MetaMask and Mastercard Launch Ethereum-Powered Crypto Payments Card

MetaMask has taken a significant step into the crypto payments arena by introducing a self-custody payment card backed by Mastercard. Developed in collaboration with CompoSecure and Baanx, this metal card enables users to spend directly from their MetaMask wallets, eliminating the need for centralized exchanges. The card utilizes Linea, an Ethereum layer-2 solution, to facilitate near-instant transactions (under five seconds) via smart contracts. This innovation marks a major milestone in bridging decentralized finance (DeFi) with everyday spending, further solidifying Ethereum’s role in mainstream financial adoption. As of April 2025, this development underscores the growing convergence of traditional finance and blockchain technology, offering users greater control and efficiency in their crypto transactions.

MetaMask Launches Crypto Payments Card Backed by Mastercard

MetaMask is making a bold move into the crypto payments space with a new self-custody card powered by Mastercard. Developed in partnership with CompoSecure and Baanx, the metal payment card allows users to spend directly from their MetaMask wallets, bypassing centralized exchanges.

The card leverages Linea, an Ethereum layer-2 solution, enabling real-world transactions in under five seconds through smart contracts. This innovation arrives amid growing security concerns following February’s $1.4 billion Bybit hack, positioning MetaMask as a safer alternative for crypto transactions.

U.S. Court Overturns Tornado Cash Sanctions in Win for Crypto Privacy

A federal court has reversed its earlier decision supporting the Treasury Department’s sanctions against cryptocurrency mixer Tornado Cash, dealing a blow to regulatory overreach. The ruling prohibits OFAC from reimposing restrictions on the privacy tool, marking a significant victory for digital asset advocates.

Coinbase Chief Legal Officer Paul Grewal celebrated the decision on social media, praising plaintiffs for challenging government overreach. "Congratulations to the brave plaintiffs who had the courage to stand up to their own government for their rights under law," Grewal stated, highlighting the protracted legal battle that included multiple government attempts to delay judgment.

Ethereum Developers Propose New Fee Model to Support Diverse Projects

Ethereum developers are advancing a novel fee structure designed to enhance the platform’s long-term viability. The proposal introduces a square root-based calculation to scale fees proportionally with project size—smaller initiatives face higher relative costs, while large-scale operations benefit from a 1% cap.

A $170,000 project would incur approximately 7% in fees under this system. This tiered approach emerges as a direct response to evolving market demands, seeking equilibrium between sustaining network infrastructure and fostering ecosystem growth.

Ethereum Holds Steady Above $1,800 Amid Strategic Pivot in Development Focus

Ethereum demonstrates resilience as ETH/USD maintains its footing above the $1,800 threshold, marking a 30% recovery from April’s lows NEAR $1,386. Despite remaining 45% below its all-time high, the asset shows stability in volatile market conditions.

The Ethereum Foundation has recalibrated its roadmap, shelving the contentious EOF upgrade in favor of prioritizing PeerDAS scaling solutions. This strategic shift coincides with a leadership restructuring aimed at accelerating Layer 1 and Layer 2 scaling initiatives while enhancing user experience over the coming year.

Market participants are eyeing potential catalysts including the May 7 Pectra upgrade and macroeconomic developments that could shape Ethereum’s price trajectory. The removal of EOF from the Fusaka roadmap signals a pragmatic approach to network evolution, with developers concentrating on near-term scalability improvements.
