BounceBit, OKX and Standard Chartered Expand Institutional Access to Tokenized U.S. Treasury Yield Strategies via Collateral Mirroring Program

Today we announce a collaboration with Standard Chartered and OKX.

Prime’s tokenized Treasury CeDeFi strategies now pair custody at a G-SIB with off-exchange settlement and execution on OKX. The result is practical tokenization that fits existing workflows and scales.

What’s live

Prime sources regulated tokenized cash equivalents from Franklin Templeton’s Benji and BlackRock’s BUIDL via Securitize. Assets remain in custody at Standard Chartered and mirror to OKX for execution. Institutions retain legal ownership, receive audit-ready reporting, and gain 24/7 collateral mobility.

How it works

The architecture separates where assets are held from where they are used:

• Bank custody: Segregation and governance at Standard Chartered

• Execution and liquidity: Off-exchange settlement and trading on OKX

• Collateral mirroring: Real-time movement of collateral without transferring assets onto an exchange

This reduces venue risk, improves capital use, and enables programmatic controls that traditional rails struggle to deliver.

Why it matters

Tokenized Treasuries can now operate at production scale with clear ownership, continuous liquidity access, and reporting suitable for institutional treasuries. This is a concrete step toward funds and fixed income operating natively onchain.

What’s next

Prime will expand into broader RWA access and structured yield strategies designed for institutions. If your mandate is yield with control and transparency, we’re ready to engage.
