Architectural Components We Deliver
We build the core infrastructure for self-sovereign KYC, delivering production-ready components that ensure compliance, security, and seamless user onboarding. Each module is designed for integration within 2-4 weeks.
01
On-Chain Identity Registry
Deploy a custom, gas-optimized smart contract registry (ERC-725/ERC-734) to anchor and manage verifiable credentials. Supports zero-knowledge proofs for selective disclosure and integrates with existing KYC providers.

Self-Sovereign KYC: Technical & Compliance FAQs
Technical and regulatory questions our enterprise clients ask before implementing a self-sovereign identity solution.
A complete, production-ready Self-Sovereign KYC (SSI) system with identity storage typically deploys in 4-6 weeks. This includes architecture design, smart contract development, frontend integration, and a full security audit. For a basic MVP with core verification flows, we can deliver in 2-3 weeks. Timelines are fixed-price and guaranteed in our SOW.
