Crypto gas fees serve as the backbone of blockchain networks like Ethereum. Users encounter these fees whenever they send tokens or interact with smart contracts. The fees compensate validators who process transactions and secure the network.
Every blockchain operation requires computational resources. Simple transfers can use around 21,000 gas units, while complex smart contract interactions demand significantly more processing power.
On Ethereum, fees are quoted in “gwei,” one billionth of an ETH. The total transaction cost is the result of multiplying the gas units by the current unit price. Most wallets automatically calculate this for users.
