Took gas fees but did not take USDC?

Confused here. Tried zap and hit “approve” and it said “completed.” But all it did was take the gas fees and left the USDC in my wallet. I was not given any YLA. And by “nearly zero gas fees” does that mean several $8-9 worth?

you need to press “supply” after approving your tokens.
Approve is just a permission, not the actual supply/deposit transaction. Plz refer to this guide:

Thanks a lot for this!

You could spend $500-800 for direct supply in YLA.
