Hedera™ C++ SDK

The SDK for interacting with Hedera Hashgraph: the official distributed consensus platform built using the hashgraph consensus algorithm for fast, fair and secure transactions. Hedera enables and empowers developers to build an entirely new class of decentralized applications.

SDK IS NOT READY FOR PRODUCTION USE. IT IS CURRENTLY STILL UNDER DEVELOPMENT.

git submodule update --init

# Windows (x64) Build
cmake --preset windows-x64-release
cmake --build --preset windows-x64-release

# Linux (x64) Build
cmake --preset linux-x64-release
cmake --build --preset linux-x64-release

# MacOS (Intel x64) Build
cmake --preset macos-x64-release
cmake --build --preset macos-x64-release

# MacOS (Aarch64) Build
cmake --preset macos-arm64-release
cmake --build --preset macos-arm64-release
