According to online reports, according to Fortune, JPMorgan Chase completed the settlement transaction of tokenized U.S. Treasury bonds for the first time through public blockchain on May 14, marking its move from a "walled garden" private chain to an important step towards opening up the blockchain ecosystem. The transaction is provided by Ondo Finance with tokenized treasury bonds and is achieved through the oracle service provided by Chainlink. Previously, JPMorgan Chase's digital asset operations were mostly carried out on its private chain Onyx, and this transaction shows its strategy shifts to a more open financial infrastructure.
