I find it challenging doing galxe task and claiming the OAT with my APTOS wallet until recently.
Over time, I have avoided doing galxe task with my APTOS wallet for 2 reasons;
!. When I tried to claim OAT after completing the task using my EVM (Metamask wallet), I will ask me to switch to APTOS chain, When I switched, it will ask me to bing my wallet bujt whenever I bind it, the wallet binding feature failed to give me the option to use my APTOS Martian wallet. So for that reason, I simply ignore the task and move on.
Secondly, when it eventually started working, there is no Martian wallet like I have said, only Petra and Fewcha wallet, so I get lazy with importing my Martian wallet to either of these two (2)
Sp do do galxe task on APTOS network, for the meantime, I suggest you download Petra wallet extension if you are just creating your APTOS wallet for the first time. If you already have an APTOS wallet, I will suggest you import it to Petra or Fewcha. I used PETRA though.
Next, bind your APTOS wallet by clicking Menu, select settings and then select wallets. Scroll down and you will see the option to select the network you want to b ind wallet for. Choose APTOS.
Petra and APTOS will popup for you, choose the one you prefer and wait for your
wallet to popup, click connect and sign the transaction to bind your wallet.
I will suggest you first complete all the galxe task you wanted to do with your EVM wallet, then disconnect the EVM and bind your APTOS wallet.
Once you have bounded your wallet, you will see claim OAT or NFT below the Task page if you are on the APTOS network on the galxe page.
If you are not, then change your network to APTOS and claim.
Good luck
