opensea-js VS hardhat

We will create a web app that will let users mint a NFT in one click: creating an AI art from a prompt, storing it on IPFS and mint the unique NFT in Polygon so you can see it on OpenSea. Pretty cool right ?

It's peculiar considering it works fine for most games (R6S, GTAV, LoL, Valorant) but it's these odd situations that makes just light browsing a huge pain. An example I can think of where this is an issue is opensea.io where any animated sections cause my browser to lag until i navigate away from the content.

Some classic phishing attempts are fake e-mails from scammers pretending they are part of Opensea, Binance, Metamask, or individuals messaging you on Telegram, Discord, or Twitter pretending they are part of a team or interested to buy your assets in different means than through the trustable marketplaces.

Bulk Transfers and Collection Trading: The introduction of token-bound accounts enables the trading of entire NFT collections as a single unit. Platforms like OpenSea can leverage this functionality to facilitate bulk transfers of NFTs, streamlining collection management for both creators and collectors.

download metamask app, copy your secret recovery phrase and paste in metamask, then set up password, go to browser, type "opensea.io", then connect wallet, then profile!!

After manually flipping some bits, I'm pretty sure that the first part is meant to be https://opensea.io/

Smart contracts which deal with minting, listing, buying, selling, collecting, and viewing NFTs are called NFT smart contracts. NFTs are non-fungible tokens, which means these are some digital art, music, photographs, etc. which are up for sale digitally and are unique in the world. The biggest digital art (NFTs) market is Opensea. I will also be posting an article where I will create an NFT marketplace dApp from scratch soon.

Hardhat is an Ethereum development framework for creating, testing and deploying smart contracts. It includes a suite of tools that aid in developing smart contracts and managing the complete development process, allowing developers to write scripts, compile, test, and deploy efficiently.

That's it for the first part ! Then we will use Hardhat to deploy our Solidity Contract on the Polygon testnet, and then overload our mintNFT() function with the actual minting. If you want to see the Part 2 quickly, give us some love and we will execute ! ❤️❤️❤️

To keep things simple and visible (in case you cant deploy), we will use Sepolia testnet blockchain and Hardhat as development environment, so to configure hardhat to use sepolia we need to add the following configuration to the hardhat.config.js file:

The documentation has no mention of Trezor wallet support. According to this GitHub issue I could try out this Frame application, but I was wondering if there was a simpler solution that didn't require installing some 3rd party application.

I have two skipped tests because at the time of writing this article events firing doesn't work properly in the latest version. Link to the github issue

Hardhat

Other options include Remix (an IDE), ChainIDE, Anchor (for Solana), Hardhat, and lots of others. Web3 dev environments have come a long way in a short time, and there’s probably something out there for whatever you need.

Hardhat allows developers to build, test, and deploy smart contracts and dApps using a variety of tools and libraries. With over 114K users on GitHub and an active Discord community, Hardhat is a hugely popular framework for dApp developers. Much of its popularity can be attributed to its rich list of features, flexibility and the Hardhat Ethereum Virtual Machine for testing and debugging smart contracts.

The hardhat-ethers plugin adds the ethers.js library to the Hardhat node, making it possible to use its functionalities. It's possible to use it to deploy the contract, but since our goal is to create transactions, we can also add some code to do that as well.

Also learning how to use one of these development environments instead of Remix is necessary: 1. Hardhat: https://hardhat.org 2. Foundry: https://github.com/foundry-rs/foundry
