Before you go any further, just know that https://app.gearbox.fi/accounts/strategies/list has the list of strategies that ape for you in one click! That's right: you configure your collateral asset(s), debt asset, leverage factor... and it does all of it for you in one click. So if you just wanna do some vanilla farming - this could be the recipe for you. But keep reading to learn about other hot stuff possible with composable leverage.
While a developer can run all of the complex interactions onchain, executing these by going protocol to protocol is a tough task. Gearbox devs have worked this out, to have the dApp help non-technical users ape into strategies with one click thanks to "One-Click Strategies".
