Ethereum restaking protocol Ether.fi has proposed a plan to adopt Aave V4 infrastructure on Optimism to strengthen the financial backend of its crypto credit card, Ether.fi Cash. The core of the proposal is to replace the existing Debt Manager system, which handles card credit and lending systems, with the Aave V4 lending infrastructure. Aave will receive 20% of the Reserve Factor Income in exchange for providing the V4 deployment source code and operating license. The stablecoin GHO will be added as a major lending asset in this market and may be integrated as a direct payment/deposit asset for Ether.fi Cash cards at the discretion of the Aave DAO in the future. Ether.fi Cash is a real-world asset-backed card that allows users to borrow stablecoins against their deposited interest-bearing assets to process Visa payments, and operating its own lending engine has become burdensome.
