I'm trying to use `heimdallcli` within my local dockerized network that I set up using `matic-cli`. My main goal is to send a proposal using this command: `heimdallcli tx gov submit-proposal param-change {pathToProposalJSONFile} --validator-id {validatorID} --chain-id {chainID}`. However, I'm encountering an error that states: 'Config File "heimdall-config" Not Found in "/var/lib/heimdall/config"'. The config directory doesn't seem to exist in the Docker environment, though I can see logs that suggest Heimdall is functioning. How can I resolve this and get the `heimdallcli` command working?

I'm struggling to sync my node correctly. I received a warning about synchronization failure due to whitelist validation. Also, I was informed that a remote peer doesn't have a target block number as the last white-listed block number. Could someone share the most recent enode list or help me troubleshoot this sync issue?

How to update or get the latest working enode list?

I recently tried swapping XSGD (Polygon) to USDC (Polygon) using 1inch and accepted a smart contract. I set an approved limit of 500 XSGD, swapped the full amount, but now want to know how to locate and potentially revoke the contract if needed. I've used tools like unrekt and revoke but can't find any contracts in my wallet. How does one usually approach revoking such smart contracts?

How are validator rewards calculated on Polygon network?
