On both sides of the rental transactions things can now be automated.
So you can setup a bot with splintermate for $1 per month and set up rental groups in the tool to automatically rent cards. Even related to the focus quest of the day.
On the other side you can rent out cards automatically with splex.gg, which will constantly try to optimize the rental prices for your cards.
Finally, it has become a lot more common to rent only for a couple days and to cancel rentals after a couple days, in order to raise the rental price when the end of the splinterlands season is coming closer
