USDC (USD Coin) is a stablecoin that aims to maintain a 1:1 peg with the US dollar. It is issued by regulated financial institutions and its reserves are regularly audited to ensure that each USDC in circulation is backed by an equivalent amount of US dollars. While this can provide a level of security, no investment or financial asset can be guaranteed to be 100% safe. It is always important to carefully consider risks and conduct your own research before using any financial product or service, including stablecoins like USDC.
