How Does USDC Work? USD Coin Mechanics
1. The Minting and Burning Process
USDC uses a minting and burning mechanism to maintain its dollar peg and ensure supply matches reserves.
When someone deposits one US dollar into their Circle account, one USDC token is minted and created on the blockchain.
Conversely, when a holder redeems one USDC for cash, that token is permanently burned (destroyed) to maintain the 1:1 ratio.
This process ensures the number of USDC tokens in circulation always matches the dollar amount held in reserve.
2. What Backs USDC?
Each USDC is backed by fully reserved assets held in segregated accounts at regulated US financial institutions.
Circle's reserves consist of cash and short-term US Treasury bonds, which are considered among the safest dollar-denominated assets.
The reserve portfolio is held at the Bank of New York Mellon, and Circle engaged Deloitte as its auditor for USDC reserve reporting in January 2023.
Monthly attestation reports from Deloitte verify that reserves match circulating supply, providing transparency that addresses the question "what is USDC backed by.
- You can also verify transactions using a USDC explorer.
3. Multi-Blockchain Availability
USDC started on Ethereum using the ERC-20 token standard but now operates across multiple blockchain networks.
Major blockchains supporting USDC include Ethereum, Solana, Algorand, Stellar, Polygon, Base, and Near.
This multi-chain compatibility allows users to choose networks based on transaction speed, cost, and specific use cases.

Circle discontinued USDC on TRON in February 2024 following a risk management review, demonstrating active oversight of which networks support the stablecoin.
