JPMorgan Chase has completed its first settlement of tokenized U.S. Treasuries on a public blockchain, in partnership with Chainlink and Ondo Finance. The transaction used JPMorgan's Kinexys platform for payment settlement on a private blockchain and Ondo Chain for the tokenized asset leg on a public blockchain, involving Ondo's Short-Term U.S. Government Treasuries Fund (OUSG). The cross-chain Delivery versus Payment (DvP) transaction was enabled by the Chainlink Runtime Environment, which securely coordinated between the private Kinexys network and the public Ondo Chain. Colin Cunningham of Chainlink Labs stated, "This is the first time a major global bank has connected its core payment systems to a public blockchain." JPMorgan's Kinexys platform processes about $2 billion daily and has managed $1.5 trillion in derivatives contracts. The experiment demonstrates institutional interest in real-world asset tokenization, a sector now exceeding $12 billion in total value locked. Chainlink co-founder Sergey Nazarov described the transaction as an example of TradFi and DeFi convergence. Nathan Allman of Ondo Finance emphasized the deal's significance for compliant blockchain infrastructure in managing real-world assets at scale.
