We are developing Parity using the sophisticated and cutting-edge Rust programming language. Parity is licensed under the GPLv3, and can be used for all your Ethereum needs. Parity comes with a built-in wallet. To access [Parity Wallet](http://web3.site/) simply go to http://web3.site/ (if you don't have access to the internet, but still want to use the service, you can also use http://127.0.0.1:8180/). It includes various functionality allowing you to: - create and manage your Ethereum accounts; - manage your Ether and any Ethereum tokens; - create and register your own tokens; - and much more. By default, Parity will also run a JSONRPC server on `127.0.0.1:8545`. This is fully configurable and supports a number of RPC APIs. If you run into an issue while using parity, feel free to file one in this repository or hop on our [gitter chat room](https://gitter.im/paritytech/parity) to ask a question. We are glad to help! **For security-critical issues**, please refer to the security policy outlined in `SECURITY.MD`. Parity's current release is 1.7. You can download it at https://github.com/paritytech/parity/releases or follow the instructions below to build from source. ---- ## Build dependencies **Parity requires Rust version 1.19.0 to build** We recommend installing Rust through [rustup](https://www.rustup.rs/). If you don't already have rustup, you can install it like this: - Linux: ```bash $ curl https://sh.rustup.rs -sSf | sh ``` Parity also requires `gcc`, `g++`, `libssl-dev`/`openssl`, `libudev-dev` and `pkg-config` packages to be installed. - OSX: ```bash $ curl https://sh.rustup.rs -sSf | sh ``` `clang` is required. It comes with Xcode command line tools or can be installed with homebrew. - Windows Make sure you have Visual Studio 2015 with C++ support installed. Next, download and run the rustup installer from https://static.rust-lang.org/rustup/dist/x86_64-pc-windows-msvc/rustup-init.exe, start "VS2015 x64 Native Tools Command Prompt", and use the following command to install and set up the msvc toolchain: ``` $ rustup default stable-x86_64-pc-windows-msvc ``` Once you have rustup, install parity or download and build from source ---- ## Install from the snap store In any of the [supported Linux distros](https://snapcraft.io/docs/core/install): ```bash sudo snap install parity --edge ``` (Note that this is an experimental and unstable release, at the moment) ---- ## Build from source ```bash # download Parity code $ git clone https://github.com/paritytech/parity $ cd parity # build in release mode $ cargo build --release ``` This will produce an executable in the `./target/release` subdirectory. Note: if cargo fails to parse manifest try: ```bash $ ~/.cargo/bin/cargo build --release ``` ---- ## Simple one-line installer for Mac and Ubuntu ```bash bash <(curl https://get.parity.io -Lk) ``` ## Start Parity ### Manually To start Parity manually, just run ```bash $ ./target/release/parity ``` and Parity will begin syncing the Ethereum blockchain. ### Using systemd service file To start Parity as a regular user using systemd init: 1. Copy `parity/scripts/parity.service` to your systemd user directory (usually `~/.config/systemd/user`). 2. To pass any argument to Parity, write a `~/.parity/parity.conf` file this way: `ARGS="ARG1 ARG2 ARG3"`. Example: `ARGS="ui --identity MyMachine"`.
