Stealth Identity Verification Development | Chainscore Labs

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts to power your protocol.

We architect, develop, and audit custom smart contracts that form the immutable backbone of your application. Our development process ensures gas-optimized code, upgradeable patterns, and comprehensive security from day one.

Full Lifecycle Development: From initial specification and Solidity/Rust coding to deployment on EVM/Solana/Starknet.
Security-First Approach: Adherence to OpenZeppelin standards, formal verification, and pre-audit internal reviews.
Production Focus: Contracts are built for mainnet readiness, including admin controls, pausability, and emergency procedures.

We deliver battle-tested contracts that handle real value, reducing your time-to-audit by 60% and mitigating critical risks before deployment.

Our team specializes in complex logic for:

DeFi: Automated Market Makers (AMMs), lending/borrowing pools, yield aggregators.
NFTs: ERC-721A/1155 with advanced minting, staking, and royalty mechanics.
Enterprise: Custom token standards (ERC-20, ERC-1400), multi-sig governance, and cross-chain bridges.

ARCHITECTURE & SECURITY

Core Technical Capabilities We Deliver

Our stealth identity verification service is built on a foundation of battle-tested cryptographic primitives and enterprise-grade infrastructure, designed to protect user privacy while ensuring regulatory compliance.

Zero-Knowledge Proof Integration

We implement zk-SNARKs and zk-STARKs to enable users to prove identity attributes (e.g., KYC status, age) without revealing the underlying data. This preserves privacy while meeting compliance requirements for DeFi, gaming, and on-chain voting.

Semaphore Protocol Implementation

Deploy anonymous signaling and group membership systems using the Semaphore protocol. Users can prove membership in a verified group (like KYC'd users) and send signals (votes, endorsements) without revealing their identity.

Secure Credential Management

Engineer systems for issuing, storing, and verifying verifiable credentials (VCs) on-chain. We design secure issuer backends and wallet-integrated verifiers using W3C standards, ensuring credentials are tamper-proof and user-controlled.

Custom Privacy-Preserving Circuits

Develop and audit custom zero-knowledge circuits for your specific use case. We optimize for gas efficiency and proof generation speed, whether for custom attestations, reputation scoring, or complex eligibility logic.

Regulatory Gateway & Compliance Layer

Build the off-chain compliance infrastructure that interfaces with traditional KYC providers. We create secure, encrypted APIs that issue privacy-preserving attestations to user wallets, acting as the bridge between Web2 compliance and Web3 privacy.

On-Chain Reputation & Sybil Resistance

Implement systems where anonymous, verified identities can accumulate provable reputation scores or non-transferable tokens (SBTs). This enables sybil-resistant governance and curated communities without sacrificing user anonymity.

DELIVERABLES

Business Outcomes for Your Protocol

Our stealth identity verification service delivers measurable results for your protocol's security, compliance, and user experience. We focus on concrete outcomes, not just features.

Regulatory Compliance Without Friction

Deploy KYC/AML checks that meet global standards (FATF Travel Rule, MiCA) without exposing user identities on-chain. Maintain compliance while preserving user privacy.

Sybil-Resistant Airdrops & Incentives

Distribute tokens and rewards to unique, verified humans. Our zero-knowledge proofs prevent bot farms from draining your treasury, ensuring capital efficiency.

Reduced Legal & Reputational Risk

Mitigate exposure to sanctions violations and illicit finance. Our audit trail provides regulators with necessary proof of compliance upon request, protecting your protocol.

Faster User Onboarding & Retention

Implement a seamless verification flow that takes users seconds, not minutes. Reduce drop-off rates and increase active, legitimate users in your ecosystem.

Stealth Identity Verification

Frequently Asked Questions

Get clear answers about our zero-knowledge identity verification service, from integration to security and pricing.

Our service uses zero-knowledge proofs (ZKPs) to verify user credentials without exposing the underlying data. Users generate a ZK proof from their identity documents (e.g., passport, driver's license) using our SDK. The proof is submitted to your dApp, and our on-chain verifier contract validates it in under 2 seconds. The user's raw data is never stored by us or transmitted to your application, ensuring complete privacy and compliance.
