OKX, a leading global fintech company and crypto asset trading platform, has announced the launch of a joint strategic framework in collaboration with asset management firm BlackRock and Standard Chartered Bank. This innovative collaboration aims to integrate the BUIDL digital token—representing investment shares in a BlackRock fund that invests in short-term US Treasury bills—into collateral utilization mechanisms for trading operations. This initiative marks a historic first in financial markets, as a major globally systemic bank assumes the role of custodian in this advanced operational model.

This new framework allows OKX clients to hold their collateral assets with a trusted custodian, operating within a strictly regulated financial custody system entirely independent of the trading platform itself. At the same time, it grants them full flexibility to use these assets as reliable collateral to execute various trades on OKX within an integrated and seamless operational environment, without the need to physically transfer these assets to the platform’s direct accounts.

Innovative custody system for VIPs and institutional clients

Through this carefully designed joint framework, VIP and institutional clients on OKX can allocate the BUIDL token as financial collateral securely stored outside the trading platform. This means assets are not actually deposited within the platform; instead, they are held within a financially regulated custody framework managed by Standard Chartered Bank. This procedure allows institutions to continue trading activities seamlessly via OKX in Middle Eastern and global markets, completely eliminating the need to transfer assets between different platforms and reducing risks associated with transfer operations.

Alongside this strategic option, the platform enables direct depositing and trading of the BUIDL token within the platform environment itself. It can also be deployed as financial collateral that automatically generates yields when used in margin trading operations, enhancing capital management efficiency for traders.

Tokenization of real-world assets

By effectively integrating the BlackRock BUIDL fund token—tokenized on the blockchain network by Securitize, which recently announced a proposed business combination agreement with Cantor Equity Partners, listed on Nasdaq—with the secure and regulated custody services of Standard Chartered Bank, this framework emerges as an exceptional model. This ecosystem is completed by OKX’s advanced infrastructure, specifically designed to execute institutional client transactions and manage trading margins with high professionalism.

This collaboration offers an integrated and unique model where collateral custody and trading operations are executed within a single financial system operating with complete coordination and harmony. This development represents a pivotal step toward cementing the concept of real-world asset tokenization on blockchain networks and directly integrating them into the core infrastructure of global financial markets.

Strategic advantages of the joint framework

This innovative framework offers a set of exclusive advantages that reshape financial trading concepts, most notably:

• Active capital activation: The ability to use the BUIDL token as collateral provides an exceptional opportunity to transform financial margin, long classified in traditional markets as dormant capital outside active investment, into a dynamic asset continuously yielding returns.
• Comprehensive collateral provision: Through this initiative, OKX expands the use of real-world assets by establishing the BUIDL token’s role as a comprehensive and strongly backed financial collateral across the entire platform.
• Enhanced and independent protection: Thanks to the institutional protection provided to the BUIDL token by Standard Chartered Bank, platform clients obtain trading collateral entirely separated from assets deposited on the platform. Clients retain the ability to use them for trading without transferring custody from the bank to the platform, providing an extra layer of protection in rare exchange default scenarios.

Financial leadership vision for the digital future

This collaborative framework, bringing together the world’s largest asset manager, a tier-one global bank, and a leading digital asset exchange, sets a new benchmark for expanding practical use cases within the digital currency ecosystem. It successfully combines the high security standards characteristic of traditional finance with the efficiency and speed typical of open digital markets.

In this context, Samara Cohen, Global Head of Markets Strategy at BlackRock, stated:

“BUIDL was carefully designed to deliver the superior benefits of blockchain tokenization, specifically regarding short-term US Treasury exposure. This innovation enables eligible investors to achieve stable US dollar yields via a blockchain-based technical architecture. This close collaboration with OKX and Standard Chartered opens unprecedented horizons for institutional investors in how they deploy collateral to support and expand their financial operations.”

For his part, Haider Rafique, Global Managing Partner at OKX, emphasized the importance of this step:

“This strategic collaboration highlights the immense potential of real-world asset tokenization on a very large scale. By enabling major institutions to use the BUIDL token as digital collateral across our global platform, we are not only improving capital efficiency but also practically demonstrating how traditional financial instruments can seamlessly integrate into modern digital markets. Real-world asset tokenization aims primarily to make existing financial markets more responsive and transparent, while enhancing accessibility for a broader range of investors.”

Meanwhile, Margaret Harwood-Jones, Global Head of Financing and Securities Services at Standard Chartered Bank, outlined the bank’s role in this ecosystem:

“Our pivotal role as asset custodian in this innovative initiative reflects our steadfast commitment to providing reliable financial solutions to clients alongside the continuous evolution of the integrated financial system. By providing secure custody for the BUIDL token within this unique collateral usage scenario, we directly contribute to enabling clients to seize opportunities in the digital asset world while strictly adhering to the highest standards of protection and regulatory compliance. This collaboration is tangible evidence of traditional financial institutions’ ability to integrate with digital market infrastructure to deliver tokenized assets to investors worldwide in a safe and efficient manner.”

It is worth noting that the launch of this framework did not happen in a vacuum; rather, it is the culmination of intensive testing and extensive technical integration at a high institutional level. The BlackRock BUIDL token is issued on a public blockchain network, representing real shares of a fund investing its assets in cash, US Treasury bills, and repurchase agreements, while ensuring yield distribution transparently across the blockchain. Its seamless and innovative integration with OKX’s collateral framework is definitive proof that real-world tokenized assets can be used on a wide and influential scale within operational frameworks adopted by major institutions in trading, margin management, and liquidity provision.

Frequently asked questions

What is the BUIDL token and how is it used?

It is a digital token representing shares in a BlackRock investment fund that invests in short-term US Treasury bills. It can be used as financial collateral to execute trades on OKX while remaining under the custody of Standard Chartered Bank.

What is the benefit of using collateral assets outside the trading platform?

This model provides enhanced protection for investors and institutions, as assets remain held with an independent, regulated custodian such as Standard Chartered Bank, minimizing risks related to asset transfers and providing extra security in the event of an exchange default.

How does this framework contribute to activating dormant capital?

By using this token as collateral, margin—which is typically considered dormant capital generating no profits in traditional systems—is transformed into an active investment asset that yields automatic returns for investors while deployed in margin trading operations.
