Describe the bug

wallet_addEthereumChain does not seem to work any more.

Example code:

  window.ethereum.request({
      method: 'wallet_addEthereumChain',
      params: [{
        chainId: '0x64',
        chainName: 'Gnosis Chain',
        nativeCurrency: {
          name: 'xDAI',
          symbol: 'xDAI',
          decimals: 18
        },
        rpcUrls: ['https://rpc.gnosischain.com/'],
        blockExplorerUrls: ['https://gnosisscan.io/']
      }]
    });

Error:

{
    "name": "Error",
    "message": "Error JSON PRC response: the method wallet_addEthereumChain does not exist/is not available",
    "stack": "Error: Error JSON PRC response: the method wallet_addEthereumChain does not exist/is not available\n    at parseRPCResponse (chrome-extension://jnmbobjmhlngoefaiojfljckilhhlhcj/background.bundle.js:8:3585179)\n    at chrome-extension://jnmbobjmhlngoefaiojfljckilhhlhcj/background.bundle.js:8:1453930\n    at Array.map (<anonymous>)\n    at ServiceDApp.<anonymous> (chrome-extension://jnmbobjmhlngoefaiojfljckilhhlhcj/background.bundle.js:8:1453890)\n    at Generator.next (<anonymous>)\n    at asyncGeneratorStep (chrome-extension://jnmbobjmhlngoefaiojfljckilhhlhcj/background.bundle.js:8:11373261)\n    at _next (chrome-extension://jnmbobjmhlngoefaiojfljckilhhlhcj/background.bundle.js:8:11373506)"
}

To Reproduce
Go to console and execute the above code or the sample code in your repo.

Expected behavior
This will prompt the "Add chain to wallet" window to appear.

Screenshots
The video below demonstrates me: 1) successfully using the same code to bring up Rainbow Wallet; 2) attempting to use the same code but failing to bring up OneKey Wallet.

Additional context
I have just tested the Chrome extension. Some users are reporting that they are unable to do the same in the app too.

edit: I was trying to make a PR to fix this but found this endpoint is not open source? Btw, you should definitely fix the disturbing PRC typo.

There are no plans to support wallet_addEthereumChain in the near future.

[Songkeys]

Is there a public announcement available regarding this decision? Without it, users could become confused and our dapp developers might face inconvenience and queries from users.

By the way, I came across a tweet from the official Onekey account mentioning that it will be addressed in the upcoming version. Which statement is accurate? https://x.com/OneKeyCN/status/1829383704923496802

[ByteZhang1024]

We will do it, but not that quickly. This adjustment is a very significant change.
You can first explain your requirements and which networks you need. We can initially embed them in the app.

I see.

I am a developer from @RSS3-Network. Our users are experiencing issues connecting to our chain using OneKey while they reported they could do so a while ago. If possible, could you kindly embed the rss3 chain in the app? Thank you!

You can find the chain config here:

• mainnet:https://github.com/wevm/viem/blob/main/src/chains/definitions/rss3.ts
• testnet: https://github.com/wevm/viem/blob/main/src/chains/definitions/rss3Sepolia.ts

[ByteZhang1024]

If you need to transfer any assets, you can use https://app.onekey.so/ for now.
The requirement has been reported, and we will process the addition of the RSS3 network as soon as possible.
