Gas fees can eat into your profits fast, especially if you’re trading on busy blockchain networks. But here’s the good news: you can cut those costs by timing transactions right, using layer-2 networks, and simplifying your smart contract usage. Here’s how:

• Time transactions wisely: Trade during off-peak hours like early mornings, weekends, or late evenings to avoid high fees.
• Use tools to track gas prices: Tools like Etherscan’s Gas Tracker and ETH Gas Station help you monitor and plan.
• Try layer-2 networks: Platforms like Polygon or zkSync offer much lower fees compared to Ethereum’s main network.
• Simplify smart contract actions: Combine operations into fewer transactions and design contracts to use less gas.
• Stay updated on upgrades: Blockchain updates like Ethereum’s Dencun upgrade can reduce fees significantly.

Time Your Transactions for Lower Fees

How Network Traffic Affects Gas Prices

Think of network congestion like rush hour traffic - when too many users try to interact with the blockchain at the same time, fees shoot up. Why? Because users start bidding higher gas prices to get their transactions processed faster, creating a competitive cycle that raises costs for everyone.

Gas prices directly reflect how busy the network is. For example, when popular DeFi protocols roll out new features, a hot NFT collection drops, or a major market event unfolds, transaction volumes can spike. This sudden demand often leads to gas fees climbing far beyond normal levels.

Interestingly, weekends tend to see less network activity compared to weekdays, especially during U.S. business hours. This happens because institutional traders and automated DeFi systems are less active during these off-peak times. As a result, there's more room for individual transactions, often at a lower cost. Timing your transactions wisely can make a big difference in how much you pay.

Tools for Monitoring Gas Prices

Several tools are available to help you track gas prices and plan your transactions:

• Etherscan's Gas Tracker: This tool provides real-time gas price data and estimates for slow, standard, and fast transaction speeds. It also shows current network usage, helping you decide the best time to act.
• ETH Gas Station: Offering detailed analytics, this tool includes gas price predictions and historical data. It’s handy for finding recommended gas prices for everything from simple transfers to complex smart contract actions.
• Browser Extensions: Tools like Blocknative's Gas Platform bring real-time gas price updates directly to your browser, making it easy to stay informed.

Many of these tools also include alert systems. You can set a price threshold, and they’ll notify you when gas fees drop below that level. This feature is perfect for automating your transaction timing without needing to constantly check prices.

Best Transaction Times in U.S. Time Zones

Knowing when the network is less busy can save you money. Here are some of the best times to consider:

• Early mornings (2:00 AM to 6:00 AM EST): Gas fees are typically lowest during these hours when both U.S. and European markets are less active.
• Weekends: Saturday mornings and Sunday afternoons are great for cost savings, thanks to reduced activity from corporate and institutional users.
• Late evenings (10:00 PM to midnight EST): This period often sees a dip in fees, as U.S. markets close and international activity hasn’t fully picked up.

On the other hand, it’s best to avoid non-urgent transactions during peak U.S. trading hours (9:00 AM to 4:00 PM EST). During these times, higher network usage tends to drive up gas prices significantly.

Use Layer-2 Solutions

What Are Layer-2 Solutions

Layer-2 solutions are like express lanes for Ethereum. They’re designed to handle traffic more efficiently, making transactions faster and cheaper while still keeping everything secure. These solutions work by processing transactions off the main Ethereum blockchain (Layer 1), bundling them together, and then sending a summary back to the main chain for final settlement.

This approach takes a lot of the load off Ethereum's main network. For example, while Ethereum Layer 1 can handle about 15 to 20 transactions per second, Layer-2 solutions like rollups can process over 1,000 transactions per second. Some networks, like Polygon, can even reach speeds of up to 65,000 transactions per second. As of now, Layer-2 solutions are securing about $36 billion across thousands of decentralized apps.

The cost savings are just as impressive. On Ethereum Layer 1, transaction fees usually range from $0.25 to $0.50 but can skyrocket to $20–$60 when the network is busy. Layer-2 fees, on the other hand, are often under $0.05. Recent upgrades have pushed costs even lower, with some transactions costing as little as $0.0196.

Common Layer-2 Options

There are several types of Layer-2 solutions, each offering unique benefits. The main options include rollups (Optimistic Rollups and ZK-Rollups), state channels, validiums, and nested blockchains.

• Optimistic Rollups: These assume all transactions are valid unless proven otherwise. They’re faster but may have a delay for withdrawals to ensure security.
• ZK-Rollups: These use cryptographic proofs to instantly validate transactions. They’re highly secure and offer immediate finality but require more computational resources.

In March 2024, Ethereum’s Dencun upgrade introduced a feature called "blob space" (EIP-4844), a cost-effective data lane specifically for rollups. This change reduced Layer-2 transaction fees by about 90%. On Starknet, for instance, fees dropped from $6.80 to just $0.04 - a 95% decrease.

Here’s a quick look at current costs on Layer-2 networks compared to Ethereum Layer 1:

Network	Send ETH	Swap Tokens
Ethereum (Layer 1)	$1.10	$5.48
Metis Network	$0.04	$0.18
Loopring	$0.04	$0.59
zkSync Era	$0.07	–
zkSync Lite	$0.09	$0.20

Pick the Right Blockchain for Your Trading

Choosing the right Layer-2 solution depends on factors like how often you trade, the level of security you need, and the type of assets you’re dealing with. For example:

• Low-cost options: Networks like Metis and Loopring are great for traders focused on minimizing fees.
• Fast settlement: ZK-Rollups are ideal if you need instant transaction finality, unlike Optimistic Rollups, which may have withdrawal delays.
• Security-conscious choices: Look for platforms with open-source software, decentralized governance, and transparent fraud-proof systems.

If you need to move assets between Ethereum and a Layer-2 network - or between two Layer-2 networks - you’ll use a process called "bridging." Keep in mind that bridging can add extra fees and take time, so it’s often smarter to stick with one Layer-2 network for all your trading activities to avoid these additional costs.

For frequent traders, networks with ultra-low fees are the way to go. On the other hand, if you’re making fewer but larger trades, the instant finality offered by ZK-Rollups might be more appealing.

Reduce Smart Contract Gas Costs

Design Contracts for Lower Gas Usage

The way you design your smart contract plays a big role in determining gas costs. A well-structured contract can mean the difference between paying a little or a lot for the same transaction. To keep costs down, aim for simple and efficient logic. Avoid unnecessary calculations and steer clear of complex loops whenever possible.

Storage operations are among the most expensive. Writing data to the blockchain costs far more than reading it. To save on fees, developers often rely on memory variables for temporary calculations and reserve blockchain storage for only the most essential data.

Choosing the right data types is another way to make your contract more efficient. While it might seem counterintuitive, using larger, standardized data types can actually save gas because the Ethereum Virtual Machine (EVM) is optimized for them. Additionally, packing multiple smaller values into a single storage slot can lead to even more savings when done correctly.

Function visibility also affects gas costs. External functions, which are called from outside the contract, tend to be more gas-efficient than public functions because they avoid extra parameter copying. For internal calls, internal functions are even more cost-effective.

Finally, grouping operations into fewer transactions, like batching, can further reduce costs.

Batch Multiple Transactions

Batching transactions is a smart way to combine multiple operations into a single transaction, saving on fees overall.

One common approach is using multicall contracts, which allow you to execute several function calls at once. For instance, some platforms let users bundle multiple swaps or token transfers into a single transaction, cutting down on fees.

Composable contracts take this a step further by streamlining processes and avoiding redundant calculations. This approach can significantly lower costs compared to handling each transaction separately.

Timing matters, too. Since batched transactions require more gas, executing them during periods of low network congestion can increase the chances of success while keeping fees manageable.

Track Gas Usage in Your Contracts

Keeping an eye on gas usage is crucial for identifying costly operations and improving your contract’s performance. Gas profiling tools can help pinpoint which parts of your contract consume the most gas.

While Ethereum's built-in gas tracking provides an overall view, specialized tools can break down gas usage by specific functions. This detailed insight makes it easier to find areas where optimizations can save money.

Testing your contract on testnets before deployment is another important step. By estimating gas consumption in advance, you can avoid unexpected fees. Testing also helps you understand how changes in parameters impact gas costs.

Setting gas limits strategically is another way to control expenses. By knowing the typical gas consumption of a function, you can set limits to avoid both excessive fees and failed transactions.

For traders using platforms like Wallet Finder.ai, tracking gas usage across different strategies can uncover the most cost-efficient methods. By analyzing how gas consumption varies with different trading patterns, you can adjust your approach to save on fees while staying profitable.

Track Blockchain Upgrades That Change Fees

Blockchain upgrades can shake up fee structures, impacting costs and trading strategies. Beyond timing your transactions or using layer-2 solutions, keeping an eye on these network changes is another smart way to manage gas fees effectively.

Networks like Ethereum frequently roll out updates that tweak gas fee structures, which can directly affect trading costs and opportunities. Staying informed about these upgrades and understanding their impact is crucial to maintaining a profitable strategy.

Some upgrades lead to lower fees, but the extent of the reduction can vary. Keeping track of these changes and adjusting your trading practices accordingly can make a big difference.

How Recent Ethereum Upgrades Changed Fees

Take Ethereum’s recent Dencun upgrade, for example. It introduced improvements aimed at optimizing data storage for layer-2 networks. One of its key features, EIP-4844, brought in a new transaction type called "blobs", designed to handle data more efficiently.

This upgrade created a dedicated fee market for these data blobs, which helps lower storage costs and makes fees more predictable. Thanks to these changes, strategies that were once too expensive - like frequent arbitrage or small-value transactions - are now more feasible.

Comparing Costs Before and After Upgrades

To take full advantage of fee changes, it’s helpful to compare transaction costs before and after an upgrade. By creating a simple framework to track and analyze these costs, you can spot trends and uncover potential savings as fee structures shift.

Documenting your transaction expenses before and after upgrades can reveal new ways to fine-tune your strategy. Use these insights to adapt your trading approach and maximize efficiency.

Adjust Your Trading for New Fee Structures

Blockchain upgrades often bring fresh opportunities, but they may require you to tweak your strategy. For instance, lower fees can make smaller trades more practical, opening up new arbitrage opportunities and allowing for better risk management through frequent, smaller transactions.

With reduced fees, you might also rebalance your portfolio more often, potentially boosting overall performance. Many traders even shift more activity to layer-2 networks when these upgrades make costs more attractive.

Lower fees also support automated strategies like dollar-cost averaging, systematic arbitrage, and automated rebalancing. Tools like Wallet Finder.ai can help you analyze how other traders adjust after upgrades. By studying wallet performance data, you can identify patterns and refine your own trading approach.

To stay ahead, follow official network announcements and developer updates. Major upgrades are usually announced well in advance, giving you plenty of time to prepare and adjust your strategy for the changes ahead.
