Ethereum is a versatile blockchain supporting decentralized finance (DeFi), non-fungible tokens (NFTs), gaming, and more. Its native token, ETH, ranks as the second-largest cryptocurrency by market capitalization. To interact with Ethereum, you'll need an Ethereum wallet address—a unique identifier for sending, receiving, and storing ETH and ERC-20 tokens.
This guide covers everything from wallet basics to setup steps and security best practices.
Understanding Ethereum Wallet Addresses
What Is an Ethereum Wallet Address?
An Ethereum address is a 42-character hexadecimal string starting with "0x" (e.g., 0x71C7656EC7ab88b098defB751B7401B5f6d8976F). It functions like a bank account number for:
- Sending/receiving ETH.
- Holding ERC-20 tokens (e.g., USDT, USDC).
Ethereum Contract Addresses Explained
Contract addresses identify smart contracts deployed on Ethereum. Unlike wallet addresses, they execute predefined code and are critical for DeFi, NFTs, and dApps.
Case Sensitivity in ETH Addresses
Ethereum addresses are case-insensitive. 0xAAAAA and 0xaaaaa refer to the same account.
How to Locate Your Ethereum Address
- Open your wallet’s "Receive" section.
- Select ERC-20 network for Ethereum.
- Copy the 0x-prefixed hexadecimal string.
