For `BTC`, it is specified in `sat/vByte`; for `LTC` and `DOGE`, it is in `sat/Byte`. For `XMR`, an integer (1-4) is passed to set the transaction priority: `1` - Unimportant, `2` - Normal, `3` - Elevated, `4` - Priority. For other cryptocurrencies, any value can be passed, the optimal fee is calculated and set automatically, and this field is ignored.
