Gas fees are essential to understand for anyone using blockchain networks like Ethereum or Aptos. Whether you're transferring cryptocurrency, using decentralized applications (dApps), or minting NFTs, knowing how gas fees work can save both time and money.
This guide explains what gas fees are, how to monitor them, and highlights the differences between Ethereum and Aptos networks. You'll also learn practical strategies to optimize your transaction costs.
What Are Gas Fees?
Gas fees represent the cost required to perform transactions or execute operations on a blockchain. These fees compensate network validators or miners for the computational resources used to process and verify transactions. You can think of gas fees as a usage charge for blockchain services—similar to paying a toll on a highway.
On Ethereum, gas fees are paid using ETH and fluctuate based on transaction complexity and overall network demand. Aptos, a newer Layer 1 blockchain, also implements gas fees but utilizes a distinct architectural approach aimed at scalability and affordability.
How to Track Gas Fees
Monitoring gas fees helps users identify optimal times to execute transactions, ultimately reducing costs. Here’s how you can track fees on both Ethereum and Aptos:
- For Ethereum: Platforms like Etherscan and GasNow provide real-time gas price data, displayed in Gwei—a subunit of ETH. These tools help estimate costs for various actions, from simple transfers to smart contract interactions.
- For Aptos: The Aptos Explorer offers live insights into network fees. Although Aptos is designed for low-cost transactions, monitoring remains useful during high-demand periods.
- Cross-Chain Tools: Applications such as DeFi Saver support multi-network gas tracking, including Ethereum and Aptos.
Using these tools can lead to significant savings. For instance, executing a transaction when gas prices drop from 100 Gwei to 20 Gwei can reduce costs substantially.

Understanding Ethereum Gas Fees
Ethereum gas fees are a frequent topic of discussion due to the network’s popularity for dApps, DeFi, and NFTs. Here’s a breakdown of how they work:
- Gas Limit and Gas Price: Each transaction specifies a gas limit (maximum computational units) and gas price (cost per unit). The total fee equals gas limit multiplied by gas price.
- Base Fee and Priority Fee: Post-London upgrade, Ethereum introduced a base fee (destroyed by the network) and a priority fee (paid to miners for faster processing). During congestion, the base fee increases significantly.
- Key Influencers: Network activity—such as NFT launches or DeFi events—along with transaction complexity and market conditions heavily influence ETH gas fees.
While Ethereum fees can be volatile, tools like Etherscan’s Gas Tracker provide historical and current data to help users plan transactions.
Aptos Gas Fees: A Scalable Alternative
Aptos is a Layer 1 blockchain designed for high throughput and low-cost transactions. Launched in 2022, it uses a parallel execution engine to achieve faster processing speeds. Here’s what you should know:
- Fee Structure: Aptos transaction fees include a base gas cost plus additional charges tied to storage and execution requirements.
- Cost Efficiency: Thanks to high throughput capabilities (theoretically up to 160,000 TPS in test environments), Aptos fees are often lower than $0.01 per transaction.
- Tracking Fees: The Aptos Explorer allows users to monitor real-time gas prices, helping capitalize on the network’s low-cost environment.
Aptos offers an appealing option for developers and users looking for affordable and rapid transactions.
Ethereum vs. Aptos: Gas Fee Comparison
The table below highlights key differences between the two networks:
| Feature | Ethereum | Aptos |
|---|---|---|
| Average Gas Fee | $2 – $50 (highly variable) | < $0.01 (generally stable) |
| Transaction Speed | ~15 TPS (without Layer 2) | Up to 160,000 TPS (testnet) |
| Primary Use Cases | dApps, NFTs, DeFi | Scalable apps, low-cost DeFi |
| Tracking Tools | Etherscan, GasNow | Aptos Explorer |
Ethereum remains the leader in ecosystem maturity, but its fees can be high. Aptos offers a low-fee environment suitable for users and developers prioritizing cost and scalability.
Tips to Reduce Gas Fees
Apply these strategies to minimize transaction costs on both networks:
- Schedule Transactions: On Ethereum, execute transactions during off-peak hours (e.g., late night UTC) when network demand is lower.
- Use Layer-2 Networks: For Ethereum, consider using scaling solutions like Arbitrum or Optimism to benefit from reduced fees.
- Batch Operations: Combine multiple transactions into one to save on gas.
- Leverage Aptos: For suitable use cases, using Aptos can ensure consistently low fees.
- Adjust Gas Settings: When using Ethereum wallets like MetaMask, manually set gas limits to avoid overpayment.

Frequently Asked Questions
What are gas fees?
Gas fees are payments users make to process transactions or execute smart contracts on a blockchain. They reward network participants for validating operations and maintaining security.
Why are Ethereum gas fees so high?
Ethereum fees rise during periods of high network demand—such as popular NFT mints or DeFi launches—due to limited block space and competitive transaction processing.
How can I avoid high gas fees on Ethereum?
You can avoid high fees by transacting during low-activity periods, using Layer-2 solutions, batching transactions, or exploring alternative networks like Aptos.
Are Aptos gas fees always low?
While Aptos is designed for low fees, costs can still increase during extreme network usage. However, due to high throughput, fees typically remain very affordable.
Which is better: Ethereum or Aptos?
The choice depends on your needs. Ethereum offers a well-established ecosystem, while Aptos offers high speed and low cost. Your decision should be based on project requirements and budget.
Can I track gas fees for both networks in one place?
Yes, some multi-chain platforms like DeFi Saver allow you to monitor gas fees across several blockchains, including Ethereum and Aptos.
Conclusion: Mastering Gas Fees
Understanding gas fees is crucial for efficient and cost-effective blockchain usage. Whether you are dealing with Ethereum’s variable fees or Aptos’ low-cost environment, tracking tools and strategic planning can lead to major savings.
By using network-specific explorers and applying optimization techniques, you can take control of your transaction costs and enhance your overall blockchain experience.
