At River, our mission is to connect every asset to its opportunity.
With our chain-abstraction stablecoin system, satUSD has already become a shared currency across ecosystems, backed by over $700M in assets.
As more institutions explore on-chain yield, they ask the same question:
How can we participate with full security and compliance?
This is why we built Prime Vault.
What is Prime Vault
Prime Vault works in a way that feels familiar to Smart Vault users:
- Deposit assets
- The system auto-converts into satUSD and channels it into yield
- Users receive periodic returns
The difference is in security standards designed for institutions:
- Custodian Protection: Assets remain with leading custodians under regulation and insurance coverage
- Zero Liquidation Risk: Automated management ensures stability even in volatile markets
- Transparent Yield: Generated from satUSD staking pools and yield strategy, not unsustainable subsidies.
Today, more than $250M in assets have already been deposited into Prime Vault, underscoring the strong demand from institutional participants.
How Does Prime Vault Work?
Prime Vault connects institutional-grade security with sustainable yield access.
Institutions can deposit assets into the system, automatically mint & stake satUSD, access yield opportunities with custodian wallet.
This enables institutions to earn passive returns while their capital stays protected by top-tier custodians and a zero-liquidation mechanism.
