Hi. 0x Team.

I am developping Dex using 0x API.

I have approved both of proxy contract and exchange address, and I have enough balances.

Please let me know what’s wrong and how to fix it.

Thank you.

hi Kevin, I suggest you post
The forum is mostly for governance and research topics.
I’d suggest to check again the decimals of the token you’re trying to exchange (I checked the address and it didn’t seem to have enough ETH/WETH)
Also looks like you were able to transact once?
