Regional availability

While we want to make MetaMask's features accessible to as many people around the world as possible, buying crypto in MetaMask (also referred to as on-ramp) is not available in every country or region.

This is because the companies we partner with cannot operate in every jurisdiction, as their operations are affected by varying laws and regulations.

When you buy crypto in MetaMask, we will automatically show you your options based on what region or country you are in.

I can't buy crypto in my country/region.

If your country/region isn't supported, you may still be able to get tokens into your wallet through other means.

1. One route, for example, could be to buy tokens on a centralized exchange (CEX) and deposit them into MetaMask. See our guide for more information. Also, bear in mind that this route, like on-ramps themselves, will usually require KYC (know your customer) steps, such as proving your identity, and availability may also vary by region. CEXs also differ from MetaMask in that they are custodial — meaning you don't have control of your accounts' private keys.

2. You could also arrange a P2P (peer-to-peer) deposit into your wallet by sending simple transactions.

Regardless of the method you choose, please do your own research before handing over any money, and make sure the platform you're using is safe. Always practise good web3 security habits.

How to buy crypto

How buying crypto works

Buying crypto in MetaMask involves using an aggregator of on-ramp providers, making the process accessible, fast, and scalable.

When you enter how much of a token you want to buy, MetaMask's integrations with our vetted providers will spring into life, and fetch you quotes from each. These quotes automatically refresh every 10 seconds to account for gas price fluctuations, minimizing the potential for failed transactions (if gas prices rise after submitting the transaction, your quoted total may be too low to cover transaction costs by the time the transaction is picked up by the network).

Since you input your region and currency during the process, the quotes you're presented with are automatically configured for your circumstances: so no need to worry about whether you'll be able to use the available payment methods in your region, or whether your region is supported by that provider. If it appears on the quote list, you will be able to buy as quoted. Easy.

• Extension and Portfolio
• Mobile

In Extension, click 'Buy & Sell' to be taken to MetaMask Portfolio.

On MetaMask Portfolio, once you select your region and your payment method, you'll move through the Buy flow in one screen, where you can input your amount, adjust the payment method (if you wish to do so), and select your quote.

On the mobile app, click the wallet actions button in the center of the tab bar. This will bring up a pop-up menu, where you can select the 'Buy' button.

note

**Vous ne pouvez pas accéder à la fonction d'achat de MetaMask Portfolio à partir d'un appareil mobile.**Pour cette raison, assurez-vous d'aller directement à la fonction d'achat in-app, plutôt que d'essayer d'acheter à partir de portfolio.metamask.io.

1. Rendez-vous sur la page d'accueil de votre portefeuille et trouvez le bouton : sur Extension, vous pouvez trouver le bouton « Acheter/Vendre » sur la gauche de la vue de votre portefeuille, qui vous redirigera vers le Portefeuille MetaMask. If you're on MetaMask Portfolio already, select the 'Move Crypto' tab, and then click 'Buy'.

2. If you're a first-time user, you must select your region, which will generally default to your current location. Si vous avez déjà utilisé cette fonction, MetaMask enregistrera la région que vous avez sélectionnée la dernière fois.

Dans le menu déroulant, recherchez ou faites défiler jusqu'à ce que vous trouviez le pays où votre méthode de paiement (carte/compte bancaire) est enregistrée. Les utilisateurs américains pourront alors sélectionner leur état. Si votre région n'est pas couverte par au moins un de nos fournisseurs, nous vous en informerons. You can read more about other ways to purchase crypto here.

3. Sur l'écran suivant, sélectionnez votre mode de paiement (vous pouvez toujours le modifier par la suite si vous changez d'avis) :

Choisissez entre Apple Pay/Google Pay (cela s'ajustera en fonction de votre appareil), carte de débit/crédit, PayPal (États-Unis uniquement, à l'exception d'Hawaï) et virements bancaires (avec le mécanisme ajusté en fonction de votre région, des détails KYC et de la devise : par exemple, ACH pour les États-Unis, Pix pour le Brésil, et SEPA pour l'Europe ; voir ci-dessous le système britannique de paiements rapides). Assurez-vous que vous êtes à l'aise avec la durée estimée et les limites de paiement indiquées à côté de chaque option.

4. Sélectionnez le jeton que vous voulez acheter, en utilisant le menu Vous voulez acheter en haut de l'écran.

5. Saisissez le montant de votre choix, c'est-à-dire la valeur (en monnaie fiduciaire) du jeton que vous souhaitez acheter.

6. Choisissez votre devis. Après une brève attente, vous verrez apparaître les devis disponibles en fonction de vos préférences. Ils sont classés par ordre décroissant en fonction de la quantité de crypto que vous recevez, la valeur la plus élevée se trouvant en haut. Tirez vers le bas à partir du haut de l'écran pour actualiser les cotations.

Lorsque vous choisissez un fournisseur, il se peut que vous deviez remplir le formulaire KYC si vous n'avez jamais utilisé ses services auparavant.

Once your order is complete, you will see the below screen:

Résolution de problèmes

What do I do if my transaction fails?

Since MetaMask does not execute your transaction, the provider will likely be better placed to support than our team. In these situations, we recommend you contact their support teams first.

For any issues you encounter with MetaMask itself (such as problems selecting your region or currency, or with the buying process), get in touch with MetaMask Support via the 'start a Conversation' button on the Support page.

If you're facing problems using a provider's platform, such as payment limits, payment methods, or KYC, we recommend you get in touch with their support teams directly.

Why is my transaction still pending?

To get your ordered crypto into your MetaMask wallet, the provider you choose must execute transactions on-chain. This means that, as a minimum, you will need to wait as long as it takes for the transactions to be processed by the network (block time).

Once you submit your request, you can see the pending transaction in your MetaMask activity.

If your bank account was charged and there are delays in receiving your crypto, we recommend you contact the provider's support team directly. Pending purchases (not yet confirmed on the blockchain) are usually caused by the on-ramp provider's pre-authorization processes.
