Woofun AI reports that Ether.fi has submitted a governance proposal to replace the backend infrastructure of its EtherFi Cash credit card with Aave V4 deployed on the Optimism network. This strategic pivot seeks to eliminate the resource-intensive burden of maintaining a proprietary lending engine by leveraging Aave's established liquidity infrastructure. The initiative targets a fundamental restructuring of how the protocol manages credit for its payment product.

The technical core of this shift involves dismantling the current Debt Manager system in favor of Aave's V4 lending protocol, a change requiring dual approval from both the Ether.fi DAO and the Aave DAO. Under the proposed terms, Aave would receive 20% of the Reserve Factor Income generated by the market in exchange for providing the V4 deployment source code and an operating license. This revenue-sharing model aligns incentives while transferring the technical maintenance of the lending logic to the Aave ecosystem.

Asset integration plans designate Aave's native stablecoin, GHO, as the primary borrowable asset within the new market structure. While the current proposal focuses on the lending backend, future iterations could enable GHO for direct payments and deposits on the EtherFi Cash card, contingent upon a separate approval vote by the Aave DAO. This layered approach ensures that stablecoin utility expands only after specific governance mandates are met.

Per Woofun AI, the EtherFi Cash product functions as a physical Visa card allowing users to borrow stablecoins against interest-bearing assets like liquid staking tokens. By utilizing borrowed funds at any Visa-accepting merchant, cardholders convert their crypto holdings into spendable cash without selling their assets. This mechanism effectively bridges the gap between earning DeFi yields and executing everyday transactions.

Adopting Aave's infrastructure offers Ether.fi a reduction in operational overhead while granting access to superior liquidity depth and security guarantees. For the Optimism ecosystem, anchoring such a significant DeFi application strengthens its position in the real-world asset sector and potentially lowers lending rates through increased efficiency. The proposal's success hinges on governance votes from both communities, with implementation timelines remaining undefined pending these decisions.

This collaboration signals a broader trend where major DeFi protocols increasingly interoperate with traditional payment systems to enhance user utility. If ratified, the integration would represent a pragmatic step toward blurring the boundaries between decentralized finance and conventional banking infrastructure. The broader crypto community will closely monitor the outcome of these governance votes as a precedent for future cross-protocol partnerships.
