What is gas in Ethereum?

Gas is the unit measuring computational effort on Ethereum. Every operation costs gas. Users pay gas fees in ETH to compensate validators for processing transactions.

Gwei is a denomination of ETH. 1 ETH = 1 billion Gwei. Gas prices are quoted in Gwei. A price of 30 Gwei means each unit of gas costs 0.00000003 ETH.

Why do gas fees fluctuate?

Gas fees follow supply and demand. When the network is busy (NFT drops, DeFi activity), fees spike. During low activity, fees drop. EIP-1559 added a base fee that adjusts automatically.

How can I reduce gas fees?

Transact during low-activity periods (weekends, late night UTC), use Layer 2 networks (Arbitrum, Optimism, Base), batch transactions, or use gas tokens for complex operations.

What is the gas limit?

Gas limit is the maximum gas you're willing to spend. Simple ETH transfers use 21,000. Complex smart contract interactions can use 200,000+. Unused gas is refunded.
