Building

Prerequisites

• CMake 3.16+
• C++20 compiler
• Qt 6.x (Widgets, Charts, Network, Sql, Concurrent, Svg)
• libsodium
• libqrencode

macOS

brew install qt@6 libsodium qrencode hidapi libusb

mkdir build && cd build
cmake ..
cmake --build .

# Run
open Cinder.app

Linux (Ubuntu/Debian)

sudo apt install qt6-base-dev qt6-charts-dev libsodium-dev libqrencode-dev \
                 libhidapi-dev libusb-1.0-0-dev cmake build-essential

mkdir build && cd build
cmake ..
cmake --build .

./Cinder

Windows

1. Install Qt 6, CMake, and Visual Studio 2019+
2. Install vcpkg dependencies: libsodium, qrencode, hidapi, libusb

mkdir build && cd build
cmake -DCMAKE_PREFIX_PATH="C:/Qt/6.x/msvc2019_64" ..
cmake --build . --config Release

Development rebuild

# Kills any running instance, rebuilds the app target only, and launches
bash build-and-run.sh

# If you intentionally want to rebuild tests and other targets too
bash build-and-run.sh --all-targets

Security

• Non-custodial — private keys never leave your machine
• Encrypted storage — Argon2id key derivation, XSalsa20-Poly1305 authenticated encryption
• Hardware wallet signing — transactions signed on-device
• Biometric unlock — macOS Touch ID with Keychain integration
