When talking about cryptocurrency payments, one term often comes up: Metamask . But what exactly is it, and why is its role central to the adoption of Web3 payments?

Metamask, the world's most widely used non-custodial wallet

Metamask is a non-custodial digital wallet, created by Consensys, a Web3 pioneer.

This means that the user retains full control of their funds and private keys , unlike a so-called custodial wallet.

👉 Custodial wallet : Your funds are managed by a third party (e.g., a centralized exchange like Binance or Coinbase). The advantage: ease of use. The disadvantage: You don't actually hold your cryptos, since the operator has custody of them.

👉 Non-custodial or self-hosted wallet : Your cryptocurrencies are stored directly in your digital wallet, and you are the only one who owns the private keys. In other words, “Not your keys, not your coins” : your assets truly belong to you.

Why is Metamask essential for crypto payments?

With over 30 million active users , Metamask has become the go-to wallet for interacting with the blockchain. Available as a browser extension and mobile app, it allows:

• to store your cryptos independently,
  
  
• to interact with thousands of decentralized applications (dApps),
  
  
• and now… to pay directly to partner merchants thanks to solutions like Lyzi .

How does a payment work with Metamask and Lyzi?

Once on the payment page, you have several options to choose from.

There are exchanges like Binance or WhiteBIT, but also the Wallets option, which represents non-custodial wallets.

‍

‍

‍

‍

This way, you're connected and your address is saved. You'll benefit from various rewards like cashback linked to your purchases, or even community drops.

‍

‍

Once you select the 'Wallets' option, you will be able to choose the network and crypto you wish to use and therefore spend.

Here we have chosen to use the Sepolia Ethereum network (test), and to spend USDC.

‍

You are then offered to pay either by sending the funds (exact amount) to the address, manually. Or in 1 click, that is to say by validating the transaction from your Metamask, already connected. This method is more suitable for payment on desktop computer because on mobile it requires a certain agility. Indeed, you will have to switch from the wallet to the Dapp to validate the authorizations in the wallet.

‍

‍

As mentioned above, you must validate the transaction from your wallet. (Make sure you have enough money to pay the gas fees 🙂)

‍

‍

The transaction moves to the confirmation state…

‍

‍

And there you have it! The payment is validated! 😀

‍

‍

Your payment is now complete, and the merchant will receive the funds (in euros) directly into their account within 24 to 72 hours! You can enter your email address to receive your receipt and even take a look at the loyalty program.
