DBS Bank of Singapore and JPMorgan's Kinexys are jointly developing a framework for tokenized deposit interoperability. This initiative aims to enable 24-hour cross-chain transfers and settlements between public and permissioned blockchains. The framework will facilitate interaction between the JPM Deposit Token, deployed on Ethereum's Layer 2 Base, and DBS Token Services, a permissioned chain, addressing traditional cross-chain limitations and security challenges.
