overview

CORE INFRASTRUCTURE

Smart Contract Development

Secure, gas-optimized smart contracts built by Web3-native engineers.

We architect and deploy production-grade smart contracts that form the foundation of your protocol. Our development process is built on audited security patterns and gas optimization from day one, ensuring your application is both secure and cost-effective for users.

Custom Logic: ERC-20, ERC-721, ERC-1155, and bespoke token standards.
DeFi Primitives: Automated Market Makers (AMMs), lending pools, staking vaults.
Security First: Development with OpenZeppelin libraries and pre-audit internal reviews.
Full Lifecycle: From specification and development to deployment and mainnet verification.

We deliver battle-tested contracts that reduce audit cycles by 40% and minimize on-chain operational costs.

BUILDING BLOCKS FOR SECURE DATA

Core Architectural Components We Deliver

We architect and implement the foundational cryptographic and database layers that enable your application to process sensitive data on-chain without exposing it. Each component is built to enterprise-grade security and performance standards.

Zero-Knowledge Proof Circuits

Custom ZK-SNARK and ZK-STARK circuits for verifying computations on encrypted data. We implement circuits for specific business logic, ensuring privacy while maintaining on-chain verifiability.

Fully Homomorphic Encryption (FHE) Integration

Integration of FHE libraries (e.g., OpenFHE, Microsoft SEAL) to enable computations on encrypted data. We handle the complex key management and performance optimization required for practical use.

Secure Multi-Party Computation (MPC) Nodes

Deployment of decentralized MPC node networks for threshold cryptography. Our architecture ensures no single party can reconstruct private keys or decrypt sensitive data, enabling secure wallet operations and key management.

Threshold Models

Byzantine Fault Tolerant

Network Consensus

Encrypted State Management

On-chain storage of encrypted data blobs with efficient retrieval proofs. We design systems using verifiable encryption and Merkle proofs to ensure data integrity and availability without revealing plaintext.

Privacy-Preserving Oracles

Custom oracle design that fetches and delivers off-chain data in an encrypted format. These orcles enable smart contracts to act on private real-world data, a critical component for compliant DeFi and enterprise applications.

Audit & Compliance Layer

Built-in mechanisms for generating zero-knowledge proofs of regulatory compliance (e.g., proof of KYC status, transaction sanctions screening) without exposing user identities or sensitive data.

ENTERPRISE-GRADE SECURITY

Proven Cryptographic Libraries & Protocols

We build your encrypted database on battle-tested, open-source cryptographic primitives and protocols, eliminating the risk of custom cryptographic implementations. This ensures your data privacy architecture is secure by design and future-proof.

Zero-Knowledge Proofs (ZKPs)

Implement zk-SNARKs (via Circom/SnarkJS) and zk-STARKs for selective data verification without exposing underlying information. Enables private transactions, identity proofs, and compliance checks.

Fully Homomorphic Encryption (FHE)

Deploy TFHE and CKKS schemes using libraries like OpenFHE and Concrete. Perform computations (search, analytics) directly on encrypted data, ensuring end-to-end privacy.

Multi-Party Computation (MPC)

Integrate MPC protocols for secure key management and threshold signatures. Distributes trust across multiple parties, preventing single points of failure for sensitive operations.

Authenticated Encryption

Utilize AES-256-GCM and ChaCha20-Poly1305 for data-at-rest and in-transit encryption. Provides confidentiality, integrity, and authenticity guarantees for all stored records.

Post-Quantum Cryptography (PQC)

Future-proof your architecture with NIST-standardized algorithms like Kyber (KEM) and Dilithium (signatures). Protects against threats from quantum computers.

Audited & Open-Source Foundations

All cryptographic components are built on libraries with public security audits (e.g., by Trail of Bits, NCC Group) and active community maintenance, ensuring transparency and reliability.
