USDC is a stablecoin pegged to the US dollar, maintaining a value near $1.00. This stability makes it a popular quote currency in many crypto pairs.

For example, BTC/USDC means trading Bitcoin against USDC, with the price showing how much USDC you need for one Bitcoin. Similarly, you'd find ETH/USDC or SOL/USDC. USDC pairs are generally liquid and serve as convenient "on-ramps" and "off-ramps" for crypto trading, allowing for stable entry and exit points in the market .
