Kyber Network is a hub for liquidity protocols that collects liquidity from several sources to offer safe and quick transactions on any decentralized application (DApp). Kyber Network’s major objective is to make it simple for users to access liquidity pools that offer the best prices for DeFi DApps, decentralized exchanges (DEXs), and other users.

A greatly transformed business niche that has greatly expanded with Ethereum and DApps is the prediction market. Prediction markets are decentralized exchanges where the objects of trade are not stocks and bonds but the results of various events. It can be like a decentralized sports betting exchange, which used to bring its owners a fortune, and with the arrival of DApps, several fortunes at once. Examples of popular DEXs are Uniswap, Curve, Balancer, SushiSwap, DODO, Bancor, and Kyber.

The next altcoin is the Kyber Network Crystal, a multi-chain liquidity hub. It seems that KNC held its own throughout this consolidation phase of the market. When the rest of the market was deflating, it was surging. In the $3.50 to $4 price range, it’s about to reach an extremely hazardous area. As in early 2021, this massive supply zone has already been reduced.

In 2019, investors were introduced to the first wrapped Bitcoin product, WrappedBTC (wBTC). The creation of wBTC by BitGo, Kyber Network, and Ren, formerly known as Republic Protocol was revolutionary in its own right, but wBTC is entirely centralized due to BitGo being the sole custodian for wBTC and this entity, partly owned by Goldman Sachs, has full legal control of all locked Bitcoin wrapped in wBTC.

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.
