Gas Fees

Gas fees are transaction costs paid by users to compensate validators for processing operations on blockchain networks like Ethereum. Measured in gwei (a small unit of ETH), gas fees vary depending on network congestion and the complexity of the transaction. High fees can affect usability, especially for small transactions. Developers and users monitor gas prices to time their interactions efficiently. Gas also prevents network abuse by attaching a cost to each action. Scaling solutions like Layer 2 networks and Ethereum upgrades aim to reduce gas costs significantly.
