关于 USD Coin (USDC)
USDC is a fully regulated dollar digital stablecoin launched by Circle and Coinbase. USDC is fully backed by cash and short-dated U.S. government obligations, so that it is always redeemable 1:1 for U.S. dollars.
An eligible business can exchange USD for USDC and redeem USDC for USD through a Circle Account.
发行方与证明
USD Coin (USDC) is issued by Circle Internet Financial, operating under United States (Boston, MA) — regulated as a money transmitter in all 50 US states. Originally launched in 2018.
储备构成

锚定稳定性历史
USD Coin (USDC) is designed to trade at exactly 1.00 USD, with its peg defended through direct redeemability against off-chain reserves. Spot price currently sits at $0.9998, a -0.019% deviation from the target — well inside the stability band typical for reserve-backed dollar tokens.
reserve-backed 稳定币如何维护其锚定
Fiat-backed stablecoins maintain their peg through arbitrage: any time the secondary-market price drifts above $1.00, authorised participants mint new tokens by depositing dollars and sell them into the market; any time it drifts below, they buy on the open market and redeem 1:1 for dollars. The peg therefore depends entirely on (a) the reserves actually existing, (b) the issuer honouring redemption requests promptly, and (c) the issuer remaining solvent and unfrozen.
对持有者的实际影响
- Counterparty risk is concentrated in the issuer and its banking partners — a banking failure (as in the March 2023 USDC / SVB episode) can cause short-term depegs even when the underlying reserves are sound.
- Reserve attestations are not full audits. Always read the firm name, scope, and date of the latest attestation report before treating the peg as risk-free.
- Redemption rights typically apply only to verified institutional partners, not to retail holders. Retail exposure is exited via secondary markets, where liquidity matters most during stress periods.
- Regulatory action against the issuer (NYDFS orders, OFAC freezes, court-ordered blacklists) can immediately impair specific addresses or even the entire token.
- Mantapex tracks peg deviation in real time from DeFiLlama price feeds, but for high-value holdings cross-check directly on at least one independent venue (CoinGecko, the issuer's own dashboard, or an on-chain DEX).
Peg-stability commentary is based on the mechanism class (reserve-backed) and is provided for educational purposes only — it is not financial advice. Past peg stability is not a guarantee of future performance, and even the highest-quality stablecoins have historically traded outside their target band during banking, regulatory, or liquidity stress.

将 USD Coin 与其他 fiat-backed 稳定币比较
Below are the largest fiat-backed stablecoins tracked on Mantapex alongside USD Coin (USDC). Comparing supply and chain footprint within the same mechanism class is more meaningful than cross-class comparison, because the underlying peg-defence assumptions are different.
