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: Download pallectrum-x.x.x-x86_64.AppImage
• Android: Download pallectrum-x.x.x.apk
