The problem

When using the Wallet_addethereumchain RPC Function in a metamask Android app The chainid property of the Ethereum network object returned by this function is crucial for proper identification and management of custom networks.

. Specifically, it says “wrong chain ID”. This suggests that there might be an issue with how you

Code Review

Let’s Take a Closer Look at Your Code Snippet:

`JavaScript

Const Chain = Await Provider.getchain (“Customnetwork”);

Const chainid = chain.chainid;

Wallet_addethereumchain ({

Network: Chain,

from: Accountaddarress,

});

`

Notice that we are passing the chainid as an argument to thewallet_addethereumchain function. However, in your code, you are only pass the Custom Network Object Directly:

`JavaScript

Const Chain = Await Provider.getchain (“Customnetwork”);

`JavaScript

Const Chain = Await Provider.getchain (“Customnetwork”);

Const chainid = chain.chainid;

Wallet_addethereumchain ({

Network: Chain,

from: Accountaddarress,

});
