Can we bridge between Mumbai and Amoy testnets?
I've been working on a project and am a bit confused about the Mumbai and Amoy testnets. Are they the same thing? If not, is it possible to bridge between these two testnets?

Using heimdallcli in a dockerized local network setup?
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?

Groth16 proof verification cost on Polygon vs Ethereum
I've been trying to figure out the gas cost for verifying a Groth16 proof on the Polygon network. On Ethereum, it is around 250k gas. With my estimation using a gas price of 100 gwei, this would imply around 0.025 POL cost on Polygon. Can anyone confirm if this estimation or cost difference is accurate?

How to store more than 128 blocks worth of data in Bor?
I am currently trying to store a month's worth of data when running Bor in full mode, but I can't exceed 128 blocks. Can I change settings or run archives to get around this limit and retain about 30 days of data?

Why is Polygon POS Node setup taking so long to download snapshots?
I'm trying to set up a Polygon POS Node and downloading the most recent bor snapshots seems to be taking hours. I have a server with 32 cores, but the full process is still slow. Is this normal, and what factors could be affecting the download time?

How to fix 'Head state missing' error in Bor node?
Hey folks, I just ran into an issue with my Bor node today. It's not syncing currently and I'm seeing the error: 'WARN [03-13|16:26:04.518] Head state missing, repairing'. I was previously synced up until today. I'm running a mainnet node, and I need to figure out how to fix this. Can someone please help?

Where to find info on Amoy explorers and EntryPoint contracts?
So, I'm trying to dive into the Amoy network and need some guidance. I'm looking to see if there are any explorer tools available for Amoy because I can't find anything on Polygonscan directly. Also, I'm hunting down the EntryPoint contract deployment on Amoy, like what versions are there and what their addresses might be. Lastly, I'm curious about the metadata for Amoy, specifically the chain IDs for Amoy and Amoy Matic. Any insights?

How to maintain a fast and reliable Polygon node sync?
I'm trying to maintain my Polygon node to work all the time and ensure fast sync speeds. I have set the maximum peers to 150, but I'm only getting around 120 after a week. I restart my node occasionally and want it to be as close to validators as possible. I already have a few nodes but need more trusted nodes for better sync performance. Could anyone share some good enodes or advice for improving sync speed?

How to add your token to Polygon Portal bridge?
Hi everyone! I've deployed my token on the Polygon POS network, but I'm looking to bridge it through the Polygon Portal bridge. I was wondering how I can add my token to the bridge? Initially, I thought all bridges would just handle deployment for me, but from what I understand, the bridging might only work with tokens originally deployed on Ethereum. Any tips on how this process works would be much appreciated!
