Wait for a formal release before use with real funds. A trust-minimized Bitcoin wallet interface that relies only on Bitcoin Core. - Zero install process for most platforms - Designed for simplicity and auditability - No GUI, terminal only (curses and command-line) - Works in terms of script descriptors and PSBTs - Minimal dependencies: Bitcoin Core, Python 3 interpreter, nothing else - Supports only airgapped, opensource hardware wallets - Integrates with GPG and pass for secure xpub storage In short, this is the easiest way to do air-gapped wallet management with Bitcoin Core, Coldcard, and not much else. --- - Design - Status - Usage - Security assumptions - Configuration - FAQ - Why is there no GUI? - Why do you only support Coldcard? Will you add others? - Why did you use Python and not {Rust,Haskell,C++}? - Why do you encrypt the config file by default with GPG? - Donate - TODO/Roadmap --- Requirements - Linux or MacOS - Support for Windows is planned, but I'll need someone with a Windows computer to help - Bitcoin Core 0.19+ - Python 3.7+ (your system probably already has this) - Coldcard (original or Q) macOS newbie-friendly install process Not super familiar with the commandline? On macOS? Check out the easy setup tutorial here. Install process 1. Buy a Coldcard 1. Download, install, and sync Bitcoin Core - If possible, sync with -blockfilterindex=1 for much faster wallet scanning.
