Ether.fi proposes replacing EtherFi Cash backend with Aave V4

Ethereum restaking protocol Ether.fi has proposed adopting Aave V4 infrastructure on Optimism to enhance the financial backend of its crypto credit card, EtherFi Cash. The proposal suggests replacing the card's current Debt Manager system, which handles credit and lending, with Aave's V4 lending infrastructure, as operating its own engine has become a burden. In exchange for providing the V4 deployment source code and an operating license, Aave would receive 20% of the Reserve Factor Income. The stablecoin GHO will be added as the primary borrowable asset in this market. It could also be integrated for direct payments and deposits on the EtherFi Cash card in the future, subject to the Aave DAO's approval. EtherFi Cash is a physical card that enables Visa payments by allowing users to borrow stablecoins against their deposited interest-bearing assets.
