How it works
Circle mints USDC when authorised partners send dollars to its bank accounts, and burns USDC on redemption. The reserves are held at regulated US financial institutions and BlackRock-managed treasury funds. A monthly attestation report details the breakdown. USDC is native on Ethereum and bridged to most major chains.
Example
You hold 50,000 USDC across Ethereum and Base. You can move it to Solana via a cross-chain bridge in minutes for a few dollars in fees. The receiving wallet sees the same dollar value, governed by the same redemption guarantee. To off-ramp, you sell USDC on Coinbase or a regulated exchange and receive a same-day or next-day bank transfer in your local currency.
Why it matters
USDC is the most institutionally-favoured stablecoin because of its reserve transparency and regulated issuer. The trade-off is slightly lower distribution than USDT outside North American and EU venues. In March 2023 USDC briefly depegged to about $0.87 after the Silicon Valley Bank failure stranded a portion of reserves; the peg restored within days as deposits were guaranteed, but the event clarified that even transparent stablecoins carry banking-system risk.
