Fraxtal

Instructions to set up your frax node.

Requirements

Setup your Axelar validator
Minimum hardware requirements: 8 AWS vCPU+, 8GB RAM, 512GB of SSD free storage space.
MacOS or Ubuntu 22.04 (tested on 22.04)
Official Documentation
Official Documentation

Prerequisites

Common Docker Compose Commands

sudo apt-get install jq -y
snap install docker

Clone Repo

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

echo export ENVIRONMENT=mainnet >> $HOME/.profile
echo export DOCKER_COMPOSE_FILE_LOCATION=$HOME/fraxtal-node/docker-compose.yml >> $HOME/.profile

echo export ENVIRONMENT=testnet >> $HOME/.profile
echo export DOCKER_COMPOSE_FILE_LOCATION=$HOME/fraxtal-node/testnet.docker-compose.yml >> $HOME/.profile

Apply your changes

source $HOME/.profile

Set node config

cp .env.SAMPLE .env

cp .env.testnet.SAMPLE .env.testnet

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

# 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

docker compose -f $DOCKER_COMPOSE_FILE_LOCATION up -d

This should show an output like this:

RPC Endpoint

echo "$(curl -4 ifconfig.co):7545"

Method:

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

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

        "number": 323353
      },
      "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

docker exec -it fraxtal-node-$ENVIRONMENT-geth-1 geth attach http://localhost:8545
> eth.blockNumber
35065 # 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

[[axelar_bridge_evm]]
name = "fraxtal"
rpc_addr = "http://IP:PORT"
start-with-bridge = true

[[axelar_bridge_evm]]
name = "fraxtal"
rpc_addr = "http://IP:PORT"
start-with-bridge = true
