Crypto wallet FAQs.
Custodial or non-custodial?
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.
