Set up your Fantom Mainnet or Testnet Opera node.


Install required dependencies

In order to build the go-opera, you first need to install all of the required dependencies.

1. Update and install build-essential

sudo apt-get update
sudo apt-get -y upgrade
sudo apt-get install -y build-essential

2. Install golang

Install the latest version of golang.

Install Go-Opera

1. Checkout and build go-opera

Please make sure you checkout the latest release tag.

git clone
cd go-opera/
git checkout release/[latest version]

2. Download the genesis file

cd build/

# wget

3. Create systemd service file

After installation of go-opera, we are now ready to start the process 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 with systemd.


Note: In the service file below you need to replace $USER and path to opera, depending on your system configuration.

sudo tee <<EOF >/dev/null /etc/systemd/system/fantom.service
Description=Fantom Node

ExecStart=/root/go-opera/build/opera --genesis /root/go-opera/build/mainnet-109331-pruned-mpt.g --identity <your_name> --cache 8096 --http --http.addr --http.corsdomain '*' --http.vhosts "*" --http.api "eth,net,web3" 


If you would like to run a node on the Testnet instead, you need to replace --genesis /root/go-opera/build/testnet-6226-pruned-mpt.g in the configuration above.

4. Enable and start the fantom service

sudo systemctl enable fantom
sudo systemctl daemon-reload
sudo systemctl start fantom

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

sudo systemctl status fantom
sudo journalctl -u fantom -f

Your node will now start to synchronize with the network. It will take several hours before the node is fully synced.

Test your Fantom RPC connection

Once your 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:18545

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

EVM RPC endpoint URL

In order for Axelar Network to connect to your Fantom node, your rpc_addr should be exposed in this format:
