Compass Bundler lets you build and execute complete DeFi workflows in one atomic transaction, without writing or deploying smart contracts.
Compass Bundler saves up to 60% in gas fees!
Traditionally, deploying DeFi workflows — like lending loops, swaps, and rebalancing strategies — has meant managing multiple transactions, custom Solidity, audits, and security reviews. Compass Bundler changes that. With Bundler, you can:
  • Batch multiple DeFi actions into a single API call
  • Reduce gas costs by collapsing separate transactions
  • Ensure atomic safety — everything succeeds together or reverts
  • Stay non-custodial — users always sign and control their assets
  • Go live in days, not months
Bundler works across Ethereum and is fully integrated with Aave, Morpho, Uniswap, Aerodrome, Pendle, and Sky. It’s designed for funds, wallets, and crypto apps that want to ship faster without compromising on security or flexibility. To get started, see the API reference or explore example workflows in the Quickstart guide. If you are using a smart account setup, continue with the Smart Account Quickstart Guide.
