A medium of exchange is 'something of value' exchanged for goods and/or services. An important characteristic of a medium of exchange is that it represents a generally accepted standard of social value.
How a Medium of Exchange Works
A medium of exchange is not necessary for commerce. Goods and/or services can be exchanged for like value (see: barter) however, due to the lack of divisibility of goods and services, mediums of exchange are preferential.
A medium of exchange is an intermediary component of most transactions and can be anything (tangible or intangible) that is generally accepted by the parties to the transaction.

For a medium of exchange to exist, it must fulfill these 6 characteristics:
- Durability - Must be made to last
- Portability - Easy to transport
- Acceptability - The parties to the transaction must agree to its use
- Divisibility - It must be easily divided
- Uniformity - It must be of similar size, shape, and unit of measure
- Supply - The supply must either be fixed or otherwise regulated
Historical Examples of a "Medium of Exchange"

Are Stable Coins (Crypto) a Medium of Exchange?
Yes, stablecoins are a type of medium of exchange.
Stablecoins are a type of cryptocurrency that is designed to maintain a stable value, typically by being pegged to a fiat currency, such as the US dollar or the Euro, or to a commodity, such as gold or silver.
Stablecoins offer many of the benefits of traditional cryptocurrencies, such as fast and low-cost transactions, while also offering the stability of a fiat currency. This can make them a popular choice for individuals and businesses looking to use cryptocurrencies for everyday transactions, such as online purchases or cross-border transfers.
Stablecoins also offer the potential for increased financial inclusion, as they can be used by individuals and businesses in countries with unstable currencies or limited access to traditional banking services. They can also be used for remittances, allowing individuals to send money across borders quickly and affordably.
However, it is important to note that stablecoins also come with their own set of risks and considerations, including the potential for fraud or market manipulation, as well as regulatory risks.
Cryptocurrency stablecoins offer a new and unique medium of exchange. One of the largest drawbacks to cryptocurrencies is their high price volatility and stable coins offer the market a more "stable" alternative.
