Open-Transactions Library Project

License: MPL 2.0

Android Linux MacOS / Windows

The Open-Transactions project is a collaborative effort to develop a robust, commercial-grade, fully-featured, free-software toolkit implementing the OTX protocol as well as a full-strength financial cryptography library, API, CLI, and prototype server. The project is managed by a worldwide community of volunteers that use the Internet to communicate, plan, and develop the Open-Transactions toolkit and its related documentation.

About

Open-Transactions democratizes financial and monetary actions. You can use it for issuing currencies/stock, paying dividends, creating asset accounts, sending/receiving digital cash, writing/depositing cheques, cashier's cheques, creating basket currencies, trading on markets, scripting custom agreements, recurring payments, escrow, etc.

Open-Transactions uses strong crypto. The balances are unchangeable (even by a malicious server.) The receipts are destructible and redundant. The transactions are unforgeable. The cash is untraceable. The cheques are non-repudiable. Etc.

This product includes software developed by Ben Laurie for use in the Lucre project.

Configuration files for clang-format and cmake-format are available in otcommon.

Build Instructions

Ensure opentxs is fully checked out prior to running cmake:

git submodule update --init --recursive

Basic build instructions:

cmake --workflow --preset <preset_name>

See CMakePresets.json for a list of available presets.

With vcpkg

The environment variable VCPKG_ROOT must be set to an installation of vcpkg.

Additionally on Windows VCPKG_WINDOWS_MAX_PATH_HACK must be set to a directory with a short path name (e.g. C:\vcpkgbuild) to work around Windows platform limitations.

Without vcpkg

Install dependencies manually or with a system package manager.
