USD Vault
An institutional, non-custodial USD vault for digital asset platforms
The Platform
Vault Overview
The USD Vault is non-custodial. The partner platform or its user keeps custody of the assets, and capital is deployed through the vault's smart contracts across strategies and supported blockchains.
It is platform infrastructure, not a registered fund, and no rate or term is promised: what a partner earns depends on the underlying strategies and venues, and capital is exposed to smart-contract, protocol, stablecoin and liquidity risk, including loss of principal.
The USD Vault is not available to U.S. clients.
Capabilities
Key Features
Scalable Infrastructure
Built to run strategies across multiple chains — expand to new chains without rebuilding.
Multiple Partner Support
Multiple partners operate within the same vault for efficient capital deployment.
Multi-Chain Asset Onboarding
Accept assets from multiple blockchains for flexible partner funding.
Rapid Chain Deployment
Deploy quickly to emerging chains as they launch.
Architecture
How the vault puts capital to work
Partner platforms and institutional allocators transfer capital into the vault, and yield returns along the same path.
Capital flow
Supported chains and venues vary by partner and jurisdiction. Illustrative. Strategy mix varies by product and market conditions.
Mandate
The allocation moves. The mandate does not.
Before capital is deployed, the scope it will be allocated within is written down: which strategies are eligible, which venues may be used, and the limits that govern exposure.
Mandate terms are agreed with each partner during scoping and vary by partner and jurisdiction. Nothing on this page describes what capital allocated under a mandate will earn.
Venues
Where capital is allocated
The vault currently allocates capital to the venues below. The set is subject to change.
- Y10K
Venues are listed alphabetically; order and size say nothing about the amount allocated. Each venue carries its own risks.
Digital asset strategies carry substantial risk, including the loss of all capital deployed. Risks include smart-contract failure and exploits, failure or governance changes at a venue or protocol, oracle failure, bridge failure, stablecoin de-pegging, default or custody failure at an issuer or counterparty underlying a venue, price volatility, and liquidity constraints that can delay or limit withdrawals, especially in stress. A non-custodial structure does not remove these risks or assure any outcome. No rate, term or level of earnings is promised.

Implementation
Vault Integration
API-based integration with technical documentation and integration support from our team. Asset support today is focused on USD stablecoins.
We support scoping, integration, and launch — from first technical review to go-live.
- USD Vault availability, supported chains, and terms vary by jurisdiction and partner type.
- The vault infrastructure itself does not perform end-user identity verification. Each partner runs the identity, anti-money-laundering, and eligibility checks its own obligations require, for its own users.
- Vault technical documentation is hosted on PrimeYield at primeyield.io/developers.
Vault infrastructure is a technology platform offered to institutional integration partners. It is not a fund, deposit, or other regulated investment product, and no statement on this page describes a regulated offering. Availability of vault strategies, supported networks, and supported assets varies by partner and jurisdiction, and certain strategies are not available to U.S. persons or in other jurisdictions where they would be unlawful. Each partner is responsible for determining how, where, and to whom any product built on this infrastructure is offered, and for its own regulatory and disclosure obligations.
