hevm VS hardhat

hevm - written in Haskel

However, since we are using a pure Solidity stack, writing tests with ds-test and running them with dapp.tools or foundry, this was a bit more complicated.

There's also jshon which is a simple stack-based DSL for constructing JSON from shell scripts.

http://kmkeen.com/jshon/

It's written in C and is not actively developed. The latest commit, it seems, was a pull request from me back in 2018 that fixed a null-termination issue that led to memory corruption.

Because I couldn't rely on jshon being correct, I rewrote it in Haskell here:

https://github.com/dapphub/dapptools/tree/master/src/jays

This is also not developed actively but it's a single simple ~200 line Haskell program.

It fits into the stack the same way that Hardhat, Truffle, and Dapp Tools do.

I find it insane that much of Solidity code testing is still happening in external languages. I've recently found https://github.com/dapphub/dapptools and that has blown a lot of my confusion away.

Honourable mention would be https://github.com/dapphub/dapptools for those who prefer UNIX-like tooling, but I'd say for the most part Foundry seems to be the better choice now.

Firstly, I'm warning you that I'm going to shill some amazing things in the Ethereum ecosystem. I would even go so far to say as some of these things are so positive sum and self-evidently public goods that shilling them in the ethereum subreddit should be considered neutral. For example, GitcoinDAO is a place where we all have the permissionless ability to coordinate in building tools and services, like dapptools, for all open-source software, full stop. There's ways to fundraise in public besides joining Discord or sliding into Twitter DM's, like Juicebox. There is a plethora of industry leaders exploring decentralized hosting for bluechip-scale applications, such as Skynet.

If you're into CLI tools - https://dapp.tools/

Dapptools is another framework that has nothing to do with JavaScript.

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
