How AuraTap Holds Money — Architecture

This page explains the separation between AuraTap’s ledger system (what users are owed) and the actual funds held in segregated bank accounts (where the money is). This architecture ensures regulatory compliance and customer fund protection.

Core Principle: Ledger ≠ Bank Account

A wallet balance in AuraTap is a ledger entry — a record of what AuraTap owes the user. The actual money sits in segregated safeguarding accounts at licensed partner banks. These two layers must always reconcile.

The Two Layers

Understanding how ElRoiPay separates obligations from actual funds

The Ledger Layer

Wallet Ledger

The ElRoiPay ledger records what every user and merchant is entitled to. It is a database of obligations — not money itself. When a customer has GHS 500 in their ElRoiPay wallet, this is a ledger entry stating ElRoiPay owes them GHS 500.

Lives in ElroiPay’s database (PostgreSQL + Redis)
Double-entry bookkeeping model
Real-time — updates instantly on every transaction
Immutable — entries cannot be deleted, only reversed
NOT a bank account

PostgreSQL + Redis • Double-entry

The Safeguarding Layer

Bank Holding Account

The actual money backing all ledger entries sits in segregated trust accounts at licensed partner banks. These accounts are ring-fenced from ElRoiPay’s operating funds. In the event of ElRoiPay insolvency, these funds are protected and returned to customers.

Held at licensed partner banks in each country
Legally segregated — cannot be used for operations
Reconciled against ledger daily (must match)
Compliant with EMI safeguarding rules (EU PSD2, BoG, CBN)
THIS is where the money actually is

Licensed Banks • Ring-fenced • EMI Compliant

Ledger entries must always equal safeguarding balances — reconciled daily
