Ondo Finance has partnered with BlackRock and Securitize to submit its OUSG token to the Spark Tokenization Grand Prix, an initiative by the Sky ecosystem aiming to integrate $1 billion in tokenized financial assets.

The OUSG token currently supports daily subscriptions and redemptions of up to $25 million, with plans to increase this capacity to $50 million by the end of the year. The asset currently holds over $600 million in total value locked.

The proposal features a liquidity facility backed by BlackRock, Securitize, and Circle. Ondo aims to incorporate additional liquidity facilities and stablecoin pairs, such as USDS, to enhance the ecosystem's RWA holdings and onchain liquidity.

If both OUSG and BUIDL are integrated into the Sky ecosystem, the platform could convert OUSG into BUIDL to rebalance its portfolio. Additionally, Ondo's Global Market initiative is intended to broaden the range of fixed-income products available to Sky.
