Bundle: High-Speed Financial Settlement & Ledger Engine
Double-entry cryptographic ledger and automated multi-currency settlement engine built for institutional transactions.
The Challenge
Bundle’s rapid cross-border payment expansion strained their initial accounting ledger. Multi-currency settlements suffered from rounding discrepancies and lacked real-time balance reconciliation.
The Solution & Architecture
WDL designed an immutable, double-entry ledger architecture in PostgreSQL utilizing strict serializable isolation levels, cryptographic transaction hashes, and automated end-of-day bank reconciliations.
