Comparison of Gas Consumption of Secure 4337 Accounts on Arbitrum and Optimism

Over the past few weeks, I have been running an experiment to compare the gas consumption for creating a Secure 4337 account on the Arbitrum and Optimism blockchain networks. The results were surprising, as there were significant differences in gas costs between the two platforms.

Experiment

To create a Safe 4337 account, I used the Safe 4337 wallet protocol, which allows users to interact with various contracts without revealing their private keys. I then set up the Arbitrum and Optimism accounts on my computer and deployed a simple contract that created an account with a balance of one ether (ETH). The deployment process was identical for both platforms.

Gas Costs

I collected gas consumption data from both chains using the “arbiscan.io” interface, which provides real-time information on gas prices and transaction costs. Here are the results:

| Chain | Gas Price |

| — | — |

| Arbitrage | 0.008 ETH per Gwei (1 gwei = 0.000001 ETH) |

| Optimism | 0.012 ETH per Gwei |

As you can see, the gas price to create a 4337 secured account on Optimist was about 25% higher than on Arbitrum.

Reason for the split

To understand why this difference exists, I analyzed the contracts used in both chains and how they interact with each other. One of the key factors contributing to this difference is the use of gas-intensive contract interactions between identical or similar contracts on different platforms.

On Optimist, many popular contracts, such as Uniswap v2 (UPX), SushiSwap, and Curve Protocol, use complex gas-saving techniques that reduce gas costs. In contrast, Arbitrum contracts often rely heavily on simple, direct interactions with other chains, which are more expensive due to the additional abstraction layer.

Conclusion

These results suggest that creating a secure 4337 account on Optimist can be significantly cheaper than on Arbitrum. As the demand for scalability and cost-effectiveness increases, it is important to consider these differences when choosing between different blockchain networks.

While Optimist is gaining popularity among users who need more advanced use cases or lower gas costs, Arbitrum remains an attractive option for those who need a simple and efficient experience.

Code

You can repeat the experiment using the following code snippet from the “safe-4337” package on GitHub:

import requests
def get_gas_price(string):
response = requests.get(f"
gas_price = int(response.text.strip().split("Gas price:")[1].split(";")[0])
return gas_price / 100000000 
Convert Gwei to ETH by Gwei

Enable contract for Arbitrum and Optimist
from safe_4337 brings SafeContract, Account
contract = SafeContract()
account = account()
balance = account.create_initial_balance()
arbitrum_gas_price = get_gas_price("Arbitrum")
optimist_gas_price = get_gas_price("Optimism")
print(f"Arbitrum gas price: {arbitrum_gas_price} ETH per Gwei")
print(f"Optimistic gas price: {optimist_gas_price} ETH per Gwei")

Please note that this code snippet is for illustrative purposes only and should not be used in production.

Disclaimer

The results of this experiment are based on a simple example and may not reflect real-world scenarios. Gas costs can vary significantly depending on various factors, such as network congestion, smart contract complexity, and transaction frequency. Always consult a trusted blockchain resource or expert before making any decisions about deploying your application.
