What is a Wallet Address?

Learn what blockchain wallet addresses are, how they work, and the differences between addresses on Ethereum, Bitcoin, and Solana.

What is a Wallet Address?

A wallet address is a unique string of characters that identifies a destination on a blockchain. It's like a bank account number -- you share it with others so they can send you cryptocurrency.

How Addresses Work

Addresses are derived from public-key cryptography:

  1. You generate a private key (a secret random number). This is like your password -- never share it.
  2. The private key generates a public key through a one-way mathematical function.
  3. The public key is hashed to create your address -- the short, shareable identifier.

Address Formats by Chain
