Ledger support: Adding Ledger to an existing multisig

Add an extra layer of security to your Argent Multisig

By adding Ledger to your Argent Multisig, you’ll combine the security of Argent and of the industry's leading hardware wallets. Trusted by the Starknet Foundation, the Argent Multisig is the go-to wallet for companies, protocols and DAOs building on Starknet.

This tutorial describes how to add Ledger as a signer to an existing multisig. If you want to create a new multisig with Ledger as a signer, please refer to this article.

! It is currently not possible to add multiple signers from the same Argent X instance to one multisig. E.g. you can’t manage a 1-of-2 multisig with 1 Argent X signer and 1 Ledger signer created in the same Argent X instance. This option will be available soon.

Before you start, you will need:

  • Argent X installed on your browser
  • A Ledger wallet (Nano X or Nano S or Nano S Plus)
  • The Starknet app installed on your Ledger, using Ledger Live (you will need to enable the developer mode in Settings > Experimental features)

Generate your Ledger signer pubkey

First, you need to generate a new signer pubkey with your Ledger device that will be added to the existing multisig.

Step 1: Join with Ledger

Open Argent X, go to accounts and add a new account. Select “Multisig Account”, then “Join existing multisig”, and then “Join with Ledger”.

Step 2: Connect your Ledger

You will be prompted to plug in and unlock your Ledger. Then, open the Starknet app in Ledger and click “Connect”. Before doing this, ensure the Starknet app is installed on your Ledger from Ledger Live.

Step 3: Generate your signer pubkey

Your signer pubkey is generated from the Ledger. Copy the signer pubkey, then click “Finish”.

You can now use your newly generated signer pubkey in an existing multisig such as described below.

Add your Ledger signer pubkey to an existing multisig

Scenario 1: Replace your current signer with Ledger yourself

[Available soon]

At the moment, you can’t replace your current Argent X signer with a Ledger signer. This feature is coming soon.

Scenario 2: Ask a multisig owner to replace your current signer with Ledger

You can ask another owner of the multisig to replace your current signer pubkey with your previously generated Ledger signer pubkey.

Ask the other owner to open the multisig account for which you want to replace your signer. Go to “Settings”, click on the account name, choose “Manage owners”, then click the settings wheel beside your name and click “Replace owner”.

Paste your previously generated Ledger signer pubkey, add a name and click “Next”.

The other owner will then be prompted to sign a transaction to replace a new multisig owner.

Scenario 3: Join an existing multisig that you don’t own

You can join an existing multisig as a new owner with your Ledger device. 

Share your newly generated signer pubkey with one of the multisig’s owners and wait for the multisig owner to add your signer pubkey to the original Multisig (Settings > Manage owners > Add/Replace owners).
