Prerequisites

Git
Python 3 - Python3.11 Recommended
Systemd (usually pre-installed on most Linux distributions)
Sudo privileges
Server running symphonyd with synced status

Install Dependencies

sudo apt -q update
sudo apt -qy install curl git jq lz4 build-essential
sudo apt -qy upgrade
sudo apt-get update && apt-get install -y libssl-dev

Navigate to the project directory and checkout current version

cd symphony-oracle-voter
git checkout v0.0.4r3

Create a .env file

Use the below format for .env identity

VALIDATOR_ADDRESS= symphonyvaloperxxx
VALIDATOR_ACC_ADDRESS = symphonyxxx
KEY_PASSWORD= keyringpassword
SYMPHONY_LCD = https://api.symphony.ravenode.xyz/
TENDERMINT_RPC = https://rpc.symphony.ravenode.xyz/

Adjust VALIDATOR_ADDRESS, VALIDATOR_ACC_ADDRESS, and KEY_PASSWORD with your own validator details.

Create python virtual environment

python3 -m venv venv
