BUILT FOR IOT
Core Smart Contract Capabilities
We architect and deploy secure, gas-efficient smart contracts that form the trustless backbone of your IoT access network, enabling automated device management and verifiable transactions.
01
Device Identity & Access Control
Implement ERC-721/ERC-1155-based device NFTs for unique, on-chain identities. Integrate role-based access control (RBAC) using OpenZeppelin's AccessControl to manage permissions for device registration, activation, and decommissioning.

02
Automated Micro-Payments & Billing
Develop custom payment channels or integrate with Layer-2 solutions for high-frequency, low-cost micro-transactions. Deploy automated escrow contracts for pay-per-use or subscription-based IoT service models.
