Bundlers

Bundler3: combine supply, borrow, swap, and other Bend actions into a single atomic transaction; gas savings.

Bundlers let you run multiple Bend actions in one transaction. You avoid multiple confirmations and pay gas once.

Bundler implementations

Bundler3 is Morpho’s main bundler and is built into the Morpho UI so you can run complex flows with one action.

Bundler3 capabilities

With Bundler3 you can:

1. Combine workflows — Supply, borrow, swap, and more in a single transaction
2. Save gas — One transaction instead of many
3. Avoid partial failures — If any step would fail, the whole transaction reverts
4. Run advanced flows — Actions that normally need several steps in one go

Examples

• One-click leverage: Convert $BERA to $WETH, supply as collateral, and borrow $HONEY in one transaction
• Refinancing: Borrow from one market, repay another, and adjust collateral in one transaction
• Rebalancing: Withdraw, swap, and redeposit across markets without waiting for separate confirmations
