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 🙏

Polymarket Notifier

This app continuously monitors UMA Optimistic Oracle contract proposals and sends notifications based on Polymarket API information.

The Polymarket notifier looks for ProposePrice events related to the Polymarket contracts and uses the Polymarket API to fetch all active contract market prices. It compares proposed prices against the Polymarket API and notifies the user through a logging mechanism that can forward an alert to Slack or any other configured transport mechanism. Notified proposals are stored on Google Datastore, so on repeated runs the application does not notify the same proposal.

Environment variables

The Polymarket notifier uses the following environment variables:

  • CUSTOM_NODE_URL is a Polygon (chain id 137) network node endpoint.
  • NOTIFIER_CONFIG is a JSON object containing-application specific parameters:
    • minAcceptedPrice determines if an alert should be sent at the time of a proposal based on the price value returned from the Polymarket API. The default is set to 0.99, meaning when a price is proposed it requires the API price to be greater than 0.99 or an alert will be sent.
    • minMarketLiquidity Minimum market liquidity that determines if alert is sent.
    • minMarketVolume Minimum market volume that determines if alert is sent.
    • apiEndpoint sets API to fetch Polymarket contract information, defaulting to https://strapi-matic.poly.market/markets
  • POLLING_DELAY is value in seconds for the delay between consecutive runs, defaults to 10 minutes. If set to 0 then running in serverless mode will exit after the loop.
  • BOT_IDENTIFIER identifies the application name in the logs.
  • ERROR_RETRIES is the number of times to retry failed operation (e.g. due to API not responding). It defaults to 3 re-tries on error within the execution loop.
  • ERROR_RETRIES_TIMEOUT is time in seconds between re-tries, defaulting to 1 second.
  • SLACK_CONFIG is a JSON object containing defaultWebHookUrl for the default Slack webhook URL and escalationPathWebhookUrls being an object with webhook URLs for particular Slack channel routing.
  • GOOGLE_APPLICATION_CREDENTIALS points to Google Cloud Platform service account key file to access Google Datastore. This is only required when running the application locally.

Running expiring contracts notifier

The simplest way to run the Polymarket monitor bot is from UMA protocol repository run (if running locally, make sure you have GOOGLE_APPLICATION_CREDENTIALS as an environment variable):

CUSTOM_NODE_URL=https://your.node.url.io yarn polymarket-notifier --network polygon-matic
