Question 1

What is USDC?

Accepted Answer

USDC is a digital dollar token issued by Circle. It is a fiat-backed stablecoin and can be used in native form on multiple blockchains supported by Circle. It is a digital token on a blockchain, not the U.S. dollars in a bank account themselves. Availability on a given chain depends on whether Circle has issued a native version and whether a wallet or service supports that network.

Question 2

What is the relationship between USDC and the U.S. dollar?

Accepted Answer

Circle states that USDC is redeemable for U.S. dollars at a 1:1 rate, meaning that an eligible redemption uses 1 USDC for 1 U.S. dollar. This arrangement does not mean that the secondary-market price must equal 1 U.S. dollar at every time. Issuance refers to eligible customers obtaining USDC through applicable processes; redemption refers to returning USDC and exchanging it for U.S. dollars under the terms. Eligibility and service restrictions are governed by Circle's terms.

Question 3

How does USDC's supply change?

Accepted Answer

USDC has no fixed total supply. Its supply changes with issuance and redemption: issuance increases circulating USDC, while redemption reduces the corresponding circulating USDC. Circulating supply should be understood as data at a particular point in time on the transparency page, rather than as a permanent cap or the amount instantly tradable in the market.

Question 4

Where can I view USDC reserve information?

Accepted Answer

Circle discloses USDC reserve composition and circulating supply on its transparency page as supporting information for the 1:1 U.S. dollar redemption description. Reserve information describes the assets backing circulating USDC, while circulating supply describes tokens that have been issued and not yet redeemed. Both change over time.

Question 5

What is the difference between native USDC and a bridged version?

Accepted Answer

Native USDC is the version directly issued by Circle on a specified supported chain; Circle's service support is based on these native versions. A bridged version is mapped through a cross-chain mechanism and is not directly issued by Circle on the destination chain. Even when the names are the same, their issuance paths, service support, and handling may differ.

Question 6

How can I transfer USDC safely?

Accepted Answer

Before transferring USDC, confirm that the sending network, recipient address, and the specific USDC version supported by the recipient all match. If the receiving service does not support that chain or version, the assets may not be automatically recognized or processed. The sending transaction also requires a network fee on the sending chain, which is not determined by USDC's 1:1 redemption rate.

Question 7

What can USDC be used for?

Accepted Answer

USDC can be used for on-chain transfers, payment settlement, and dollar-denominated or liquidity-related uses in supported exchanges or applications. Costs, confirmation methods, and application support vary among networks. A platform's own conversion, trading, or withdrawal rules also do not automatically become the same simply because the asset is named USDC.

Question 8

How can I confirm whether a blockchain supports USDC?

Accepted Answer

The list of networks supporting native USDC can change and should be confirmed using Circle's supported-blockchains information. You need to confirm that Circle supports native USDC on the chain, that the sending service can send from that chain, and that the receiving service can receive USDC on that chain.

Question 9

Why do I still need to pay network fees when using USDC?

Accepted Answer

The cost of an on-chain USDC transfer is determined by the network fee of the blockchain used, not by Circle's U.S. dollar redemption rate. Even when the asset is dollar-denominated, actual fees can differ across networks or congestion conditions. The sender must hold the native fee asset required by that network.

Question 10

Is USDC platform credit?

Accepted Answer

USDC is a digital token issued by Circle Internet Financial, LLC and operating on supported networks; it is not platform credit. USDC can be transferred between addresses on supported blockchains. However, when using conversion, custody, or trading services, applicable rules of both that service and Circle still apply.

Question 11

Why does 1:1 redemption not mean every market price is fixed at 1 U.S. dollar?

Accepted Answer

1:1 redemption, reserve disclosure, and secondary-market trading are separate layers. The redemption arrangement specifies the rate for eligible redemptions, the transparency page discloses reserves and circulating supply, and secondary-market prices are formed by trading on venues. Therefore, redeemability at 1:1 should not be understood to mean that the executed price must be 1 U.S. dollar at every time, on every platform, or for every version.

Question 12

Where can I find official information about USDC?

Accepted Answer

Circle's product page helps confirm product positioning; the transparency page covers reserves and circulating supply; the terms describe issuance and service rules; and the supported-blockchains information confirms the scope of native USDC. When transferring USDC or determining its version, use the supported-blockchains information to verify the specific chain and native version rather than relying only on a token name or icon.
