How to get network name and chain Id to which metamask wallet is connected using Ether.js library?

[DeadmanAbir]

Hey I am looking for a solution that I would use in my Dapp to get the network name and the chain Id of the network to which the wallet is connected using Ether.js library.

For eg- If my wallet is connected to goerli network then I should get network name as goerli and chain Id as 5. What would be the code for that?

hey @DeadmanAbir to get the chain ID try this:

const { chainId } = await provider.getNetwork()
console.log(chainId) 

or this would work as well

provider.getNetwork().chainId

for getting the network name, try this.

getNetwork().name 

Let me know if this work.

Bro it's giving error. By going through the documentation I got to know that we have to write the network name inside the getNetwork() like ethers.provider.getNetwork("goerli") but in this case we have to know the network name but what if I don't know the network name and still want to get the chain Id?

hey @DeadmanAbir try this one , It is working for me here on my system it'll work on yours too. Try this ;
before doing anything make sure first to import network from hardhat like this.

const {network} = require("hardhat");

and then in your async function type this.

const network_name = network.name;
console.log(network_name);
const chainID = await network.config.chainId;
console.log(chainID);

it will spit out the network name and chainId on the console.

bro you r using hardhat but in Front-End I can't use this as it was not a hardhat project, so I need the ether.js version
