What is Gas Fee?

A gas fee is the cost of getting a transaction included and executed on a blockchain. It pays the validators or miners who process the work and is charged in the network’s native token. Fees rise when the network is busy and fall when it is quiet, because block space is limited and demand-driven.

This matters for reward seekers because gas is a real cost that can eat into small rewards. Claiming a tiny airdrop during a period of high fees might cost more than the airdrop is worth.

Example: sending a token on a busy network might cost a few dollars in gas at peak times but only cents during a quiet stretch, even though the transaction is identical.

Safety note: always keep a little of the native token in your wallet to cover gas, or you cannot transact. Be wary of scams that ask you to send “gas fees” or a “deposit” to a personal wallet to unlock rewards, since real gas is paid to the network, not to a person. Related terms include gas, gwei, gas limit, and mainnet.
