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 🙏

Eternal Proxy Service

The Eternal Proxy Service (EPS) provides an address proxy service on the Ethereum blockchain.

EPS allows users to nominate a hot address to act on behalf of a cold wallet address, together with a delivery address for new assets. This information is held in the EPS register. Smart contracts and applications making use of the EPS protocol can take a hot address and lookup holding information for the cold address.

This has a number of practical applications:

  • Allows users to store assets safely in a cold wallet and interact with smart contracts using a hot wallet of low value. The assets in the cold wallet are protected by interactions all taking place with the hot wallet.

  • This allows users of EPS to prove ownership of assets while not putting them at risk with smart contract interactions.

  • This can be used, for example, in minting NFTs that require an existing NFT to be owned (gated mints), or claiming airdrops based on past wallet activity.

  • Store assets in a cold wallet but have them recognized by applications using the hot address, for example on discord.

  • Have new assets delivered to the desired address first time, through the use of a delivery address. No more shuffling!

EPS is deployed on the Ethereum main network and Goerli testnet.

Import Contracts

This npm package provides three library contracts to implement EPS in your project:

  • IEPSPortal.sol an interface exposing the functions required to query the EPS register.

  • EPSPortal.sol an instance of the IEPSPortal interface using the valid contract address for mainnet and goerli.

  • EPSPortalForTesting.sol as above, but accepts a contract address for us on local chains.
