Nice work. I have not explored any of the other chains and I have WAX on my list for later this year. Interesting to know about Polygon.
How about the transaction fees? Are the gas fees insane like ETH? That's one biggest advantage here. People don't have to pay insane gas fees to transfer the NFTs because transactions are free here.
I will write a blog about my experience when I have minted and sold my first batch. The site's documentation mentions that gas fees are only paid when bridging your ETH to Polygon to turn some of it into Polygon ETH, and also when sending your earnings to Ethereum Mainnet to convert it back to regular ETH. You cannot use Polygon ETH outside of its Polygon/MATIC ecosystem as you would with regular ETH.
Okay nice at least better than dealing with ETH completely.
