Introduction

🎓 Key Takeaways

Congratulations! You've mastered gas fees. Let's review the essential concepts you've learned.

⚖️

Base Fee

Dynamic fee that adjusts with network congestion. Burned to make ETH deflationary.

⚡

Priority Fee

Optional tip to validators for faster inclusion. Higher tips = faster confirmation.

🔢

Gas Limit

Maximum gas authorized. Unused gas is refunded. Protects against runaway execution.

📦

Batching

Combine multiple operations into one transaction. Saves 50-70% on gas costs.

⏰

Timing

Weekends and late nights have 40-60% lower fees. Avoid mid-week peak hours.

🌉

Layer 2

Use L2 solutions for 10-100x cheaper transactions with Ethereum security.

📊

Monitor Real-Time Fees

Use Etherscan Gas Tracker or Blocknative to track live gas prices before transacting.

🌉

Explore Layer 2

Try Arbitrum, Optimism, or zkSync for drastically cheaper transactions.

💻

Optimize Your Code

For developers: learn gas-efficient Solidity patterns to save users money.

📦

Batch Your Transactions

Use multicall contracts or Gnosis Safe to combine operations and save 50-70%.
