IoT Device Secure Key Provisioning
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Security-First Development: Code written in
Solidity 0.8+usingOpenZeppelinlibraries and audited patterns. - Comprehensive Testing: Unit, integration, and fork testing on
HardhatorFoundryto ensure reliability. - Gas Optimization: Every contract is analyzed for efficiency, reducing user transaction costs by up to 40%.
- Full Deployment Support: We handle deployment to
EVMchains (Ethereum, Polygon, Arbitrum) with verification and initial configuration.
We don't just write code; we deliver the foundational logic your entire dApp depends on, with an emphasis on audit readiness and long-term maintainability.
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.
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-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.
Business Outcomes: Secure, Scalable Operations
Our IoT key provisioning service delivers enterprise-grade security and operational efficiency, enabling you to scale your connected device network with confidence.
Automated Device Onboarding
Provision cryptographic identities for thousands of devices per minute via secure, automated APIs. Supports batch provisioning and integration with existing manufacturing or MDM workflows.
Multi-Protocol Key Lifecycle
Full lifecycle management for keys across Ethereum (EOA/4337), Solana, Cosmos SDK chains, and IoT-specific protocols like LoRaWAN. Includes rotation, revocation, and archival policies.
Auditable Compliance & Logging
Immutable, granular audit logs for every key operation (generate, sign, revoke) with SIEM integration (Splunk, Datadog). Built for SOC 2 Type II and GDPR compliance requirements.
High-Availability Global Deployment
Deploy redundant provisioning nodes across multiple cloud regions with automated failover. Guaranteed 99.95% uptime SLA for the provisioning API, backed by 24/7 monitoring.
Custom Security Policy Engine
Define and enforce granular signing policies (quorum, time windows, transaction limits) per device or fleet. Policies are evaluated and enforced at the HSM layer before any signature is released.

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.
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.
Hardware Security Module (HSM) Integration
We integrate with your chosen HSM vendor (AWS CloudHSM, Azure Dedicated HSM, Thales) to establish a certified Root of Trust. Keys are generated in FIPS 140-2 Level 3+ validated hardware, never exposed in plaintext.
Secure Enclave Provisioning
We implement secure key injection into device secure elements (e.g., TPM, TrustZone, Secure Enclave). Each device receives a unique, non-extractable identity key and an X.509 certificate signed by your private PKI.
Factory & Supply Chain Automation
We automate the provisioning pipeline for your manufacturing line, enabling high-throughput, zero-touch key injection. Each step is cryptographically logged to an immutable ledger for full supply chain auditability.
Onboarding & Lifecycle Management
We deploy a secure onboarding service for devices to authenticate and register with your cloud platform upon first boot. The system manages the full key lifecycle, including revocation and renewal.
Audit & Compliance Reporting
We deliver comprehensive audit logs and compliance reports for every provisioned device, providing proof of process integrity for security audits and regulatory requirements like IoTSF and ETSI.
