# What's a wallet address? A wallet address is a public address that is associated with a crypto wallet. It is typically represented as a randomly generated string of characters. **This address is used to send and receive cryptocurrency, making it safe to share with others.** Some examples of when you might share your wallet address include when friends want to send you tokens or NFTs or when you want to be on the whitelist for a specific project or airdrop. Additionally, your wallet address can be used to locate *transaction hashes* on a *block explorer*. Your wallet address can be found within the crypto wallet that you are using. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
