Setting up the MetaMask Card is three jobs in a row: install the wallet, open a card account, then choose the token that pays. Crypto Explorer published a walkthrough on November 19, 2025, and I would follow his order, because most of the mistakes happen when people skip ahead to the funding step. Much of the setup is an ordinary on-chain approval, and that approval is what decides how far the card can reach into your wallet.
What the MetaMask Card is and who stands behind it
The MetaMask Card is a payment card tied to a MetaMask wallet instead of a bank balance. You connect a wallet account to a separate card account, choose which token pays for your purchases, and the card spends from there. The entry point is the Card tab in the MetaMask portfolio dashboard, which you open from the browser extension or, on a phone, from the portfolio button in the app.
The card account is not the wallet account. Even if you already use MetaMask, signup means creating a new account with an email address, a phone number and a password, and trying to log in with existing wallet credentials at that screen gets you nowhere. The creator warns about this before the form opens, and it is the first place a beginner can lose ten minutes.
Signup also asks whether you are an international or a US user, which is how the flow splits regions. The last screen before the card is issued asks you to tick a box confirming you have read the Card Issuer Terms & Conditions, a separate agreement from MetaMask's own terms and the one that governs the card side of the arrangement.
Three networks work with the card: Linea, Base and Solana. Picking one connects a wallet account on that network to the card, and the choice decides which tokens are easy to fund with and what a transaction costs. The screen lets you change the network later, and funds can be moved from one chain to another if you start on the wrong one.
What you need before you start
Six things, and only the last one costs anything: the MetaMask extension, a seed phrase written on paper, an email address, a phone number, a government ID and a small amount of ETH for gas fees.
A seed phrase is the master key to a wallet. Anyone who reads the words can move everything the wallet holds, which is why the creator is blunt about where it goes: paper, kept somewhere safe, never a note on your phone or a photo in your gallery. "Don't take a picture of it, okay, because there's malware out there which can scan through all of those things and they can drain your funds."
The identity check is run by Veriff, a third-party verification company, and it accepts a passport, an ID card, a driver's license or a residence permit. You photograph the front and back of the document, take a selfie, then confirm your physical residence and personal details. KYC, short for know your customer, is the identity screening regulated financial products run before they let anyone move money, so expect to hand over a real document rather than a username.
ETH covers gas, the fee a network charges to process a transaction. On Linea, the creator measured it at around one cent. If you claim the free ETH offered to new users, you may not need to buy any before your first payment.
Setting up the MetaMask Card, step by step
The order matters. Two of these steps cost gas and the rest are forms.
- Install the MetaMask extension from the Chrome Web Store and finish the setup, writing the seed phrase on paper and storing it offline.
- Open the extension and click Explore web3 to reach the MetaMask portfolio dashboard.
- Select the Card tab in the left menu. On mobile, tap the portfolio button in the app and you land on the same screen.
- Click Get Started, choose international or US, then click Create an account.
- Enter your email, phone number and password, then type the confirmation codes sent to your email and to your phone.
- Complete the Veriff check with a passport, ID card, driver's license or residence permit, photographing both sides and taking a selfie.
- Review your details, add your physical residence, tick the box for the Card Issuer Terms & Conditions and click Confirm your details.
- Pick Linea, Base or Solana, then click Continue with your choice.
- Connect the MetaMask account the card should spend from in the pop-up.
- Claim the free ETH if it is offered. That ETH covers gas on Linea, and the creator expects the same offer to arrive in SOL if you chose Solana.
- Choose the token that funds payments, then either approve card spending or set a custom limit, and confirm the approval in MetaMask.
- Click View card overview, flip the card with the toggle to read the card number and CVC, and add it to Apple Wallet or Google Wallet with the five-step instructions on screen.
Step 11 is the one to read twice. The approval is a transaction, not a preference, and it is where the card gets permission to spend from the wallet.
How the spending approval works and what the gas costs
The dashboard offers two ways to set the card loose. "Approve card spending" means the card keeps working as long as tokens sit in the wallet, with no ceiling in the way. A custom spending limit caps how much the card can take, and you can raise or lower it later.
The creator's advice is to use the limit if you are concerned about safety and security, and I would take that advice for a first card. A token approval is a standard piece of how crypto apps work: the wallet signs a transaction letting a contract move up to a set amount of a token. A cap you can live with keeps a mistake or a leaked card number from reaching the whole balance.
It also keeps the money where it started. The balance stays in the wallet you connected, and the card reaches it through the approval you signed. The dashboard's list of funding sources shows those balances, lets you add to them and sets the order the card draws from them.
Both routes cost a gas fee, because both are transactions. The same applies when you change the limit afterwards: back to the dashboard, another gas payment, then the new figure takes effect. On Linea the fee was around one cent, paid in ETH, and the creator demonstrated a 1,000 unit cap on a euro stablecoin and confirmed it in the MetaMask pop-up.
That small number makes a generous limit cheap to adjust, and it makes constant fiddling with a tiny limit mildly annoying. I would set the limit once, near what I plan to spend in a month, and leave it.
Choosing between Linea, Base and Solana
Linea, Base and Solana all work with the card, and the creator suggests starting on the network where your funds already sit. If the wallet is empty, the choice can wait: funds can be moved across chains later, and the network can be switched on the spending screen.
Gas is paid in the network's own token. Linea and Base use ETH, Solana uses SOL, which is why the free claim changes shape with the network you pick. In the creator's case the claim delivered 19 cents of ETH, and he expected that to cover plenty of transactions.
Rewards were the one practical difference between the networks, and the program ran on Linea. It had two parts: an Aave boosted yield for USDC deposited through the same MetaMask account, and a community cashback. Aave is a lending protocol, and the pitch is that depositing USDC there with the card's account earns more than the standard rate. The creator recommended Linea to beginners for that reason. Base and Solana did the same job for payments, with no equivalent program running at the time.
Which token pays for your spending
The spending screen lists a set of tokens, and the choice decides what the card moves each time you pay. Only two dollar tokens, USDC and mUSD, sit on the main screen; the rest are behind a More button, which is why the list below is longer than what a first-time user sees.
| Token | What you get |
|---|---|
| USDC | Dollar-pegged stablecoin, one of the two options offered on the spending screen |
| mUSD | Dollar-pegged stablecoin, and the token cashback is paid in |
| USDT | Dollar stablecoin, suggested for spending in the US |
| WETH | Wrapped Ethereum, more in fees and a tax wrinkle the creator warns about |
| EUR e | Euro stablecoin for spending in euro countries |
| GBPe | Pound stablecoin for spending in the UK |
| aUSDC | Aave deposit token that keeps earning yield until it is spent |
A stablecoin is a token designed to hold a steady value against a currency, usually the dollar, which is why it suits everyday payments. The travel rule is simple enough. Going to the US, pick a dollar token. Going to the UK, pick GBPe. Living in the eurozone, pick EUR e. Matching the token to the currency you spend in keeps conversions out of the way, which the creator frames as the way to pay the lowest fees.
Wrapped Ethereum is the exception to his advice. It is ETH in a form other contracts accept, and its price moves, so the amount you have available changes between payday and purchase. He also says it can cost more in fees and may have a tax impact. Spending crypto can count as a taxable sale in many countries, so a token whose value moves adds a second layer of record keeping to every coffee. I would keep one stablecoin enabled for everyday spending and leave wrapped Ethereum alone until the tax side makes sense to me.
aUSDC is the more interesting option. It is a token for USDC deposited on Aave, a lending protocol, and it keeps earning yield right up to the moment the card spends it. The card taps into the deposited aUSDC automatically through smart contracts. That is convenient, and it also means the money sits inside a lending market rather than idle in a wallet, which brings the usual risks of a lending protocol with it.
Cashback, credits and the weekly claim
Cashback comes in mUSD on the free tier at 1% of on-chain spend. The metal card, which the dashboard lists as a waitlist, was quoted at 3%. Both figures come from the creator and both can change, so treat them as the terms at the time of recording rather than a fixed return.
The claim is manual, and this is the part people get wrong. Cashback accumulates in the dashboard, and you have to go and collect it. The creator is direct about the consequence: "If you do not claim it on a weekly basis, you might lose it, so be very active when it comes to that." I would put a reminder in my calendar the day the card arrives, before the first purchase.
The same screen handles refunds. If a merchant reverses a payment, the money lands under Credits, and a credit balance is used first as a funding source for later payments, so it decides which token gets spent next.
Managing the card and moving money into the wallet
The card overview holds the controls you will actually use. A toggle flips the card over to show the card number and the CVC, the security code online checkouts ask for. The same screen lists funding sources, the spending cap, and the order in which the card draws from each source.
The Manage tab adds a few more:
| Option | What it does |
|---|---|
| Metal Card Waitlist | Where the physical metal card is requested |
| Freeze Card | Stops the card from being used |
| Card replacement | Requests a new card |
| Statement of Transactions | Exports your card transaction history |
Freezing the card is the first thing I would reach for if a card number leaked or a phone went missing, since it does not depend on moving funds.
Getting money into the wallet is a separate job from managing the card. The extension dashboard has four buttons: Buy, Swap, Send and Receive. Buy takes a bank card and delivers crypto straight into the wallet. Receive opens a screen where you pick the network the card uses, then copy the address or show the QR code and send from another wallet or an exchange. The creator's advice for a beginner is to send the same token you plan to spend, plus a little ETH for gas on Linea.
Risks to weigh, and what to check before your first payment
The tax point from the token section covers everything on the list, not just wrapped Ethereum. Any gain since you acquired the token may be taxable, and while stablecoins move little, the records still matter.
Then there is the approval. A card with no cap can spend whatever sits in the connected account, and a leaked card number plus a large balance is a bad combination. The limit exists for that reason.
Cashback that must be claimed weekly is another small risk: it disappears if you forget. Rewards programs at the network level can change their terms, and yield earned through a lending protocol depends on that protocol working as intended.
Issuing, monthly, top-up, currency conversion and ATM fees are the gap, so read the Card Issuer Terms and the current fee schedule before you rely on the card for daily spending.
Before the first payment I would do four small things. Type the site address yourself or use a bookmark rather than a link from a message, because the card dashboard sits behind a login. Set a limit close to your monthly spending and fund it with a stablecoin you understand. Keep a little ETH for gas. Then make one small purchase before you move a month's money into the wallet, and if the cashback claim is part of why you signed up, put a weekly reminder in your calendar now, while the setup screens are still open.
