PROVEN METHODOLOGY
Our Development & Integration Process
A structured, four-phase approach to deliver a production-ready, secure, and scalable EVM IoT Device DID Framework, minimizing your time-to-market and technical risk.
01
Architecture & Protocol Design
We design the DID method specification and smart contract architecture, selecting optimal standards (ERC-1056, ERC-734/735) for your IoT ecosystem. This phase establishes the foundation for secure, interoperable device identity.
2-3 weeks

EVM IoT DID Framework: Key Questions
Common questions from CTOs and product leads evaluating a custom Decentralized Identity framework for IoT devices on EVM chains.
A standard EVM IoT DID framework deployment takes 2-4 weeks from kickoff to mainnet launch. This includes smart contract development, integration with your device firmware, and a full security audit. Complex ecosystems with 10,000+ device types may extend to 6-8 weeks. We provide a detailed sprint-by-sprint Gantt chart during scoping.
