The good news is that Ethereum is currently focusing on construction and shifting its focus to expansion solutions, so expensive gas fees will no longer be a hindrance. The looming question is that Ethereum is still in a transition period.

6 Ways to Save on Ethereum Gas Fees

1. Optimize trading timing

With different on-chain activities and changes in the market around the world, the price of Ethereum gas may fluctuate greatly within a day. Therefore, in some cases, the gas price is usually lower. It's also a good start to lower gas costs if you catch the moment and make the transaction. So what is the best time to trade?

Generally speaking, gas prices are higher on weekdays and lower on weekends, so weekends are a good time to trade.

“The busiest time of day is also the time with the highest fees. Generally 8am to 1pm ET. Lowest time is midnight to 4am ET.”

So you can also choose to trade on weekdays, and gas costs may be lower than otherwise.

2. Use the Ethereum expansion plan

Ethereum’s ecosystem of scaling solutions is still in its early stages, but the projects already running are impressive and getting better day by day. You can use these schemes to enjoy instant low price transactions on Ethereum.

In the process, you can use Layer 2 solutions, such as projects based on Optimistic rollups and mutual ZK-rollups, which provide ultra-efficient infrastructure while inheriting all the security guarantees of Ethereum.

In addition, there are sidechains with scalable technology to choose from. Such as Polygon's PoS chain or xDAI, they can effectively separate high-efficiency blockchains, but are consistent with Ethereum and meet the needs of Ethereum.
As you go further, you may only need to occasionally interact with the Ethereum main chain, and handle most of your crypto activity at an affordable price in Layer 2 and cross-chain environments. So it will benefit us to become familiar with these solutions as early as possible.

3. Using Gas Tokens

In simple terms, you can mint gas tokens when gas fees are low, and then redeem them when gas prices rise, so you can get a refund in ETH and use that money to pay for your gas fees.

Gas tokens work because Ethereum's storage refund system can refund Ethereum users who delete storage variables, which reflects the flexibility of Ethereum.GasToken.io。

Gas tokens actually lead to gas pricing inefficiencies, so they may be phased out in the next few years. But it can also reduce your gas costs at the same time, so it is still beneficial to users at present. A current popular gas token project is

The project has two different tokens, GST1 and GST2, which work in a similar way. To spend one of these tokens, you simply go to the “Contracts” page on EtherScan and use the “Mint (Mint) and Unlock (Free)” functionality. Every time you release tokens, you get a refund in Ethereum, which is used to pay for your gas.

4. Use Dapps that minimize gas costs

Some decentralized applications on Ethereum explicitly provide gas-minimized products.Balancer V2Examples include Yearn’s V2 Vaults and KeeperDAO, which together automate and batch user transactions. Therefore, everyone does not have to pay the gas fee manually each time, but each person can pay in one lump sum, which greatly reduces the gas fee for everyone.

trading agreement. The V2 system makes the Balancer thread a large treasury rather than a pool of many combinations, which makes the gas price of transactions through Balancer much cheaper.

Using the app with the best gas price in the contract is one of the easiest ways to save money on gas, you just have to compare which one saves you the most!

5. Formulate trading strategies through DeFi Saver

If you can test and simulate transactions without executing them, how much gas do you have to pay before paying?

Here's how the process works. You can use the Recipe Creator to sequence any type of Ethereum activity you want, then run emulation mode to test those activities without paying any gas fees.

This system is not a direct way to save gas costs, but it is a way of adjusting transactions that helps us reduce gas costs.

The Ethereum project knows that users are currently plagued by high gas prices, so some projects provide users with gas discounts to reduce user expenses.BalancerandFurucombo。

andFurucomboEarlier this year, Balancer launched a plan that will refund the gas fees of some trading pairs to some users who trade through Balancer through the related governance token BAL. This means that if you are going to be doing DeFi transactions, consider doing so through Balancer, as you will earn a decent amount of BAL just for transactions made through the protocol.

These projects are new, but so far have been successful for the respective protocols. If more agreements adopt similar procedures in the future, it will be a natural result.
