Describe the Problem

I connect to Metamask successfully. However, if I switch accounts and try to connect again, the address I'm getting from signer.getAddress() is the account I initially connected with.

Code Snippet

import { ethers } from "ethers"

async function connect() {
    const provider = new ethers.providers.Web3Provider(window.ethereum, "any")
    await provider.send("eth_requestAccounts", [])

    const signer = provider.getSigner()

    const address = await signer.getAddress()

    // Always prints the the address that I first connected with
    console.log(address)
}

The .getSigner() takes in an optional address or index, which is by default 0. You should look at provider.listAccounts() to see the connected accounts.

You may need to disconnect an account to change the order, I’m not actually certain how MetaMask handles currentAccount.

A given Signer will never change its address though, as Signer is immutable. You need to use .getSigner(indexOrAddress) to attach to another account.

@ricmoo Thanks for helping out!

I think I found the issue. The first time provider.send("eth_requestAccounts", []) is called I'm prompted to selected the accounts I want to connect with:

If I choose all the three accounts, then when switching accounts getSigner() works with the currentAccount even without providing an index as a param. However, if I only choose one account in the popup shown on the screenshot, then this is the account that I will always be connected with, until I disconnect manually.

Is there a way to actually enforce showing the popup on the screenshot somehow?

[ricmoo]

Yes, listAccounts (which is used to determine the indices for the getSigner can only select from connected accounts.

I’m not sure if MetaMask offers a way to force a pop-up. If you find out though, please add it to this discussion. :)
