About Parity

Parity's goal is to be the fastest, lightest, and most secure Ethereum client. 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 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 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 1.6. 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 1.18.0 to build

We recommend installing Rust through rustup. If you don't already have rustup, you can install it like this:

• Linux:

   $ 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:

   $ 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:

sudo snap install parity --edge

(Note that this is an experimental and unstable release, at the moment)

---

Build from source

# 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:

$ ~/.cargo/bin/cargo build --release

---

Simple one-line installer for Mac and Ubuntu

bash <(curl https://get.parity.io -Lk)

Start Parity

Manually

To start Parity manually, just run

$ ./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".
