The account-validation layer a central bank now runs on.

Account Mapper is the national account-validation and BBAN layer adopted by the Central Bank of Liberia under the World Bank-funded LIFT-P programme. I owned the API product — Ingress and Name Enquiry contracts, versioning, acceptance testing — and drove integration across nine commercial banks, with the architecture reviewed against digital public infrastructure standards.

Step 01 — Discovery

Recurring payment failures that nobody had traced to their root cause.

CPay was processing government payments across Liberia when a pattern emerged in the support data: a disproportionate number of failed or misdirected payments were linked to account number entry. Staff were manually entering Basic Bank Account Numbers (BBANs), and the system had no validation layer to catch errors before processing.

The support tickets described the symptom — payment failed, payment went to wrong account — but nobody had traced the root cause. I pulled three months of failure logs and found that 68% of payment errors were attributable to BBAN entry mistakes.
