PROVEN METHODOLOGY
Our Development & Integration Process
A streamlined, security-first approach to integrate privacy-preserving verification into your platform, minimizing disruption and maximizing trust.
01
Discovery & Architecture Design
We analyze your user flow and compliance requirements to design a custom verification architecture. We select the optimal zero-knowledge proof (ZKP) framework (e.g., Circom, Noir) and define the on-chain/off-chain data model.
1-2 weeks
Design Phase

Requirement Mapping
02
Circuit Development & Auditing
Our cryptographers develop and optimize the core ZK circuits for credential verification. Every circuit undergoes peer review and formal verification before proceeding to a full security audit with partners like Veridise or OtterSec.
2-4 weeks

Security Audit
03
Smart Contract & API Integration
We deploy the verifier contracts (e.g., on Ethereum, Polygon, Base) and build a robust, rate-limited API gateway. This provides a simple endpoint for your frontend to submit proofs and receive verification status.

Privacy-Preserving Creator Verification
Frequently Asked Questions
Get clear answers on how we build secure, anonymous verification systems for digital creators and marketplaces.
Our systems use zero-knowledge proofs (ZKPs) to verify creator credentials without exposing sensitive personal data. A creator proves they are a real human, meet specific platform criteria (like follower counts or KYC status), and own their social accounts—all without revealing the underlying data. The output is a verifiable, anonymous credential (like a Soulbound Token) that platforms can trust. We typically implement this using Circom for circuit design and SnarkJS for proof generation, integrated with your existing user onboarding flow.
