CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Security-First Development: Code built on
Solidity 0.8+withOpenZeppelinlibraries and formal verification patterns. - Full-Stack Integration: Contracts are designed to work seamlessly with your frontend, backend, and
ERC-20/ERC-721tokens. - Comprehensive Audits: Every contract undergoes internal review and is prepared for third-party audits from firms like CertiK or Quantstamp.
We don't just write code; we deliver the immutable business logic that powers your protocol's trust, security, and revenue.

Sovereign Rollup Data Availability
Frequently Asked Questions
Get clear answers on how our dedicated oracle data availability service integrates with your sovereign rollup to ensure secure, reliable, and cost-effective operations.
We provide a dedicated, high-availability data availability (DA) layer specifically for oracle networks operating on sovereign rollups. The service publishes and secures oracle data (price feeds, randomness, etc.) off-chain, making it verifiably available for your rollup's sequencer to pull on-demand. This eliminates the need to post all oracle data directly to a costly settlement layer like Ethereum, reducing your operational costs by 60-90% while maintaining cryptographic guarantees of data integrity and liveness.
