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.

Sample Transactions

Sample token contract address is bc1plhz9wf0desgz8t32xm67vay9hgdmrnwzjzujgg0k9883cfxxgkzs20qfd5

A transaction with 2 token UTXO inputs and 1 token UTXO output, with a virtual size (vsize) of 3.9k. The transaction ID (txid) is 2537706ed1000d5dd3a28d79a95ade8f674fd3e25c020cbcf97fd1b1e86ec8ef.
A transaction with 1 token UTXO input and 2 token UTXO outputs, with a virtual size (vsize) of 2.6k. The transaction ID (txid) is 94e3254c1237ba7cd42eaeeae713c646ee5dd1cd6c4dd6ef07241d5336cd2aa7.

CAT Token Transaction Limits

For a CAT Token protocol transaction, the maximum number of inputs is 6, and the maximum number of outputs is also 6.

Since we need to calculate the txid of the previous transaction, we must ensure the previous transaction’s data is within 520 bytes.

This is because the maximum byte limit for an element on the Bitcoin Virtual Machine (BVM) stack is 520. The corresponding constant name is MAX_SCRIPT_ELEMENT_SIZE.
