MetaMask is rolling out a rewards program for its card users, offering an enticing incentive to engage with the Linea network. This initiative, a collaboration between the popular crypto wallet, Consensys' Layer 2 network Linea, and Brevis, leverages zero-knowledge (ZK) proof technology to enhance user benefits. According to Wu Blockchain, MetaMask card users can now earn an additional 2.4% annual yield by borrowing or lending USDC on Linea through platforms like AAVE. This boost is made possible through the integration of ZK-proofs, ensuring secure and verifiable transactions. This move aims to increase activity and liquidity within the Linea ecosystem while providing MetaMask cardholders with a compelling reason to explore DeFi opportunities. The program highlights the growing trend of combining traditional financial tools with decentralized finance solutions. ```
