Welcome to the world of Matic Network’s Proof-of-Stake portal contracts! Deploying these smart contracts can seem daunting at first, but with this guide, you’ll navigate through the setup process with ease. Follow along as we outline the steps necessary to get your Matic PoS portal contracts up and running!

1. Prerequisites

Before you dive in, make sure you have the following tools installed:

• NodeJS
• NPM

Check your installations with these commands:

node --version
npm --version

2. Install the Matic PoS Portal Package

First, you’ll need to install the package from NPM. Just type the following command in your terminal:

npm i @maticnetworkpos-portal

3. Clone the Repository

Once the package is installed, you can clone the repository and install all dependencies:

git clone https://github.com/maticnetwork/pos-portal
cd pos-portal
npm i

4. Compile All Contracts

Now we’ll compile the contracts:

npm run template:process
npm run build

5. Setting Up Multichain Environment

To deploy your contracts successfully, you will need at least two chains running – the RootChain (Ethereum) and the ChildChain (Polygon). You can set this up in two ways:

• With matic-cli
• Without matic-cli

5.1. Setting Up With matic-cli

If you’ve installed matic-cli, follow the guide on its README to set up a single node local network. Ensure you start all components separately and update the necessary RPC addresses in truffle-config.js based on the Ganache and Bor setups you have running. Update important contract addresses accordingly.

5.2. Setting Up Without matic-cli

If you prefer doing it manually, you can run a Ganache instance for the RootChain and a Bor instance for the ChildChain using the following commands:

npm run testrpc
npm run bor

6. Running Migrations

To complete the deployment, execute the migration script:

npm run migrate

This will deploy all necessary contracts and save their addresses for future interactions.

Troubleshooting Tips

If you run into issues during deployment, consider the following:

• Check the truffle-config.js for incorrect RPC addresses.
• Inspect the migrations/1,2,3,4,5*.js files for proper contract migration scripts.
• Ensure that you’ve installed all dependencies correctly before migrating.
