10 Best Gas Optimization Tricks For Ethereum
1. Batch Transactions
This collection of algorithmic tasks performed in a single operation lowers gas costs. Batching transactions consists of sending several singular transactions, each with individual gas fees
At once. Instead of sending several singular transactions each incurred with a base fee at gas, they can be sent all at once saving on base gas and easing congestion.
This is very helpful in case of token transfers or contract calls with loops. Smart contracts can implement batch capabilities that let users approve, transfer or interact with many items in one action.
| Feature | Details |
|---|---|
| Combines multiple actions | Reduces the number of transactions sent |
| Saves base gas cost | Only pays base fee once |
| Ideal for repetitive operations | Useful in token transfers, approvals, etc. |
| Improves efficiency | Minimizes network load and execution time |
| Supported in smart contracts | Must be implemented in contract logic |
2. Use Gas Tokens
Gas tokens, including GST2 or CHI, allow users to minimize the cost associated with paying gas fees. Users can mint tokens when gas is cheap, while redeeming them during high-fee periods.
These tokens take advantage of Ethereum’s refund model by minting data while the costs are low and deleting it later to get a refund for gas.
Although Ethereum’s London Hard Fork (EIP-3529) reduced some of the refund value’s beneficiaries, older smart contracts or specific use cases might still hold some advantage.
For developed users and developers, gas tokens offer capitalistic benefits in terms of gas savings if strategically optimized in gas-compatible environments.
| Feature | Details |
|---|---|
| Reduces gas fees at high demand | Redeem tokens during expensive transaction times |
| Mints tokens when gas is cheap | Stores gas efficiency for future use |
| Works with compatible contracts | Some newer contracts may no longer benefit |
| Advanced user strategy | Requires knowledge of gas refund mechanics |
| Limited post-EIP-3529 | Effectiveness reduced after Ethereum updates |
3. Optimize Smart Contracts
One of the most impactful methods of decreasing gas costs is through the efficient writing of smart contract code.
Avoid cost-prohibitive operations such as storage writes, deep loops, and frequent state changes or the use of volatile data types. In contrast, use compact data types, remove non-essential logic strands, and use old values in place of new ones where applicable.
Organizing your contract logic in a manner that minimizes (storage write) operations and leveraging the more preferred ‘view’ or ‘pure’ functions can greatly save gas.
Gas-heavy portions of a contract can be uncovered by tools like Solidity Gas Profiler or Remix IDE. A well-structured smart contract not only saves gas but also enhances performance and user experience.
| Feature | Details |
|---|---|
| Reduces gas-heavy operations | Avoids unnecessary storage writes and loops |
| Uses efficient data types | Smaller types = lower gas |
| Reuses variables | Minimizes redundant logic |
| Cleaner, leaner code | Improves performance and cost |
| Tools available | Use Remix, Hardhat, or gas profilers |
4. Use Layer 2 Solutions
Notable Layer 2 examples like Arbitrum, Optimism, and zkSync offer faster and cheaper services as they run on top of Ethereum. Layer 2 platforms significantly help to ease congestion and lower gas fees by offloading most of the computation and data storage from the Ethereum chain.
Users can move their assets to these protocols and receive the same level of security offered by Ethereum while spending a fraction of the gas.
For dApps and frequent traders, switching or adopting Layer 2 dApps is a no-brainer with regards to conserving costs while maintaining full functionality across the Ethereum ecosystem.
| Feature | Details |
|---|---|
| Lower transaction costs | Significantly cheaper than Ethereum mainnet |
| Faster transaction speed | Near-instant confirmations |
| Compatible with major dApps | Many support Arbitrum, Optimism, etc. |
| Same Ethereum security | Layer 2 inherits Ethereum mainnet security |
| Bridges available | Easy asset transfer between Layer 1 and Layer 2 |
5. Set Gas Price Limits
Defining an upper gas price limit allows users to strategize their transactions so that they don’t overspend when the network is mostly congested.
Rather than going with the wallet’s suggested price, users can override the fee and put in a reasonable figure or a maximum cap. In advanced gas settings, wallets and platforms allow those modifications.
For non-urgent transactions, the method is optimal if the user does not mind waiting for the transaction to go through.
It relinquishes control to the user and ensures you are not competing against everyone else for the same resources. MetaMask users with RPC have tools that assist in lowering spending by setting peg limits that enable cost-saving cap restricting.
| Feature | Details |
|---|---|
| Manual control over gas cost | Users choose how much they’re willing to pay |
| Avoids overpaying | Especially helpful in volatile periods |
| Advanced wallet settings needed | Available in MetaMask, Ledger, etc. |
| Best for non-urgent transactions | May require longer confirmation times |
| Combines well with estimators | Use in tandem for optimal savings |
6. Use Gas Fee Estimators
Automated gas fee estimation tools offer assistance to users to determine the most time-efficient and economical time along with the rate for transacting on Ethereum.
EthGasStation, Gas Now, and even MetaMask offer self-contained wallet estimators that provide real-time updates regarding gas prices, all serve as access points to modern estimators.
These tools enable users to refrain from sending transactions during peak times so that they don’t end up overpaying in excess amounts.
Some estimators go as far as categorizing the rate based on urgency, as in “safe low”, “standard”, and “fast.” To those engaged with intrigued on-chain interactions, such tools prove to be invaluable, especially developers and power users.
| Feature | Details |
|---|---|
| Real-time fee monitoring | See current low, average, and high gas prices |
| Prevents overpaying | Avoid guessing or relying on default suggestions |
| Integrates with wallets | MetaMask, Trust Wallet, etc. use estimators |
| Great for planned transactions | Choose the best time to execute |
| Popular tools | EthGasStation, Gas Now, Blocknative |
7. Avoid Repeated State Changes
Every change to the state of the Ethereum blockchain, for example, updating a variable or writing to storage, utilizes a significant amount of gas. Combining state changes that occur across various transactions and multiple transactions into one is not only inefficient, but expensive.
Smart contracts should be built in a way that state change only occurs when absolutely necessary and consolidates logic when possible.
For instance, instead of updating balances repeatedly in a loop, they can be updated afterwards once all calculations are completed. Minimizing the amount of operations that are performed will reduce the amount of gas that is needed to execute a contract.
| Feature | Details |
|---|---|
| Limits storage writes | SSTORE is one of the most expensive operations |
| Consolidates logic | Perform updates after calculations |
| Reduces gas per function call | Efficient code lowers total execution cost |
| Ideal in loops or iterations | Avoid state updates within loops |
| Part of smart contract optimization | Best done during development phase |
8. Use EIP-1559 Transactions
A new transaction model which contains a base fee that fluctuates according to network demand, as well as a tip that is defined by the user (priority fee) was introduced by EIP-1559. It aids in the stabilization of gas fees and helps in preventing users from being charged exorbitantly.
EIP-1559 compatible wallets allow users to better predict the gas fees that will be incurred and pay the minimum amount required for prompt transaction approval.
Furthermore, the overall transaction cost is lower when there is low network activity since the base fee reduces. Exploiting EIP -1559 features can allow gas spending to be better optimized.
| Feature | Details |
|---|---|
| Predictable base fee | Changes dynamically based on network demand |
| Priority fee (tip) optional | Users control how fast the transaction is mined |
| Reduces overbidding | Less competition for miner attention |
| Supported in major wallets | MetaMask and others support EIP-1559 natively |
| Encourages stable gas pricing | Reduces wild gas fee fluctuations |
9. Choose Off-Peak Times for Transactions
Based on the demand of the network, the gas prices of Ethereum fluctuate. Transactions done during off-peak times such as late evenings or weekends incur much lower fees.
Users can use historical gas price data alongside real-time estimators to plan their transactions around these periods.
This is great for non-urgent tasks like staking, token transfers and contract interactions. The timing of when activities are executed can have a significant impact especially when there is a greater than 2x difference between peak hours and off-peak periods.
| Feature | Details |
|---|---|
| Lower gas costs at night/weekends | Less network activity = cheaper transactions |
| Works for non-urgent actions | Good for staking, minting, or transfers |
| Easy to plan using charts | Use gas history tools to identify quiet periods |
| No special tools needed | Manual timing strategy |
| Maximizes efficiency | Combine with fee estimators for best results |
10. Optimize Token Transfers
Transfers of tokens such as ERC-20 and NFTs tend to consume a lot of gas. Using enhanced standards ERC-777 and newer lightweight protocols can minimize gas expenses.
For multiple transfers, batching them as one single transfer is the most efficient. Allowing multiple transfers and approvals in a single call via custom functions also greatly lowers the need for more than one interaction.
Cutting back on calls while ensuring tokens are gas-efficient aids in securing savings in the long term. After deploying token contracts on the mainnet, ensure that they have been tested and optimized for gas consumption so that they do not incur extra expenses on the network using Tenderly or Remix.
| Feature | Details |
|---|---|
| Use efficient standards | ERC-777 or optimized ERC-20 tokens save gas |
| Batch transfers | Send multiple tokens in a single transaction |
Minimize approve() calls | Reduces unnecessary transactions |
| Smart contract support | Custom batch transfer functions can be added |
| Analyze before deploying | Use tools like Tenderly to test gas impact |
Conclusion
In conclusion The adoption of Ethereum remains low relative to its popularity due to high gas fees. However, they can be substantially reduced by batching transactions, utilizing Layer 2 solutions, optimizing smart contracts, and applying the concepts from EIP-1559.
The proper management of these resources increases the overall efficiency of the network, encouraging developers, traders, and common users to make use of this crypto infrastructure.
