In this post, I am going to talk about gas fee optimization which is important for every single person who uses a blockchain network.
Because of network traffic and the intricacy of the transactions, gas fees can be quite different, but has the right tactics, the cost can be saved tremendously.
I will discuss important methods such as the time of the transaction and the use of Layer 2 solutions.
What are Gas Fees?
Gas fees refer to the costs incurred by users when performing transactions on a blockchain network like sending tokens or interacting with smart contracts.
These fees compensate the miners or validators for validating and processing the corresponding transactions.

For instance, in Ethereum, gas fees are paid in gwei, a smaller unit of Ether. The demand for a network alters gas prices; during periods of congestion, gas fees increase.
Optimizing gas fees involves reducing transaction costs, choosing more affordable networks, and taking advantage of timesaving tactics like gas-efficient Layer 2 Solutions.
How To Do Gas Fee Optimization
For optimization of gas fees, let’s take Polygon (Matic) as an example:

Polygon’s Base Fees Are Lower
Polygon is more accessible to users who gas fee optimize with far lower transaction fees than Ethereum.
Layer 2 Scaling
As a Layer 2 solution, Polygon eases off transactions from Ethereum, lowering the congestion and consequently the fees.
Greater Transactional Speed
Due to lower congestion and an optimized consensus mechanism, polygon boasts of faster transaction processing with lower gas costs.
dApps
Users can interact with DeFi platforms and NFTs on polygon at less than a quarter of what they would pay on Etheream due to many dApps on polygon being tailored for low cost transactions.
Paying in MATIC
Users can incur less in gas fees by paying in MATIC (Polygon’s native token) rather than ETH which is more expensive.
How Gas Fees Work In Different Blockchains
Ethereum (ETH)

- Gas fees are paid in ETH, varying with network congestion and the complexity of the transaction.
- Fees are calculated in “gwei,” which is a fraction of ETH.
- Expensive during peak periods when congestion is high.
Binance Smart Chain (BSC)
- Gas fees are paid in BNB (Binance Coin), sitting far lower than Ethereum’s.
- BSC utilizes a Proof of Staked Authority (PoSA) consensus which allows faster and cheaper transactions.
Solana (SOL)

- Fees to be paid in SOL are extremely low.
- High throughput along with Proof of History (PoH) consensus increase the likelihood of reduced congestion and costs for transactions.
Polygon (MATIC)
- Gas fees paid in MATIC are considerably lower than Ethereum’s, because of its Layer 2 scaling solution.
- The network promises low cost fast transaction finality.
Avalanche (AVAX)

- Gas fees paid in AVAX mark low due to its Avalanche consensus mechanism.
- Avalanche ensures minimum fees alongside rapidly scalable transactions.
Why Gas Fee Optimization Matters
Cost Savings: Most users and businesses appreciate the lowered overall transaction cost, especially for those who need to high volume or frequent transactions.
Terseness: Lowered gas prices leads to cheaper and faster completions of transactions, and thus helps improve overall experience on the various blockchain platforms.
Scalability: Blockchains can handle greater number of unprocessed transactions without the system getting congested or more overwhelmed, thus improving gas usage.
Efficiency: Less spending of gas under unproductive activities makes processes more efficient, and thus makes operations of blockchains better.
Gas Fees: Especially on Proof Of Work Networks, lowered fees of gas can help lessen abnormal energy being consumed or used while carrying out blockchain transactions.
Environmental Effects: For users who wish to avoid being delayed, gas optimization aids them ensure payment of processed transactions is done on lesser fee networks.
Lower Accessibility: Foc gas optimization allows the technology to be accessible for users with less budget and thus helps blockchain technology reach a wider audience.
Techniques For Gas Fee Optimization
Scheduling Trades
Make Trades at Non-Peak Days: Gas costs are dynamic and depend on how many people are using the network. Gas price tools such as GasNow or ETH Gas Station are able to tell you the price of gas so you can do transactions when it is less expensive.
Implement Layer 2 Solutions
- Utilize Layer 2 Networks: Ethereum has other supporting platforms that allow quicker and cheaper transactions and still provide safety. They include Polygon, Optimism and Arbitrum. All of these operate underneath the main Ethereal network.
- Layer 2 Rollups: Other tech that sums up a lot of transactions elsewhere and then records them on Ethereum include zk-Rollups and Optimistic Rollups. Using technology makes it easier to save on gas expenses.
Switch to Cheaper Networks
- Pick Non Ether Blockchains: The Ethereum network is known for high gas fees. Alternative block chains to consider include Binance Smart Chain, Avalanche and Solona which offer speedy services at lower fees.
Avoid Over Paying
- Gas Fee Estimators: With tools such as Blocknative, Gastracker or 1inch, users have the ability of estimating gas fees ahead of time and so they do not overpay.
Efficient Smart Contracts
- Enhanced Smart Contracts: Developers of the smart contracts need to optimize the code within them so that civil execution does not incur high computation costs. This is better for gas expenses if done smartly.
- Batch Transactions: Merging multiple actions into one transaction minimizes gas fees, particularly for operations that involve a lot of work or numerous actions, such as transferring tokens.
Use Gas Tokens
- Gas Token Strategies: On certain networks, it is possible to use gas tokens such as Chi or GST2. These tokens can be used to reduce gas costs and are stored during periods of low prices and redeemed when costs soar.
Select the Right Gas Price
- Select Appropriate Gas Price Tiers: Most wallets and dApps enable you to change the gas price. If there is no urgency for a specific transaction, you can set a lower gas price as long as there’s still a reasonable guarantee that the transaction will execute within the expected time.
Use Aggregators
- Decentralized Exchange (DEX) Aggregators: Services such as 1inch or Matcha aggregate liquidity across various DEXes, enabling them to get better prices for gas fees and save on transaction costs.
Conclusion
To sum it up, optimizing the gas fee in a blockchain network has a considerable impact on its transaction cost along with its efficiency.
Users can save money by strategically scheduling transactions, applying Layer 2 methods, transacting on low-fee blockchains, and refactoring smart contract written code.
In decentralized networks, the overall experience and scalability is improved when users utilize gas fee estimators and aggregators which informs them of gas fee decision opportunities.
