INTRODUCTION

Designing an app in 1 month for Solana's Hackathon

I joined a hackathon's team as product designer and designed PetNet mobile application in one month. The mobile app mints pet passports as NFTs and exposes them via QR so identity and medical records are verifiable instantly. The goal was to create a reliable flow for owners, finders, and veterinarians and validate the concept.

OUR IDEA

Mobile first verified pet passports on Solana

We mint each pet passport as an on-chain NFT and expose it via QR for instant verification by owners, veterinarians, and finders. The Android first app uses Solana Mobile Stack and Mobile Wallet Adapter to enable native wallet flows and direct on-chain interactions.

USER RESEARCH

We reached out to a friend who is veterinarian + pet owner to guide us through the problem space

Since we lacked time for a proper user research, we called a veterinarian friend to understand what would simplify his workflow. From his perspective, pet owners fall into patterns. Many are motivated by responsibility and want to ensure their pets receive the best possible care. They keep vaccination booklets in drawers, often forgetting to bring them to appointments. Some try to store medical PDFs on their phones but lose track in 90% of the cases.

Another group likes to travel. For them, crossing borders with pets is stressful, as it requires printed certificates, health checks, and passports that vary by country. Their fear is being stopped at customs without proper documents or facing expensive delays. A secure digital passport gives them confidence that all information is valid and instantly verifiable.

Finally, there are owners motivated by community and technology. They like trying new tools, want to show off their pets with profiles, and see value in features like ownership transfer or QR-based recovery if a pet is lost. Their fear is that traditional systems are outdated and cannot guarantee trust or protection if records are lost or falsified.

QR CODES

Two flows to bring lost pets back home

Our system supports both the finder and the owner. For the finder, the experience is simple: scan the QR code on the pet’s necklace, see basic details like name, breed, and age, and tap one button to call the owner.

Pet finders just scan the QR code and call the owners immediately

For the owner, the app provides an emergency flow. When they realize their pet is missing, they can send an alert with the pet’s photo to everyone in their local community. People nearby receive the notification in their app, so they know what the dog looks like. Together, these two flows create a safety net where both the community and technology work to reunite pets with their families.

MANAGE PROFILES

Central hub for pet identity and health management

Simple CRUD system

Each pet profile can be updated with medical history, award, pedigree, and transferred if the pet changes ownership. This structure gives owners a reliable hub for identity, health, and ownership while keeping the system simple to user.

PEDIGREE PROBLEM

Managing incomplete family data for pets

Introducing temporary account for pedigree purposes

We faced a challenge when building family pedigrees: most parent pets will not have a PetNet account or NFT passport. To solve this, we introduced two options. Owners can either link an existing parent with a PetNet account by scanning a QR code or manually create a temporary account for the parent. This allows the pedigree to stay complete while maintaining accurate ownership and medical data, ensuring the family tree can be expanded as other pets join the network.

VETERINARIAN FLOW

Simple link-based reporting for veterinarians

We struggled with how to include veterinarians without asking them to install an app or create an account. Our solution was to let owners generate a secure link from the app and share it however they prefer. The vet opens it on a computer, selects the type of intervention, adds a title, and uploads a PDF. This way we captured medical history on-chain without disrupting their routine.

REFLECTION
Understanding blockchain technology better with design

I deepened my understanding of Solana and blockchain basics, learning how decentralized storage and verification shape design constraints.

Growth in Collaboration

I improved at working with engineers by asking the right questions, aligning UI decisions with technical feasibility, and adapting to feedback.
