Hi Team,

I am getting JSON RPC Error but this issue is only on Base network. I’ve checked the RPC link which i added. It was working great from months but now suddenly getting error whenever i try to do transaction. How to resolve this?

Hi @cab00676,
Does this occur on mobile? If yes, check the Chain ID also, make sure its 8453.

No, Its on Brave browser on macbook. Checked different RPCs as well as the Chain ID. Everything is OK… have lodged this issue in MM tickets. They’re investigating.

Allright then. In the meantime you can also remove the network and add it back again, see if that works.

Yes, Done that multiple times but still was facing the issue. Seems like have to create other wallet to do base network activity :frowning: unless MetaMask team come with any resolution.

@cab00676,

Have you added another RPC for the Base network? If not, please add an appropriate RPC from the following link. Click on the small arrow at the bottom of the Base network box and add another RPC to your MetaMask wallet.

I’ll take a look if you can provide your address. If that is not something you feel comfortable with then please try to following:

  1. Check your address on basescan and find the latest succesful transaction executed by you. Find the nonce of that and add 1 to it. I.e. if the nonce of the latest TX you executed (not ingoing transaction) is 10 then we will use nonce 11.
  2. Use the custom nonce method explained here: How to speed up or cancel a pending transaction | MetaMask Help Center 🦊♥️
  3. Make sure to manually edit the gas fee before self-sending. Set it to 0.2 GWEI.

Keep me updated.

Hi @dcacryptodaily,

This issue is usually related to the RPC. The following steps can help you.

  1. Make sure that the network has been added correctly. You can add another RPC for the same network to your MetaMask using the following link.
    https://chainlist.org/
  2. Make sure that you have enough native tokens for the same network to pay the gas fee, i.e., make sure to have enough ETH on the Base network.
  3. Make sure that both the browser and your MetaMask are the latest versions.

Hope that helps.
