Cryptocurrencies may be used within the current Four Party Model to settle transactions between a merchant and a consumer who may use or accept fiat and / or cryptocurrency. An intermediary wallet entity may assume the risk of cryptocurrency transactions. For example, a fiat-fiat transaction may follow the usual settlement process of the Four Party Model. In a crypto-crypto transaction, settlement may occur in real time. But in a fiat merchant / crypto customer transaction, settlement may be made from the customer's crypto wallet to an intermediary wallet. Fiat settlement would then occur between the intermediary and merchant following the Four Party Model. In a crypto merchant / fiat customer transaction, a transfer may be made from the intermediary wallet to the merchant's crypto wallet. Fiat settlement between the customer's bank (issuer) and intermediary can happen in the usual settlement process.
