What Is a Crypto Wallet Address?

2026-07-02

A crypto wallet address is a string of characters — like an account number — that you share so others can send you cryptocurrency. It's safe to share, but it must never be confused with your private key or seed phrase. This guide explains how addresses work.

Where an address comes from

Your wallet address is derived from your public key using cryptography, and it works like the account number you give someone to receive a payment [1]. Each network has its own address format — a Bitcoin address looks different from an Ethereum address (which starts with "0x") — and sending to the wrong network's address can lose funds [2].

Sharing safely

The bottom line

A wallet address is your public "receive" identifier — share it (often as a QR code) to get paid. It's derived from your public key and differs by network, so always match the address to the right coin and network, and double-check it before sending. Crucially, share your address freely, but never your private key or seed phrase.
