Both. The right model depends on your product, users and regulatory position, which we assess during discovery. ### Have you built custody before? Yes. Custody was part of the centralized exchange we delivered in 20 weeks, which has held 99.9% uptime since launch. ### Which chains do you work with? We choose per use case after comparing chains, custody and infrastructure options. Our smart contract work has shipped across multiple chains. ### How long does a Web3 build take? It depends on scope. For reference, we delivered a centralized exchange in 20 weeks and stablecoin payment rails in 5. We agree milestones up front. ## Ready to turn your vision into reality?
