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.

CrossFuel Snap

CrossFuel is a wallet that employs Account Abstraction to enable cross-chain gas payment with improved user experience.

getConnectedChainId

This function retrieves the connected chain ID of the user's wallet. The function getConnectedChainId() is called to retrieve the chain ID, and the result is returned as a response.

getSignerFromDerivedPrivateKey

This function retrieves the external owned account (EOA) of the user's wallet. The function getSignerFromDerivedPrivateKey() is called to retrieve the signer from the derived private key, and the EOA address is obtained by calling getAddress() on the signer. The EOA address is then returned as a response.

getAbstractAccount

This function retrieves the abstract account of the user's wallet. The function getConnectedChainId() is called to retrieve the chain ID, and the abstract account for the connected chain ID is obtained by calling getAbstractAccount(chainId). The account address of the abstract account is then obtained by calling getAccountAddress(), and the account address is returned as a response.

crossFuel_sendTransactionWithCrossFuel

This function processes both gas payment and actual transaction simultaneously, using a typical transaction object containing payment token information. For a demonstration, please refer to https://github.com/taijusanagi/CrossFuel
