[ANN] MakerWatch.space - A New Physical Bitcoin Tracker & API (Early Release)

[hybridsole]

MakerWatch.space
Tracking physical bitcoins and crypto-collectibles on the blockchain

Hello everyone,

I am excited to announce the early release of MakerWatch.space, a new tool designed to monitor the status, funding, and activity of physical crypto-collectibles.

As collectors, we know that tracking the history of these coins is vital. While we have had excellent tools in the past, many have gone offline or are no longer maintained. My goal with MakerWatch is to provide a modern, community-driven dashboard that makes it easy to visualize collections, track "peeled" coins, and get notified of blockchain movements in real-time.  MakerWatch is free software and is provided "as is" without warranty of any kind.

PLEASE NOTE: This is an early release. Features are still being added, and I am actively looking for feedback and missing address lists.  There is a very easy to use feature for adding additional coin releases described below.  


Key Features

• The Watchlist Dashboard: A high-level view of the physical crypto market, tracking Total Locked Value (TVL), active spending, and treasury stats.
• Real-Time Event Feed: The system monitors blocks for activity. If a tracked coin moves funds, it appears on the dashboard immediately.
• Priority Alerts: The system automatically flags "Severity High" events, such as when a series loses significant funding (peels) in a short period.
• Makers Gallery: A visual index of makers and their series. You can sort by release date, funding amount, or recent activity.
• Smart Search: Quickly search by Bitcoin address or Serial Number to find which collection a specific coin belongs to.

--- Dashboard Preview ---

The main view showing the coin carousel and summary stats.

For Developers & Automation

One of the core focuses of MakerWatch is open data. You don't need to refresh the website to stay updated.

• Telegram Channel: Subscribe to the official MakerWatch Feed on Telegram to get instant notifications on your phone or desktop for every new transaction and priority alert.
• RSS Feeds: We provide a public RSS feed that includes both transactions and priority alerts. You can plug this directly into a Discord bot (like MonitoRSS) to get a ping in your server whenever a physical coin is peeled.
• Public API: JSON endpoints are available for developers to fetch recent events or query specific collections.

For full documentation and endpoint URLs, please visit the API & Tools section of the site.


Visual Gallery & Inspection

You can drill down into specific releases (e.g., Casascius Series 2) to see a breakdown of Funded vs. Peeled coins. The interface supports filtering to quickly identify empty addresses that were previously funded.

--- Collection View ---

Detailed view showing funded status and serial numbers.

How to Submit a Collection

If you have a list of addresses for a Maker or Series not yet tracked, please submit it!

I have built a submission tool that allows you to paste raw text lists. The system will automatically parse out Bitcoin addresses and serial numbers and let you preview the data before sending it for review.  Once submitted, I can activate the collection with just a couple of clicks on the back-end.

Link: Submit a Collection

--- Submit Collection ---

Simple collection submission interface that parses addresses/serials.

Credits & Inspiration

I want to express my appreciation to those who laid the groundwork for tracking physical crypto:

• Raghav Sood: His work on Collectible.money was the gold standard and the primary inspiration for building this version.
• Minerjones & the Bitcointalk Collectibles community: For their work on Bitcointalk maintaining lists, organizing history, and keeping the community safe.
• Naypalm (uberbills) & Anduck (anduck.net) @ Melik's Cas Tracker: For providing and maintaining additional tools that have provided several years of valuable tracking information for Casascius and BTCC.

Please let me know what you think! Bug reports and feature requests are welcome.  I am also open to collaborators who would like to serve as a 'contributor' role, and I can grant access to curate and maintain collections.  If you are interested, just send me a message.

MakerWatch.space Changelog

This post will serve as a running log of updates, new features, and bug fixes for the MakerWatch platform. As this is an early release, expect frequent updates as I refine the detection logic and add new address lists.


Current Version: v1.0.0 (Early Access) Release Date: December 2025

[Kryptowerk]

Awesome work, first look and feel of the website is very smooth!

I think you can relatively easily scrape the Moonbits data from here: https://github.com/LIMXTEC/MoonBits


One question: Is it / will it be possible to have a personalized dashboard to track (your own) funded items?

Thanks KW!  Great suggestion on the dashboard. I have added a 'My Watchlist' feature that lets you tag any address to be part of the watchlist, and made it exportable/shareable. 

Quick question on the Moonbits data: I was able to extract a few series from those TXID's, but in some cases the TXID covers multiple series. For example, the 2018 TXIDs contain 1000 UTXOs, and 800 of those are part of the "1k Bits Silver Finish series". But for the other 200, it's not clear to me which series they belong to.  Is there any resource that shows the serial number side by side with the address?

[cygan]

@hybridsole really good work... a worthy successor to raghavsood's Collectible.money!
i will of course add all Icarus editions with all the necessary information to the maker overview

have now also used the search function and unfortunately found that the search via the serials does not work for eg. Satori and Moonbits... will this be fixed?

[YodasRedRocket]

Nice work my friend! If I had any merit to send ya I would ✌️

I think the other 200 tx were for unreleased test coins (maybe used as gifts etc.).

You gave me this test link: https://makerwatch.space/?wl=1ECbuRVtV2f8qyWWVjhC6Ns4ArQcFPoyhy,13hVGusSCfKgsREa2nMZGsmGWhRiNzkNJi#watchlist
It does not display any coins for me.

It would be really great to utilize your website for tracking your own collection.

These are now fixed! It was missing the leading 0's from the Satori serial #'s, so those should be searchable now.  Thank you for being the first to use the 'Submit' feature, it really makes things so easy.  There is now an edit feature as well that anyone can use to suggest edits or post updated pictures.

Thanks! I'll work on getting these additional series added soon.

You gave me this test link: https://makerwatch.space/?wl=1ECbuRVtV2f8qyWWVjhC6Ns4ArQcFPoyhy,13hVGusSCfKgsREa2nMZGsmGWhRiNzkNJi#watchlist

It would be really great to utilize your website for tracking your own collection.

I should have mentioned after I sent that link to you, I changed the format of the shareable watchlist links.  Rather than use full addresses which result in huge URLs for 100+ addresses, it now uses a shorter ID for each address.  Here's an example of the new exported watchlist format: https://makerwatch.space/?ids=2182,2090,2184,2080#watchlist

Clicking that link will give you the option to import those addresses into your own watchlist, or keep it as a 'read-only' watchlist.

[cygan]

i've finally done it and added all Icarus editions that are or were available for sale on Makerwatch, along with all the information and images. the only thing missing are the images for the two Hat editions: https://makerwatch.space/#maker-Icarus



@hybridsole it would be great if there was an option to see a complete overview for each maker of the total number of loaded addresses so that you could see how much Bitcoin is held in total on the collectibles

[aoluain]

Great site, very useful!

Would you consider making it  an option to have a link from each collectible to a site elsewhere i.e this Collectibles board?

I just noticed that on the AlpenCoin listing BF135 is not listed [I have it!]?

Great job on adding all the series, cygan!  It has saved a ton of work on my part, and also ensured the series are accurate.  I love the maker summary statistic suggestion as well, and have placed summaries for all makers on the main makers page: https://makerwatch.space/#makers 

And additionally there are now dedicated pages for each maker, like this one: https://makerwatch.space/#maker-Icarus

Another great suggestion!  This is now available on any series/collection page for each address. You can copy either a direct link or a forum embed link. 

Here is what the embed would look like on the forum:

MakerWatch Report
    AlpenCoin - Custom Buyer Funded
   

Serial #	Bitcoin Address	Balance	Last Activity
BF135	1MK6couLQ9xj4yy1jw34tW8dZQmZdkjxz4	0.0005 ₿ $45.79	4 yrs ago

I am not sure why but your serial # was the only one that didn't get picked up when I added the series    But it's in there now. 

[cygan]

@hybridsole thank you very much for implementing my idea so quickly, that's exactly what i had in mind!
i also find aoluain's idea very interesting, and you implemented it very well... i really like the forum bbcode

[Kazkaz27]

Now this will be spectacular for the community🤍⚡ Amazing Work!

yes that works for sure, nice feature

but

what I was aiming at was the reverse really.

to

the relating page in BCT: https://bitcointalk.org/index.php?topic=5570396.0 for anyone
to get more info regarding a particular piece.


... and thanks for the serial # addition

[DOBLEBIT]

Thanks for sharing this, it looks really good 👍
We’d love to be included in the tracker.

In our case, on https://doblebit.org
We’ve integrated something similar directly into the site: each artwork includes a small on-chain tracker showing the associated public Bitcoin addresses and their funding status.

Onchain verification and transparency are very important to us, so it’s great to see initiatives like this.

Nice work!

Oh yes, that is an easy thing to add via the 'edit' link on the series page.  It would just need to be added to the 'Description' section, which I have just done for that particular series.

Thanks Doblebit!  I actually do have a few Doblebit series added so far.  https://makerwatch.space/#maker-Doblebit

One thing I noticed is that, of the three Doblebit series we are tracking, you have 100% funding rate (zero peels) which is very impressive.

@hybridsole are the stored BTC addresses for the respective makers/editions checked again at certain intervals to see whether they have been funded or peeled?
if so, at what intervals does the repeated scan take place?

Yes, there are 2 ways the site will scan addresses.  The first way is the "full" scan which checks an address for current balance and any spending transactions. This is done in small batches every few minutes (with newly added or oldest addresses first) to not overwhelm the public API providers. The site rotates through about six different API providers.

The second scan is a "block" scan that also runs every few minutes. It downloads the 2 most recent blocks added to the bitcoin blockchain and checks to see if these blocks contain any of the addresses we know has a balance (from the first scan). This is where most of the real time peel events are detected.

I am looking for ways to avoid relying on public API providers because they can ban my IP at any time and make the site mostly useless.  If someone here is hosting a full node with an accessible endpoint, let me know!  I am also thinking of standing up my own full bitcoin node but haven't gotten around to it. 

[cygan]

hmm, okay
but could it be that the entire process/scan is not yet working 100%?
because, as you can see here, all 21 cards from this series were loaded on january 11, but MakerWatch shows that the last scan was 9 days ago and therefore the amounts are not yet displayed: https://makerwatch.space/#series-158
