USDC is the stablecoin that positioned itself as the compliant, transparent alternative to Tether from day one. Launched in 2018 by Circle, initially under the Centre consortium with Coinbase, USDC is pegged 1:1 to the US dollar and backed by cash and short-dated US Treasuries held with regulated custodians.
What it does
Circle publishes monthly attestations from a major accounting firm detailing USDC's reserve composition, a level of disclosure that's made it the preferred stablecoin for institutions, fintechs and regulated exchanges wary of Tether's opacity. USDC circulates across more than a dozen blockchains including Ethereum, Solana and Base, with Circle's Cross-Chain Transfer Protocol (CCTP) letting it move natively between them rather than relying on wrapped versions. It's become core DeFi collateral, a settlement currency for payments firms including Visa pilots, and — following Circle's June 2025 IPO on the NYSE — a much more publicly scrutinised business than it was as a private company.
USDC's growth has tracked the broader institutionalisation of crypto: as regulated players entered the space, they gravitated toward the stablecoin with the clearest paper trail and US banking relationships.
Risks
That US banking dependency became a real problem in March 2023, when $3.3 billion of USDC's reserves were temporarily stuck at the failed Silicon Valley Bank, causing USDC to de-peg to roughly $0.87 before US regulators guaranteed deposits and the peg was restored within days. The episode showed that even a well-regulated stablecoin carries counterparty risk through its banking partners. USDC's future is also increasingly tied to US legislation — the 2025 GENIUS Act set federal rules for payment stablecoins, which favours compliant issuers like Circle but also raises the bar and cost of staying compliant. Competition remains intense from Tether's liquidity advantage and a growing wave of bank-issued and PayPal-style stablecoins entering the market.
USDC's bet is that transparency and regulatory alignment win out over raw liquidity in the long run — a bet that's looked increasingly right since 2023, if not yet fully proven.
