Onchain Dev City
@EthCC[9] Cannes 🇫🇷 by Capvise Group
A real-world microcity inside one venue, built for builders.Quests. Demos. Nightlife. Content. On-chain identity.Not your regular side event. A playable city.
🌆What you’ll experience
For one day during ETHCC Cannes, one venue becomes a fully-functional on-chain microcity.
You don’t just “show up.”You mint a City Passport, complete quests across zones, meet high-signal builders and leave with on-chain proof + real pipeline.
The City (zones inside the venue)
🌆 Onchain Street - entry arch + immersive check-in + city soundscape🎯 Quest District - live arcade of on-chain quests + leaderboards + NFT badges🎤 Main Stage - lightning talks, demos, micro-pitches, interactive formats☕ Builder Lounge - deep conversations, guild corners, DAO meetups🍸 Nightlife Zone - music + curated drinks + after-dark networking📸 Content Island - creator pods + live capture zones🗞 Press Hub - interviews, recaps, city updates💻 Digital Layer - Passport NFT, live rankings, on-chain reputation
The Quest Game (why it’s addictive)
Onchain Dev City runs on participation:
✅ Mint your City Passport NFT at entry✅ Complete quests across zones✅ Earn points + badges + on-chain rep✅ Top contributors unlock rewards (hardware wallets, ecosystem grants, collector NFTs)
Every scan and interaction compounds - socially and on-chain.
