Introduction to USDC
USDC (USD Coin) is a fully-reserved stablecoin pegged 1:1 to the U.S. dollar, designed to combine the stability of traditional finance with the innovation of blockchain technology. As one of the most trusted stablecoins in crypto, USDC serves as:
- A medium of exchange for fast, low-cost transactions
- A stable store of value during market volatility
- A foundational asset for DeFi protocols and smart contracts

How USDC Works
Reserve Backing and Transparency
Every USDC token is backed by:
- Cash deposits at U.S. regulated financial institutions
- Short-duration U.S. Treasury bonds
- Equivalent dollar-denominated assets
These reserves undergo monthly attestations by independent accounting firms (Grant Thornton) with public audit reports verifying the 1:1 backing.
Issuance and Redemption
- Minting: New USDC enters circulation when users deposit USD through authorized issuers
- Burning: USDC is permanently removed when redeemed for fiat currency
- Multi-chain availability: Native support across 15+ blockchains including Ethereum, Solana, and Polygon
