Frequently Asked Questions
What is gas in Ethereum?
Gas is the unit that measures the computational effort required to execute operations on the Ethereum network. Every transaction requires gas, and users pay for gas in ETH.
What is Gwei?
Gwei is a denomination of ETH (1 ETH = 1,000,000,000 Gwei). Gas prices are typically quoted in Gwei because the amounts are more readable than tiny fractions of ETH.
Why do gas prices fluctuate?
Gas prices are determined by supply and demand on the network. When many users want to make transactions, gas prices increase. During low activity periods, prices decrease.
What is gas limit?
Gas limit is the maximum amount of gas you are willing to spend on a transaction. Simple ETH transfers use 21,000 gas, while complex smart contract interactions may use much more.
How can I save on gas fees?
You can save on gas by transacting during low-activity periods (weekends, late nights), using Layer 2 solutions, or waiting for network congestion to decrease.
