Transaction Audit Trail & Reconciliation Trace
4 Events Recorded
Corridor Context: In the historic DBS-Citi production transaction, a USD cross-border transfer initiated on a Saturday bypassed traditional clearing cutoffs. Instead of locking up $5M in nostro/vostro pre-funding across intermediaries until Tuesday morning, the Swift Digital Ledger orchestrated simultaneous payment validation, cryptographically verified liquidity availability, and finalized the payment in 8.5 minutes.
