The transfer between Singapore and the U.S. occurred during a non-banking period and utilized Swift's Digital Ledger to bypass the standard two business day processing window. This transaction marks the first instance of tokenized deposits being used for a cross-border USD payment between DBS and Citi.

The partnership provides a 24/7 payment rail on a blockchain-based ledger to enable instant transfers without the restrictions of banking hours. This system removes the need for manual reconciliation and clearinghouse delays that traditionally slow funds moving across different time zones.
