Digital banking platforms

Multi-currency accounts and payment rails beside your core

Digital banks and banking-as-a-service platforms need instant, multi-currency, always-on money movement without a core replacement programme. BLK Tech provides the ledger and rails that sit beside your core, with monitoring and reporting your control functions expect.

No core surgery

Wallet ledger and rails integrate beside your core rather than inside it.
