overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for your specific business logic and audited for deployment.
Every contract undergoes a rigorous security review, combining automated analysis with manual audits to eliminate vulnerabilities before mainnet deployment.
- Custom Logic: Token systems (
ERC-20,ERC-721,ERC-1155), DeFi protocols, DAO governance, and bespoke business rules. - Security-First: Built with
OpenZeppelinstandards, formal verification practices, and multi-signature deployment workflows. - Full Lifecycle: From architecture and development to testing, auditing, deployment, and post-launch monitoring.

Frequently Asked Questions
Get clear answers on our development process, security, timelines, and support for building enterprise-grade MPC wallets.
A standard cross-chain MPC wallet deployment takes 4-6 weeks from kickoff to production. This includes architecture, core development, integration with 2-3 target blockchains, and security audits. Complex requirements like custom governance, multi-sig logic, or support for 5+ chains can extend the timeline to 8-10 weeks. We provide a detailed project plan with weekly milestones.
