# Validator Quickstart

Our `raiku-agave` client is built on top of `jito-agave`.<br>

If you're already running Jito, switching to Raiku means adding just a few flags to your existing validator startup. **Jito Classic and Raiku coexist.** This means no changes to your pre-existing Jito configuration are required.

{% hint style="warning" %}
Raiku is **not** compatible with Jito BAM.
{% endhint %}

\
The Raiku validator is available at [raiku-agave](https://github.com/raiku-protocol/raiku-agave) to our pilot program partners and will be open-sourced at the end of the pilot program.&#x20;

{% hint style="info" %}
The Raiku client shares the same hardware requirements as the Agave validator client, which can be found [here](https://docs.anza.xyz/operations/requirements).
{% endhint %}

## Already running jito-agave?

Follow the install process and add the following flags to your existing validator startup command:

```bash
--raiku-engine-url https://engine.testnet.raiku.sh:443 \
--raiku-merkle-root-upload-authority 7maV3ghmAJZGmzCBa8xNWVkrz4S1WHiCXzAZhPufBY8e \
--raiku-commission-bps 500
```

That's it. Your existing Jito flags stay unchanged.

## Building from Source

### 1. Install rustc, cargo & rustfmt

```bash
curl https://sh.rustup.rs -sSf | sh
source $HOME/.cargo/env
rustup component add rustfmt
```

When building the master branch, make sure you are using the latest stable Rust version:

```bash
rustup update
```

When building a specific release branch, check the Rust version in `ci/rust-version.sh` and install it if needed:

```bash
rustup install VERSION
```

> **Note:** If this is not the latest Rust version on your machine, cargo commands may require an [override](https://rust-lang.github.io/rustup/overrides.html) in order to use the correct version.

On Linux systems you may need to install `libssl-dev`, `pkg-config`, `zlib1g-dev`, `protobuf` etc.

#### On Ubuntu

```bash
sudo apt-get update
sudo apt-get install libssl-dev libudev-dev pkg-config zlib1g-dev llvm clang cmake make libprotobuf-dev protobuf-compiler
```

#### On Fedora

```bash
sudo dnf install openssl-devel systemd-devel pkg-config zlib-devel llvm clang cmake make protobuf-devel protobuf-compiler perl-core
```

### 2. Download the Source Code

```bash
export CARGO_NET_GIT_FETCH_WITH_CLI=true
git clone https://github.com/raiku-protocol/raiku-agave.git
cd raiku-agave
git submodule update --init --recursive
```

### 3. Build the Client

```bash
cargo build --release
```
