For custom fee type should be specified fee-rate and also priority-fee for Ethereum network.

Parameter	Type	Description
`fee-rate`	integer	The parameter is only used when `fee` is set as to `custom` fee. For example: for Bitcoin the value is specified in satoshi per byte (sat/byte). Example: fee-rate = 3 means 3 satoshi per byte. For Ethereum: the value is specified in gwei. Example: fee-rate = 20 means 20 gwei per gas (how the fee works in Ethereum and what it consists of you can see here (opens new window))

Parameter	Type	Description
`priority-fee`	integer	Defines the priority fee (also known as the "tip") that is paid directly to Ethereum validators to incentivize transaction inclusion. When this field is used, its value is added to the `fee-rate`. This field is only applicable when the `fee-rate` is specified.
