Digital asset wallet MetaMask is collaborating with Mastercard and Web3 payment financial company Baanx to launch a blockchain-based debit card. The initial batch is limited to only thousands of European and UK users for testing. This card allows users to directly use their $USDC, $USDT, and wETH assets stored on the Linea blockchain (an Ethereum Layer 2 network) for payments. It is reported that this debit card will be fully rolled out in the EU and UK later this year, with plans to gradually introduce it in other regions.
