When conducting a cryptocurrency transaction, a fee known as a network fee or gas fee (GWEI) is required to be paid to the miners of the blockchain network being used. These miners are responsible for verifying and processing transactions, and are compensated for their work through these fees.
The amount and method of payment for the network fee may vary depending on the specific blockchain network. Additionally, the demand for miner services, as determined by the volume of transactions on the network, can affect the cost of the network fee. It is worth noting that the USDFI protocol does not benefit financially from network fees.
