IoT Device Governance & Multi-Sig Control

Implement flexible M-of-N approval workflows for critical device actions like firmware updates, configuration changes, and access control. Eliminate single points of failure and enforce corporate governance policies directly on-chain.

Define and automate governance rules as executable smart contracts. Enforce compliance, automate routine operations, and create tamper-proof audit trails for all device interactions and administrative actions.

Verify device identity and state integrity through cryptographic proofs. Ensure only authorized, compliant hardware can join the network or execute commands, preventing unauthorized or compromised device access.

Assign role-based access control (RBAC) for device management. Define distinct permissions for operators, auditors, and administrators, ensuring least-privilege access across your entire IoT estate.

Every governance action—from a policy change to a firmware signature—is recorded on a immutable ledger. Streamline regulatory compliance (GDPR, HIPAA) and internal audits with a single source of truth.

Future-proof your governance with a modular design. Seamlessly upgrade individual components—like the voting mechanism or oracle feeds—without disrupting device operations or requiring a full migration.

We design a resilient, multi-layered security architecture for your IoT fleet. This includes defining device roles, permission hierarchies, and attack surface analysis to preempt vulnerabilities before a single line of code is written.

Development of custom, auditable multi-signature control contracts (e.g., Safe{Wallet} modules, Zodiac) and device attestation logic. Built with Solidity 0.8+ and OpenZeppelin libraries for maximum security.

Secure integration of hardware security modules (HSM/TEE) and IoT device SDKs with the blockchain layer. We implement secure key management, signed payload generation, and real-time state verification.

Every component undergoes rigorous internal review followed by external audits from partners like Spearbit or Code4rena. We conduct penetration testing on the full stack, from device firmware to smart contracts.

We deploy the complete system to a private testnet or staging environment that mirrors production. This phase includes load testing, failure scenario simulations, and multi-sig governance dry-runs with your team.

Managed deployment to your chosen mainnet (Ethereum, Polygon, Arbitrum) with comprehensive documentation and operational runbooks. We provide training for your team on system administration and incident response.
