MetaMask Setup Guide for Beginners (2026)

MetaMask is the most widely used Ethereum wallet and your gateway to tokens, DeFi and creating your own ERC-20. It's a non-custodial wallet, which means you — not a company — control your funds. That power comes with responsibility, so this guide walks you through setting up MetaMask correctly and safely, from installation to your first transaction, with the security habits that protect you from day one.

What MetaMask is

MetaMask is a non-custodial crypto wallet available as a browser extension and a mobile app. "Non-custodial" means your private keys live on your device and only you can authorise transactions — there's no company holding your funds and no password reset. It lets you store ETH and ERC-20 tokens, connect to decentralized apps, swap, and sign the transactions that power everything on Ethereum.

Step 1 — Install from the official source

Only ever install MetaMask from the official website, metamask.io, or your device's official app store. Fake MetaMask extensions and apps exist specifically to steal seed phrases. From metamask.io you'll be directed to the correct extension for Chrome, Firefox, Brave or Edge, or the iOS/Android app. After installing the browser extension, pin it to your toolbar for easy access.

Step 2 — Create a new wallet

Open MetaMask and choose "Create a new wallet." You'll set a password — note that this password only unlocks the app on this device; it is not your account recovery. The real key is the secret recovery phrase you're about to receive. If you already have a wallet elsewhere, you can instead choose "Import" and enter your existing recovery phrase.

Step 3 — Secure your secret recovery phrase

MetaMask shows you a 12-word secret recovery phrase. This is the master key to your wallet. Anyone who has these words controls your funds, and if you lose them with no backup, your funds are gone forever — there is no support line that can recover them. Treat it accordingly:

• Write it on paper (or stamp it into metal) and store it somewhere safe and private. Consider two copies in separate locations.
• Never store it digitally in a screenshot, photo, cloud note, email or password manager that syncs online.
• Never type it into any website. No legitimate app or person will ever ask for it. Every request for your seed phrase is a scam.

MetaMask will ask you to confirm a few words to prove you saved it. Do this carefully.

Step 4 — Understand accounts and networks

Your wallet can hold multiple accounts (each with its own address) derived from the same recovery phrase. At the top of MetaMask you'll also see the network selector. By default you're on Ethereum Mainnet — the main network where real ETH and tokens live. You can add other EVM networks later, but for using and creating ERC-20 tokens, Ethereum Mainnet is what you want.

Step 5 — Fund your wallet with ETH

To do anything beyond receiving assets, you need some ETH to pay gas. Copy your address (click your account name to copy it) and send ETH to it from an exchange like Coinbase or Binance, or buy directly inside MetaMask. Double-check you're sending on the Ethereum network and that the address matches exactly. Start with a modest amount that comfortably covers your planned activity plus gas.

Step 6 — Connect to a dapp

To use a decentralized app — a DEX, an NFT site, or a token creator — you click its "Connect Wallet" button and approve the connection in MetaMask. Connecting is read-only: it lets the site see your address and propose transactions, but it can't move anything without you signing. Always confirm you're on the genuine site before connecting, and disconnect from sites you no longer use.

Step 7 — Add and view tokens

ERC-20 tokens don't always appear automatically. To see a specific token, you paste its contract address into MetaMask's "Import tokens" screen, and your balance appears. We cover this fully in add your token to MetaMask. Remember that importing a token is just telling your wallet to display a balance it already holds — it doesn't cost gas.

Step 8 — Send and receive

To receive, share your address (or its QR code). To send, click "Send," paste the recipient address, choose the asset and amount, review the gas fee, and confirm. Always double-check the first and last characters of the address and consider sending a tiny test amount first for large transfers. Transactions are irreversible once confirmed.

Understanding gas in MetaMask

When you confirm a transaction, MetaMask shows an estimated gas fee in ETH. You can usually pick a speed — slower is cheaper. Gas fluctuates with network demand, so for non-urgent actions, waiting for a quieter time saves money. See our Ethereum gas fees explained guide for the full picture.

Security best practices

MetaMask's security is mostly about your habits. Build these from the start:

• Guard your seed phrase as described above — it's the only thing that truly matters.
• Beware phishing. Bookmark official sites; ignore "support" DMs; never approve a transaction you didn't initiate.
• Review token approvals. Revoke allowances you no longer need using Etherscan's approval checker.
• Use a hardware wallet (Ledger or Trezor) for significant funds — it keeps your keys offline while still working through MetaMask.
• Consider a separate "burner" account for risky or experimental interactions, kept apart from your main holdings.

Common issues and fixes

• "I don't see my token." Import it by contract address; it isn't lost, just not displayed.
• "Transaction stuck/pending." Gas price may be too low; you can speed it up or cancel from the activity tab.
• "Wrong network." Switch the network selector to Ethereum Mainnet (or the network the asset lives on).
• "Insufficient funds for gas." You need more ETH; the token itself can't pay gas.

Using MetaMask to create a token

Once MetaMask is set up and funded, you're ready to launch your own ERC-20. Open Create ERC-20 Token, connect MetaMask, fill in your token details, and approve the single deployment transaction. The full supply is minted to your MetaMask address. Our creation guide walks through every field.

Conclusion

Setting up MetaMask takes only a few minutes: install from the official source, create a wallet, and — above all — back up your secret recovery phrase offline and never share it. Fund it with a little ETH for gas, learn to connect to dapps and import tokens, and adopt good security habits early. With that foundation in place, you can safely hold tokens, use DeFi, and create your own ERC-20 whenever you're ready.
