How to Set Up an Ethereum Wallet: A Step-by-Step Guide

An Ethereum wallet takes about ten minutes to set up and costs nothing. You create a recovery phrase, which generates a 0x address, then you send a small amount of ETH to that address to pay for transactions. The setup is the easy part. The mistakes that lose people money are specific to how Ethereum works, so this guide spends most of its time on those.

If you want a general overview of wallet types first, read how to set up a crypto wallet. If you already know you want MetaMask, the MetaMask setup guide goes through its screens in detail.

Risk warning: Self-custody means nobody can reverse a transaction or recover your funds if you lose your recovery phrase. Crypto is volatile and DeFi is experimental. Never put in more than you can afford to lose.

What an Ethereum wallet actually is

Your ETH is not stored in the wallet. It sits on the Ethereum blockchain, recorded against your address. The wallet holds the private key that proves the address is yours, and it uses that key to sign transactions.

Three things are worth keeping apart:

• Recovery phrase: usually 12 or 24 words. It can regenerate your private keys on any compatible wallet. Whoever has it controls your funds.
• Private key: the key for one address, derived from the phrase. You rarely need to see it.
• Address: your public receiving address. It is safe to share, and it starts with 0x followed by 40 letters and numbers.

Which type of Ethereum wallet to choose

A sensible starting point is a browser or mobile wallet for learning, with a small balance in it. Add a hardware wallet if the amount grows to a level you would hate to lose. Our DeFi security guide covers how to split funds between wallets.

How to set up an Ethereum wallet, step by step

Step 1: Install from the official source

Type the wallet's address into your browser yourself, or follow the link from ethereum.org's wallet finder. Do not use a search ad or a link from social media, as fake wallet apps are a common way to steal recovery phrases.

Step 2: Create a new wallet

Choose the option to create a new wallet, not to import one. You will set a password. That password only unlocks the app on this device, so it is not a backup and cannot restore your funds elsewhere.

Step 3: Write down the recovery phrase

Write the words on paper, in order, and check the spelling. Do not photograph it or save it in a notes app, email or cloud storage. Keep it somewhere private, and consider a second copy in a separate location.

No genuine wallet, support agent or website will ever ask for this phrase. Anyone who does is trying to take your money.

Step 4: Confirm the phrase and find your address

The wallet will ask you to confirm some of the words. Once that is done, you will see your 0x address. Copy it using the wallet's copy button rather than typing it.

Your wallet is now live on Ethereum. You did not need to register, and no transaction was needed to create it.

Step 5: Get some ETH for gas

Every Ethereum transaction is paid for in ETH, even if you are only moving another token such as USDC. A wallet holding tokens but no ETH cannot move them.

In practice you buy ETH on a regulated exchange and withdraw it to your address. In the UK, check the provider on the FCA's register first. We do not recommend particular exchanges, and our editorial policy explains why.

Step 6: Send a small test transaction

Withdraw a small amount first and wait for it to arrive. Then, to prove you can spend from the wallet as well as receive, send a small amount back to a different address of your own. Only move the rest after both have worked.

Step 7: Restore it to prove your backup works

This step is the one most guides skip. If you are only holding a test amount, it is the cheapest time to find out your backup is wrong. Most wallets let you add or import a wallet using a recovery phrase, so you can check the phrase produces the same address on a second device or a second wallet app. Enter it only into genuine wallet software, never into a website.

Ethereum details that catch beginners out

One address works across many networks

Your 0x address is the same on Ethereum and on compatible networks such as Arbitrum, Base, Optimism and Polygon. That is convenient, but it does not mean your balance is shared. ETH on Base and ETH on Ethereum are separate balances, even at the same address.

Sending on the wrong network is one of the most common beginner problems. If an exchange asks which network to withdraw on, it must match where you want the funds to arrive. If your balance looks empty after a withdrawal, check your wallet's network selector before you panic.

Smart contract wallets are an exception. A multisig such as Safe may have a different address on each network, and may not exist at all on a network where it has not been deployed. Check before sending to one.

Gas fees are paid to the network

Gas is the fee for processing your transaction, and it is paid to the network rather than your wallet provider. The price rises when the network is busy. A failed transaction can still cost gas, because the network did the work of trying it.

For small amounts, a lower-fee network such as Arbitrum or Base is usually a better place to learn. Keep a small amount of ETH on any network you use, because that is where the fee is paid from.

Connecting is not the same as approving

Connecting a wallet to an app only shares your public address. The danger comes from what you sign afterwards.

Using a token in DeFi usually needs a token approval, which gives a smart contract permission to move that token from your wallet. Approvals stay active until you revoke them, and a malicious one can drain that token later without any further signature from you. Read what your wallet is asking you to sign, and review old approvals using a tool such as revoke.cash.

Since Ethereum's Pectra upgrade in May 2025, a wallet account can also be pointed at smart contract code by signing an authorisation. It has legitimate uses, but it is another reason not to sign anything you do not understand.

Mistakes to avoid

• Saving the recovery phrase digitally. Malware looks for seed phrases in screenshots and notes.
• Holding tokens with no ETH. You cannot move them until you add gas.
• Copying an address from your transaction history. Scammers send tiny transfers from lookalike addresses, hoping you will paste the wrong one. Check the full address each time.
• Skipping the test send. A small test costs little. A wrong address cannot be reversed.
• Typing your phrase into a website. Any "wallet sync" or "validation" page asking for it is a scam.

Frequently asked questions

Is an Ethereum wallet free? Yes. Creating one costs nothing, and you pay only network gas fees when you send a transaction.

Do I need ID to set one up? No. A self-custody wallet needs no account or identity check. Exchanges where you buy ETH do require identity checks.

Can I use one wallet for all Ethereum tokens? Yes. ERC-20 tokens and NFTs on Ethereum all sit at your same 0x address. A token may need adding to the wallet before it displays, but it is there either way.

Can I use the same phrase in a different wallet? Usually, yes. Most Ethereum wallets follow the same standards, so a phrase from one can restore the same address in another. If the address does not match, the wallet may be using a different derivation path, so check its documentation before assuming funds are lost.

What happens if I lose my phone? You can restore the wallet on another device with your recovery phrase. Without the phrase, the funds cannot be recovered by anyone.
