Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Mochi API

API that powers Mochi Finance.


To Run

Optional enviroment vars:

BSC_RPC - A custom RPC endpoint that you want to use. HECO_RPC - A custom RPC endpoint for HECO. You can just leave the default one otherwise. FORTUBE_API_TOKEN - A token from Fortube to use their API. If you don't have a token you will get a console warning and the Fortube APYs will be slightly smaller than in production. Everything works fine otherwise.

Afterwards just do

yarn install-all
yarn start


Endpoints


Consumed by the app

/apy

The main endpoint used by the frontend. It returns the APY of all the vaults in the following format. This is the legacy format. A new endpoint is being created at /apy/breakdown with a staggered migration.

{
	"bifi-maxi": 0.22448469479728606, // 22%
	"cake-cake": 2.8002377054263174, // 280%
	"cake-smart": 2.8002377054263174, // 280%
	"cake-swingby-bnb": 21.85102752680053 // 2185%
}

/apy/breakdown

The new version of the APY endpoint, broken down into component parts when they are available. The endpoint moves to a new format, which is consistent whether or not the breakdown stats are possible to display. It has the following structure:

{
  "bifi-maxi": {
    "totalApy": 0.07598675804818633
  },
  "cometh-must-eth": {
    "vaultApr": 1.186973388240745,
    "compoundingsPerYear": 2190,
    "mochiPerformanceFee": 0.045,
    "vaultApy": 2.1057844292858614,
    "lpFee": 0.005,
    "tradingApr": 0.22324214039526927,
    "totalApy": 2.8825691266420788
  }
}

As you can see above, the endpoint attempts to expose some elements from the breakdown of the Total APY calculation. Where this is not possible, we just show the legacy Total APY. Note that the legacy Total APY -> totalApy does not include the trading fees.

Each of these fields within the structure are:

  • vaultApr - Yearly rewards in USD divided by total staked in USD.
  • compoundingsPerYear - The estimated compounding events. This is an internal field and references the value used within the calculation for this project.
  • vaultApy - The vaultApr compounded, using compoundingsPerYear and mochiPerformanceFee in the calculation.
  • lpFee - The Liquidity Provider (LP) fee per trade. This is an internal field for reference.
  • tradingApr - Annual interest from trading fees, not compounded.
  • totalApy - The known Total APY. Where fields are available to calculate the Total APY including trading fees, this is calculated. The final calculation is totalApy = (1 + vaultApr) * (1 + (compounded tradingApr)) - 1.

After you start the API it can take a minute or two before you can fetch the APYs. We currently log getApys() to the console when all the data is available.

/prices All token prices under the same endpoint (crosschain).

/lps: All liqudity pair prices under a single endpoint (crosschain).
