I checked your 0x3780f56e17803518ba66ec5e645a8Ea1Dabd2e89 wallet and while no transactions shows up on etherscan it says you have 197 poly or 91 dollars so import your 0x3780f56e17803518ba66ec5e645a8Ea1Dabd2e89 wallet into metamask and then click import token [![as shown here][1]][1]2 after that import this token address as it is the poly address 0x9992ec3cf6a55b00978cddf2b27bc6882d88d1ec [![like this][2]][2] and click importadd custom token and you should be ready to go [1]: https://i.sstatic.net/EXirO.png [2]: https://i.sstatic.net/NP2mh.png as
as for the other wallet address, it should be the same steps but it says you only have 3 cents worth of poly and when I call the contract function of Idex balanceOf and input 0x4ad0fb0672cbb9ef788a134522b0caefaa9dbb7f andand input the poly token address it says you have 0 poly in their contract so I'm not really sure about that wallet hope this helps best of luck
