ENTERPRISE-GRADE INFRASTRUCTURE
Core Registry Capabilities We Deliver
Our KYC Verifiable Credentials Registry is engineered for production. We deliver the foundational infrastructure that scales with your compliance needs, ensuring security, interoperability, and developer velocity.
01
W3C-Compliant Credential Issuance
Issue and manage W3C Verifiable Credentials (VCs) with full DID (Decentralized Identifier) support. Our infrastructure ensures credentials are cryptographically signed, tamper-proof, and instantly verifiable across any compliant ecosystem.

PROVEN METHODOLOGY
Our Development & Integration Process
A structured, security-first approach to deliver a production-ready KYC Verifiable Credentials Registry in 6-8 weeks, minimizing your technical risk and accelerating compliance.
01
Discovery & Architecture Design
We analyze your compliance requirements and user flows to design a custom registry architecture. This includes selecting the optimal credential standard (W3C VC, ERC-5843), issuer/verifier models, and on-chain vs. off-chain data strategies.

02
Smart Contract Development & Auditing
Our team builds the core registry and issuer/verifier contracts in Solidity 0.8+, leveraging OpenZeppelin libraries. All code undergoes internal review followed by a formal security audit from a certified third-party firm before deployment.

KYC Registry Development: Key Questions
Answers to the most common questions CTOs and Product Managers ask when evaluating a KYC Verifiable Credentials registry for their FinTech or Web3 platform.
A production-ready KYC registry with core issuer, holder, and verifier flows typically deploys in 2-4 weeks. Complex integrations with existing IAM systems or custom credential schemas can extend this to 6-8 weeks. We follow a phased delivery model, with a working MVP available for your review within the first 10 business days.
