MetaMask to launch self-custody crypto card with Mastercard

Wallet provider MetaMask is launching a crypto payments card that will allow users to spend self-custodied funds, offering crypto holders additional ways to use their tokens.

The new card is backed by Mastercard and is being developed in partnership with CompoSecure and Baanx, according to the company. The product uses smart contracts to execute the IRL (In Real Life) transactions, with a processing speed under five seconds. It operates on the Linea network, a layer-2 scaling solution on Ethereum.

The companies marketed the self-custodied crypto card as an alternative to the potential risks associated with centralized exchanges. In February, the second-largest crypto exchange by volume, Bybit, was hacked for $1.4 billion, an event that sparked widespread consternation in the crypto space.

With the launch of its card, MetaMask is entering a competitive segment of the cryptocurrency market. Major exchanges like Binance, Bybit, Coinbase, and Crypto.com already offer crypto debit cards, some of which feature "crypto-back" rewards that allow users to earn digital assets on their purchases.

MetaMask has struggled lately as interest in and participation in the Ethereum ecosystem have dried up. According to Dune Analytics, the wallet collected just $289,312 in fees for the week of April 14, much less than the $1.3 million in fees collected for the same period a year ago.

Luxury brands like Dorsia have begun accepting various cryptocurrencies as payment, while messaging app Signal is reportedly exploring adopting Bitcoin for peer-to-peer transactions, and a bill in New York has been introduced to legalize the use of Bitcoin and other cryptocurrencies for state payments.
