nft.storage VS hardhat

That flagship app you are looking for seems to be https://nft.storage/ (by Protocol Labs).

And make free uploads to it here: https://nft.storage

Diagram Roughly like this. I use https://nft.storage/ for all my nft projects

NFT.Storage is a counterpart to Web3.Storage for a specific purpose: a place to safely store and save your NFTs. Many people use IPFS with their NFTs personally, or using other services as well

1. Sites like https://nft.storage/ (which I dislike as they have a silly bug with content types) or Pinata also got to IPFS.

2. Good point.

Btw you can check: https://nft.storage/

https://ipfs.tech/ combined with https://nft.storage/

Lastly upload your Metadata JSON to Decentralized Object Storage like IPFS, NFT.Storage or Pinata. You may also use a Centralized Object Storage service like AWS S3. Make sure to record the metadata object URI returned from your storage service of choice. We shall use it while minting the NFT.

For just a handful of images (aka manually processing them) you could also use https://nft.storage/

btw I tried on opensea testnet and used nft.storage for ipfs

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
