PROVEN METHODOLOGY
Our Development & Integration Process
A structured, security-first approach to deliver a production-ready identity layer in weeks, not months. We handle the technical complexity so you can focus on your core product.
01
Architecture & Protocol Design
We design a custom, scalable identity schema and select the optimal protocols (e.g., ERC-725, Verifiable Credentials, EIP-4361) for your specific cross-chain use case, ensuring interoperability and future-proofing.

Technical & Commercial Details
Cross-Chain Identity Aggregator FAQs
Get clear, specific answers to the most common questions from CTOs and technical founders evaluating identity solutions.
For a standard deployment targeting 2-3 major chains (e.g., Ethereum, Polygon, Arbitrum), the typical timeline is 4-6 weeks from kickoff to mainnet launch. This includes architecture design, smart contract development, integration with your dApp, security audit, and deployment. Complex multi-chain ecosystems or novel verification logic can extend this to 8-10 weeks. We provide a detailed, phase-gated project plan at the start.
