Ether.fi, the Ethereum recovery protocol, has submitted a board proposal to replace the backend infrastructure of its crypto credit card, EtherFi Cash, with Aave V4 on the Optimism network. This move is intended to ease the operational burden of running its own lending engine and leverage Aave’s proven liquidity infrastructure.
Proposal details
The proposal, submitted to both DAOs Ether.fi and Aave, proposes replacing the current Debt Manager system – which handles lending and lending for the EtherFi Cash card – with Aave’s V4 lending protocol. Ether.fi has cited the increasing complexity and resource demands associated with operating its own lending engine as the main reason for the change. In exchange for providing the source code for the V4 implementation and an operating license, Aave would receive 20% of the reserve factor revenue generated from the market.
Aave’s stablecoin, $GHOwill be added as the main loanable asset in this new market. Future integrations could make this possible $GHO to be used for direct payments and deposits to the EtherFi Cash card, although this requires separate approval from the Aave DAO.
What is EtherFi Money?
EtherFi Cash is a physical Visa card that allows users to borrow stablecoins against their deposited interest-bearing assets, such as liquid staking tokens. Users can spend their borrowed money at any merchant that accepts Visa, effectively converting their crypto holdings into disposable cash without selling their assets. The card is designed to bridge the gap between DeFi returns and daily expenses.
Why this matters
This proposal represents a significant strategic shift for Ether.fi. By adopting Aave’s infrastructure, the protocol can reduce operational overhead and take advantage of Aave’s deep liquidity, security and developer ecosystem. For Aave, the deal expands its reach into the credit card and real-world asset (RWA) space, potentially bringing new users and liquidity to the protocol. The integration also strengthens the Optimism ecosystem by anchoring a major DeFi application to its network.
For EtherFi Cash users, the transition could mean more stable lending rates, improved reliability and potential access to the internet $GHO as a loanable asset. However, the proposal still needs to be approved by both communities, and timelines for implementation remain uncertain.
Conclusion
Ether.fi’s proposal to integrate Aave V4 on Optimism is a pragmatic move that could improve the reliability and scalability of its crypto credit card while reducing internal development costs. If approved, it would mark a remarkable collaboration between two major DeFi protocols and further blur the lines between decentralized finance and traditional payment systems. The outcome of the board votes will be closely watched by the broader crypto community.
