ENTERPRISE-READY COMPONENTS
Core SSI Module Capabilities We Deploy
We architect and deploy production-grade Self-Sovereign Identity modules for your AppChain, delivering verifiable credentials, decentralized identifiers, and secure key management as a managed service.
04
Credential Schema & Policy Engine
Define and enforce credential schemas on-chain. Our policy engine allows issuers to set governance rules for credential issuance and verification, ensuring compliance and interoperability across your ecosystem.
05
Interoperability Bridges & Standards
Ensure your SSI module works across ecosystems. We implement IANA-registered DID methods, support for well-known DID configurations, and bridges to major networks like Ethereum, Polygon, and Solana for cross-chain identity proofs.
06
Audited Smart Contract Suite
Receive a fully audited suite of SSI smart contracts, including the DID registry, VC status registry, and governance modules. Our code undergoes rigorous security reviews following OpenZeppelin standards.

PREDICTABLE TIMELINE
Our 4-Week Deployment Process
A structured, milestone-driven approach to deliver your production-ready Self-Sovereign Identity module on time, every time.
01
Week 1: Architecture & DID Method Design
We define your core identity architecture, select the optimal DID method (did:ethr, did:key, did:web), and design the credential schemas for your specific use case (KYC, credentials, access control).

Technical & Commercial Details
AppChain SSI Deployment: Frequently Asked Questions
Get clear answers on timelines, costs, and technical specifics for deploying a Self-Sovereign Identity (SSI) module on your application-specific blockchain.
Standard deployment for a core SSI module with verifiable credentials and basic DID management takes 2-4 weeks from kickoff to mainnet launch. Complex integrations (e.g., custom credential schemas, cross-chain attestations, or advanced revocation mechanisms) can extend this to 6-8 weeks. Our agile delivery process includes weekly sprints and demos.
