While not a fee that is charged by Kraken Futures, positions opened in Perpetual contracts will accumulate a funding rate as an unrealised profit/loss (UPL) which settles every 4 hours at end of the funding period, or when you change your net open position (whichever occurs first).
This is a user-to-user transfer.
If Average Premium > 0, then for the 4 hour period, those in Long positions will continuously pay out to Short positions. This is to incentivise more Short positions, which then push the price closer to the index rate.
