A gas fee is the cost of processing a transaction or running a smart contract on a blockchain, paid to the network's validators.
When a network is busy, users compete to have their transactions included, driving fees up. Quiet periods mean lower fees.
Fees depend on the network's demand and the complexity of the transaction. Simple transfers are cheaper than complex smart-contract calls.
Transact during off-peak times, use layer 2 networks, and avoid complex operations when fees are high.
Gas fees are a real cost of using blockchain networks, and understanding them helps you avoid overpaying.
Gas fees are the price of using a blockchain. Timing and network choice are your best tools for reducing them.
