WebMoney users' funds are stored in a "purse", which holds electronic money corresponding to an underlying asset, such as a currency.[1] The underlying assets for WebMoney units are held by a global network of companies that act as guarantors for the payment system.[5] Guarantors accept deposits in the underlying assets and issue the corresponding WebMoney units.[6] WebMoney Transfer can be used for peer-to-peer payments, and includes an escrow system.[7] It charges 0.8% of the transacted amount in fees, up to a maximum fee of €50.[7]
