AaveEtherFi made Aave V4 a core part of its EtherFi Cash infrastructure, moving the credit backend to a dedicated V4 instance on Optimism. The backend is now live: cardholders can borrow against PAXG, SPYx, WBTC, ETH, and ETHFI, with more than 100,000 cardholders expected to access the range of collateral as the integration expands.

We built Aave Protocol, an open source and non-custodial liquidity protocol and the Aave app, a web interface for users to interact directly with the protocol.
