How to Reduce Ethereum Fees?

Basics

Ethereum transaction fees are influenced by blockchain congestion and the complexity of the operations. Ethereum has many users but low performance, resulting in high and consistent fees. The payment is calculated based on the gas limit for a specific transaction and the cost of gas at a given time. There are several main ways to reduce fees in Ethereum. These include using the network during periods of low activity, combining transactions, and exploring other options. A popular method to reduce transaction fees is through Layer 2 solutions and sidechains.

What Is Ethereum Gas?

In Ethereum, "gas" refers to the computational resources needed to execute operations such as token transfers, asset issuance, or smart contract interactions. These operations require virtual machine resources, quantified in gas. Gas prices are denominated in Gwei, a subunit of Ethereum equal to 0.00000001 ETH. The computational resources required for a transaction vary based on Ethereum blockchain congestion and operation complexity.

The gas limit represents the computational resources needed for a transaction, akin to the amount of fuel required for a journey. Transaction costs are calculated by multiplying the gas limit by the gas price in Gwei. For instance, a transaction requiring 21,000 gas units at 14 Gwei per unit would cost 0.000294 ETH. As of June 2024, transferring USDT on Ethereum costs approximately $0.59 in gas, while more complex operations like asset exchanges on Uniswap cost around $11.33​ in Gwei.

The August 2021 London hard fork introduced changes to the fee structure, including an ETH burn mechanism and dynamic block sizes based on network load. Detailed fee calculation methods are available on the Ethereum Foundation's website.

Despite Ethereum's widespread use and hosting of popular applications, its performance has not significantly improved since its 2015 launch, lagging behind newer projects like Polkadot, Solana, and Algorand. Consequently, Ethereum's transaction fees remain high, especially for smart contract operations.

Layer 2 Solutions for Reducing Ethereum Fees

Despite persistently high fees on the Ethereum network, there are currently ways to reduce transaction costs through numerous Layer 2 protocols designed to address this issue.

Layer 2 solutions, based on rollup technology, operate by processing transactions off the main Ethereum network. These transactions are batched together and then confirmed on the Ethereum blockchain. Prominent Layer 2 projects include Arbitrum, Optimism, Loopring, ZKSync, Boba Network, and Aztec Network.

Here are the transaction and swap fees for Ethereum and some Layer 2 projects as of June 2024:

NetworkSending ETHSwap
Ethereum$1.48$11.33
Loopring$0.07$0.42
ZKSync$0.05$0.38
Arbitrum One$0.08$0.23
Boba Network$0.19$0.35
Optimism$0.21$0.31

Sidechains in Ethereum, such as Matic (Polygon PoS), Gnosis Chain, and Loom Network, use independent security systems and consensus algorithms. These sidechains, while separate from Ethereum, also aim to increase transaction speed and reduce costs for assets on the parent network.

Strategies to Reduce Ethereum Fees

  1. To minimize Ethereum transaction fees, consider using the network during periods of low congestion. According to Ethereumprice, the lowest fees typically occur on Monday mornings.
  2. In wallets like MyEtherWallet and Metamask, you can manually adjust the fee for your transaction. Ensure you do not set it below the minimum recommended amount to avoid failed transactions.
  3. Simulate transactions beforehand to estimate their actual cost using tools such as Tenderly or DeFI Saver, which can emulate your transactions.
  4. Explore alternative blockchains with lower fees and faster transaction speeds. EVM-compatible networks like BNB Chain, Polygon (Matic), or Fantom offer similar ecosystems to Ethereum. Additionally, independent projects such as Solana, Cardano, or Near provide viable options.
  5. Utilize applications like Balancer that aggregate transactions from multiple users, reducing the fee for each participant. Some DeFi projects also offer discounts and bonuses for transactions involving assets within the Ethereum ecosystem.

Conclusion

While the Ethereum network faces challenges with performance and fees, strategies such as using periods of low activity, fee adjustments, and transaction simulations can help manage costs. Layer 2 solutions and sidechains, including projects like Arbitrum and Polygon, offer significant fee reductions by processing transactions off the main network. Exploring alternative blockchains and leveraging applications that aggregate transactions can further optimize transaction expenses.
