Build and deploy a verified telemetry sharing system where fleet driving data feeds directly into insurance pricing, giving fleets lower premiums for safer driving. The Device Attestation, External Data Oracles, and Compliance Attestations modules anchor telemetry straight from vehicle devices, so insurers can price on data they can trust.
Turn unverifiable driving exports into attested telemetry an insurer can price against directly.
01.
Prove the data's source. The Device Attestation module signs telemetry at the vehicle device, so insurers know the driving data came from genuine hardware and was not edited in transit.
02.
Guarantee integrity. Each telemetry record is anchored by digest, so any modification of speed, braking, or mileage data breaks its hash and is immediately detectable.
03.
Feed pricing directly. External Data Oracles deliver verified driving metrics into the pricing contract, so premiums adjust from measured behavior rather than self-reported claims.
04.
Reward safe driving. The contract translates verified safe-driving metrics into lower premiums, so fleets see their risk profile reflected in real, evidence-backed rates.
05.
Respect data rules. The Compliance Attestations module confirms telemetry sharing meets the agreed consent and data-handling terms before it reaches the insurer.
06.
Show fleets the basis. Each fleet sees the verified metrics that drove its premium, so pricing is explainable and disputes are settled against a shared record.
Follow fleet telemetry from device attestation through verified delivery to a usage-based premium adjustment.

Cerulea decomposes telemetry pricing into modular contracts. Each layer attests devices, anchors data, checks compliance, and prices risk without either fleet or insurer editing the numbers.
Verified telemetry pricing is a horizontal capability. Here is how different actors put the sharing layer to work.
Share attested driving data to earn lower premiums for demonstrably safe driving, turning telemetry the fleet already collects into a direct, evidence-backed reduction in insurance cost.
Key Asset Types
Price usage-based policies on telemetry they can cryptographically trust, extending fair rates to safe fleets without fear the underlying driving data was edited before it arrived.
Key Asset Types
Deliver device-attested feeds into insurance pricing as a trusted intermediary, so the data their hardware produces carries provable integrity to every insurer consuming it.
Key Asset Types
Whether you are bridging fleet telematics platforms or attesting telemetry directly from vehicle units, Cerulea routes both into one verified record.
For fleets on established telematics platforms. Telemetry and safety events are translated into on-chain verified records through the API gateway automatically.

Building a verified telemetry sharing system with device attestation, tamper-evident anchoring, compliance gating, and usage-based pricing from scratch requires specialised engineers and careful telematics integration. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects telematics and insurance integration benchmarks. Building device attestation, tamper-evident telemetry anchoring, compliance gating, and a usage-based pricing feed for an average program takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your telemetry and pricing rules into pre-audited WebAssembly binaries and provisions the verification and pricing layer instantly.
