A gas fee is a network transaction fee required to conduct transactions or execute programs (smart contracts) on a blockchain.
Think of it like a bank transfer fee. In the blockchain world, this fee is paid to the individuals (validators or miners) who verify and record transactions as compensation for their computing power.
Gas fees are also proportional to the computational complexity of the action. A simple transfer of crypto requires less gas, whereas a complex calculation like staking requires more.
Payment via Native Tokens
Gas fees must always be paid using the "native token"—the specific cryptocurrency built directly into the foundation of the blockchain network you are using.
- Ethereum Network: Paid in ETH
- BNB Chain (BSC): Paid in BNB
- Polygon Network: Paid in POL
Important Note:
Even if you are transferring other tokens (such as USDT or JPYC) on the Ethereum network, the transaction fee must still be paid in the native token, ETH, rather than the token you are sending. If your wallet lacks the necessary native token to cover the gas fee, the transaction cannot be processed.
Why Gas Fees Fluctuate
Gas fees consist of two parts: a Base Fee that automatically adjusts depending on network traffic, and an optional Priority Fee (Tip) that you can add if you want your transaction processed faster.
When the network is congested, the base fee automatically goes up; when traffic drops, the fee goes down. If you are in a hurry, paying a higher tip helps ensure your transaction is processed with higher priority.
Tip:
Fees tend to spike while North American markets are active and open. If your transaction is not urgent, try timing it during quieter hours to save on fees.
