USD Coin (CRYPTO:USDC) is a digital dollar. It falls into the category of stablecoins, which are cryptocurrencies pegged to another asset. In USD Coin's case, the asset is the U.S. dollar, and 1 USDC is designed to maintain a value of $1.
Although stablecoins aren't investments, they have a variety of other uses, and you can often earn generous interest rates on them. Since its launch, USD Coin has become one of the largest stablecoins in the world and even become the first cryptocurrency selected for settling Visa (NYSE:V) transactions.
In this USD Coin guide, we'll explain how it works and how to decide if you should buy it.

What makes USD Coin unique?
In terms of functionality, U.S. dollar stablecoins essentially all offer the same thing. They aim to maintain a value of $1, and they work like any other digital currency so they can be transferred between crypto wallet addresses.
The most important factors for a stablecoin are transparency and trustworthiness. Those are also areas where USD Coin does a better job than most of its competitors.
Centre, the consortium that manages USD Coin, releases monthly attestations issued by Grant Thornton, LLP, one of the top accounting firms in the country. These attestations provide the number of USDC in circulation and the total value of the reserves backing USD Coin. That's important because it shows there are actual funds in an account for every USDC.
Another point in USD Coin's favor is the type of funds backing it. The USD Coin reserves used to have a mix of assets, including bonds and commercial paper. Centre decided to shift to cash and cash equivalents only, and it accomplished that in September 2021.
Where USD Coin came from
USD Coin was issued by Circle, a peer-to-peer payments company, and Coinbase Global (NASDAQ:COIN), a cryptocurrency exchange. Circle first announced plans to launch USD Coin on May 15, 2018, and raised $110 million.
The Centre consortium was established in 2018 to manage USD Coin. USDC became its first initiative when Coinbase offered USDC to its users. Circle and Coinbase are the founding members.
USD Coin launched on Sept. 26, 2018. According to its first attestation released in October 2018, there were about 127 million USDC in circulation. By the end of 2021, there were more than 51 billion. The company has since raised at least $1.1 billion.
How USD Coin works
USD Coin is built on an open-source fiat stablecoin framework developed by Centre. New USDC tokens are minted when people buy them, and they're removed from circulation when people sell their tokens for U.S. dollars.
Let's say you want to buy USD Coin through a crypto exchange. Here's how the three-step tokenization process works:
- You send U.S. dollars to the crypto exchange to purchase USD Coin.
- The exchange uses a USD Coin smart contract to mint the equivalent amount of USD Coin.
- You receive the newly minted USD Coin, and the exchange puts the U.S. dollars you paid into the reserves for USD Coin.
The tokenization process ensures there are reserves backing the entire supply of USD Coin.
If you're selling USD Coin, it's the same process only in reverse. The exchange uses a smart contract to remove the USDC tokens that you're selling from circulation, and it pays you an equivalent amount of U.S. dollars from the reserve.
USD Coin vs. Tether
USD Coin and Tether (CRYPTO:USDT) are the largest stablecoins by market cap. If you're planning to buy a U.S. dollar stablecoin, you may be wondering which one you should choose or if there's even a difference between them.
The stablecoins have the same uses and normally keep a value of $1. However, each has advantages over the other, so they're not entirely interchangeable.
USD Coin is widely considered to be the safer option because of its transparency. Its management has provided attestations since its launch, verifying its reserves. Tether Limited, on the other hand, didn't provide information on its reserves for years.
Tether's edge is its size. It has a much larger market cap than USD Coin (although the gap is shrinking) and a higher trading volume than any cryptocurrency. It will typically be a little easier to trade Tether for other cryptocurrencies due to its trading volume.
For investors, USDC also has the advantage of being subject to more regulatory oversight because it’s considered a stored value instrument in most U.S. states. Tether also hasn’t been independently audited yet.
Partnerships
USD Coin has inked a pair of major deals with Visa and Mastercard (NYSE:MA) that could help it dramatically expand as a payment method. In December 2020, Circle announced a partnership with Visa that would allow businesses in its payment network to accept USD Coin. In July 2021, Mastercard announced plans to test USD Coin as a payment method, and Stripe said in April 2022 that it would begin supporting USDC as a form of payment. Twitter (NYSE:TWTR) would be the first company to test the option by using it to pay content creators.
One of the reasons USD Coin is so widely used is that it's supported across multiple blockchains, and developers can swap it between all those blockchains. Here are blockchains that support USD Coin:
- Algorand (CRYPTO:ALGO)
- Avalanche (CRYPTO:AVAX)
- Ethereum (CRYPTO:ETH)
- Flow (CRYPTO:FLOW)
- Hedera (CRYPTO:HBAR)
- Solana (CRYPTO:SOL)
- Stellar (CRYPTO:XLM)
- TRON (CRYPTO:TRX)
Can I make passive income with USD Coin?
You can make passive income with USD Coin by lending it, and that's one of the reasons investors buy it. There are several crypto lending programs available that will pay you interest for lending your crypto. Gemini and CoinLoan are among the platforms that support USD Coin lending and offer competitive interest rates.
Since these are lending programs, they're not risk-free. It's unlikely that you'll lose any funds, but it is possible if borrowers default on their loans.

Unique risks
Since USD Coin is managed by multiple companies, the main risk is that one goes bankrupt. According to Circle, USD Coin is always redeemable 1:1 for U.S. dollars. But if Circle or Coinbase ends up going out of business, it's impossible to be 100% sure that USD Coin will maintain its value.
Stablecoin regulations are also a concern. U.S. lawmakers have been working on a regulatory framework for stablecoins and their issuers that could affect how they're used. It's worth mentioning that USD Coin follows current regulations and would likely have fewer issues with any new rules compared to other stablecoins.
These are relatively small risks, to be fair. With USD Coin's reserves, people who own it should always be able to exchange it for an equivalent amount of U.S. dollars. However, it's important to be aware that this isn't guaranteed. Although USD Coin acts as a digital dollar, it's not as safe as money in a bank account. Most banks have FDIC insurance that covers you if the bank collapses. USD Coin doesn't have this type of protection.
Is USD Coin a good investment?
As a stablecoin, USD Coin isn't designed as an investment. If it works the way it's supposed to work, any USD Coin you buy will be worth the same amount in one year, five years, and so on.
Even though it's not an investment, USD Coin is a great choice for a passive income stream. Through lending programs, you can easily earn an annual percentage yield of more than 5% on USD Coin, so you're taking on little risk for a generous return.
If you're looking for a cryptocurrency investment, it makes more sense to compare other types of cryptocurrencies that aren't stablecoins. Bitcoin (CRYPTO:BTC) and Ethereum are popular choices, but there are many other interesting projects out there. You could also try investing in cryptocurrency stocks.
How to buy USD Coin

USD Coin is useful for individuals and businesses wanting a digital dollar. It's easy to use, whether you're sending, receiving, or lending. Stablecoins aren't guaranteed, but the transparency of USD Coin makes it one of the most secure options.
