Gas fees are a critical part of blockchain transactions, especially on Ethereum and Binance Smart Chain (BSC). Understanding how gas fees are calculated and how to optimize transactions can save you money.

In this guide, we’ll cover:
🔹 What gas fees are and how they work
🔹 How to calculate gas fees
🔹 Tips to reduce transaction costs

1. What Are Gas Fees?

Gas fees are transaction costs paid to miners or validators for processing transactions on a blockchain. They:

✅ Prevent spam by making transactions costly.
✅ Reward network participants who validate transactions.
✅ Vary based on network congestion—higher demand = higher fees.

📌 Example: On Ethereum, sending ETH, swapping tokens, or using DeFi protocols all require gas fees.

2. How Are Gas Fees Calculated?

On Ethereum (EIP-1559 Model)

Ethereum gas fees are calculated as:

📌 Total Fee = (Base Fee + Priority Fee) × Gas Limit

✅ Base Fee: A fixed amount burned per transaction, changing based on network congestion.
✅ Priority Fee (Tip): An extra amount you pay to miners to prioritize your transaction.
✅ Gas Limit: The maximum gas a transaction can use.

📌 Example: If the base fee is 30 Gwei, the priority fee is 5 Gwei, and the gas limit is 21,000, then:
Total Fee = (30 + 5) × 21,000 = 735,000 Gwei = 0.000735 ETH

On Binance Smart Chain (BSC)

✅ BSC uses a similar gas model but is much cheaper than Ethereum.
✅ Gas fees are usually below $1 per transaction.

📌 Example: A typical BSC transaction might cost 0.0005 BNB (~$0.10).

3. Tips to Save on Gas Fees

💡 1. Use the Right Time for Transactions
✅ Gas fees fluctuate throughout the day.
✅ Best times: Early mornings (UTC) or weekends when demand is lower.

📌 Tip: Use tools like Etherscan Gas Tracker to check gas prices before transacting.

💡 2. Choose Layer 2 Solutions
✅ Polygon, Arbitrum, and Optimism offer lower gas fees compared to Ethereum mainnet.
✅ These networks batch transactions to reduce costs.

📌 Example: A swap on Uniswap costs ~$20 in gas, but on Arbitrum, it costs ~$0.50.

💡 3. Use Binance Smart Chain (BSC) Instead of Ethereum
✅ Binance Smart Chain (BSC) has lower fees and supports similar DeFi applications.
✅ Many DeFi platforms like PancakeSwap work on BSC.

📌 Example: Swapping tokens on BSC costs $0.10, while Ethereum might cost $10+.

💡 4. Adjust Gas Price Manually
✅ Some wallets allow you to set a custom gas price.
✅ Lowering the gas price can reduce costs, but the transaction may take longer.

📌 Tip: Metamask lets you adjust gas settings before confirming a transaction.

💡 5. Batch Transactions & Use Gas Tokens
✅ Some platforms allow batching multiple transactions to save gas.
✅ Gas tokens (like CHI Gas Token) can be used to pre-purchase gas at lower prices.

📌 Example: Instead of making multiple swaps, batch them into one transaction.
