Saving gas using Compass API - Compass API Docs

Using the Compass transaction Bundler, you can expect to cut your gas-costs in half for complex transactions!

Why Compass Transaction Bundler Saves You Gas

Compass Transaction Bundler reduces gas costs by:

Avoiding repeated base gas fees Instead of paying the base cost for each transaction, it combines multiple actions into one—so you only pay the base fee once.
Reusing loaded information (in the Ethereum Virtual Machine) When the same data is accessed multiple times within a single bundled transaction, it’s much cheaper than accessing it separately in multiple transactions.

Together, these optimizations let you perform the same operations for significantly less gas.Reach out to us—we’d be happy to share more details or run a custom estimate for your use case.

Experiments

We ran tests on Base mainnet using representative DeFi transaction sequences, comparing gas usage with and without Compass Bundler.

Experiment A: 10-Transaction Bundle

Transaction sequence:

View the script used and complete results here.Results: Bundling the 10 transactions into a single atomic transaction saved ~47% in gas (1.89× improvement):

Execution Method	Average Gas Used
Sequential	1,276,383
Bundled	674,067

➡️ View bundled transaction on Basescan — it executed the full sequence using just 672,284 gas.

Experiment B: Larger Bundles

We extended testing to bundles of up to 100 transactions. Gas savings increase with bundle size, though returns diminish:

2× savings at 11 transactions
3× savings at 47 transactions

Bundle Size	Gas Savings
10	47.89%
30	64.05%
50	68.88%
70	68.34%
100	69.45%

Conclusion

Compass Bundler drastically reduces Ethereum gas costs—especially for workflows involving many DeFi operations.

For example, a 2.5× leverage loop on Aave takes 13 transactions to loop and 13 more to unwind. On Ethereum Mainnet, this would typically cost around $6 in gas. With bundling, you’d save about $3. If your protocol routinely rebalances vaults or portfolios, Compass Bundler can yield significant cost reductions. Contact us with your use case to get a tailored estimate.
