polymer-dev-testnet

Follow my steps, copy and paste the codes one by one

Start here

sudo apt update -y && sudo apt upgrade -y
sudo apt-get install git -y
sudo apt-get install -y ca-certificates curl gnupg
sudo mkdir -p /etc/apt/keyrings

continue in here

sudo nano /etc/apt/sources.list.d/nodesource.list

We are in the file, now paste this and then CTRL+X + Y then Enter ( save and exit )

# deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_ jammy main

continue on the main screen

sudo apt update -y && sudo apt upgrade -y
sudo apt-get install -y nodejs

polymer set up

git clone https://github.com/sarox0987/polymerlab-ibc-app-solidity.git
cd polymerlab-ibc-app-solidity

just and forge's set up

curl --proto '=https' --tlsv1.2 -sSf https://just.systems/install.sh | bash -s -- --to /usr/local/bin
curl -L https://foundry.paradigm.xyz | bash
source /root/.bashrc
foundryup
forge build

Required steps

1-Create new testnet wallet in Metamask and copy it's key 2- Create Alchemy account 3- Create Optimism Sepolia and Base Sepolia App ( copy their's key only - not RPC keys- first key ) 4- Get faucet for both Op - Sepolia Faucet Base - Sepolia Faucet

enter env file

nano .env

Fill this parts :

PRIVATE_KEY_1 = Metamask private key

OP_ALCHEMY_API_KEY = Optimism API Key

BASE_ALCHEMY_API_KEY = BaseAPI Key

CTRL+X +Y and Enter

create channels

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
source ~/.bashrc
nvm install 18
nvm use 18
npm install
just install
just do-it

use this code if you couldnt install just and got error, otherwise skip this step

wget -qO - 'https://proget.makedeb.org/debian-feeds/prebuilt-mpr.pub' | gpg --dearmor | sudo tee /usr/share/keyrings/prebuilt-mpr-archive-keyring.gpg 1> /dev/null
echo "deb [arch=all,$(dpkg --print-architecture) signed-by=/usr/share/keyrings/prebuilt-mpr-archive-keyring.gpg] https://proget.makedeb.org prebuilt-mpr $(lsb_release -cs)" | sudo tee /etc/apt/sources.list.d/prebuilt-mpr.list
sudo apt update

You should be good after running just do-it code. Codes will run and it will say " You are done" at the end. Take ss and send it to their discord.

send your proof to this channel : Proof

If you get error :

First of all make sure you have eth both sepolia chains. If you have testnet tokens then use this codes

npx hardhat clean
just do-it 

till you see you are done.
