What Are Gas Fees? Why They Rise and How to Save
Bottom line: the cost of a transaction
A gas fee is the cost of running a transaction or contract on a blockchain, especially Ethereum. It's like fuel for using the network.
Key takeaways
Fees rise with demand (congestion). Measured in "gwei". You can save by using Layer 2, avoiding busy times, and not sending many tiny transactions.
Why fees rise
Each block holds a limited amount. When more people want in, a fee auction pushes gas up — which is why fees spike during popular NFT mints.
How to save
- Use Layer 2 (Arbitrum, Optimism) — much cheaper
- Avoid congestion — pick quieter times
- Batch — don't send many small transactions
Test small first
Wallets show a fee estimate before you confirm — always check it.
