Ethereum, like any other blockchain, has fees associated with each transaction that is processed on the network. These fees are necessary to incentivize the miners who validate and confirm the transactions that take place on the Ethereum network.
The fees charged for each transaction are typically very small, and are measured in “gas”. The gas prices are set by the miners, and can fluctuate depending on the network conditions.
When demand is high, the gas prices will increase, and when demand is low, the gas prices will decrease.
The amount of gas that is required for a transaction to be processed is dependent on the complexity of that transaction. A simple transfer of ETH from one address to another will require less gas than a contract deployment or a token transfer.
The sender of a transaction is responsible for paying the gas fees associated with that transaction. The gas fees are paid in ETH, and the amount of ETH that is paid is determined by the gas price and the amount of gas required for the transaction.
One important thing to note is that the sender of a transaction is not charged any fees if that transaction fails or is rejected by the network. This means that there is no risk associated with sending a transaction on Ethereum, as long as you are willing to pay the gas fees.
In conclusion, yes, Ethereum does have fees associated with each transaction. These fees are necessary to incentivize miners and cover the costs of running the network.
The sender of a transaction pays these fees in ETH, and they are determined by the complexity of the transaction and the current gas prices.
