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 🙏

Balancer V2 Pool Utilities

NPM Package Docs

This package contains Solidity utilities for developing Balancer V2 Pools, implementing common patterns such as token decimal scaling, caller checks on hooks, etc.

The most useful contracts are BaseGeneralPool and BaseMinimalSwapInfoPool, used as base contracts for Pools with the General and MinimalSwapInfo/TwoTokens specializations respectively.

The recommended pattern is to create new Pools from factory contracts, as that lets other systems reason about Pool logic by checking if a Pool was deployed from a given factory. BasePoolFactory and BasePoolSplitCodeFactory (for large contracts) can be used for this purpose.

Overview

Installation

$ npm install @aurora-balancer-labs/v2-pool-utils

Usage

Contracts in this package are meant to be used via inheritance to develop new Pools. The BaseGeneralPool and BaseMinimalSwapInfoPool contracts are abstract, meaning some virtual functions (such as _onJoinPool or _onSwapGivenIn) are not defined: derived contracts must override them and provide an implementation.

See v2-pool-weighted for the implementation of Pools with a Constant Weighted Product invariant using these base contracts.
