# Leverage Loops

> Execute complex leveraged yield strategies

These routes automate complex leverage strategies, where an asset is used as collateral to borrow another asset, which is then re-deposited to amplify yield, all within a single transaction.

<Info>
  **Note on Route Mechanics:** The steps listed below are illustrative of a possible path. Enso's API dynamically calculates the most efficient route at the moment of execution, so the exact swaps and bridges may vary based on real-time market conditions.

## WBETH to USDT Vault Leverage Loop

Execute a leverage loop on Katana by supplying `WBETH` as collateral to borrow and deposit stablecoins into a Yearn `USDT` vault.

  tokenIn: [WBETH],
  tokenOut: [yvvbUSDT],
  routingStrategy: "delegate",

**Route Mechanics:**

* Redeem `WETH` for native `ETH`.
* Swap native `ETH` to `cbETH`.
