SARB PayShap overlay
SADC-RTGS operator.
SARB PayShap overlay →Botswana · BoB
A SADC SIRESS node with diamond-export FX needs a high-value overlay, not a retail dashboard. Nexus is that settlement overlay for Bank of Botswana.
High-value export FX and IMTO corridors are different files. SIRESS participation without live IMTO telemetry is a half picture.
Target module: high-value settlement overlay. Pair with SARB.
On-premise under BoB control.
