Note: This guide only works on ledger nanos, and your device must have sufficient space to install the app

OS: LINUX

pre-requisites:

• Install docker from here : Docker

• add and reload the udev rules to allow USB access to your Ledger device:

wget -q -O - https://raw.githubusercontent.com/LedgerHQ/udev-rules/master/add_udev_rules.sh | sudo bash

• Edit Makefile, find COIN=bitcoin_legacy and replace it to COIN=blocx, this line will use to select the app which you want to upload in your ledger nanos.

Download Blocx-ledger

git clone https://github.com/BLOCXTECH/app-bitcoin.git

• Move into that repo

cd app-bitcoin

Run below command

• It will take some time depending on your network

sudo docker run --rm -ti --user "$(id -u):$(id -g)" --privileged -v "/dev/bus/usb:/dev/bus/usb" -v "$(realpath .):/app" ghcr.io/ledgerhq/ledger-app-builder/ledger-app-dev-tools:latest

• After running above command you will get new terminal, it will look something like : bash-5.1$

• Run below command in this terminal

BOLOS_SDK=$NANOS_SDK

make DEBUG=1

• Now, below command will load blocx application to your ledger nanos

make load

Note: During make load command, there will be some conformations in ledger.
