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](https://www.argent.xyz/blog/ledger-argent-integration/) ### Step 1: Set-up your air-gap device Download the [Ready air-gap script](https://github.com/argentlabs/x-airgap) and install it on your air-gap device ### Step 2: Enable air-gap support in Ready Wallet Go to Settings, then preferences and enable "Air Gap transaction with Ledger"

### Step 3: Initiate a transaction with your multisig {% hint style="info" %} Air-gap support is only available on multisigs with a Ledger signer {% endhint %} 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. Ready Wallet will display the transaction in the form of a QR-code.

### Step 4: Verify the transaction on your air-gap device Launch the Ready airgap script on your airgap device and scan the QR-code displayed on Ready Wallet. 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.
