USDC: the world's leading digital dollar stablecoin


Why use a digital dollar stablecoin?

Digital money for the digital age

USD Coin (USDC) represents a major breakthrough in how we use money. Digital dollars work like other digital content — they move at the speed of the internet, can be exchanged in the same way we share content, and are cheaper and more secure than existing payment systems.

Trust, transparency and compliance

USDC is fully backed by cash and equivalents and short-duration U.S. Treasuries, so that it is always redeemable 1:1 for U.S. dollars. Each month, we publish attestation reports by Grant Thornton regarding the reserve balances backing USDC.

USDC Institutional Trading Program

Our new program has been designed to meet the needs of high volume trading firms, crypto exchanges and market makers.

The largest stablecoin ecosystem

As an open standard and public smart contract, USDC has rapidly grown the largest stablecoin industry ecosystem in the world. Hundreds of companies, products and services support the USDC standard, including digital wallets, exchanges, DeFi protocols, savings, lending and payment services. USDC is creating value for the entire blockchain ecosystem.

And a bit of DeFi in the mix to boot. From Boston to London to Seoul to Buenos Aires to Jakarta to Mumbai, here’s the future of how money moves.
