USDC meaning: what is USDC (USD Coin)?

What USDC is

USDC is the second largest dollar stablecoin after USDT. A stablecoin is a crypto token built to hold a steady price, and USDC targets exactly one US dollar. It launched in 2018, created by Circle together with the exchange Coinbase, and today Circle issues and manages it on its own.

The mechanism is simple. A business sends Circle dollars and receives the same number of USDC; when it returns USDC, Circle destroys the tokens and pays out dollars. Ordinary users rarely deal with Circle directly. They buy and sell USDC on exchanges, where market makers keep the price close to $1 because they can redeem with Circle if it drifts.

Circle says the reserves are held in cash at banks and in a money market fund that invests in short-dated US Treasury bills, and it publishes monthly reports on them that an accounting firm reviews. That transparency is the main reason some traders and businesses prefer USDC.

Which networks USDC runs on

USDC is a token on top of other blockchains, not a blockchain of its own. At the time of writing (November 2026) Circle issues it natively on many networks, including:

Two details catch people out. First, Circle stopped supporting USDC on Tron in 2024, so many exchanges no longer offer a TRC20 option for it, even though TRC20 is the usual cheap route for USDT. Second, some chains carry a bridged or exchange-issued version (for example a "pegged" USDC on BNB Chain) that is backed by USDC held elsewhere rather than issued by Circle. It usually trades at the same price, but it is a different token with an extra layer of trust.

All the Ethereum-compatible chains share the same 0x address format, so an address alone does not tell you which network it belongs to. Choose the network on the withdrawal screen that the receiving wallet or exchange lists for USDC, and send a small test amount first to a new address.

How traders use USDC

USDC does the same jobs as other dollar stablecoins:

• Parking value. Selling a coin into USDC steps out of the market without a bank withdrawal.
• Quoting prices. Many exchanges list pairs such as BTC/USDC alongside BTC/USDT; see trading pairs and quote currencies.
• Moving money. Sending USDC on a low-fee network is often faster than a bank transfer, especially across borders.

Where it differs is in who tends to hold it. Regulated platforms, payment companies and decentralised finance apps on Ethereum-compatible chains often favour USDC, while USDT dominates trading volume on large offshore exchanges. In the EU, some platforms have restricted USDT and kept USDC for local customers under the MiCA stablecoin rules, which is a practical reason a European trader might see more USDC.

The risks of holding USDC

• Reserve and banking risk. In March 2023 Circle disclosed that part of its cash reserves sat at Silicon Valley Bank, which had just failed. USDC fell well below $1 over a weekend and recovered once US authorities protected the bank's depositors. The episode showed that even cash reserves carry the risk of the bank holding them.
• Issuer control. Circle can freeze USDC at specific addresses, and does so under legal orders. That is a feature for regulators and a risk for a holder whose address is flagged.
• Operational risk. Most losses are mistakes: the wrong network, a bridged token the receiver does not accept, or a mistyped address.
