Starting from the Zks group telegram I found a forum about this V3 testnet…
You know I’m a new user in this zkswap group, so I don’t really know much about this V3 testnet, first I was confused about how to enter to try this V3 testnet, thanks to the group admin’s help, I was finally able to do this test, starting from logging in using the Metamask wallet, until I entered the transaction in this V3, first for the swap that I did using the faucet claim balance, it was very smooth and easy because I’m used to doing swaps like in a trust wallet, but in this V3 through Metamask I think it’s better and easier, than swap very easy trade and swap pool. Now for the NFT transaction, I’m confused again, I asked the group admin again, how to make NFT, how to sell to how to buy, all of that really confused me, because I’m a new user, but finally I was able to print NFT for me to sell at a cheap price, and finally it was sold, after that I tried to buy the NFT I chose the cheapest, and finally I was able to buy it with a very easy payment…my experience using V3 was very smooth and easy after being directed by the admin everything went smoothly, thank you admin
zkswap …my opinion for this testnet is very interesting, anyway good.
my advice…! → for new users like me, don’t hesitate to ask the group admin, what the problem will definitely be helped well… I hope that when the actual V3 launch will be better than this testnet… 
Good luck for V3.
