SECURE PROVISIONING
Core Capabilities for Device Identity
Chainscore provides the foundational cryptographic identity layer for your IoT fleet, ensuring each device is uniquely, securely, and immutably registered on-chain. This eliminates the risk of spoofing and forms the basis for automated, trustless interactions.
01
Hardware-Secure Key Generation
We provision unique cryptographic key pairs directly into your device's hardware security module (HSM) or secure element. Keys are generated on-device and never exposed, meeting FIPS 140-2 Level 3 standards for tamper resistance.

On-Device
Key Generation
02
On-Chain Identity Registration
Each device's public key is registered as a non-transferable NFT (ERC-721) or Soulbound Token on a chosen L1/L2. This creates a permanent, verifiable identity ledger, enabling permissionless proof-of-ownership and provenance tracking.

Automated Lifecycle Management
Our system manages the entire device lifecycle via smart contracts. This includes automated provisioning, attestation of software integrity, credential rotation, and secure decommissioning with key revocation on-chain.

Cross-Chain Attestation & Interop
Device identities and attestations are made portable across ecosystems using our cross-chain messaging protocol. Prove device status on Ethereum, Polygon, or Arbitrum without re-provisioning, enabling seamless multi-chain dApp integration.

Real-Time Integrity Proofs
Devices generate and submit cryptographic proofs of their software state (e.g., firmware hash) to the identity contract. DApps can verify these proofs in real-time to trustlessly confirm a device is genuine and uncompromised.

Audit-Ready Compliance Logging
Every identity event—from minting to revocation—is immutably logged on-chain with timestamps and initiating authority. This provides a tamper-proof audit trail essential for regulatory compliance (IoXT, GDPR) and security forensics.

END-TO-END SECURE WORKFLOW
Our Provisioning Process: From Design to Deployment
A systematic, auditable process for provisioning cryptographic identities to IoT devices at scale, ensuring security is embedded from the first line of code to the final production rollout.
01
Architecture & Threat Modeling
We design your secure provisioning architecture, mapping the device lifecycle from factory to field. This includes threat modeling for key generation, storage, and distribution to identify and mitigate risks before implementation.
