Secure Bitcoin wallet with Vault multi-sig, Liquid spending, Buy/Sell and inheritance.
COINCUBE is a comprehensive Bitcoin wallet solution built on a hard fork of Liana with significant modifications by Coincube Technology LLC. We retain the original license and acknowledge the foundational work of the Liana project. This wallet provides:
VAULT - Secure multisig custody with time-locked inheritance paths. Like the original Liana, you have a primary spending path (always accessible) and recovery paths (available after inactivity periods). You may have multiple keys in either path. Recovery paths are enforced onchain by Bitcoin's Script capabilities.
Example VAULT configuration:
- Owner's key (can always spend)
- Any 2 keys from trusted parties (after 1 year)
- Emergency recovery key (after 1 year and 3 months)
LIQUID WALLET - Lightning-enabled spending wallet powered by Breez SDK for instant, low-fee payments. Liquid is a sidechain of Bitcoin that provides low cost payments and confidential transactions.
BUY/SELL - Integrated Bitcoin on/off-ramp functionality.
COINCUBE is designed for trustless inheritance, loss protection, liquid spending, and user-friendly Bitcoin custody.
COINCUBE is available on Windows, Mac and Linux. To install and start using it see
doc/USAGE.md.
If you just want to quickly try out COINCUBE on Bitcoin Signet or Testnet, see doc/TRY.md.
COINCUBE is an open source project. It is hosted at Github. Contributions are welcome. See here for guidelines.
COINCUBE is separated in main components:
The daemon contains the core Vault logic. It is both a library (Rust crate) that exposes a command interface and a standalone daemon that exposes a JSONRPC API through a Unix Domain Socket.
The code for the daemon can be found in the coincubed folder (to be renamed to coincubed).
The GUI provides an installer for setting up COINCUBE and a graphical interface
built with the iced library.
The code for the GUI can be found in the coincube-gui folder.
Lightning-enabled spending wallet integration with Breez SDK (under development).
