design

A vault in your
pocket.

Every screen answers one question before the user can ask it: "Is this safe?" The portfolio view unifies 12 blockchains into a single confident number. The transaction confirmation screen shows exactly what will happen — and what it costs — before you commit.

Design Highlights

◈
Portfolio-Unified Multichain Dashboard
12 blockchains collapsed into a single portfolio number in vibrant green. Chain filter chips let power users drill down instantly. No app-switching, no fragmented view — one screen, total control.
🔐
Progressive Security Disclosure
Simple by default, powerful when needed. Security controls are always one tap away but never crowd the core experience. Beginners see a clean portfolio; advanced users unlock deep chain diagnostics.
⇅
Transaction Confirmation with Full Context
Every send screen answers the question "what is this transaction actually doing?" — plain-language contract summaries, fee breakdowns, speed options, and a clear irreversibility warning before signing.
◎
3-Step Educational Onboarding
Seed phrase setup redesigned as a guided, educational flow — not a panic-inducing wall of responsibility. Step-by-step with inline definitions, verification games, and confidence checkpoints.
▲
Real-Time Portfolio Visualization
Live portfolio value with per-chain and per-asset breakdown. Color-coded change indicators in financial green/red. Monospace numerals throughout for precision and scanability.

Design System

Green, dark, and
the language of trust.

Every design token in Sahal Wallet was chosen to communicate one message: this is a financial instrument worthy of your most valuable assets. Dark luxury meets blockchain-native precision.

Green communicates growth and trust — the color of nature, of progress. Deep forest tones ground the interface with premium weight. Financial green and red are preserved from global convention: gain stays green, loss stays red — universal signals users already know.

04 — Impact

Security that builds
measurable trust.

The design outcomes for Sahal Wallet validated a core hypothesis: that making security visible, legible, and confidence-building directly reduces transaction errors and drives adoption among previously excluded user segments.

Reflection

"Sahal Wallet was about making security feel like a feature, not a burden. In crypto, trust is the product. Every design decision — from the confirmation flow to the seed phrase display — was engineered to make users feel in control, not confused."
— Rupesh Chavan, UI/UX Designer
"The best security UX is the kind that builds confidence while doing its job invisibly. If a user feels safe, the security is working. If they feel anxious, the design has failed — regardless of how robust the underlying system is."
