Ondo Finance said in a post on the X platform that it has joined forces with BlackRock and Securitize to submit a proposal to introduce Ondo short-term US Treasury OUSG to Sky's (formerly MakerDAO) Spark Tokenization Contest. OUSG is an on-chain financial product that provides consistent returns with short-term US Treasury bonds, with an asset management scale of about 229 million US dollars. Ondo hopes that OUSG can become an effective support for the Sky stablecoin USDS and enhance the yield and liquidity of the Sky ecosystem.
