FAQ

What is the difference between "digital asset operating system (DAOS)" and "wallet as a service (WaaS)" or "wallet as a protocol (WaaP)"?

The difference is similar to the difference between a database and an operating system. WaaS and WaaP solve one component of digital asset infrastructure: wallets. Whereas DAOS manages the entire lifecycle of digital assets.

Is Vastlink open source?

Open source is part of Vastlink’s intended design, with a long-term goal of a decentralized network. Vastlink is at an early design stage today, so this is a direction rather than a finished production product.

Can we self‑host Vastlink?

That’s the intent. Vastlink is being designed so organizations can run it on their own infrastructure for full control. A production self-hosted release isn’t available yet.

Can we work with Vastlink today?

Yes, through our design-partner program. Vastlink has no production product or pricing yet. Instead, we’re working with a small number of firms in a six-week, no-fee program to shape the custody policy framework and product requirements. You’re under no obligation to buy or continue afterwards. Become a design partner.
