Thanks for the delivery @ramilexe I started my evaluation, please see the document to look at the errors I'm getting, I'm having issues due to the .env file. The .env sample in the readme is different from the actual .env.sample file. Which one should I be copying? (neither work because there is no actual network info). Also, what should I be entering for POLKADOT_CONTRACT_ADDRESS=<Polkadot contract address> I'm not sure how this would be used since Polkadot relay chain doesn't run smart contracts.

I would think the .env example should provide some RPC nodes to connect to? Should I be running the backend while running the tests?
