Core Technical Capabilities
We architect and deploy confidential state contracts that enable private on-chain computation, unlocking new use cases in DeFi, identity, and enterprise blockchain. Our development process is built on verifiable security and production-ready reliability.
Zero-Knowledge Circuit Development
Design and implement custom ZK-SNARK/STARK circuits for private state transitions. We use Circom, Halo2, and Noir to prove computations without revealing sensitive inputs, enabling confidential DeFi strategies and identity verification.
FHE-Enabled Smart Contracts
Integrate Fully Homomorphic Encryption (FHE) libraries like Zama's fhEVM to perform computations on encrypted data. Build private voting, sealed-bid auctions, and confidential transaction pools directly on-chain.
Secure Multi-Party Computation (MPC)
Implement threshold signature schemes and distributed key generation for wallet security and cross-chain governance. Our MPC protocols ensure no single party can compromise private keys or sensitive data.
Confidential State Machine Design
Architect application-specific state machines where the state transition logic and data remain private. We define provable state models for compliant financial instruments and private enterprise workflows.
Production Deployment & Orchestration
Deploy confidential contracts with robust proving key management, verifier contracts, and off-chain prover infrastructure. We ensure high availability for proof generation and on-chain verification.

Our Delivery Methodology
We deliver confidential smart contracts through a rigorous, security-first development lifecycle designed for enterprise-grade reliability and rapid deployment.
Architecture & Threat Modeling
We begin with a formal threat model, identifying attack vectors and designing a confidential state architecture using secure enclaves (Intel SGX, AMD SEV) or zero-knowledge proofs (ZK-SNARKs/STARKs).
Secure Development & Auditing
Development in Rust or C++ for enclaves, or Solidity/Cairo for ZK circuits, following OWASP and NIST standards. Every line undergoes internal peer review before external audit.
Continuous Integration & Testing
Automated testing pipelines with unit, integration, and fuzzing tests. We simulate adversarial network conditions and enclave attestation failures to ensure resilience.
Deployment & Runtime Attestation
Managed deployment to your cloud (AWS Nitro, Azure Confidential VMs) or mainnet. We implement remote attestation to verify enclave integrity before any sensitive operation.
Monitoring & Incident Response
Real-time monitoring of enclave health, transaction integrity, and anomaly detection. We provide a dedicated response playbook and 24/7 support for critical issues.
Knowledge Transfer & Maintenance
We deliver comprehensive documentation, operational runbooks, and training for your team. Optional ongoing maintenance agreements with guaranteed response SLAs.
Targeted Applications for Confidential State
Confidential state contracts enable new paradigms in decentralized applications by keeping critical data private on-chain. We build secure, audited solutions for these high-impact scenarios.
Private Voting & Governance
Implement on-chain voting where member ballots and weighted stakes remain confidential until final tally, preventing coercion and front-running. Built with zk-SNARKs or FHE for verifiable privacy.
Client Value: Enable compliant DAO governance and shareholder voting with guaranteed anonymity and cryptographic proof of integrity.
Sealed-Bid Auctions
Develop auction mechanisms where bids are encrypted on-chain, only revealing the winner and price after the auction closes. Eliminates bid sniping and ensures fair market discovery.
Client Value: Launch NFT or DeFi auctions that maximize revenue and participant trust by preventing strategic bidding.
Confidential DeFi Positions
Create lending pools, options, or derivatives where a user's collateral ratio, health factor, or specific position size is hidden from public view, mitigating MEV and predatory trading.
Client Value: Protect institutional and high-net-worth traders from targeted attacks, enabling larger, safer positions in DeFi protocols.
Private Identity & Credentials
Build systems for issuing and verifying verifiable credentials (e.g., KYC status, accreditation) where the claim is proven without revealing underlying personal data, using selective disclosure.
Client Value: Comply with regulations while preserving user privacy, enabling permissioned DeFi pools and gated services without exposing sensitive data.
Hidden Game State & Mechanics
Engineer Web3 games where critical in-game state (e.g., item attributes, random seeds, opponent health) is concealed on-chain, preventing cheating and preserving competitive integrity.
Client Value: Develop provably fair and engaging games that resist botting and exploit, enhancing player trust and retention.
Enterprise Data Collaboration
Facilitate secure multi-party computation (MPC) or federated learning on blockchain, allowing companies to jointly analyze sensitive datasets (e.g., fraud patterns, supply chain data) without sharing raw information.
Client Value: Unlock collaborative insights across corporate boundaries with cryptographic guarantees of data privacy and auditability.
Frequently Asked Questions
Get clear answers on our process, security, timelines, and support for building private, on-chain applications.
A Confidential State Contract (CSC) is a smart contract where the contract's internal state (data) is encrypted and private, while execution logic remains verifiable on-chain. Unlike standard public smart contracts where all data is transparent, CSCs use cryptographic techniques like zero-knowledge proofs (ZKPs) or trusted execution environments (TEEs) to process private inputs and outputs. This enables applications like private voting, confidential DeFi positions, and enterprise-grade supply chain tracking where data privacy is mandatory.
