The method 'wallet_switchEthereumChain' does not exist / is not available.

Description

I am attempting to claim some rewards from https://cryptomeda.tech/staking and keep getting this error: The method 'wallet_switchEthereumChain' does not exist / is not available.

I talked with their support and they said to use chrome instead. I don't want to use chrome 😉

wallet_switchEthereumChain comes from EIP-3326

• https://docs.metamask.io/guide/rpc-api.html#wallet-switchethereumchain
• https://eips.ethereum.org/EIPS/eip-3326

Steps to Reproduce

From Console run something like this:

await ethereum.request({
    method: 'wallet_switchEthereumChain',
    params: [{ chainId: '0x89' }],
  });

Actual result:

Brave version (brave://version info)

Are you using Brave Crypto Wallet Extension or MM? I don't believe we have support for EIP-3326 on our wallet extension.

I am using the Brave Crypto Wallet Extension.

Is there someplace better where I can request adding support for this?

[srirambv]

We can use this issue itself as feature request

[onyb]

I confirm that we currently do not support EIP-3326 in the wallet extension. We have added this to the roadmap of our native wallet which is coming out soon and will eventually replace the wallet extension. You can track its progress on our project board.
