Checking approvals #51

Closed cloudonshore closed 5 years ago

cloudonshore commented 6 years ago

Hello, I was wondering if you were aware of any contracts that would allow me to check ERC20 approvals (allowances) for multiple addresses/tokens in a single call. Thanks so much for your great work.

In case you or anyone else still needs this. I published a contract that also allows this Here.

Will add this to the website for exchanges like 0x soon. For now you could try interfacing with the contract either manually on etherscan 'Read Contract' or in your own code. function tokenAllowances(address spenderContract, address user, address[] tokens)
