How USDC works
USDC, or USD Coin, is a US dollar stablecoin issued by Circle. Each token is backed 1-to-1 by cash and short-duration US treasuries held in segregated accounts, with monthly attestations published by a major accounting firm. That transparency is its defining feature: you can check the reserves rather than take them on faith, which has made USDC the preferred dollar token for regulated and institutional flows.
Worked example
You sell a volatile altcoin into USDC at $1.00 to step out of risk. The value sits in dollars on-chain, no bank wire, and you can swap back into the market in seconds when conditions improve. USDC behaves as cash between trades, the same role USDT plays, with a more conservative and more disclosed backing.
USDC on Volity
Volity accepts USDC deposits on the major chains with zero deposit fees, and they clear in minutes. It is one of the fastest ways to fund a Markets account and a natural settlement currency for crypto CFDs. For traders who care about reserve quality, USDC is the conservative default among dollar tokens.
Why it matters
Even a well-backed stablecoin is an issuer liability, not a bank deposit, and it briefly lost its peg during the 2023 banking stress before recovering. Transparency reduces that risk but does not erase it. Prefer disclosed reserves and clear redemption rights, and treat any stablecoin as working capital, not a savings account. Related: DeFi.
