Metamask Wallet: Error adding Ethereum chain: Incorrect chain ID
As a developer, you have probably encountered issues integrating MetaMask into your application. Android to add custom Ethereum networks via the RPC function wallet_addEthereumChain. In this article, we will dig deeper into the issue and provide solutions to fix the incorrect chain ID issue.
Problem
When using the RPC function “wallet_addEthereumChain” in a Metamask Android app, it is essential to ensure that the added network is correctly identified by the wallet. The “chainId” property of the Ethereum network object returned by this function is crucial for correctly identifying and managing custom networks.
Error
In your case, the error message indicates that the chain ID returned by Metamask is incorrect. Specifically, it says “incorrect chain ID”. This suggests that there may be a problem passing or accessing the “chainId” property when adding the custom network to the wallet.
Code Review
Let’s take a closer look at the code snippet:
const Chain = await Provider.getChain("customNetwork");
const chainid = Chain.chainId;
wallet_addEthereumChain({
network: chain,
from: account address,
});
Note that we are passing “chainId” as an argument to the “wallet_addEthereumChain” function. However, in your code, just pass the custom network object directly:
const Chain = await Provider.getChain("customNetwork");
wallet_addEthereumChain({
from: account address,
});
As we can see, when adding the custom network to the wallet, you are passing an empty “{}” object instead of “chainId”. This is probably causing the wrong chain ID issue.
Solution
To fix this issue, make sure you pass the correct “chainId” value when calling “wallet_addEthereumChain”. Here is an updated code snippet:
const Chain = await Provider.getChain("customNetwork");
const chainid = Chain.chainId;
wallet_addEthereumChain({
network: chain,
from: account address,
});
Additional Tips
To ensure proper identification of custom Ethereum networks, make sure to:
- Verify that the “chainId” value is correct and matches the expected ID for your network. personalized.
- Test your addEthereumChain RPC wallet with different custom networks to identify any issues.
- For instructions on adding custom Ethereum networks, see the Metamask documentation and community resources.
By following these steps, you should be able to resolve the incorrect chain ID issue and successfully integrate your custom Ethereum network into your application. Android uses MetaMask.
