    - For UTXO-based assets, the response contains the `feePerByte` parameter
    - For ETH-based and all EVM based assets, the response will contain `gasPrice` parameter. This is calculated by adding the `baseFee` to the `actualPriority` based on the latest 12 blocks. The response for ETH-based  contains the `baseFee`, `gasPrice`, and `priorityFee` parameters.
    - For ADA-based assets, the response will contain the parameter `networkFee` and `feePerByte` parameters.
