Overview
Reth - short for Rust Ethereum, is an Ethereum full node implementation that is focused on being user-friendly, highly modular, as well as being fast and efficient.

1. Create service account and data directory
Create a service user for the execution service, create data directory and assign ownership.
Copy sudo adduser --system --no-create-home --group execution
sudo mkdir -p /var/lib/reth
sudo chown -R execution:execution /var/lib/reth
Install dependencies.
Copy sudo apt-get update
sudo apt install -y ccze jq curl
2. Install binaries
Downloading binaries is often faster and more convenient.
Building from source code can offer better compatibility and is more aligned with the spirit of FOSS (free open source software).
Option 1 - Download binaries
Copy RELEASE_URL = "https://api.github.com/repos/paradigmxyz/reth/releases/latest"
BINARIES_URL="$(curl -s $RELEASE_URL | jq -r '.assets[] | select(.name | startswith ("reth")) | .browser_download_url' | grep x86_64-unknown-linux-gnu.tar.gz$)"
echo Downloading URL: $BINARIES_URL
cd $HOME
wget -O reth.tar.gz $BINARIES_URL
tar -xzvf reth.tar.gz -C $HOME
rm reth.tar.gz
Install the binaries and display the version.
Copy sudo mv $HOME /reth /usr/local/bin
reth --version
Option 2 - Build from source codeInstall rust dependency
Copy curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
When prompted, enter '1' to proceed with the default install.
Update your environment variables.
Copy echo export PATH= "$HOME/.cargo/bin:$PATH" >> ~/.bashrc
source ~/.bashrc
Install rust dependencies.
Copy sudo apt-get update
sudo apt install -y git libclang-dev pkg-config build-essential
Build the binaries.
Copy mkdir -p ~/git
cd ~/git
git clone https://github.com/paradigmxyz/reth.git
cd reth
git fetch --tags
# Get latest tag name
latestTag = $( git describe --tags ` git rev-list --tags --max-count=1 ` )
# Checkout latest tag
git checkout $latestTag
# Build the release
cargo build --release --features jemalloc
In case of compilation errors, run the following sequence.
Copy rustup update
cargo clean
cargo build --release --features jemalloc
Verify Reth was built properly by checking the version number.
Copy ~ /git/reth/target/release/reth --version
Install the binary.
Copy sudo cp ~/git/reth/target/release/reth /usr/local/bin
3. Setup and configure systemd
Create a systemd unit file to define your execution.service
configuration.
Copy sudo nano /etc/systemd/system/execution.service
Paste the following configuration into the file.
Copy [Unit]
Description = Reth Execution Layer Client service for Holesky
Wants = network-online.target
After = network-online.target
Documentation = https://www.coincashew.com
[Service]

[Install]
WantedBy = multi-user.target
To exit and save, press Ctrl
+ X
, then Y
, then Enter
.
Run the following to enable auto-start at boot time.
Copy sudo systemctl daemon-reload
sudo systemctl enable execution
Finally, start your execution layer client and check it's status.
Copy sudo systemctl start execution
sudo systemctl status execution
Press Ctrl
+ C
to exit the status.
4. Helpful execution client commands
View Logs Stop Start View Status Reset Database
Copy sudo journalctl -fu execution | ccze
A properly functioning Reth execution client will indicate "Block added to canonical chain". For example,
Copy INFO reth::node::events: Forkchoice updated head_block_hash=2317ae..c41107 safe_block_hash=ab173f..33a21b finalized_block_hash=ab173f..33a21b status=Valid
INFO reth::node::events: Block added to canonical chain number=16000 hash=2317ae..c41107
INFO reth::node::events: Canonical chain committed number=16000 hash=2317ae..c41107 elapsed=12.508272ms
Copy sudo systemctl stop execution
Copy sudo systemctl start execution
Copy sudo systemctl status execution
Common reasons to reset the database can include:
Recovering from a corrupted database due to power outage or hardware failure
Re-syncing to reduce disk space usage
Upgrading to a new storage format
Copy sudo systemctl stop execution
sudo rm -rf /var/lib/reth/*
sudo systemctl restart execution
Time to re-sync the execution client can take a few hours up to a day.
Now that your execution client is configured and started, proceed to the next step on setting up your consensus client.
If you're checking the logs and see any warnings or errors, please be patient as these will normally resolve once both your execution and consensus clients are fully synced to the Ethereum network.
