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 to revoke a 1inch swap contract for XSGD to USDC?

Can someone help clarify this for me?

How are validator rewards calculated on Polygon network?

I'm running a node and I've noticed that my transactions are always included two blocks later rather than in the next block. I've checked online and found others with the same issue but no answers. Could it be due to peer connection problems? I even streamlined to new block creation, but the latency still results in my transaction entering in block n+2. Does anyone know why this is happening?
