Frequently Asked Questions
Common questions from CTOs and technical leads about integrating institutional-grade blockchain access.
A standard integration takes 2-4 weeks from kickoff to production. This includes architecture review, smart contract deployment, multi-sig configuration, and final security audit. Complex requirements like custom RPC extensions or cross-chain bridges can extend this to 6-8 weeks. We provide a detailed project plan within the first 3 days of engagement.
