Moonbeam

Set up your Moonbeam (Moonbase-Alpha) Testnet node.

Prerequisites

Install required dependencies

In order to compile the moonbeam binary by yourself, you first need to setup the required dependencies. In this guide we will be using the release binary instead, so you can skip this step.

1. Setup Rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env
cargo build --release

Install Moonbase Alpha

In this guide we are using the release binary from PureStake. To get started, you need to download the latest version and create the systemd configuration file.

1. Download compiled binary
wget https://github.com/PureStake/moonbeam/releases/download/v0.17.0/moonbeam
2. Create service account and copy the binary
adduser moonbase_service --system --no-create-home
mkdir /var/lib/alphanet-data
cp ./moonbeam /var/lib/alphanet-data
sudo chown -R moonbase_service /var/lib/alphanet-data
3. Create the systemd service file

After installation of moonbase-alpha, we are now ready to start the node but in order to ensure it is running in the background and auto-restarts in case of a server failure, we will setup a service file using systemd.

📝

Note: In the service file below you need to replace "YOUR-NODE-NAME" and path to moonbeam, depending on your system configuration.

sudo tee <<EOF >/dev/null /etc/systemd/system/moonbeam.service

4. Enable and start the moonbeam service
sudo systemctl enable moonbeam.service
sudo systemctl start moonbeam.service

If everything was set-up correctly, your Moonbeam node should now be starting the process of synchronization. This will take several hours, depending on your hardware. In order to check the status of the running service or follow logs, you can use:

sudo systemctl status moonbeam.service
sudo journalctl -u moonbeam.service -f

Test your Moonbeam RPC connection

Once your Moonbeam node is fully synced, you can run a cURL request to see the status of your node:

curl -H "Content-Type: application/json" -d '{"id":1, "jsonrpc":"2.0", "method": "eth_syncing", "params":[]}' localhost:9933

If the node is successfully synced, the output from above will print {"jsonrpc":"2.0","result":false,"id":1}

EVM RPC endpoint URL

Axelar Network will be connecting to the EVM compatible Moonbean, so your rpc_addr should be exposed in this format:

http://IP:PORT

Example: http://192.168.192.168:9933
