Leverage in Bucket

Bucket supports two ways to build a leveraged long on supported assets:

  • One-click Leverage (currently for SUI/LST and Wrapped BTC)

  • Manual looping (all other supported collaterals)

Both paths keep you inside a single CDP with fixed-rate borrowing. Every action shows an after-action simulation.

One-click Leverage

Step-by-step

  1. Select your deposit asset.

  2. Select the target asset.

  3. Enter the deposit amount.

  4. Set your target leverage (> 1.1×).

  5. Review the preview and costs, then Confirm to execute (one transaction).

Preview & safety

  • Before confirming, you’ll see a simulation of the position at Detail.

  • A simple target-leverage health bar helps you gauge risk.

Routing & slippage

  • Swaps are routed via the Cetus aggregator.

  • You can set slippage tolerance (default 0.5%).

Costs shown in the panel

  • Flash-loan fee

  • Price impact (swap-side estimate)

How it works

The Leverage feature allows users to amplify their exposure to supported assets by using USDB flash minting to automatically create a leveraged position in one click.Leverage Process (Example with SUI):A user starts with 100 USDC and targets approximately 3x SUI exposure.

  1. User deposits 100 USDC

  2. Flash-mints USDB worth 200 USDC

  3. Swaps the user’s 100 USDC + flash-minted USDB for 300 USDC worth of SUI

  4. Uses 300 USDC worth of SUI as collateral → borrows USDB worth 200 USDC

  5. Uses the borrowed USDB to repay the flash-mint

  6. Leveraged position is established

Final Position:

  • Collateral: 300 USDC worth of SUI

  • Debt: USDB worth 200 USDC + borrow fee

  • Net SUI Exposure: ~3x the initial deposit

The same process works for other supported assets (e.g., BTC or SUI LST), with adjustments based on the asset type.

Manual looping (all supported collaterals)

Use manual steps when one-click isn’t available:

  1. Deposit collateral

  2. Borrow USDB

  3. Swap USDB → more collateral

  4. Deposit the new collateral

  5. Repeat until you reach your desired risk level

De-leverage & raising CR

To reduce leverage or raise your CR:

  • Repay with collateral: use the slider to choose how much collateral to sell for USDB, preview the USDB repaid and new CR, then confirm.

  • Repay with USDB: repay from USDB in your wallet (you can swap into USDB first).

  • After repayment, CR rises and your liquidation price moves lower (safer).
