Privacy-Preserving KYC Mobile App Development

We design and develop mobile applications that utilize decentralized identifiers (DIDs), verifiable credentials, and selective disclosure to minimize data exposure during mandatory compliance checks.

overview
FOUNDATION

Blockchain Infrastructure Development

Build scalable, secure, and production-ready blockchain backends tailored to your application.

We architect and deploy the foundational infrastructure your Web3 product needs to launch and scale. Our solutions are built for 99.9% uptime, sub-second finality, and enterprise-grade security from day one.

  • Node Infrastructure: Managed EVM (Ethereum, Polygon, Arbitrum) and non-EVM (Solana, Cosmos) RPC nodes with load balancing and failover.
  • Indexing & Data: Custom subgraphs (The Graph) and indexers for real-time, queryable on-chain data.
  • Security First: Implementation of OpenZeppelin standards, multi-sig wallet setups, and comprehensive audit preparation.
  • DevOps & Monitoring: Automated CI/CD pipelines, containerized deployments, and 24/7 performance dashboards.

We deliver a fully managed backend, allowing your team to focus on core product logic and user experience, reducing your time-to-market by weeks.

ENGINEERED FOR COMPLIANCE & SCALE

Core Technical Capabilities

Our privacy-preserving KYC mobile app is built on a foundation of enterprise-grade blockchain infrastructure, delivering secure identity verification without compromising user data or regulatory compliance.

01

Zero-Knowledge Proof Identity

Implement ZK-SNARKs and ZK-STARKs to verify user credentials without exposing raw PII. Users prove they are over 18 or accredited without revealing their birthdate or income.

On-Chain Attestation Registry

Issue and manage soulbound token (SBT) attestations for verified identities. Built on ERC-4973/ERC-7231 standards for portable, non-transferable credentials across DeFi and dApps.

PROVEN METHODOLOGY

Our Development & Integration Process

A structured, four-phase approach designed to deliver a secure, compliant, and user-friendly privacy-preserving KYC mobile app, from initial design to seamless mainnet deployment.

01

Architecture & Compliance Design

We define the zero-knowledge proof (ZKP) architecture and data flow to ensure regulatory compliance (GDPR, CCPA) by design. This phase establishes the cryptographic foundation for selective disclosure and data minimization.
