USDC (USD Coin) is a stablecoin pegged 1:1 to the US dollar, issued by Circle. Each USDC token is intended to be redeemable for one dollar, and it is backed by a reserve of cash and short-dated US Treasuries held with regulated financial institutions. It is one of the largest and most widely used dollar stablecoins.
How USDC keeps its $1 peg
USDC is a fiat-backed stablecoin. For every token in circulation, Circle holds approximately one dollar of reserves. New USDC is minted when dollars are deposited and burned when tokens are redeemed for dollars. Because tokens can be created and redeemed at $1 by eligible institutions, market arbitrage keeps the trading price very close to a dollar.
What backs USDC
USDC’s reserves are held primarily in cash and short-duration US Treasury bills, much of it through a dedicated, ring-fenced government money-market fund. Circle publishes regular third-party attestations of those reserves, which is a key reason USDC is often viewed as one of the more transparent stablecoins.
Where USDC is used
- Trading: a stable base pair on exchanges, used to move in and out of volatile assets.
- DeFi: collateral, lending, and liquidity across decentralized protocols.
- Payments and transfers: moving dollars on-chain quickly and at low cost, 24/7.
USDC is natively available on many blockchains, including Ethereum, Solana, Base and others.
USDC vs. USDT
USDC and USDT both target a $1 peg, but they differ in issuer and reserve disclosure. USDT (Tether) is the largest stablecoin by market value; USDC is often preferred by users who prioritize reserve transparency and a US-regulated issuer. Both are fiat-backed rather than algorithmic.
Risks to understand
No stablecoin is risk-free. USDC depends on the quality of its reserves, the solvency of the institutions holding them, and the issuer’s ability to honor redemptions. It briefly traded below $1 in March 2023 when part of its cash reserve was held at a bank that failed, before recovering once those funds were confirmed safe — a reminder that “stable” does not mean “guaranteed.”
