EtherFi, a well-known liquid restaking protocol, has partnered with Scroll, a zero-knowledge rollup network, to launch a new blockchain-based credit card named 'Cash'. The card will be issued as a Visa card and will utilize Scroll's layer-2 network as its settlement layer. The 'Cash' card will offer up to 8% cash back on all transactions, making it the highest cash back credit card globally. Additionally, the card will allow users to borrow money against their crypto collateral and enable gasless transactions. EtherFi's CEO, Mike Silagadze, stated that the initiative aims to make decentralized finance more accessible to the general public. The card will also reward 3% cash-back on all transactions.
