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 🙏

Umbrella core overview

Umbrella is an upgraded version of the Aave Safety Module, based on a staking and slashing mechanism. The primary reserve coverage asset is an aToken wrapped in a waToken (StataTokenV2). However, assets not directly connected to the Aave ecosystem (such as various LP or staked/restaked tokens) may also be utilized. This system employs a series of contracts designed to semi-automatically address reserve deficits while providing additional rewards to StakeToken holders.

Umbrella key components

The Umbrella system comprises three main components:

  • Umbrella: The central contract that orchestrates the system and serves as the entry point for addressing deficits through the slashing mechanism. It incorporates logic for estimating required funds to cover debt, managing system configurations, and creating new StakeTokens. The Umbrella contract is connected to each Pool across all networks to monitor reserve deficits and semi-automatically mitigate them when they occur.

  • StakeToken: An upgraded version of the Aave Stake Token, responsible for holding reserve assets. These assets can be slashed to cover deficits. Each StakeToken maintains an exchange rate tied to its underlying assets, which adjusts based on slashing events. The StakeToken is integrated with the reward system via a hook and the RewardsController contract. Additionally, it includes logic for fund withdrawals through a cooldown mechanism. For each market protected by the Umbrella system, one or more StakeTokens will be created.

  • RewardsController: A revised contract designed to allocate incentives to StakeToken holders. It facilitates the distribution of rewards and manages the claims process for these stakeholders. The contract supports the distribution of multiple types of rewards (up to eight in the current implementation) and operates as a single instance per network.
