CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Custom Tokenomics: Design and implement
ERC-20,ERC-721, andSPLtokens with vesting, minting controls, and tax mechanisms. - DeFi & dApp Logic: Build automated market makers (AMMs), staking pools, NFT marketplaces, and governance systems.
- Enterprise Integration: Create compliant contracts for real-world assets (RWA), supply chain, and institutional finance.
We deliver battle-tested code with a 99.9% uptime SLA and a typical MVP delivery timeline of 2-3 weeks.
Every contract undergoes rigorous unit testing and a pre-deployment security review, ensuring your protocol launches with confidence.

PROVEN FRAMEWORK
Our Delivery Methodology
We deliver production-ready, secure oracles for confidential L2s through a structured, collaborative process that minimizes your time-to-market and technical risk.
01
Architecture & Design Review
We analyze your confidential L2's architecture (Aztec, Polygon Miden, etc.) to design a custom oracle solution. This includes defining data requirements, attestation models, and integration points for optimal performance and security.
1-2 weeks

Privacy-Preserving Oracle for Confidential L2s
Frequently Asked Questions
Get clear answers on how our confidential oracle service works, from integration to security and support.
We use a multi-layered privacy architecture: Trusted Execution Environments (TEEs) for secure off-chain computation, zero-knowledge proofs (ZKPs) for verifiable data integrity, and end-to-end encryption for data in transit. This ensures price feeds, randomness, and other data are never exposed in plaintext on-chain or during processing, meeting the strict privacy requirements of Aztec, Aleo, and other confidential L2s.
