An Ethereum (ETH) address is a unique string of characters used to send and receive coins. Every Ethereum address is made up of 42 characters and always starts with 0x. For example:
These are valid Ethereum address examples. They might look complicated, but once you understand the pattern, they are easy to recognize.
In this guide, you’ll learn what an Ethereum address is, its types, how to find an ETH address, and the safest way to use it.
An Ethereum address is like an account number on the blockchain. It shows where to send or receive ETH and tokens built on Ethereum. Each address is unique, made up of 42 characters. It always begins with 0x, followed by a mix of numbers and letters.
For example:
These examples represent the standard Ethereum address format. The characters may look random, but the blockchain uses them to confirm and process transactions securely.
Ethereum addresses are not case sensitive. You can use all lowercase or a mixed version without changing the destination. Some wallets show a “checksummed” version with uppercase letters to make it easier to spot typing mistakes. Both lowercase and checksummed versions point to the same address.
Unlike Bitcoin, Ethereum does not use different legacy formats. Every ETH address follows one consistent structure: 0x + 40 characters. This makes it simple to recognize and reduces the chance of confusion with other blockchains.
Always verify that the address starts with 0x and matches your intended recipient. Sending coins to the wrong address means permanent loss.
Ethereum addresses all follow the same structure: 42 characters starting with 0x. The difference lies in how they are displayed by wallets or explorers. Here are the main formats you should know.
The standard format uses only lowercase letters and numbers. It is accepted everywhere and works without issues. Example:
0xa7d9ddbe1f17865597fbd27ec712455208b6b76d
This version is easy to copy and paste, but offers no protection against typos.
The checksummed format, introduced in EIP-55, mixes uppercase and lowercase letters. The pattern is based on the Keccak-256 hash of the address. Example (same address as above, but in checksummed form):
0xa7d9dDbE1f17865597Fbd27Ec712455208b6b76D
This style helps detect mistakes. If you change a letter incorrectly, many wallets will flag the error before you send funds.
Both versions point to the same Ethereum address, but the checksummed one adds an extra layer of safety.
Some addresses belong to smart contracts rather than individual wallets. They look the same but represent deployed code on the blockchain. Example:
0x89d24A6b4CcB1B6fAA2625fE562bDD9a23260359
Always confirm contract addresses from official sources before interacting with them. A wrong address can cause permanent loss.
If you’re just starting with Ethereum, the first step is knowing how to find your ETH address. Don’t worry — it’s much easier than it looks.
Open your crypto wallet app or browser extension and select Ethereum (ETH) from the list of coins. Look for the option that says “Receive”. Once you tap it, your ETH address will appear (you can easily copy it).
Most wallets also give you a QR code version of the same address. This is handy if you want to receive coins quickly without copying and pasting.
Never type the address by hand. Copy and paste it directly from your Ethereum wallet to avoid mistakes.
Now you know exactly how to find your ETH address and share it with others when you want to receive funds.
Using your ETH address is simple, but safety always comes first. Crypto transfers are irreversible, so one mistake can mean losing your funds. Follow these tips to stay secure:
