BlackRock BUIDL Fund Now Accepted as OKX Trading Collateral

OKX has integrated BlackRock's BUIDL tokenized U.S. Treasury fund into its collateral framework, enabling institutional and VIP clients to utilize the yield-bearing asset as trading margin. This development allows eligible users to post BUIDL as collateral while it remains under the custody of Standard Chartered, marking the first off-exchange tokenized collateral framework backed by a globally systemically important bank. Within the OKX margin system, BUIDL is treated as fungible with USD and USDC, ensuring that clients maintain ownership and continue to accrue yield while actively trading. This initiative, currently live for clients of OKX Middle East, represents a significant evolution in the utility of tokenized real-world assets. By moving beyond passive holding, the integration demonstrates how tokenized products can function as active market infrastructure within live trading environments. The collaboration builds upon an existing collateral mirroring program between OKX and Standard Chartered, signaling a broader industry shift toward deeper institutional adoption of RWA-backed financial instruments. Future expansion of this framework is planned based on regional demand and jurisdictional requirements.
