A decentralized usage-based insurance platform leveraging DIMO's vehicle telemetry data and Cartesi's off-chain computation capabilities to provide dynamic insurance premiums based on driving behavior.
The platform consists of three main components:
- Smart Contracts: Solidity contracts for policy management and premium calculations
- Cartesi Coprocessor: Off-chain computation engine for risk assessment
- Frontend: React-based web interface for policy management
