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.

Methods and systems are presented for providing a framework for facilitating time-sensitive cryptocurrency transactions for users. When a request for processing a time-sensitive cryptocurrency transaction using funds from a cryptocurrency wallet is received from a user, a transaction system first verifies whether the cryptocurrency wallet has a balance to cover the cryptocurrency transaction. The transaction system also verifies the ownership of the cryptocurrency wallet based on an asynchronous method. The user generates verification data without any input from the transaction system, and based on a private key associated with the cryptocurrency wallet, a generator function, and a user-generated value. Without knowing the user-generated value, the transaction system verifies the ownership of the cryptocurrency wallet based on the verification data, and processes the transaction for the user.
