Pallectrum - Lightweight Palladium Wallet

Licence: MIT Licence
Version: 1.0.1
Maintainer: Davide Grilli
Language: Python (>= 3.10)

About

Pallectrum is a lightweight Palladium wallet based on Electrum, the popular Bitcoin wallet. It offers the same ease of use, security features, and extensibility that Electrum is known for, but adapted for the Palladium blockchain.

Key Features

• Instant on: Your wallet is ready to use immediately - no blockchain download required
• Secure: Your private keys are encrypted and never leave your computer
• Forgiving: Your funds can be recovered from a secret seed phrase
• Cold Storage: Keep your private keys offline and transact using a watching-only wallet
• Multi-signature support: Split the permission to spend your coins between several wallets
• Hardware wallet support: Compatible with popular hardware wallets (Trezor, Ledger, etc.)
• Lightning Network: Fast and low-cost payments (experimental)

Based on Electrum

Pallectrum is a fork of Electrum v4.6.2, adapted to work with the Palladium blockchain. For the original Electrum documentation, see README-ELECTRUM.md.

Credits: Pallectrum is based on Electrum by Thomas Voegtlin and contributors. We are grateful for their excellent work.

Getting Started

Installation

The easiest way to run Pallectrum is to download the pre-built binaries:

• Windows: Two versions available:
  • pallectrum-x.x.x-portable.exe - Recommended for USB drives. Saves all data (wallets, configuration) in the same directory as the executable. Perfect for portable installations.
  • pallectrum-x.x.x-setup.exe - Standalone installer. Installs to Program Files and saves data in %APPDATA%\Pallectrum.
• Linux: Two versions available:
  • pallectrum-x.x.x-x86_64.AppImage - For Intel/AMD 64-bit systems
  • pallectrum-x.x.x-aarch64.AppImage - For ARM64 systems
• Android: Download pallectrum-x.x.x.apk

Running from Source

Running from source requires Python 3.10 or higher. Follow the steps for your platform below.

---

Windows

Prerequisite: Python 3.10+ from python.org

# Clone the repository
git clone https://github.com/palladium-coin/pallectrum.git
cd pallectrum

# Create and activate a virtual environment
python -m venv env
env\Scripts\Activate.ps1

# Install dependencies
python -m pip install --upgrade pip
pip install -e ".[gui,crypto]"

# Copy the secp256k1 library (required on Windows)
copy libsecp256k1*.dll env\Lib\site-packages\electrum_ecc\

# Launch
python run_electrum

Optional – QML GUI (simulates the Android interface):

pip install -e ".[qml_gui]"
python run_electrum -g qml

---

Linux (Ubuntu / Debian)

1. Install system prerequisites

sudo apt update
sudo apt install -y \
  python3-venv python3-pip python3-dev build-essential \
  libffi-dev libssl-dev libsecp256k1-dev libpulse0

2. Clone the repository and set up the virtual environment

git clone https://github.com/palladium-coin/pallectrum.git
cd pallectrum

python3 -m venv env
source env/bin/activate
python3 -m pip install --upgrade pip

3. Install dependencies

3.1. x86_64 (Intel / AMD)

pip install -e ".[gui,crypto]"

3.2. ARM64 / aarch64

PyQt6 ≥ 6.9 wheels are not published for ARM64 on PyPI — pinned versions must be used.

pip install -r contrib/requirements/requirements.txt
pip install "cryptography>=2.6"
pip install --only-binary PyQt6,PyQt6-Qt6,PyQt6-sip \
  "PyQt6>=6.7.0,<6.8.0" \
  "PyQt6-Qt6>=6.7.0,<6.8.0" \
  "PyQt6-sip==13.10.2"
pip install -e .

4. Launch

python run_electrum

4.1. Optional – QML GUI (Android-like interface)

x86_64

pip install -e ".[qml_gui]"
python run_electrum -g qml

ARM64 — the pinned PyQt6 packages installed in step 3 already include QML support:

python run_electrum -g qml
