overview
CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production at scale.
- End-to-End Development: From specification and gas optimization to deployment and on-chain verification.
- Formal Verification & Audits: Code undergoes rigorous internal review and can be prepared for third-party audits from firms like
ConsenSys Diligence. - Production-Ready Code: Contracts are built for upgradability, pausability, and integration with frontends and oracles.
We deliver contracts you can trust, reducing time-to-audit by 40% and mitigating critical vulnerabilities before deployment.

Frequently Asked Questions
Get clear answers on timelines, security, and process for building a secure ZK-Rollup bridge to Bitcoin.
A production-ready bridge MVP typically takes 4-6 weeks from kickoff to mainnet deployment. This includes 1 week for architecture design, 2-3 weeks for core smart contract and ZK-circuit development, and 1-2 weeks for integration, testing, and security review. Complex multi-asset bridges or custom economic models may extend to 8-10 weeks. We provide a detailed sprint-by-sprint roadmap after the initial technical discovery.
