Network Fee: Why Is It Dynamic?

3 min readApr 13, 2023

In cryptocurrencies, unlike traditional currencies, there are several aspects to consider when conducting transactions. One of them is the network fee the user pays for processing and confirming the transaction. In this article, we look at the basics of network fees and their importance for blockchain networks.

Key takeaways:

  • Network fees in cryptocurrencies are commissions paid for transactions on the network.
  • High fees can lead to delays in transaction processing and increases in the overall cost of the operation.
  • Fees do not depend on the transaction amount.

Network fees are charges users pay for processing and confirming transactions on the blockchain. Each chain has its own way of calculating fees, but the main factors influencing fee size include:

  • Network congestion: when the network is congested, transaction processing takes longer, and users have to pay more to have their transactions processed faster.
  • Transaction size: fees also depend on the transaction size in bytes. The more data needs to be processed, the more computational power and time will be required to complete the transaction.
  • Priority: users can set transaction priority to get quick confirmation. Such a choice increases the fee cost, but allows quick confirmation.

Ethereum Network Transaction Fees

The Ethereum network fee changes every second and is always different. Just like you pay a wire or ACH fee when transferring money out of your bank account, there is a fee (called a gas fee) to send transactions on Ethereum. Gas is a unit of measurement that determines the cost of each operation on the network. The gas price is denominated in Gwei, equal to 0.00000001 ETH.

To calculate the gas fee, multiply the gas limit by the gas price per unit. For example, if the gas limit is 20,000 and the price is 200 Gwei per unit of gas, then the fee would be calculated by multiplying 20,000 by 200. This equals 4,000,000 Gwei or 0.004 ETH.

Users can specify how much ETH they are willing to pay for a transaction to increase its processing priority. The more gas required to execute a transaction, the higher the fee will be.

Why do they exist?

Network fees are necessary for maintaining network security and preventing attacks such as DDoS. In addition, they are necessary for paying overhead costs to validators or miners who participate in verifying and confirming transactions with digital assets.

0xprocessing supports several networks, including Bitcoin, Ethereum, Tron, BNB Chain, Avalanche C-Chain, Solana, and others. It should be noted that each of these networks has its own characteristics and differences that should be noted:

As shown in the table, each network has its unique characteristics and advantages. Ethereum is the most popular and widely used network, but fees can be quite substantial, especially during periods of high network traffic. Tron has high transaction speeds and low fees, making it an attractive choice for some users. BNB Chain offers low fees and efficient throughput, while Avalanche C-Chain and Solana provide excellent throughput and speed.

Therefore, the choice of a suitable network depends on the specific needs of the user and the nature of their transactions. provides the opportunity to work with different blockchains, allowing users to choose the most suitable currency and network in each specific case. Don’t forget to consider the dynamic nature of fees when conducting payment transactions and keep an eye on their changes depending on the market situation.
