What is an Ethereum address?

An Ethereum address is a 42-character hexadecimal address derived from the last 20 bytes of the public key controlling the account with 0x appended in front. e.g., 0x71C7656EC7ab88b098defB751B7401B5f6d8976F. Basically, the Ethereum address is the "public" address that you would need to receive funds from another party through the Ethereum network.

Can I use the same address for ETH and ERC-20 tokens?

For non-custodial wallets, it would be fine to use the same address for both ETH and any ERC-20 token. However, with centralized exchanges, your account might have restrictions to where you can only send Ethereum (ETH) to an ETH address. Each ERC-20 token (i.e. COMP or USDC) might have its own unique COMP address or USDC.
