Multi-currency wallet software, with every currency on a balanced ledger

Each customer has one balance per currency. A conversion is two postings, one in each currency, through your treasury account, with your margin in the rate. The customer sees the rate, the fee and the final amount before confirming.

Rates come from one table where treasury sets buy and sell rates. A route stops quoting when its rate is missing or too old, so a stale price never reaches a customer.

Most search results for this term are crypto wallets. This is a fiat system for regulated money: bank accounts, mobile wallets, cards and cash, with identity checks, screening and limits on every transfer.

Use it for customers who earn in one currency and spend in another, for traders who pay suppliers abroad, and for companies that hold currency accounts with their own statements. It runs with our remittance product or inside a mobile money service.

Each conversion leaves you long one currency and short another. If a thousand customers buy dollars on a day the rate moves against you, your margin can go in an afternoon. So treasury needs to see the position per currency during the day, not at month end, and needs one place to change rates at once.

Ask any vendor how a rate change reaches customers and where you read your positions. A wallet that hides this is passing the risk to you without telling you.

Every currency needs its own bank or partner account, and each of those must match the ledger. A mismatch in one currency should not be hidden by a surplus in another. Daily reports per partner and currency are what let finance sign off with confidence, and they are the first thing an auditor will ask for.

Before confirming, the customer should see the rate, the fee and the exact amount that arrives. Showing a fee of zero and hiding the cost in the rate breaks trust once people compare. Show the receipt with both currencies, and keep a statement for each one, so a trader can hand it to an accountant.
