Exchange rates

EUR is the system's base currency. Every other currency stores its rate as a ratio to EUR. Rates are updated automatically by a background sync service and are not manually editable. The Updated At column shows when the last successful sync occurred for each currency.

The EUR-normalised rate is used to compute the Volume metric — all payment amounts are converted to EUR at the rate recorded at the time of the transaction.
