ICP staking with seed phrase and air-gapped computer

Requirements

You can only stake with seed phrase and air-gapped computer if you are already doing ICP custody with seed phrase and air-gapped machine. This page assumes you are successfully doing self-custody of ICP as in that page.

This section assumes you successfully installed the QR tools on your air-gapped computer from 4.0.

In this section, we need to “bridge the air gap.” This means that we will continue to perform the sensitive operations within the air-gapped computer, but we will use a networked smartphone’s QR code scanner to send the messages from the air-gapped computer to the Internet Computer.

Terminology

To “stake ICP” and to “create a neuron” are the same activity so they are used interchangeably.

Basic steps

Summary of steps

1. Send ICP to your ledger account number
2. Create a neuron
3. Set dissolve delay of neuron

Send ICP to your ledger account number

This account number lives in the Ledger canister that maintains the ICP addresses for the entire network. This account number is analogous to “addresses” in other blockchains. You need to send the ICP you want to stake to the ledger account number. In our case, the ledger account number from 4.1 was 77b5eb9a465f4ce6f4da494ee2bfedeefe0b52d106e0272556c1ad991f99e3da so that is the address we will use.

To create a neuron, you need to stake a minimum of 1 ICP. Anything less will not create a neuron.

If you cannot send ICP to your ledger account number, do not continue. Try again, check out support, or submit a question to support.
