Hey @miohtama, it looks like the example env file contains the config for running the interface against a fork. Try deleting these lines from your .env:

NEXT_PUBLIC_FORK_BASE_CHAIN_ID=1
NEXT_PUBLIC_FORK_CHAIN_ID=1
NEXT_PUBLIC_FORK_URL_RPC=https://rpc.tenderly.co/fork/1234567

We could probably update the readme to make that clear
