Gas fees are transaction costs on blockchain networks. On Ethereum, every transaction — from a simple transfer to a complex smart contract interaction — requires gas. Understanding how gas works helps you time and configure transactions to pay significantly less.
Gas is the unit that measures the computational work required to process a transaction on the Ethereum network. Simple transfers use less gas; complex smart contract operations use more. The total fee you pay equals: Gas Units × Gas Price.
Since the EIP-1559 upgrade, Ethereum gas fees have two components. The base fee is set automatically by the network based on current demand — it adjusts up when the network is congested and down when it's quiet. The priority fee (or tip) is what you offer miners to prioritise your transaction above others.
The most effective strategies are: transact during off-peak hours (early morning UTC on weekdays), check current gas prices on etherscan.io/gastracker before sending, use MetaMask's gas settings to set a custom fee, and consider Layer 2 networks like Arbitrum or Optimism for smaller transactions where base fees are a fraction of Ethereum mainnet costs.
BNB Chain, Solana, Polygon, and other networks have their own fee structures, generally much lower than Ethereum mainnet. If you're doing frequent small transactions, moving to a Layer 2 or an alternative network can reduce costs by 90% or more.
