MetaMask, Mastercard, CompoSecure, and Baanx announced a card for direct crypto payments without manual fiat conversion, preserving self-custody
The new metal payment card is integrated with the MetaMask Portfolio and the Linea network infrastructure, enabling instant transaction processing and reduced fees.
MetaMask Card: Core Architecture and Key Features
Just today, we discussed the significant role Visa plays in blockchain integration and crypto adoption, where they arguably remain more proactive — and now, one of the largest crypto wallets announces the launch of its own card in partnership with Mastercard, as well as CompoSecure and Baanx.
From the user’s perspective, this provides the solution that enables seamless integration with the MetaMask wallet and provides the ability to spend cryptocurrency directly from non-custodial addresses. Self-custody is maintained until the moment of the transaction without the need to pre-fund separate accounts or convert assets on centralized platforms.
As Christian Rau, Senior Vice President of Fintech and Crypto at Mastercard, noted:
“Consumers are demanding greater flexibility and choice in how they spend their assets.”
From an architectural standpoint, transactions are processed through Linea, an L2 solution built on top of Ethereum, which ensures fast and low-cost transaction. Smart contracts are used in the settlement process, allowing users to avoid traditional banking intermediaries and centralized asset conversion — all while maintaining self-custody. This is complemented by integration with Baanx, which provides the infrastructure for instant transaction processing without transferring funds to deposit accounts.
Garth Howat, CEO of Baanx, emphasized:
“With the MetaMask card, users remain in control of their assets until the moment they transact.”
Thus, by being integrated into MetaMask Portfolio — the extended version of the wallet focused on digital asset management and DeFi application — the MetaMask сard enables seamless access to both TradFi and DeFi operations.
Jon Wilk, CEO of CompoSecure, the company responsible for manufacturing the metal card itself, highlighted the significance of the new product:
“The MetaMask metal payment card isn’t just another crypto card, it’s a paradigm shift.”
Conclusion
This is not the first attempt to bridge the gap between Web2 and Web3 payment systems and solutions. There are already solid applications that allow instant crypto-to-fiat conversion and vice versa, enabling users to live fully in Web3 while having a seamless gateway to Web2. Moreover, some solutions like Ka.app offer extensive integrations and capabilities with Web2 services, with familiar features of mobile banking apps, making this gap even less noticeable.
However, what stands out here is that MetaMask — one of the earliest and the most famous wallet among DeFi users — is now launching its own card in partnership with major TradFi players, directly pointing to a growing trend where crypto is seeking adoption not only as an investment tool but also for everyday usage.
Considering that Mastercard is accepted worldwide and that you can spend your crypto assets directly, even if you forget or run out of battery on the device — having a physical card linked to your crypto, which does not require manual fiat conversion or centralized intermediaries, could represent a major step forward.
