CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production on EVM, Solana, and Cosmos chains.
We architect and deploy mission-critical smart contracts with a focus on security, gas efficiency, and upgradability. Our contracts are the foundation for your protocol's logic, assets, and user trust.
- Production-Ready Code: Built with
Solidity 0.8+,Rust, orCosmWasmusing established patterns from OpenZeppelin and Anchor. - Security-First Development: Every line undergoes internal review against common vulnerabilities (reentrancy, overflow, access control) before formal audit.
- Clear Deliverables: Fully documented source code, deployment scripts, and a comprehensive audit report from a top-tier firm.
We deliver contracts you can deploy with confidence, reducing time-to-market and mitigating existential risk.

L2 DA Surveillance FAQs
Get clear answers on how our L2 Data Availability Layer Surveillance service works, its security, and what it delivers for your protocol.
Our system provides 24/7 surveillance of your Layer 2's Data Availability (DA) layer, specifically tracking: sequencer liveness, data submission latency to L1, blob or calldata availability, state root commitments, and fraud proof/validity proof generation windows. We alert you to any deviation from your defined SLAs, such as data being withheld for >15 minutes or sequencer downtime exceeding your tolerance.
