To compensate for the exchange rate risk, merchants tend to charge a higher price in cryptocurrencies compare to in fiat currency, which dampens the incentive of customers to choose cryptocurrencies as the means of payment.

This work devises a novel ERC 1 standard to resolve the payment at a predetermined exchange rate that can be employed by any existing cryptocurrency.

Universal currency Because cryptocurrencies are digital, this means they are not attached to any country or limited to any geographical boundaries. What this also means is that there are no transaction fees, exchange rates, or interest rates involved when using this form of currency.
