MetaMask has unveiled a new self-custody crypto payment card, developed in collaboration with Mastercard, CompoSecure, and Baanx. This metal card enables users to spend cryptocurrency directly from their MetaMask wallets without relying on centralized exchanges.
Operating on the Linea network—an Ethereum Layer-2 scaling solution—the card processes real-world transactions in under five seconds using smart contracts. This approach significantly reduces both transaction times and costs.
The introduction of this card arrives amid growing concerns around exchange security, highlighted by high-profile incidents such as the $1.4 billion loss suffered by Bybit in February. MetaMask’s self-custody model offers users greater control over their assets, reducing exposure to exchange-related risks.
How the MetaMask Payment Card Works
The card integrates directly with the MetaMask wallet, allowing seamless conversion of crypto into fiat currency at the point of sale. Users maintain full control of their private keys throughout the transaction process, reinforcing the self-custody principle.
Unlike traditional crypto debit cards offered by platforms like Binance or Coinbase, the MetaMask card does not require users to pre-load funds onto a centralized platform. This eliminates intermediary custody and enhances security.
Transactions are settled on the Linea blockchain, which helps keep gas fees low and confirmation times short. This makes the card suitable for everyday purchases, from retail to online services.

Competitive Landscape and Market Context
MetaMask now competes with established players like Crypto.com, Binance, and Bybit, each of which offers its own version of a crypto debit card. Many of these cards also offer rewards in cryptocurrency for spending.
The launch comes at a time when Ethereum’s transaction fee revenue has seen a decline. Recent data from Dune Analytics indicated a significant drop in MetaMask’s weekly fee earnings compared to previous years.
Nevertheless, the trend toward crypto-based payments continues to gain momentum in 2025. Companies like Dorsia have integrated cryptocurrency payments, messaging app Signal is exploring Bitcoin-based P2P transactions, and the state of New York is advancing legislation to accept crypto for official transactions.
