In Aave v2, users can deposit CRV tokens into the protocol's liquidity pools, where they earn interest over time. These deposits can also be used as collateral to borrow other cryptocurrencies, with interest rates determined algorithmically based on supply and demand. The Aave v2 platform introduces features like flash loans, rate switching, and collateral swapping, providing flexibility for users managing CRV and other assets. CRV holders in Aave v2 also benefit from enhanced yield farming opportunities, combining Curve's stablecoin incentives with Aave's lending rewards.
