Hedgehog is a time-based prediction product that transforms on-chain signals into simple, fast decisions, removing the complexity of traditional market interactions.
Hedgehog is an on-chain prediction product that transforms complex blockchain signals into fast, repeatable decision loops. Instead of relying on real-world events or traditional trading mechanics, the product focuses on on-chain metrics, funding rates, fees, block activity, allowing users to participate in short, time-based prediction rounds.
I led the product design end-to-end: owning the system logic, information architecture, interaction flows, design system, and interface delivery across desktop and mobile. My primary challenge was translating mechanics that are inherently technical and abstract into an experience that feels immediate, legible, and engaging, even for users without a trading background.
This case documents not just what was built, but why: the research behind the decisions, the paths that were considered and discarded, and what we learned along the way.
The crypto prediction market space has been growing, Polymarket, Augur, and various DeFi protocols have proven the concept. But engagement is consistently limited to experienced users: people who understand orderbooks, liquidity mechanics, and on-chain concepts.
The fundamental problem isn't that people don't want to predict. It's that every existing platform asks users to understand the system before they can engage with it.
Current landscape problems:
As a result, participation is either limited to experienced users, or becomes too passive to be meaningful.
On-chain data moves continuously and is verifiable by anyone. Funding rates, transaction fees, block activity, these signals fluctuate in real time and are not tied to external events that require waiting days or weeks for resolution.
The opportunity: build a prediction product around on-chain signals, with short time windows, so participation is simple, cycles are fast, and outcomes are immediate.
This wasn't about building a simpler version of an existing product. It was about rethinking what participation in a prediction market could feel like if it was designed for engagement rather than financial sophistication.
This was the design challenge. Not just 'simplify the UI,' but redesign the participation model itself so that the mechanics are learnable in seconds and the experience feels rewarding from the very first round.
Main pains to solve:
The product needed to serve two distinct user profiles simultaneously, and the tension between them shaped most of the design decisions.
User Type 1 — Curious newcomer
User Type 2 — Experienced DeFi participant
''The design challenge: make it simple enough for the newcomer without feeling shallow to the experienced user. The solution was progressive disclosure, simple surface, accessible depth.''
The research approach combined competitive analysis, behavioral benchmarking, and pattern analysis from analogous products, focusing on understanding why existing prediction and trading interfaces fail to scale engagement beyond experienced users.
Competitive benchmarking, 6 platforms analyzed:
Key insights extracted:
These insights converged on a clear direction: reduce participation to one decision, shorten the cycle, make outcomes immediate, and expose behavior (not just data) as a decision signal.
The design process moved through four phases: IA definition, interaction design, visual system, and iterative testing. Below are the five most significant design decisions, including the alternatives that were considered and discarded.
Decision 1 — Pooled system (UP/DOWN) vs. orderbook
Decision 2 — Time-based rounds vs. continuous market
Decision 3 — Showing participation data publicly
Decision 4 — Single dominant action vs. multi-step flow
Decision 5 — Resolution feedback design
The product is structured as a continuous loop across four states. Each state was designed with a specific emotional and functional goal. Every screen exists to move the user efficiently to the next state in the loop.
The loop: Enter position → Wait for resolution → Receive outcome → Enter next position.
Front State — The Moment of Decision
The entire interface is organized around a single question: UP or DOWN? The dominant price display, the 'price to beat' reference, and the two action buttons occupy the visual center. All secondary information, round timer, pool stats, historical data, is present but visually subordinate. The user never has to search for what to do.
Participation State — Social Proof as Signal
Instead of abstract market data, the product exposes participation directly: top participants, capital distribution, position imbalance (UP vs DOWN). This turns passive data into an active decision-making input. experienced users can read the imbalance as a contrarian signal, while newcomers use it as social validation.
Waiting State — Transparency Under Tension
After entering a position, the user waits for resolution. This phase required its own design attention: the waiting state needed to communicate progress without creating anxiety, and maintain engagement without allowing new entries. Countdown timers, clear system state labels, and locked-but-visible position data were the primary design solutions.
Resolution State — Close the Loop, Trigger the Next
The win/loss resolution phase is the highest-emotion moment in the product. The design amplifies positive outcomes and acknowledges negative ones, neither dismissing nor dwelling. The immediate 'Cash Out' or 'Play Again' CTA routes that emotional energy into the next action. This was the single highest-impact design decision for retention.
The visual system was built to support the product's core principle: clarity under pressure. Prediction markets involve money, time pressure, and uncertainty, the interface can't add visual noise on top of that.

Design system impact:
UI simplification without system simplification doesn't work.
Showing behavior is more powerful than showing data.
The resolution phase is the product's most important screen.
Progressive disclosure requires explicit prioritization decisions.
AI-assisted workflows change the speed of exploration, not the quality of decisions.
