Summary

With this script, we send automated transactions in union bridge per 30 seconds

This script is specifically designed for stress testing one of the top zk-interoperability protocols, and it serves no other purpose

Make sure:

• You have enough ETH on Arbitrum Sepolia: Bridge
• You have enough BERA on berachain bArtio testnet: faucet
• You have enough UNO on berachain bArtio testnet & Arbitrum Sepolia: Bridge

Step 1- Create Hex

1- Transfer a small amount 0.000003257 (anything but low) of UNO from Arbitrum Sepolia and bArtio to Union

https://app.union.build/transfer

2- Copy and save the hex of the transactions of the both Arbitrum Sepolia and bArtio in the explorer

**Remember: You should have 2 hex strings in the final, 1 for Arbitrum + 1 for bArtio

Step 2- Run script

Install git & nodejs

sudo apt update && sudo apt upgrade -y
sudo apt install git screen

# Check Nodejs Version
node --version
# if 18, skip nodejs steps

# Delete Nodejs old files
sudo apt-get remove nodejs
sudo apt-get purge nodejs
sudo apt-get autoremove
sudo rm /etc/apt/keyrings/nodesource.gpg
sudo rm /etc/apt/sources.list.d/nodesource.list

# Install Nodejs 18
NODE_MAJOR=18
sudo apt-get update
sudo apt-get install -y ca-certificates curl gnupg
sudo mkdir -p /etc/apt/keyrings

curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg

echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_${NODE_MAJOR}.x nodistro main" | sudo tee /etc/apt/sources.list.d/nodesource.list

sudo apt-get update
sudo apt-get install -y nodejs
node --version

# Install npm
sudo apt-get install npm
npm --version

# Install yarn
curl -sSL https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt-get update -y
sudo apt-get install yarn -y

Config Script

npm install web3 readline-sync

git clone https://github.com/0xmoei/union-testnet
cd union-testnet

Run Script

# Start a screen
screen -S union

# Run
node union.js

Script asks you the network you want to transact on ,wallet privatekey ,and the hex you created in step 1

Check txs here

• to minimize screen= Ctrl+A+D
• to kill script= command: screen -XS union quit

I will add more routes and networks
