This app adds support for the Solana native token to Ledger Nano S hardware wallet.

Current Features:

• Pubkey queries
• Parse, display and sign all Solana CLI generated transaction formats
• Blind sign arbitrary transactions (Enabled via settings)

• Install Docker
• For Linux hosts, install the Ledger Nano udev rules

Ubuntu Linux:

sudo apt install pip3

MacOS

brew install python3

pip3 install ledgerblue

• Setup environment

cat >>"${HOME}"/.profile <<EOF
LEDGER_SDK_BASE_PATH= # set to a writable path
: "${LEDGER_SDK_BASE_PATH:?}"
export NANOS_SDK="${LEDGER_SDK_BASE_PATH}"/nanos-secure-sdk
export NANOX_SDK="${LEDGER_SDK_BASE_PATH}"/nanox-secure-sdk
export NANOSP_SDK="${LEDGER_SDK_BASE_PATH}"/nanosplus-secure-sdk
EOF

• Update the current session's environment

. "${HOME}"/.profile # Or close and reopen your terminal

• Clone the repositories

# Nano S SDK
git clone --branch 2.1.0 --depth 1 https://github.com/LedgerHQ/nanos-secure-sdk.git "${NANOS_SDK}"

# Nano X SDK
git clone --branch 2.0.2-2 --depth 1 https://github.com/LedgerHQ/nanox-secure-sdk.git "${NANOX_SDK}"

It is highly recommended that you read and understand the Ledger App Builder build process before proceeding. A convenience wrapper script (./docker-make) has been provided for simplicity

docker-make manages the current target SDK for you, automatically setting BOLOS_SDK to the correct path when the Docker container is launched. A TARGET_SDK must be specified when building from clean and clean must be run before switching

./docker-make <TARGET_SDK>

./docker-make clean

Requires that the BOLOS_SDK envvar be set. This can be achieved by first building for the desired target device.

make load-only

make delete

Run C tests:

make -C libsol

First enable blind-signing in the App settings

cargo run --manifest-path tests/Cargo.toml
