USD Coin (USDC) is a digital currency that is pegged to the price of the US dollar, making it a stablecoin. Initially based on the Ethereum blockchain as an ERC-20 token, USDC is now supported on various other blockchain platforms, including Algorand, Solana, Stellar, and more.

USDC is issued in collaboration with financial institutions and cryptocurrency companies, with cash and short-term US government bonds serving as collateral, maintaining a 1:1 peg to the US dollar.

USDC is the second-largest stablecoin by market capitalization, just behind USDT (Tether). Its key advantages include price stability, traceability, and a convenient digital payment method. It is commonly used in cryptocurrency trading to mitigate price volatility and can also be utilized in decentralized finance (DeFi) platforms for deposits, lending, and earning interest. The issuance and management of USDC are typically subject to regulatory oversight to ensure legality and transparency.
