Setting Up Gear Node


This guide covers the steps required to install and run the Gear node.

There are two ways to get started with the Gear node. First, you can download a pre-built binary file and run it, or second, you can compile the binary file and configure it by yourself. Using a ready-made build is a quick and convenient way to get started as you can skip the installation of Rust and all its dependencies and you can also skip the node compiling process. On the other hand, if you decide that you want to go through the process of creating your development node, it may take about twenty minutes or more depending on your hardware.


System requirements:​

Gear node doesn't have any special hardware requirements excepting at least 64 Gbytes of free space on the SSD disk.

Install with pre-build binary​

Depending on your OS you need to download nightly build of Gear node:


curl -O


Windows x64:

Unzip the downloaded package then you can try to run the node:

❯ gear.exe --version
gear.exe 0.1.0-hashcode

Compile Gear node by yourself​

Compiling the build will take some time and requires the installation of some dependencies.


Windows users may encounter some problems related to the installation of Rust components and dependencies. It is highly recommended to use Linux or macOS for compiling Gear node and smart-contracts.


Linux users should generally install GCC and Clang, according to their distribution’s documentation. Also, one should install binaryen toolset that contains required wasm-opt tool.

For example, on Ubuntu use:

sudo apt install -y clang build-essential binaryen cmake protobuf-compiler

On macOS, you can get a compiler toolset and binaryen by running:

xcode-select --install
brew install binaryen

Install Rust:​

If you already have Rust installed, you can skip this step.

curl --proto '=https' --tlsv1.2 -sSf | sh

And then you should reboot your terminal.

Install Wasm Toolchains:​

rustup toolchain add nightly
rustup target add wasm32-unknown-unknown --toolchain nightly

Clone Gear repo​

git clone
cd gear
git checkout testnet

## Optional
## If you need to use the latest or experimental Gear functions,
## you should compile `gear-node` from `master` branch.


cargo build -p gear-cli --release


make node-release

You can find the final build at the following location: gear/target/release/gear

Go to:

cd target/release

Run Gear Node​


It doesn't matter if you downloaded the prebuild binary or built it yourself. Being in the directory where the gear node is installed to run it without special arguments to get a node connected to the testnet:


To run Gear node in dev mode use the following command:

./gear --dev

Command Flags and Options​

gear [subcommand] [options]
  • --chain=staging

    Connect the node to Gear testnet (default option).

  • --dev

    Run standalone node of Gear network.

  • purge-chain

    Remove storage of the selected chain type. Needs to specify the chain connection type --chain=staging or --dev

  • help, --help

    Print the available subcommands/options or the help of the given subcommand.

Special environment variables​

To run Gear node with logs from contracts use:

RUST_LOG="gwasm=debug" gear [subcommand] [options]
