// Description
TollChain modernizes tolling with blockchain, vehicle NFTs, and on-chain payments. Vehicles are assigned a verifiable digital identity linked to KYC metadata. Tolls trigger automatically via RFID or geo-location smart contracts. The system enables transparent deductions, real-time logs, and fraud reduction. It supports congestion pricing, dynamic tolls, and cross-border interoperability, ensuring users retain identity control and payment privacy.
// Core Features
Vehicle NFTs: Unique on-chain identity for each vehicle with ownership and metadata.
Automatic Toll Payments: Geo-triggered or sensor-based smart contract payment execution.
Tamper-proof Records: Immutable on-chain logs for toll history and vehicle passage.
Dynamic Pricing Support: Enables congestion-based or time-dependent toll rates.
Cross-jurisdiction Access: Interoperable framework for state, national, or international toll networks.
