This strategy earns blended cbBTC, ETH, and COMP yields by taking advantage of differences in Aave and Compound.

By depositing cbBTC into Aave, this strategy earns 1x the Aave cbBTC lending interest. This also allows the strategy to borrow WETH against the cbBTC collateral with a 20% buffer.&#x20;

Borrowed WETH from Aave is swapped for cbETH earning the interest differentials between cbETH liquid staking yields and Aave WETH borrow interest.

The cbETH is then used to create a 7x leveraged cbETH:ETH position (5% liquidation buffer) which earns an additional 6x interest differential between cbETH liquid staking yields and Compound WETH borrow interest. The total WETH borrowed on Compound also earns additional COMP borrow rewards.

\+ cbBTC supply interest (Aave)

\+ cbETH liquid staking yields

\- ETH borrow interest

\+ COMP rewards on ETH borrow (Compound)
