🤔 What is this?

Lines is a decentralized message board.

  • It is a place where you can leave a message for others.

  • It is a place where you can read messages left by others.

  • It is a place where you can express yourself.

  • It is a place where you can be free.

Lines is a plain-text file stored on the Polygon blockchain. There are 2^256-1 lines on this wall. Each line is 100 characters long. The Wall will never be moderated. We believe that freedom of speech is one of the unalienable right for every man. Leave a message. It will be stored on-chain. Forever. Check out the website to try it yourself.

👛 Is it free?

Lines Board

Creation of new lines is free. Each modification of a line increases the cost for editing by 0.01 MATIC. If someone replaces your text you will receive 90% of what one has paid.

Line Tweets

Any time you like , create, repost, or follow an user, a small amount of MATIC is transferred to the post creator. The more followers you have, the more you earn.

If your content is reported by more than 10 users, your tweet will be deleted.

FOLLOW_PRICE = 0.0015;
LIKE_PRICE = 0.001;
RETWEET_PRICE = 0.0025;
REPORT_PRICE = 0.005;

You will find all your tweets at this address 🎉🎉🎉: https://linesapp.vercel.app/linetweets?id=<YOUR_ADDRESS_HERE>

  • nextjs - NextJS frontend for the Lines project

Quickstart 🚀

1. Clone this repo & install dependencies


git clone <https://github.com/Lines/lines-monorepo.git>
cd lines-monorepo
yarn install

2. Run a local network in the first terminal


yarn chain

3. On a second terminal, deploy the test contract


yarn deploy

4. On a third terminal, start your NextJS app


yarn start

Deploying Smart Contracts ⚒️

Once you are ready to deploy your smart contracts, there are a few things you need to adjust.

1: Select the network

By default, yarn deploy will deploy the contract to the local network. You can change the defaultNetwork in packages/hardhat/hardhat.config.js. You could also simply run yarn deploy --network target_network to deploy to another network.

Check the hardhat.config.js for the networks that are pre-configured. You can also add other network settings to the hardhat.config.js file. Here are the Alchemy docs for information on specific networks.

2: Generate a new account or add one to deploy the contract(s) from. Additionally you will need to add your Alchemy API key. Rename .env.example to .env and fill the required keys


ALCHEMY_API_KEY="",
DEPLOYER_PRIVATE_KEY=""

The deployer account is the account that will deploy your contracts and execute calls you make in your deployment script.

You can generate a random account / private key with yarn generate or add the private key of your crypto wallet. yarn generate will create a random account and add the DEPLOYER_PRIVATE_KEY to the .env file. You can check the generated account with yarn account.

3: Deploy your smart contract(s)

Run the command below to deploy the smart contract to the target network. Make sure to have some funds in your deployer account to pay for the transaction.


yarn deploy --network network_name

Deploying your NextJS App 📡

Run yarn vercel and follow the steps to deploy to Vercel. Once you log in (email, github, etc), the default options should work. It'll give you a public URL.

If you want to redeploy to the same production URL you can run yarn vercel --prod. If you omit the --prod flag it will deploy it to a preview/test URL.

Make sure your .env.production file has the values you need.

Hint: We recommend connecting the project GitHub repo to Vercel so you the gets automatically deployed when pushing to main
