USDC, which stands for USD Coin, is a type of cryptocurrency that is stored on the blockchain. It is an ERC-20 token, which means it is stored in cryptocurrency wallets that support the Ethereum blockchain. You can store USDC in various types of wallets, such as hardware wallets, software wallets, and online wallets. The key to accessing and managing your USDC holdings is your private key, which is used to sign transactions on the blockchain. It's important to keep your private key secure to protect your USDC funds.
