COZ has announced that MONOPOLY Experience: Tesouros do Brasil, a Hasbro-licensed immersive attraction opening Sept. 16 in São Paulo, Brazil, will use the Neo blockchain as its underlying technology infrastructure.

The 90-minute attraction is the largest mainstream brand deployment on Neo to date, with blockchain operating entirely in the background. Visitors take part in an interactive financial and gaming experience without needing cryptocurrency wallets, seed phrases, or gas payments. The approach reflects a broader shift in the blockchain industry toward "invisible" infrastructure use cases, where consumers interact with distributed ledgers through conventional products — tickets, cards, or games — without any exposure to tokens or crypto mechanics.

Neo N3 maintains the real-time state of physical player cards — including balances, room progress, decisions, and reward eligibility — turning the blockchain into an invisible backend for a mainstream entertainment experience. COZ, the developer behind the deployment, is a longtime ecosystem tooling team in the Neo community, known for building wallets, SDKs, and indexing infrastructure for the network.

The attraction is located at Shopping Cidade São Paulo on Avenida Paulista and occupies two floors containing five themed Treasure Rooms, each representing one of Brazil's major regions: North, Northeast, Central-West, Southeast, and South. Visitors receive RFID-enabled investor cards that allow them to progress through the rooms, making investment decisions involving Brazilian tourist destinations and experiencing gains or losses based on those choices.

Physical cards connected to on-chain game state

Each physical card operates as a non-fungible item endpoint on Neo N3. The blockchain serves as the authoritative record for each card, maintaining its initial M$200 balance, current room progression, decisions, and reward eligibility.

As visitors move through the attraction, individual stations communicate directly with the smart contract layer. The stations read information from the cards, apply specific game mechanics — such as balance deductions and probability-based treasure selections — and record the resulting changes on the blockchain.

After a visitor completes the experience, the card is reset on-chain in a single transaction, allowing the same card to be immediately prepared for another participant without requiring a new digital record or separate backend process.

The architecture lets multiple vendors and operational points verify card balances and reward redemptions directly against the blockchain, reducing reliance on a shared centralized database and limiting opportunities for client-side manipulation. This shared-source-of-truth model is one of the practical arguments for blockchain in multi-party venue operations, where several independent operators need to trust the same card state.

The attraction is expected to run through November. Tickets are priced at R$50, with Nubank customers receiving a 15% discount. Presales for Nubank customers began Aug. 4, followed by general ticket sales on Aug. 6.

Reusable blockchain hardware targets high visitor volume

The deployment uses ITEM Systems' AeroGlyph hardware, NFC-enabled cards designed for high-throughput physical environments. A total of 500 AeroGlyph cards will circulate among visitors throughout the activation.

Rather than functioning primarily as souvenirs, the cards are deployed as reusable operational infrastructure. Their on-chain state can be reset after each session, allowing them to cycle continuously through attendees.

COZ estimates that the attraction could generate approximately two million blockchain transactions during its operating period. The model is designed to accommodate additional cards without requiring a fundamental redesign of the backend infrastructure.

The project is officially licensed by Hasbro and was created by Businessland, the production company behind an immersive Harry Potter theater experience in Brazil. It is presented by Nubank through Instituto NU, its social-impact initiative focused on education, technology, and entrepreneurship, in partnership with Brazil's Ministry of Culture. The involvement of Nubank — one of the world's largest digital banks and a major force in Brazil's fintech market — alongside a federal government partner underscores how the project sits within a broader Brazilian push into digital innovation and financial education.

The deployment also extends ITEM Systems' focus on experiential and gaming applications. It follows the company's collaboration with Iron Studios at CCXP25 in December 2025, another licensed-brand deployment involving its technology.

For COZ, the MONOPOLY attraction provides a large-scale example of blockchain being used in a physical consumer environment rather than as a financial product. Its multi-month operation and reusable card infrastructure demonstrate how blockchain-based game state can support high-volume, real-world brand experiences while remaining largely invisible to consumers. Whether similar licensed-brand blockchain backends become a recurring pattern for venue-scale entertainment — where verifiable shared state and reusable hardware offer operational advantages — is a question the project's performance through November may help inform.
