[himanshuchawla009]

• Let say if a user is connected with mainnet during login, now while using the app user wants to change the network to some other testnet , how to achieve this?

Here is an code snippet to do that:-

try {
  // here web3auth provider is the provider you get after user login with web3auth.
  await web3auth.provider.request({
    method: 'wallet_switchEthereumChain',
    params: [{ chainId: '0xf00' }],
  });
} catch (switchError) {
  // This error code indicates that the chain has not been added to web3auth.
  if (switchError.code === 4902) {
    try {
      await web3auth.provider.request({
        method: 'wallet_addEthereumChain',
        params: [
          {
            chainId: '0xf00',
            chainName: '...',
            rpcUrls: ['https://...'] /* ... */,
          },
        ],
      });
    } catch (addError) {
      // handle "add" error
    }
  }
  // handle other "switch" errors
}

Receiving this error : "0x89" is not supported, please add chainconfig for it... Should we add something else?
