MetaMask Expands U.S. Rollout of Blockchain-Based Debit Card Following Year-Long Pilot

The claim that MetaMask has formed a partnership with Mastercard to introduce a self-custody crypto payment card in the United States is only supported by a single moderately authoritative secondary source that refers to a 'MetaMask in partnership with Mastercard and Baanx' mention. This source appears speculative and lacks a direct link to any official statement or press release from MetaMask, Mastercard, or ConsenSys. Other moderately credible business and crypto outlets discussing Mastercard’s DeFi and stablecoin hiring efforts offer background context but do not corroborate this partnership. One reference suggesting MetaMask intends to enable payments through Mastercard merchants shows conceptual alignment with the idea but fails to confirm an actual, formal partnership or product launch. The absence of confirmation from high-authority sources such as Fortune, Yahoo Finance, or official corporate channels indicates that this partnership claim remains unverified. Therefore, while there are hints that discussions or exploratory collaborations might exist in the crypto payments space, the evidence is not robust enough to confidently assert that MetaMask and Mastercard have formally partnered to release a self-custody payment card.
