overview
CORE INFRASTRUCTURE

Smart Contract Development

Secure, audited smart contracts built for production by Web3-native engineers.

We architect and deploy custom, gas-optimized smart contracts on EVM and Solana. Our development process is built for security and speed, delivering a production-ready MVP in 2-4 weeks.

  • Full Lifecycle Ownership: From ideation and architecture to deployment, verification, and maintenance.
  • Security-First: Built with OpenZeppelin standards, followed by rigorous internal audits and formal verification tools.
  • Protocol Expertise: ERC-20/721/1155, custom AMMs, lending/borrowing logic, governance systems, and cross-chain bridges.

We don't just write code; we deliver the foundational logic that secures your assets and powers your business model.

Our engineers are battle-tested, having deployed contracts securing over $100M+ in TVL. We provide clear documentation and a comprehensive audit report to ensure your team and stakeholders have full confidence in the system's integrity.

ENTERPRISE-GRADE PRIVACY

Business Outcomes: Secure Data, Protected Value

Our privacy-preserving oracle service delivers more than just data feeds; it provides a foundational layer of trust and confidentiality for your most sensitive on-chain applications. We secure your business logic and protect user value.

04

Confidential Cross-Chain Messaging

Securely transmit private data and proofs between blockchain networks. Our service ensures state and intent remain confidential during cross-chain operations, protecting arbitrage opportunities and user sovereignty.

05

Regulatory-Compliant Data Attestation

Generate cryptographically verifiable attestations for off-chain KYC/AML status or real-world asset data. Serve regulated markets without forcing user data on-chain, balancing compliance with user privacy.

Frequently Asked Questions

Get clear, technical answers to the most common questions about implementing confidential data feeds for your DeFi or Web3 application.

Our service uses a multi-layered architecture combining Trusted Execution Environments (TEEs) like Intel SGX with zero-knowledge proofs (ZKPs). Sensitive data is fetched and signed inside secure enclaves, ensuring the raw data is never exposed to the node operators or the public blockchain. We then deliver verifiable, confidential data points on-chain with cryptographic proofs of correctness and privacy.
