 Hello everyone, I'm Sean and I'm a software engineer at Airsoft and today we'll be analyzing decentralized exchange liquidity. So since Ethereum was introduced in 2015, the popularity of decentralized exchanges has exploded and as expected many individuals and businesses take advantage, coming up niches. This boom birthed a lot of amazing projects and with true innovation but it also created a saturated market of nexus. So currently there is hundreds of nexus in the wild with most of them in Ethereum and since the source of liquidity for each of these nexus is different, the price can also vary drastically. On average there can be more than a 20% difference in price across nexus. So this makes it very hard to keep track of which nexus has the best price for a different amount of token. So that's why we decided to build a nexus index. Nexus index is a nexus price aggregator that fetches quotes from 13 popular nexus currently and it's powered by an open source JavaScript library that anyone can contribute to and also use for their own projects. But also it's open source so that we don't give any particular nexus an unfair advantage. It also has a clean and simple UI so you can do what you need to do which is buying the best price. As you can see you just select an action, sell or buy, an amount and a token and you'll get a list of nexus with quotes ordered by best price. Using nexus index is very simple. You just import the library and you call main function which would get you the list of quotes given the parameters ordered by best price. You can also look at the documentation to see other features that nexus index provides like the command line tool and since we launched nexus index in January we gained some popularity from over 4,000 unique users from their two countries fetching more than 43,000 quotes from almost 1,200 tokens and we also saw some open source community activity as well. We believe that this growing popularity of nexus index is actually due to a growing issue in the Ethereum community and that is that data needs consolidation. So while diversity and innovation is great and produces amazing projects people still want a consolidated source of data. So what does that tell us? Well the community needs your help to build tools that not only finds the best amongst competitors but one that actually creates a friendly and easy environment for users currently in and entering the Ethereum community. Nexus index can also use our help. We currently have 13 popular nexus integrated but we can always use more whether it be nexus you love and want to see and or nexus you're currently working on. So feel free to submit a pull request and our team will gladly take a look at it.
