Gamify Your Coins, Grow Your Community
The problem QRBase solves
Most coins and community tokens struggle with two chronic gaps:
-
Zora‑coin Utility & Engagement – Hundreds of new coins appear on Zora every day, but most offer nothing beyond short‑lived hype.
Most Zora coins fade fast, momentum dies.. -
Cross‑community Growth – Projects often build isolated followings with no shared incentives across communities, making meaningful collaboration rare.
How QRBase Fixes This
$SCAN launched as a Zora coin post—but with real, onchain utility from day one.
The idea behind $SCAN is to power #QRBase — a platform that helps creators build utility for their coins.
We onboard @base tokens with dedicated QR pages, each tied to market cap milestones and a reward pool for their community.
The QR code holding the prize is split into 9 blurred pieces, revealed step-by-step to eligible holders, turning it into a gamified experience 🧩
In short, we help grow multiple communities through $SCAN-powered access 🔓
🔍 How QRBase Works?
🎁 $1000 Reward Pool (Round 1)
🧩 We split a QR code into 9 blurred pieces
📈 Each time $SCAN hits a new market cap ($2K → $200K)
🔓 A piece is revealed — only for $SCAN holders (100k+)
🎯 At $200K, all 9 are visible — first 3 to scan win big
⚡️ Speed matters — the faster you scan, the bigger the reward:
🥇 First scan → $500
🥈 Second scan → $300
🥉 Third scan → $200
Feel the moment. 🎥
This is what happens when we reach the final milestone —
The QR code becomes fully visible, and the race begins. 🧩

Challenges we ran into
Challenges I Ran Into
Building QRBase came with several technical and strategic challenges as we scaled from a simple dApp to a growing onchain network connecting multiple communities. Here's a recap of what we tackled:
📦 Market Cap Tracking with KV Storage
We implemented automatic storage of the max Market Cap in Cloudflare KV to avoid unnecessary API calls and ensure consistent milestone tracking.
🖼️ Dynamic Image Switching
We built a system to automatically display QR code visuals and coin images based on live data, removing the need for manual updates.
🔐 API Response Decoding
We developed a custom layer to decode raw API responses from coin info and image sources, ensuring accurate rendering in the UI.
☁️ Securing Market Cap APIs via Cloudflare Workers
To protect the system, we routed all Market Cap updates through Cloudflare Workers. This hides the real endpoints, applies rate limiting, and enforces access control.
📸 Image Display Without Client-Side Counts
We moved logic to Cloudflare Workers or KV so images render properly even if the client doesn’t receive full count data.
🛡️ Protecting QR Code Pieces from Exploits
As we expanded to new communities, protecting QR pieces from unauthorized access became critical. We took steps to secure image access and restrict visibility only to qualified users.
📲 Reward Claims with Coinbase Wallet
#QRBase is powered by @linkdropHQ —A secure system that dispenses tokens one by one.
⚡️First scan, First serve, preventing any user from claiming all rewards.
We chose Coinbase Wallet reward links as the perfect solution for delivering prizes instantly and securely to winners.
🎨 UX/UI Improvements for Multi-Token Support
With new partner communities joining, we refined the user experience—improving layout, responsiveness, and onboarding flow to support more tokens and QR hunts smoothly.
