From community engagement to smart contracts, each layer builds on the next to create truly local Web3 infrastructure.
Smart contracts for urban governance
Layer 2 rollup infrastructure
IoT data processing layer
Community engagement foundation
City-Chains start at the ground level, aligning local stakeholders to define how value flows through their community. It's more than user onboarding, it's digital self-determination.
Encrypted APIs, sensors, weather trackers, and connected vehicles stream city-level data. Off-chain processors verify it using zkProofs; turning local activity into composable, private infrastructure.
Each City-Chain runs on a shared Layer 2 built with Alchemy Rollup infra. It processes execution, batching, and cross-city connectivity; while Ethereum secures finality and global consensus.
Developers can deploy contracts for lending, insurance, voting, or urban analytics. Communities gain new tools; while staying in control of their data, identity, and governance.
Cross-chain transactions across Orbit chains, enabling seamless value transfer between City-Chains.
