Building a NFT Marketplace on Ethereum with Polygon and Next.js

How to start NFT Marketplace Development?

In this video, you'll learn how to build a full stack NFT marketplace on Ethereum with Solidity, Polygon, IPFS, Next.js, Ethers.js, and Hardhat.

We'll start from scratch, creating a new project and installing the dependencies. We'll then write and test out the smart contracts. Once the tests have passed, we'll write the front end code to connect the smart contracts.

After testing on a local network, we'll deploy to the Matic / Polygon network using a custom RPC provider (Infura).

POLYGON (MATIC) WILL POLYGON SHAKE UP THE TOP TWO (BITCOIN / ETH)?

Polygon (formerly Matic Network) is a Layer 2 scaling solution backed by Binance and Coinbase. The project seeks to stimulate mass adoption of cryptocurrencies by resolving the problems of scalability on many blockchains.

Polygon combines the Plasma Framework and the proof-of-stake blockchain architecture. The Plasma framework used by Polygon as proposed by the co-founder of Ethereum, Vitalik Buterin, allows for the easy execution of scalable and autonomous smart contracts.

Nothing will change for the existing ecosystem built on the Plasma-POS chain. With Polygon, new features are being built around the existing proven technology to expand the ability to cater to diverse needs from the developer ecosystem. Polygon will continue to develop the core technology so that it can scale to a larger ecosystem.

Polygon boasts of up to 65,000 transactions per second on a single side chain, along with a respectable block confirmation time of less than two seconds. The framework also allows for the creation of globally available decentralized financial applications on a single foundational blockchain.

The Plasma framework gives Polygon the potential of housing an unlimited number of decentralized applications on their infrastructure without experiencing the normal drawbacks common on proof-of-work blockchains. So far, Polygon has attracted more than 50 DApps to its PoS-secured Ethereum sidechain.

MATIC, the native tokens of Polygon, is an ERC-20 token running on the Ethereum blockchain. The tokens are used for payment services on Polygon and as a settlement currency between users who operate within the Polygon ecosystem. The transaction fees on Polygon sidechains are also paid in MATIC tokens.

Git3 – First Alpha Release

In October 2020 I participated in the EthOnline hackathon in which I worked on a decentralized Github version. During the hackathon I created a simple PoC, showing that a Git repository can be represented by a Smart Contract and that the files/objects can be stored on IPFS. I received messages from people showing interest in my project. Therefore, I decided to continue working on this project.

So, what’s the current stage? I was able to release the very first alpha version, yay. It took me some time to get here since the Smart Contracts had to be rewritten, deployed on Polygon, and the git3 client had to be fixed. But, with this article I want to give you a step-by-step guide on how to use the Git3 Client, create a repository, and how to push content.

Keep in mind that it is an alpha stage and contains bugs! The Smart Contracts are deployed on the Polygon Testnet, so test as much as you want.

I tested the code on macOS Big Sur Version 11.2.3 using Python3.8 within the terminal. If you test it on a different OS, let me know, since I have not had the chance to test it on a different OS.

Without further ado, let’s get to it

Installing Git3 Client

The Git3 client is written in Python3 and you can install it using pip. To install the git3 client, run the following command in your terminal:

pip install git3Client==0.1.2

You should be able to run git3 in your terminal and receive a small message that command is required.
