USD Coin (USDC) is a digital dollar stablecoin and a child of Circle and Coinbase's consortium. According to Circle, USDC is issued by regulated financial institutions, backed by fully reserved assets and is redeemable on a 1:1 basis for US dollars (i.e. its price is always $1).
As a stablecoin, historically it has been less volatile than most other digital currencies. With USDC, you can transfer money across borders quickly and easily, without having to rely on any middleman.
