Miner fee (Gas Fee) is also known as network fee. As the name suggests, it is the fee paid to miners. When you transfer money on the blockchain, miners (or nodes) need to package your transfer transaction and put it on the blockchain , in order to complete the transaction. In this process, the computing resources of the blockchain will be consumed, so miner fees will be incurred.
In the EVM compatible chain, the fee is determined by the Gas Price (unit price) and the consumed Gas Limit (quantity), where the calculation formula is as follows: Miner fee = Gas Limit * Gas Price
The amount of Gas Limit is mainly affected by the complexity of the operation according to the content of the smart contract. The more operations, the higher the Gas limit. The gas price is set by the initiator. The higher the gas price set by the initiator, the faster the transaction it initiates can be packaged.
For example: Ethereum's network fee is ETH; Binance Smart Chain (BNBChain)'s network fee is BNB; HECO (Hecochian)'s network fee is HT; Horseshoe (Polygon/Matic)'s network fee is MATIC
If the network is not used up, it can be returned.
The miner fee (network fee) charged by the transfer network will vary according to the situation of the network. Once the transaction is confirmed, the miner fee cannot be refunded regardless of whether the transaction is successful or not.
The miner fee is charged by the transfer network you choose, and the MetaTdex wallet does not charge any fees!
