- Each supported blockchain has its own USDC contract and count.
- Circle publishes periodic attestations of reserves and circulation.
- Redemption at par depends on Circle's terms and limited access.
- A market price below one dollar can happen even with reserves.
USDC is a stablecoin that Circle Internet Group issues and pegs to the US dollar. It began on Ethereum as an ERC-20 token and later spread to other blockchains.
What makes USDC supply change?
Circle creates USDC when a business customer sends dollars. It destroys USDC when it pays out a redemption. Circle says reserves cover each token, and it describes them as mainly cash and short term US Treasuries.
How does minting and redemption work?
Each supported blockchain has its own contract for minting and burning. In February 2024, Circle discontinued USDC on TRON, and customers had until February 2025 to move tokens off. Redemption at par depends on Circle's terms, and access can be limited.

- 4Receive the payoutAfter Circle confirms, it sends USDC for a mint or pays dollars for a redemption under its terms.
Where can you track USDC supply?
No single explorer shows total USDC supply because the token runs on more than one blockchain. Circle publishes periodic attestations of reserves and circulation. Deloitte became its reserve auditor in January 2023.

- Deloitte: reserve auditor since January 2023.
- Network explorers: one blockchain's USDC each.
- Blockchain dashboards: separate counts per network.
What can break the USDC peg?
A market price below one dollar is possible even if Circle says reserves are intact. In March 2023, Silicon Valley Bank's failure put $3.3 billion of Circle's reserves at risk, and USDC briefly traded below its peg. It regained the peg four days later.
Frequently asked questions
Circle serves business customers. A regular exchange user usually cannot mint or redeem directly with Circle.
Circle says it releases the reserve assets tied to burned tokens, so reported reserves match remaining tokens.
Minting and burning on that network can pause, while USDC counts on other blockchains stay separate.
USDC is issued by a company that says it holds reserves. Many algorithmic stablecoins rely on code and sometimes a second token.
