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 🙏

ACTUS Solidity

Build Status License npm version Coverage Status

DISCLAIMER: THIS IS A WORK IN PROGRESS AND NOT AUDITED. USE IT AT YOUR OWN RISK.

Solidity implementation of ACTUS Contract Types (https://www.actusfrf.org/algorithmic-standard)

Demo: ACTUS Solidity Calculator running on Görli Testnet.

Smart Contracts

Core

Contains banking-grade financial logic such as ACTUS day-count & end-of-month conventions, ACTUS datatypes and floating point arithmetic used throughout all ACTUS engines.

Engines

Contains ACTUS state machine engines for each ACTUS Contract Type. An Engine implements the state transition & payoff functions and the schedule generation logic for an ACTUS Contract Type. Engines are stateless smart contracts, thus can be used on-chain as well as off-chain (e.g. by using the EVM as a TEE).

Development

Requirements

  • node: >=10.0.0 <11.0.0
  • npm: >=6.8.0

  • jq (only for generating artifacts)

Note, install truffle and ganache-cli using npm as follows:

npm install -g truffle
npm install -g ganache-cli

Run

  1. install dependencies
# contracts/
yarn install
  1. deploy contracts and run tests
# contracts/
yarn test
