Hey there, @Vitalijs1988
Bo here from Shopify Support!
That is a really great question. This is not possible, Shopify Payments can only be used in stores that are based in supported countries. We are rapidly expanding our payment gateway to more countries. To do so, we need to make sure that the version of our gateway we launch in said country is compliant to the requirements of that country so while we would like to provide the service to all merchants immediately, our banking partners cannot do this.
To use Shopify Payments you need to be based in a supported country (your store address and IP address must reflect this), use a supported currency and have a bank account in the same country that you are based in. So for the meantime, while you are running your business in Ireland, you can absolutely use Shopify Payments. When you move away and start operating your store from a country where Shopify Payments are not available you will need to use a supported thid party gateway. You can find a list of these here.
All the Best,
