Frequently Asked Questions
Get clear answers on how we secure your streaming platform's assets with enterprise-grade hardware wallet integration.
Standard integrations take 3-5 weeks from kickoff to production deployment. This includes architecture design, smart contract development, secure key management setup, and comprehensive testing. Complex multi-chain or custom signing logic can extend this to 6-8 weeks. We provide a detailed project plan with milestones during the initial scoping call.

SECURE FOUNDATIONS
Custom Smart Contract Development
Production-ready smart contracts built for security, scalability, and compliance.
We architect and deploy custom Solidity and Rust smart contracts that form the core logic of your dApp. Every contract undergoes a rigorous security-first development lifecycle, from design to audit.
- End-to-End Development: Token standards (
ERC-20,ERC-721,ERC-1155), DeFi protocols (AMMs, lending/borrowing), DAOs, and bespoke business logic. - Security as Standard: Built with
OpenZeppelinlibraries, automated testing (Hardhat/Foundry), and formal verification. Includes a pre-audit review before submission to top firms. - Gas Optimization: Expert-level tuning to reduce deployment and transaction costs by up to 40%, ensuring economic viability.
We deliver audited, production-grade contracts in 2-4 weeks, giving you a secure and efficient foundation to build upon.
