Using Ledger on a remote machine

This is a step-by-step guide on how to use Ledger on a remote machine

Lotus users might want to use a Ledger device for the owner-address of an SPs for higher security. Often This tutorial is based on a setup with two different servers, one to run the lotus daemon while the other runs the lotus-wallet application.

Prerequisites #

• A lotus daemon running and being in-sync on a separate server, hereafter called lotus-node operator.
• A machine where you plan to plug in and use the Ledger device, hereafter called ledger-provider.

As the “Ledger-provider” (Linux specific) #

1. Install lotus-shed and lotus-wallet (Linux specific):

sudo apt install

As the “Ledger-provider” (Mac specific) #

1. Install lotus-shed and lotus-wallet (Mac specific):

Install the required depencies with:

brew install go jq pkg-config hwloc

Clone the Lotus-repo with:

git clone https://github.com/filecoin-project/lotus

Change directory to Lotus with:

cd lotus

Install lotus-shed and lotus-wallet

make lotus-shed lotus-wallet

As the “lotus-node operator” #

1. On your node that is in sync with the chain, setup a remote wallet backend:

In your .lotus/config.toml file:

[Wallet]
  RemoteBackend = "http://127.0.0.1:1777"

2. Import the wallet:

lotus wallet import --format json-lotus

And paste the JSON-line that was given to you in the third step in the As the "Ledger-provider" section.

3. That is it! 🚀

As long as the ssh reverse-tunnel is alive, you will be required to confirm transactions on the Ledger whenever the Lotus node makes them.
