What Are Gas Fees in Web3?
Gas fees are the transaction costs required to perform operations on blockchain networks. When you send cryptocurrency, execute smart contracts, or interact with decentralized applications (dApps), you pay gas fees to network validators who process and secure your transactions.
Gas prices are measured in Gwei (1 Gwei = 0.000000001 ETH) and fluctuate based on network congestion. The Ethereum gas tracker on Gas-Web3 helps you monitor these prices across multiple blockchains, so you can time your transactions when fees are lowest.
Different networks have different fee structures: Ethereum gas tends to be higher during peak times, while Polygon MATIC gas and BNB Chain gas fees are typically lower, making them popular alternatives for cost-effective transactions.

Understanding Gas Fee Levels
Gas-Web3 categorizes gas fees into three levels to help you make informed decisions:
Slower confirmation, lowest cost. Best for non-urgent transactions like token transfers or NFT minting.
Balanced speed and cost. Recommended for most transactions including DeFi swaps and standard transfers.
Fast confirmation, highest cost. For urgent transactions like time-sensitive trades or priority operations.
💡 Pro Tip: Gas prices are measured in Gwei (1 Gwei = 0.000000001 ETH). Costs shown are estimates for standard transfers (21,000 gas limit).
