Understanding Gas Fees and Optimization — Quick Tutorial

If you’ve ever made a blockchain transaction — buying an NFT, swapping tokens, or deploying a smart contract — you’ve probably noticed “gas fees.”

These small but vital costs determine how quickly and efficiently your transaction is processed. Understanding gas fees and how to optimize them is essential for anyone working with Ethereum, Polygon, or BNB Smart Chain networks.

At AI Computer Classes – Indore, we break down blockchain concepts into practical, real-world lessons so learners can master technical skills without getting lost in jargon.

Let’s explore what gas fees are, how they work, and how you can minimize them efficiently.

⚙️ What Are Gas Fees?

In blockchain networks, gas refers to the computational effort required to perform operations — from sending tokens to executing smart contracts.

Think of it as paying for electricity when you use your computer — every transaction consumes computational energy, and miners or validators charge a fee for it.

ConceptDescriptionGas UnitThe measure of work needed to execute operationsGas Price (Gwei)The amount paid per unit of gasTotal FeeGas Unit × Gas PricePaid InNative token (like ETH, MATIC, or BNB)

💬 Example:

If a transaction requires 21,000 gas and the gas price is 30 Gwei, your total fee = 21,000 × 30 Gwei = 0.00063 ETH.

🧠 Why Gas Fees Fluctuate

Gas fees are not fixed — they vary based on:

• ⏰ Network congestion (more users = higher fees)
• 📈 Complexity of smart contracts (more code = more gas)
• 💰 Priority levels (faster confirmation = higher gas price)

On busy days, Ethereum transactions can cost $20 or more, while during quiet times, it might drop below $1.

💡 Tip: Always check the network’s average gas price before sending transactions using tools like Etherscan Gas Tracker.

🚀 How to Optimize Gas Fees

Here’s how you can reduce gas costs effectively:

1. Time Your Transactions

Gas prices are lowest during off-peak hours (typically late night or early morning IST).

🕐 Try sending transactions between 2 AM and 6 AM IST for lower costs.

2. Use Layer 2 Solutions

Platforms like Polygon, Arbitrum, and Optimism process transactions faster and cheaper than the Ethereum mainnet.

⚡ Many dApps now support these networks natively.

3. Set Custom Gas Fees

Most wallets (like MetaMask) allow you to manually adjust gas fees.

• Choose Low for non-urgent transfers
• Choose High for instant confirmation
• Experiment with the “Advanced” settings to set custom Gwei values

4. Batch Transactions

Combine multiple actions (like token transfers or swaps) into one contract call to reduce overhead fees.

5. Use Gas Tokens (where supported)

Some advanced users utilize tokens like Chi or GST2 (when available) to pre-purchase gas at lower prices — though this is now less common with Ethereum’s EIP-1559 model.

🔍 EIP-1559 and Gas Optimization

Ethereum’s EIP-1559 upgrade changed how gas works by introducing a base fee and a priority tip.

This system makes fees more predictable but also introduces strategic optimization:

• Monitor the base fee before confirming a transaction
• Adjust your Max Priority Fee for desired speed
• Avoid overpaying by checking live rates on Etherscan

💬 ChatGPT Tip:

Ask ChatGPT to explain current gas fee trends or simulate gas fee savings:

“Explain how EIP-1559 affects Ethereum gas optimization using simple examples.”

💡 Hands-On Exercise: Track and Analyze Gas Fees

Try this mini project at AI Computer Classes – Indore:

1. Open MetaMask and switch to Ethereum Mainnet.
2. Check gas fee under “Advanced Settings.”
3. Record current gas prices (Low, Medium, High).
4. Create a small Excel or Power BI dashboard comparing time-based variations.
5. Use formulas to calculate the average fee per transaction.

This helps you visualize cost patterns and apply data analysis techniques — integrating blockchain knowledge with data tools.

🧮 Bonus: Integrate Gas Fee Data with Power BI

Want to see blockchain data in a professional dashboard?

Here’s how:

1. Use an API (like Etherscan’s Gas Tracker API).
2. Connect it to Power BI via the Web connector.
3. Build a chart showing gas prices by hour/day.
4. Apply filters and DAX formulas to calculate trends.

💬 Result: A real-time blockchain cost-monitoring dashboard!

🧩 Common Mistakes to Avoid

• ❌ Sending high-value transactions during peak times
• ❌ Ignoring fee previews in wallets
• ❌ Forgetting to check Layer 2 support
• ❌ Using outdated networks or dApps

Always double-check network details — especially when bridging assets or interacting with smart contracts.
