USDC: The Dollar-Backed Stablecoin You Need to Understand
Learn about USDC — how it maintains its peg, its multi-chain availability, and its role in DeFi trading.
What Is USDC?
USD Coin (USDC) is a fully-backed stablecoin issued by Circle. Each USDC token is backed 1:1 by US dollars held in regulated financial institutions. It is the second-largest stablecoin by market cap.
How USDC Maintains Its Peg
- Full reserves: Backed by cash and short-term US Treasuries
- Monthly attestations: Independent accounting firms verify reserves
- Regulated issuer: Circle is a licensed money transmitter
- Arbitrage mechanism: Authorized parties can mint/redeem at $1.00
Multi-Chain USDC
USDC is available natively on Ethereum, Arbitrum, Base, Optimism, Polygon, Avalanche, Solana, and many more chains. Native USDC (issued by Circle directly on each chain) is preferred over bridged variants.
Uses in DeFi
- Trading pair: Most common quote currency on DEXs
- Lending collateral: Earn yield by lending on Aave, Compound
- Stablecoin farming: Low-risk yield in stablecoin-only pools
