AVRIO turns physical screens and the people who pass them into one economy. The result is a network where attention is measurable, rewards are fair, and every payout traces back to a verified scan.

AVRIO: a scan-to-earn ad network on Solana
A blockchain-powered digital out-of-home advertising network where people scan QR codes on real-world screens to earn AX8 token rewards, while advertisers, screen owners and ambassadors share in a transparent, fraud-resilient loop.

The challenge
The problem we set out to solve.
Cronus Digital set out to build AVRIO, a digital out-of-home advertising network where the screens on the street and the people walking past them are both part of the economy. Instead of running ads into the void, every physical screen displays a rotating QR code, and anyone who scans it earns crypto rewards instantly and verifiably.
That meant tying together four very different audiences in one transparent loop: scanners earning tokens, advertisers buying ad slots and tracking performance, screen owners hosting kiosks for a revenue share, and an internal team moderating ads and managing the reward economy.
The hard part was trust. Rewards had to feel instant, but the network could not pay out for fake scans, bots or spoofed locations, and every party needed proof that a real person engaged with a real screen.
The solution
How we built it.
01
Non-custodial mobile app
Built around Solana wallet sign-in with Phantom and Solflare. Users scan an on-screen QR, the deep link opens the app, and a provisional AX8 reward lands in their balance before they are redirected to the advertiser. A live map shows approved billboards, stores and partner screens nearby.
02
QR scan and reward engine
Every scan runs through GPS geo-validation within 100 metres of the screen, impossible-travel velocity checks and device-integrity checks before a reward is credited. No tokens are minted at scan time.
03
Fair, batched reward economy
Rewards stay provisional and are finalised in a nightly batch, where the daily pot is divided by actual scans, so every user in a 24-hour window earns the same fair rate regardless of timing.
04
Unified web portal
One portal for advertisers, screen owners, ambassadors and the internal team: ad upload and approval, AI-assisted screen assignment that avoids placing competitor ads on the same screen, bulk onboarding via CSV, and tiered analytics up to national attribution modelling.
05
Resilient kiosk player
Loops ad creative with a dynamic per-screen QR overlay, keeps playing offline from a local cache, and sends a heartbeat every five minutes so owners can see each screen’s health in real time.
06
On-chain settlement
AX8 reward distribution and a treasury-managed buyback for cashing out, gated by a one-time admin whitelist to keep the swap path clean and auditable.
The benefits
What it unlocks.
Fraud designed out
Geo, velocity and device checks gate every scan before a single token is credited.
Proven attention
Advertisers get blockchain-logged proof a real person engaged with a real screen.
Two-sided marketplace
Scanners, advertisers and screen owners all participate in one transparent loop.
Clean on-chain settlement
Whitelisted treasury buyback keeps the cash-out path auditable and tamper-resistant.
The result
What changed.
≤ 3s
From scan to provisional reward in the user’s wallet.
99.5%
Platform uptime across the kiosk and reward network.
20%
