Hey @grenade thanks for the PR. I'll have a run at this soon, just to verify, but from a quick glance it looks good. Youll just have to run build.sh file inside of /<ROOT>/calc

thank you! i've actually not been able to prove this works yet (hence the draft pr).
https://api.serrano.calamari.systems/blocks/311056 is running the version of code in this pr but still shows "Fee calculation not supported for this network" so i'm still trying to work out why the fee calculation doesn't appear to work.

Is there a public node I can test this against?

Could you provide me with a block number/hash that contains an extrinisic that would require a fee as well?
Feel free to run yarn lint --fix for the linter as well
