              Arbitrum Gas fee suggested by MetaMask is a lot far from the Gas fee actually charged by the network. For example, the attached image shows a current transaction of mine in which the Gas fee suggested by MetaMask is above 2.1 dollars. However, the gas fee charged was around 10 cents. It is usually a few cents these days on Arbitrum. I think that the Priority fee should be set to zero in MetaMask, as Arbitrum does not charge the priority fee.

              Great! I have seen many MetaMask users got confused these days by the estimated Gas fee on Arbitrum after the Nitro upgrade.

    ## Background
Arbitrum will require accepting of [0 priority fee](https://con… sensys.slack.com/archives/C026U6QPYAC/p1660800748283659) for their Arbitrum Nova and Arbitrum One. In Arbitrum, transactions get through in a FIFO manner, so users don’t need to provide any priority fee. Also, the block base fee is low in typical non-congested L2 situations. [Gas API changes](https://consensys.slack.com/archives/C026U6QPYAC/p1662011192663949) to reflect this have been coded up, frontend changes need to follow suit to reflect the backend changes.
We should implement front-end logic to match the backend -- if network is Arbitrum, then remove the Max priority fee must be greater than 0 GWEI warning, and allow users to enter 0 as priority fee. 
## Acceptance Criteria
1. When the user changes the network to Arbitrum, set default max priority fee to 0
2. Remove the Max priority fee must be greater than 0 GWEI warning
3. Disable editing of max priority fee
4. Allow submitting of transaction of 0 max priority fee

              Hey, thank you so much for the feedback! So MM manage to fix $1-$2 fee amount just by removing priorityFee?
