Thanks! it was a typo. Fixing it now.

Ok, try a global replace, I saw it in other sites as well :slight_smile:

I’m confused about why the eth_gasPrice call returns 0. Should I just hardcode 1Gwei then? What’s the reason for eth_gasPrice not working?

eth_gasPrice is a analytical function and is not working well with fast and empty blocks. I’d consider to hard code 1 Gwei for now. We plan to implement better support of the gasPrice oracle in the future.

Awesome, thanks. Will hardcode for now.
