Simplifying Defi Products into a Scalable Experience

Company

Notional Finance, Defi's top leveraged yield protocol.

My Role

UX researcher, UX/UI design, UX testing, Webflow development

Timeline

6 months

Redesigned Notional’s product experience around leveraged vaults, consolidating multiple fragmented offerings into a single, streamlined interface. The new structure significantly simplified the user journey, reduced decision friction, and created a scalable foundation for future vault expansion. The solution received strong internal adoption and replaced several legacy product flows.

Context

Notional Finance is a DeFi protocol that enables users to earn yield through lending strategies and structured financial products.

This project marked a major product shift:

  • Moving away from multiple product types (fixed lending, variable lending, borrowing, liquidity provision)
  • Consolidating the experience into leveraged vaults
Users
  • Crypto-native users seeking yield
  • Advanced users comfortable with leveraged strategies
  • Users comparing risk/reward across opportunities
Business Model
  • Protocol generates revenue through vault participation and activity
  • Incentives (token rewards, points) drive user engagement
Why this project mattered

The previous product experience created:

  • Too many decision points
  • Fragmented navigation across multiple pages
  • High cognitive load when comparing options

This led to:

  • Confusing user journeys
  • Drop-offs during product selection
  • Difficulty scaling as more vaults were introduced

The Problem

Before this redesign:
  • Vaults and products were spread across multiple pages
  • Users had to navigate between different product types
  • Comparison required mental effort across screens
  • Information density made decisions intimidating
Key symptoms:
  • High bounce rates
  • Sporadic and inconsistent user flows
  • Friction when choosing where to deposit
  • Confusion around rewards and strategy differences
Core problem:

Users couldn’t easily compare options or confidently choose a vault.

My Role

I was the sole product designer on this project.

Responsibilities included:

  • Defining the structure of the vault browsing experience
  • Partnering with co-founders to determine key metrics and hierarchy
  • Designing desktop and mobile UX
  • Leading iteration cycles based on internal testing
  • Working directly with engineering on feasibility
  • Building ~90% of the final page in Webflow

Constraints

  • No-code limitations (Webflow) created technical constraints on layout and interactions
  • Small engineering team required efficient, scalable solutions
  • Highly complex financial data needed to be simplified without losing meaning
  • Product needed to scale to 20+ vaults over time

Strategy & Thinking

Insight

Users don’t struggle with too few options—they struggle with comparing too many complex options.

Hypothesis

If we centralize vaults into a structured, comparable format, users will:

  • Make faster decisions
  • Better understand differences between vaults
  • Be more likely to deposit
Key Design Decisions

1. Table view for desktop
- Enables efficient comparison across multiple vaults
- Aligns with industry patterns for financial products
- Scales cleanly as more vaults are added

2. Carefully selected columns (not everything)
Included:

  • Vault name + type
  • Deposit token
  • TVL / liquidity
  • Rewards (APY, incentives, points)
  • Max APY

- Focused on decision-driving metrics, not exhaustive data

3. Filters above the table
- Allows users to quickly narrow options by:

  • Deposit token
  • Strategy type
  • Reward type

- Reduces overwhelm and supports intent-driven browsing

4. Project tooltip (not full section)
- Kept contextual information accessible but not dominant
- Prioritized decision-making over deep exploration

5. Banner for orientation
- Provided lightweight explanation without slowing users down

Desktop → Mobile Transformation (Key Focus)

The Problem

Tables work well on desktop, but on mobile:

  • Horizontal scrolling breaks usability
  • Dense data becomes unreadable
  • Comparison becomes overwhelming
The Solution: Card-Based Mobile Design

Converted each vault into a scannable card format.

Each card includes:

  • Vault name and type
  • Deposit token
  • Rewards and APY

Removed:

  • TVL
  • Project tooltip
  • Some filtering options
Why This Works
  • Prioritizes legibility over completeness
  • Supports quick scanning and tap interactions
  • Reduces cognitive load on smaller screens
Key Principle

Desktop = comparison
Mobile = clarity and quick decisions

Process

Step 1: Wireframing

Started with low-fidelity layouts to:

  • Define table structure
  • Prioritize columns
  • Establish hierarchy

Step 2: Iteration & Testing
  • Collaborated with co-founders to refine metrics
  • Ran internal testing on:
    • Vault selection flow
    • Navigation from landing → vault → transaction
  • Iterated multiple times to reduce friction

Step 3: Build & Implementation
  • Designed final UI in high fidelity
  • Built ~90% of the experience directly in Webflow
  • Solved multiple no-code limitations through custom workarounds

Step 4: Mobile Design
  • Designed mobile after desktop (75% desktop users)
  • Reworked layout entirely into card system

Final Solution

The final experience includes:

1. Intro Banner
  • Brief explanation of vaults
  • Sets context without slowing users
2. Filter System
  • Deposit token
  • Strategy type
  • Reward type

- Enables quick narrowing of options

3. Vault Table (Desktop)
  • Clear, structured comparison across all vaults
  • Focus on decision-critical metrics
  • Scalable for future growth
4. Mobile Card System
  • Simplified representation of each vault
  • Optimized for readability and interaction

Design Principles Applied

  • Comparison-first design
  • Clarity over completeness
  • Scalability for growth
  • Contextual complexity (progressive disclosure)

Results

  • Simplified overall product experience by consolidating multiple offerings
  • Reduced friction in the vault selection process
  • Strong internal feedback from product and leadership
  • Established a scalable system for future vault expansion

While external metrics were not captured due to timing, the redesign:

  • Improved product clarity
  • Reduced decision complexity
  • Created a more cohesive user journey

Reflection

What I’d improve
  • Add analytics to measure:
    • Conversion to deposits
    • Filter usage
    • Vault comparison behavior
  • Test different mobile layouts for deeper comparison
  • Explore hybrid table/card solutions for tablet devices
What I learned
  • In complex financial products, comparison is the product
  • Desktop and mobile require fundamentally different approaches
  • Constraints (like Webflow) force better prioritization and clarity
