In traditional financial (TradFi) systems, national currencies like the US dollar or euro serve as units of account. In the context of cryptocurrencies, a unit of account refers to the function of a digital currency to serve as a standardised measure of value for goods, services, assets, or debt within an economy. The use of a cryptocurrency as a unit of account is one of the three main functions of money, alongside being a medium of exchange and a store of value.
Cryptocurrency coins or tokens can function as units of account. For example, Bitcoin (BTC) or Ethereum (ETH) can be used as a reference point to assess and compare the value of other cryptocurrencies or assets. However, in the volatile and rapidly evolving cryptocurrency market, some assets may experience significant price fluctuations, which can impact their suitability as stable units of account for everyday transactions.
Stablecoins, which are pegged to the value of traditional currencies or commodities, aim to address this volatility issue and provide a more stable unit of account within the cryptocurrency space.
