Airgap

The ultimate security for your Starknet operations

For maximum security, you can use your Argent Multisig in combination with Ledger and an air-gap device.

An air-gap device is a device kept offline (often a computer or phone with wifi and bluetooth removed) and whose isolation ensures its integrity. You can use that device to verify that the client you are using to broadcast transactions does not act maliciously.

Prerequisite:

• An air-gap device

• A Ledger device with Starknet app installed

Step 1: Set-up your air-gap device

Download the Argent air-gap script and install it on your air-gap device

Step 2: Enable air-gap support in Argent X

Go to Settings, then preferences and enable "Air Gap transaction with Ledger"

Enable air-gap in Argent X settings

Step 3: Initiate a transaction with your multisig

Air-gap support is only available on multisigs with a Ledger signer

Connect your Ledger device and initiate a transaction with your multisig. Then, before confirming, click on "Review on air-gapped device" below the transaction review. Argent X will display the transaction in the form of a QR-code.

Step 4: Verify the transaction on your air-gap device

Launch the Argent airgap script on your airgap device and scan the QR-code displayed on Argent X.

The script will decode the transaction locally and compute its hash.

✅ If both hashes are identical and the transaction review matches your intent, you can be confident that you’re broadcasting the intended transaction to the blockchain.
