I believe I only cover SPT on the front end that I used. As for Axie, you still retain ownership of the NFTs as most assets are now kept on the Ronin sidechain. They do not take half for sales but rather a flat 4.25% fee which is fair and roughly half the price of sales on Opensea. Axie Infinity and Splinterlands are both great games with little competition in the space and I'm glad to have exposure to both.
