This pool is Rage Trade's Delta Neutral Risk-Off vault that lends USDC on Aave V3. It also lends USDC to the Risk-On vault, which uses the USDC to short the ETH and BTC exposure in GLP, to earn a fraction of GLP rewards. The Risk-Off vault earns interest on the entire USDC position in Aave as collateral for the Risk-On vault's short position.
