## About
Pallectrum is a lightweight Palladium wallet based on [Electrum](https://electrum.org/), 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](README-ELECTRUM.md).
**Credits**: Pallectrum is based on [Electrum](https://github.com/spesmilo/electrum) by Thomas Voegtlin and contributors. We are grateful for their excellent work.
