Ether.fi Proposes Aave V4 Integration to Power Its Crypto Credit Card

Ether.fi, the Ethereum restaking protocol, has put forward a governance proposal to replace the backend infrastructure of its crypto credit card, EtherFi Cash, with Aave V4 on the Optimism network. The move aims to offload the operational burden of running a proprietary lending engine and leverage Aave’s battle-tested liquidity infrastructure.

Proposal Details

The proposal, submitted to both the Ether.fi and Aave DAOs, suggests replacing the current Debt Manager system—which handles credit and lending for the EtherFi Cash card—with Aave’s V4 lending protocol. Ether.fi has cited the increasing complexity and resource demands of operating its own lending engine as the primary reason for the change. In exchange for providing the V4 deployment source code and an operating license, Aave would receive 20% of the Reserve Factor Income generated from the market.

Aave’s stablecoin, GHO, will be added as the primary borrowable asset in this new market. Future integrations could allow GHO to be used for direct payments and deposits on the EtherFi Cash card, though this would require separate approval from the Aave DAO.

What Is EtherFi Cash?

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 funds at any merchant that accepts Visa, effectively turning their crypto holdings into spendable cash without selling their assets. The card is designed to bridge the gap between DeFi yields and everyday spending.

Why This Matters

This proposal represents a significant strategic shift for Ether.fi. By adopting Aave’s infrastructure, the protocol can reduce its operational overhead and benefit from 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 its protocol. The integration also strengthens the Optimism ecosystem by anchoring a major DeFi application to its network.

For users of EtherFi Cash, the transition could mean more stable lending rates, improved reliability, and potential access to GHO as a borrowable asset. However, the proposal is still subject to governance votes from both communities, and timelines for implementation remain uncertain.

Conclusion

The Ether.fi proposal to integrate Aave V4 on Optimism is a pragmatic move that could enhance the reliability and scalability of its crypto credit card while reducing internal development costs. If approved, it would mark a notable collaboration between two major DeFi protocols and further blur the lines between decentralized finance and traditional payment systems. The outcome of the governance votes will be closely watched by the broader crypto community.
