Around November of last year, the Play-to-Earn game, CryptoRoyale.one hosted a weekly tournament, with prizes from another Harmony project - Kuro Shiba, $KURO.
$KURO is a project on the Harmony block-chain that aims to bring not only amazingly cute artwork from their wonderful artist, persimberry, but also allows you to put that artwork, and your NFTs to work.
They have been hard at work bringing about their "Exhibitions" page, a place where you can stake your NFTs from the Harmony Network, and earn rewards from that.
For example, $KURO recently partnered with another Harmony project - Cerebral Gaming DAO. I minted three, NO. 3 CGD NFTs for a price of 10 $ONE each here: https://mint.cerebralgaming.one/ or about $2. I then went to https://www.kuroshiba.one/ under the "Exhibitions" page, and you have an option to then stake these NFTs.

You first need to "Approve Admission Fee" which costs some $ONE in gas. You then need to approve the staking fee, of 3,500 $KURO. Once you completed this, you can stake your NFTs and, at least in the example - earn 0.055 $CGD every day. I've staked three of them - so I'm currently earning 0.165 $CGD a day.
You can also, at the moment, stake Dingos Bowl Club NFTs to earn ~100 $xDG (xDingo) per day, or Harmony Whales to earn 1 $ARB (Arbiter) per day.
This is the first step in $KURO's process, and they are still testing and tightening all the bolts, but the team has done a lot of hard work and projects keep flocking to them to work with. I'm excited for when they bring their own Liquidity Pools and farms into the space through their "Fish Ponds", and their "Night Market" where you'll be able to trade, buy, and sell NFTs for and with $KURO.
Make sure you check them out and give the team the credit they so rightly deserve!
