This extension allows you to customise how currency will appear on your character sheet on D&D Beyond. It allows you to change the image, name and conversion text for each currency and even hide unused currencies.
You can have as many custom currencies as you want for as many different characters as you want. All this information is also shared across all your devices where you have the extension installed, so the currency will always be correct.
You can export and import the currencies and what characters use those currencies, so that everyone in your party can quickly be using the custom currency.
