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 🙏

IBC SDK

Tests

The IBC SDK is a powerful NodeJS package designed to streamline cross-chain dapp (xdapp) development using the Inter-Blockchain Communication (IBC) protocol.

Navigate the docs

To run the docs locally at localhost:3000, run:

cd docusaurus && npm start

What does this package do?

The IBC SDK simplifies the development process for xdapps by automating various tasks and providing essential functionalities in only a few API/CLI calls.

Here's an overview of what the package offers:

Automation of laborious tasks

  • Chain Setup Management: Launches multiple chains (dev target chains, e.g. Ethereum, wasmd + the Polymer hub) in separate Docker containers based on a simple configuration.
  • Account Funding: Automatically funds developer accounts for testing and relaying purposes.
  • Off-chain Relayers: Starts off-chain relayer processes to facilitate cross-chain communication and have them monitor the right channels.
  • IBC Connectivity: Establishes IBC clients and connections (configurable) to prepare for cross-chain communication between xdapps.
  • Virtual IBC integration: Deploys the required smart contracts on virtual chains to establish quick and easy IBC integration.

Essential functionality

  • CLI Commands: easy-to-use CLI tool ibctl to cover most use cases, and the ability to exec into the docker containers for more granular control
  • Providing API endpoints: interact with the IBC SDK from your client environment
  • Status Queries: Provides convenient queries for monitoring the status of xdapp ports and messages.

🔋 The guiding principle through all of this?

Batteries included, customization at your service! Start with the default configuration, deploy and get to testing. Customize later.

Who uses this package?

The IBC SDK is designed to cater to two primary user groups:

  1. xDapp Developers: Developers who utilize the IBC SDK to test their xdapps before releasing them on public testnets or mainnets.
  2. Polymer Developers: Developers working on the Polymer Protocol who rely on the IBC SDK to ensure compliance with specifications.

Supported chains

| Chain | Resources | Dev environment docs | | --------------------- | ------------------------------------------------------------- | ----------------------------------------------------------- | | Ethereum | Ethereum Developer Hub | Link | | CosmWasm (Cosmos SDK) | wasmd GitHub | Link |

Note In theory, any Cosmos SDK with CosmWasm enabled can be used. However, an image should be available to list in the configuration file.

Additionally, if you want to connect to a virtual chain through Polymer, the Cosmos chain will have to support multi-hop.

Installation and quick start

Prerequisites:

To quickly get started with the IBC SDK, follow these steps:

Run the npm install command in your terminal:

npm install -g @open-ibc/ibc-sdk

If you prefer to install from source, use the command make and execute it from the root of your workspace.

Warning Windows is not explicitly supported at the moment, although we will gladly accept feedback from brave explorers!

You're all set to go! But maybe you want an example run to showcase a testing workflow? Then go the quickstart tutorials page...

Key Benefits

By leveraging the IBC SDK, developers can overcome several pain points associated with xdapp development and IBC integration. Take a seat and relax while IBC SDK does all the hard work in terms of set-up for you! 🏖️

Here are some of the key benefits:

Simplified Testing Setup

As a xdapp developer, you often face multiple prerequisites when testing xdapps. These include launching supported chains, setting up the hub (e.g. Polymer chain), funding developer accounts, deploying smart contracts, configuring and launching off-chain relayers, and ensuring the correct monitoring of smart contracts and IBC clients.

The IBC SDK simplifies this cumbersome and error-prone process into a single API call, allowing you to quickly set up the necessary environment for xdapp testing.

Streamlined Status Tracking

Tracking the status changes of IBC ports, channels, and xdapp smart contracts typically involves querying multiple processes across different chains and relayers. The IBC SDK offers a unified query entrypoint that consolidates the status information from all relevant sources. This saves time and effort by providing a single interface to monitor and analyze the status of your xdapp components.

Production-Ready Capabilities

The IBC SDK is not only valuable during local development and testing but also offers essential features for (public) testnet and production environments. xdapp developers can continue to utilize the SDK's query API to monitor the status of their smart contracts and IBC packages.

🚧 Roadmap 🚧

  • Starship integration:Starship is similar interchain development tooling, with an initial focus on Cosmos chains. Work is ongoing to integrate the project with the current IBC SDK support.

  • Starting from snapshots: support for bootstrapping from chain snapshots, allowing dapp developers to test their application logic locally against existing state and applications that exist on mainnet.

  • IBC Dashboards: We can leverage the IBC SDK's query API to gather high-level data related to the Polymer Protocol, IBC, and vIBC that's running under the hood.This aggregated data can be visualized in a dashboard, providing valuable insights into the traffic and performance of your cross-chain communication.
