This is not exactly possible at the moment.
There will be shortcodes in the future to display coin rates.
At the moment you can do the following in JavaScript on the frontend:
- The coin that exchange rates are given against is indicated by
walletsUserData.fiatSymbol. This is normally the selection under Wallets > Exchange rates > Default fiat currency but can be overridden in a user’s profile. - The exchange rate for e.g. Litecoin is accessible as
wp.wallets.viewModels.wallets.coins()['LTC'].rate.
Hope this helps. Once the shortcodes are ready I will report it and there will also be a blog announcement.
kind regards
