OKX has incorporated BlackRock's BUIDL tokenized US Treasury fund into its collateral framework in collaboration with Standard Chartered. This integration allows eligible institutional and VIP clients to use the yield-bearing BUIDL as trading collateral while ensuring assets remain in regulated custody. This move represents a significant step towards bringing real-world assets onchain, with OKX MENA and CIS CEO Rifad M stating that more assets will become accessible for users in the future.
