USDC

USDC is the stablecoin that bet its future on regulation. Issued by Circle — a US public company since 2025 — it holds its reserves in cash and short-term US Treasuries, publishes monthly third-party attestations, and positioned itself as the compliant dollar of crypto years before compliance was fashionable. This hub collects MEXC Learn's USDC coverage. Start with the mechanics if you are new, because a stablecoin is only as good as the machinery holding it at one dollar. The coverage splits three ways. Reserves and the peg. USDC's dollar backing sits largely in a government money market fund and cash at banks, disclosed monthly. The peg holds through redemption: anyone eligible can return USDC to Circle for dollars, and that arbitrage pulls the market price back whenever it drifts. The one time the machinery genuinely failed — the 2023 banking-crisis weekend, when USDC traded well below a dollar — is covered here honestly, because it is the most instructive event in the token's history. Regulation. USDC operates under US money-transmission rules, the EU's MiCA framework, and the 2025 US federal stablecoin law. Articles here cover what those regimes actually require and what they change for holders. Use and comparison. Where USDC fits against USDT — the transparency-versus-liquidity trade that defines stablecoin choice — plus the centralisation facts both share: issuer freeze powers, blacklists, and what "backed" does and does not mean. Every guide explains the mechanism, not the marketing.

USDC (FAQ)

A dollar-pegged stablecoin issued by Circle, a US financial technology company that went public in 2025. Each USDC is redeemable one-for-one for dollars from Circle, with reserves held in cash and short-term US Treasuries. It launched in 2018 and became the second-largest stablecoin by positioning itself as the transparent, regulated alternative in a market that historically had neither.

Cash and short-dated US government debt. The bulk sits in a dedicated, SEC-registered government money market fund managed by BlackRock, with the remainder in cash at banks. Circle publishes monthly attestations from a major accounting firm listing the composition. Attestations verify holdings at a point in time — they are narrower than a full audit, though Circle's corporate financials are separately audited as a public company.

Once, seriously. In March 2023, Circle disclosed that part of its cash reserves was stuck at the collapsing Silicon Valley Bank, and USDC traded as low as roughly $0.87 over the weekend. When US authorities guaranteed the bank's deposits, the peg snapped back within days. The lesson was precise: USDC's risk was never the Treasuries — it was the banking layer holding the cash portion.

Different bets. USDC optimised for regulatory standing and disclosure: US and EU frameworks, monthly attestations, conservative reserves. USDT optimised for reach and liquidity: it dominates trading pairs and emerging-market usage, with a more varied reserve mix and quarterly attestations. USDT is where the volume is; USDC is where the compliance is. Most serious users end up touching both, for different jobs.

Deposit and withdraw it across supported networks, trade it against other assets, and use it as a borrowing option — MEXC Loans pays out in USDT or USDC against posted collateral. Worth knowing going in: USDT is the dominant quote currency on MEXC, so most pairs and futures settle in USDT; USDC's role on the platform is real but narrower. Check live listings for current pairs.
