Gas Fees

Gas fees are transaction costs paid to blockchain validators for processing transactions. Ethereum gas fees fluctuate based on network demand and can range from $0.50 to $100+ during peak congestion.
Gas fees are the cost of executing operations on a blockchain. The term originated with Ethereum, where every operation in a smart contract consumes a measured amount of "gas," and users pay for that gas in ETH.
How gas works on Ethereum: - Gas limit: the maximum amount of computation a transaction can use - Base fee: algorithmically determined by network demand (burned via EIP-1559) - Priority fee (tip): optional extra payment to validators for faster inclusion - Total cost = gas used × (base fee + priority fee)
Gas fees fluctuate dramatically: - Low demand: $0.50-$2 per transaction - High demand: $50-$100+ per transaction - During NFT mints or market crashes, fees can spike to $200+
Strategies to minimize gas: - Transact during off-peak hours (weekends, early morning UTC) - Use Layer 2 networks (Arbitrum, Optimism, Base) for much lower fees - Batch transactions when possible - Set gas limit appropriately to avoid overpaying
Other blockchains (Solana, Avalanche, Polygon) offer much lower fees — typically under $0.01 per transaction — which is why some DeFi activity has migrated away from Ethereum mainnet.

Ethereum (ETH)
Ethereum is the second-largest cryptocurrency and the leading smart contract platform. It enables decentralized applications (dApps), DeFi protocols, and NFTs through programmable smart contracts.
Smart Contract
A smart contract is a self-executing program stored on a blockchain that automatically enforces the terms of an agreement when predefined conditions are met, without needing a middleman.
Layer 2 (L2)
A Layer 2 is a secondary blockchain built on top of a main chain (like Ethereum) to process transactions faster and cheaper. Popular L2s include Arbitrum, Optimism, and Base.
