What is Gas Fee?
Gas fees are payments made to compensate Ethereum network validators for the computational energy required to process and validate transactions on the blockchain.
What Are Gas Fees?
Gas fees are transaction costs on the Ethereum network, measured in "gwei" (a fraction of ETH). They compensate validators for the computational resources needed to execute transactions and smart contracts.
How Gas Fees Work
Each operation on Ethereum requires a certain amount of gas. The total fee = Gas Units × Gas Price (in gwei). After EIP-1559, fees have two components: a base fee (burned) and a priority tip (to validators).
Why Are Gas Fees High?
Ethereum is a shared resource. During high demand (NFT drops, DeFi surges), users bid up gas prices to have their transactions processed faster. This can push fees to $50-$200+ per transaction.
How to Reduce Gas Fees
- Use Layer 2 networks (Arbitrum, Optimism, Base)
- Transact during off-peak hours (weekends, late nights UTC)
- Use gas trackers to find optimal times
- Batch transactions where possible
