ZK-Proof Identity Attestation Services
We design and build custom, privacy-preserving identity verification systems using zero-knowledge proofs. Our solutions enable full regulatory compliance for DeFi, gaming, and enterprise applications on ZK-rollups like StarkNet and zkSync, without storing or exposing user PII on-chain.

PROVEN METHODOLOGY
Our Development & Integration Process
A structured, four-phase approach to deliver production-ready ZK identity attestation systems. We focus on security, interoperability, and rapid deployment to accelerate your time-to-market.
01
Discovery & Architecture Design
We analyze your use case to design a custom ZK attestation architecture. This includes selecting optimal proving systems (e.g., Circom, Halo2), defining credential schemas (W3C VC), and planning integration with your existing auth stack.
1-2 weeks
Design Phase

Requirement Alignment
02
Circuit Development & Security Audit
Our team builds and rigorously tests the core ZK circuits and smart contracts. Every component undergoes internal review followed by a formal audit from a leading security firm like Trail of Bits or Spearbit before deployment.
