CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
We deliver contracts that are secure by design, not by audit alone.
- Custom Logic: Build
ERC-20,ERC-721,ERC-1155, and bespoke protocols for DeFi, NFTs, or DAOs. - Security & Audits: Development with
OpenZeppelinstandards, followed by internal review and preparation for third-party audits. - Full Lifecycle: From specification and development to deployment, verification, and ongoing maintenance support.

Technical & Commercial Insights
Credential Revocation Registry FAQs
Answers to the most common questions CTOs and technical founders ask when evaluating a partner for building a secure, production-ready revocation registry.
A standard, production-ready revocation registry for a single blockchain (e.g., Ethereum, Polygon) typically deploys in 2-4 weeks. This includes smart contract development, integration with your existing identity framework, and initial testing. Complex multi-chain deployments or integration with proprietary SSI ecosystems can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones during the initial scoping call.
