Fraxtal

Instructions to set up your frax node.

Requirements

Prerequisites

Terminal window
sudo apt-get install jq -y
snap install docker

Clone Repo

Terminal window
git clone https://github.com/FraxFinance/fraxtal-node.git
cd fraxtal-node

Set Environment Variables

Note: Update your shell profile in accordance with the shell you are using

Terminal window
DOCKER_COMPOSE_FILE_LOCATION=$HOME/fraxtal-node/docker-compose.yml >>
$HOME/.profile
Terminal window
DOCKER_COMPOSE_FILE_LOCATION=$HOME/fraxtal-node/testnet.docker-compose.yml
>> $HOME/.profile

Apply your changes

Terminal window
source $HOME/.profile

Set node config

Terminal window
cp .env.SAMPLE .env
Terminal window
cp .env.testnet.SAMPLE .env.testnet

Set the following config options in fraxtal-node/.env.testnet or fraxtal-node/.env:

Terminal window
# Your Ethereum RPC node endpoint. As an L2, your Frax node will verify tx finality by
# querying your own Ethereum RPC node.
OP_NODE_L1_ETH_RPC=

Start the node

Terminal window
docker compose -f $DOCKER_COMPOSE_FILE_LOCATION up -d

This should show an output like this:

Terminal window
[+] Running 3/3
mainnet-node 2 layers [⣿⣿] 0B/0B Pulled 3.0s
619be1103602 Pull complete 0.4s
b1167d0af7e0 Pull complete 1.7s
[+] Running 3/3
Network fraxtal-node_default Created 0.1s
Container fraxtal-node-mainnet-geth-1 Healthy 10.9s
Container fraxtal-node-mainnet-node-1 Started 11.2s

After it is done, verify by listing the services and their status

Terminal window
docker compose -f $DOCKER_COMPOSE_FILE_LOCATION ps

You should see these 2 services running

Terminal window
docker compose -f $DOCKER_COMPOSE_FILE_LOCATION logs $ENVIRONMENT-node --since 2m -f

You should see logs like

Verify node sync status

RPC Endpoint

Terminal window
echo "$(curl -4 ifconfig.co):8545"

Method:

Check your op node status at port 7545 by

Terminal window
curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"optimism_syncStatus","params":[],"id":1}' [rpc] | jq

If you get something like this in response to the above rpc call, your node is setup correctly

Terminal window
{
"jsonrpc": "2.0",
"id": 1,
"result": {
"current_l1": {
"hash": "0x24f7d66e8c80d0c6a598e9206ba1abc81264c1cc68afc14d8eca3f04fa81f921",

},
"sequenceNumber": 2
}
}
}

You can compare the block height on your node with explorer (mainnet or testnet), use your RPC node only when it has caught up with the latest block height.

Sync Status of Frax optimism Execution Node

You can check your status by connecting to geth console

Terminal window
docker exec -it fraxtal-node-$ENVIRONMENT-geth-1 geth attach http://localhost:8545
> eth.blockNumber
94078 # it will show you the latest block - number here is just an example
> eth.syncing
false

Configure vald

In order for vald to connect to your Fraxtal node, your rpc_addr should be exposed in vald’s config.toml

Terminal window
start-with-bridge = true
Terminal window
start-with-bridge = true
