Privacy-First Public Surveillance Systems

We build secure, on-chain data pipelines for public safety and traffic cameras. Our Layer 3 solutions use zero-knowledge proofs to enable encrypted, anonymized data analysis while preserving citizen privacy and meeting GDPR/CCPA mandates.

overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect, develop, and audit custom Solidity/Rust smart contracts that form the backbone of your protocol. Our focus is on security-first development, leveraging battle-tested patterns from OpenZeppelin and rigorous internal audits to mitigate risk before deployment.

  • Token Standards: Custom ERC-20, ERC-721, ERC-1155, and ERC-4626 vaults.
  • DeFi Primitives: Automated Market Makers (AMMs), lending pools, staking mechanisms, and yield optimizers.
  • Governance Systems: DAO frameworks with transparent proposal and voting modules.
  • Enterprise Logic: Custom business logic for asset tokenization, supply chain, and verifiable credentials.

We deliver gas-optimized, upgradeable contracts with comprehensive test coverage, ensuring faster mainnet deployment and long-term maintainability.

PROVEN FRAMEWORK

Our Delivery Methodology

A structured, four-phase approach that ensures your privacy-first surveillance system is delivered on time, within budget, and with enterprise-grade security.

01

Architecture & Threat Modeling

We begin with a Zero-Trust design review, mapping data flows and identifying potential attack vectors. This phase establishes the cryptographic foundations (zk-SNARKs, MPC) and on/off-chain architecture to ensure privacy by design.

1-2 weeks

02

Secure Development & Auditing

Our team builds the core surveillance logic and privacy-preserving protocols using Solidity, Rust, or Go. Every module undergoes internal peer review and automated testing before submission to a top-tier security firm for a formal audit.

Custom Smart Contract Development

Secure, production-ready smart contracts built by experts for your Web3 product.

We architect and deploy custom smart contracts that form the secure, immutable core of your application. Our development process is built on Solidity 0.8+ and OpenZeppelin security patterns, ensuring your logic is robust and upgradeable from day one.

Deliver a secure, auditable, and gas-optimized foundation for your token, DeFi protocol, or NFT platform.

  • Token Standards: Full-suite development for ERC-20, ERC-721, ERC-1155, and custom multi-token economies.
  • DeFi & DAOs: Automated Market Makers (AMMs), staking pools, governance modules, and yield aggregators.
  • Security-First Process: Includes formal verification methods and preparation for third-party audits by firms like CertiK or Quantstamp.
  • Measurable Outcome: Go from spec to a fully tested, deployable contract suite in as little as 2-4 weeks.

Frequently Asked Questions

Get clear answers on our process, security, and deployment for public surveillance systems that protect privacy by design.

Our systems are built on zero-knowledge cryptography and on-chain attestations. Video feeds are processed locally at the edge; only anonymized metadata (e.g., "vehicle detected") and cryptographic proofs are transmitted. Raw biometric data is never stored centrally, ensuring compliance with GDPR and similar frameworks. We implement privacy by design, not as an add-on.
