βAfter our Successfull Edition @ Devconnect Argentina
βCapvise Group is back at EthCC[9] Cannes with Onchain Dev City Cannes Edition.
βOnchain Dev City
β@EthCC[9] Cannes π«π· by Capvise Group
βA real-world microcity inside one venue, built for builders.
βQuests. Demos. Nightlife. Content. On-chain identity.
βNot your regular side event. A playable city.
βπWhat youβll experience
βFor one day during ETHCC Cannes, one venue becomes a fully-functional on-chain microcity.
βYou donβt just βshow up.β
You mint a City Passport, complete quests across zones, meet high-signal builders and leave with on-chain proof + real pipeline.
βThe City (zones inside the venue)
βπ Onchain Street - entry arch + immersive check-in + city soundscape
π― Quest District - live arcade of on-chain quests + leaderboards + NFT badges
π€ Main Stage - lightning talks, demos, micro-pitches, interactive formats
β Builder Lounge - deep conversations, guild corners, DAO meetups
πΈ Nightlife Zone - music + curated drinks + after-dark networking
πΈ Content Island - creator pods + live capture zones
π Press Hub - interviews, recaps, city updates
π» Digital Layer - Passport NFT, live rankings, on-chain reputation
βThe Quest Game (why itβs addictive)
βOnchain Dev City runs on participation:
ββ
Mint your City Passport NFT at entry
β
Complete quests across zones
β

βEvery scan and interaction compounds - socially and on-chain.
βWho should come
βBuilders, hackers, engineers
βFounders shipping infra/tools/protocols
βEcosystem & devrel teams

βA previous edition during Devconnect Argentina was:
βAnchored by a leading ecosystem partner (quests + stage + digital layer co-designed)
