I tryed different contract addresses and keep getting this error:
"This contract has errors. Some ABI functions have incorrect format. Please input another address"
As the result suggest, it seems your contract has an incorrect format and therefore his apps can't return the output. It would be glad if it shows which one is incorrect.
The OP apps, at this initial stage, more or less looks like Etherscan read function, but we can't interact with it yet (can't query balanceOf, etc). Nice apps, looking forward to further development.
Thanks for the feedback. I will work and develop.
