Global Metrics
Here are the top stats from the last period:
- Total Bitcoin-accepting merchants: 15,306 → 16,284
- Recently verified (1y): 7,540 → 7,803 (the rest of our dataset is slowly rotting; help us before it’s too late!)
- Avg. days since last verification: 398 → 405 (more mappers, please)
- Merchants boosted: 22 (for a total of 4,325 days, someone is feeling generous)

Merchant Adoption
Steak n’ Shake
The US 🇺🇸 is a massive country, yet its BTC Map footprint has been lagging relative to other countries … that is until now!
In what came as a nice surprise to our Shadowy Supertaggers 🫠, the Steak ’n Shake chain began accepting Bitcoin payments across hundreds of its locations nationwide (with some international locations too).
According to CoinDesk, the rollout has been smooth, with users reporting seamless transactions powered by Speed.
This marks a significant step towards broader Bitcoin adoption in the US. Now to drop the capital gains tax on cheesburgers!
SPAR Switzerland
In other chain/franchise adoption news, the first SPAR supermarket in Switzerland 🇨🇭 to begin accepting Bitcoin was this one in Zug. It was quickly followed by this one in Rossrüti and this one in Kreuzlingen, in what is believed to be part of a wider roll-out plan within the country powered by DFX’s Open CryptoPay.
That said, we believe the OG SPAR crown goes to SPAR City in Arnhem Bitcoin City!
New Features
Merchant Comments in the Web App
Web App users are now on par with Android users in that they can both see and make comments on merchants.
This is powered by our tweaked API that enables anyone to make a comment as long as they pass the satswall fee of 500 sats. This helps keep spam manageable and ensure quality comments.
And just in case you were wondering what the number count was on the merchant pins - yep, they’re comments!
Here is an 👉 Example merchant page with comments.
Merchant Page Design Tweaks
To support the now trio of actions (Verify, Boost & Comment) on the merchant page, we’ve re-jigged the design a little to make things a little clearer.
What do you think?
Technical
Codebase Refactoring
Thanks to Hannes’s contributions, we’ve made progress in cleaning-up the Web App’s codebase and completing long overdue maintenance. Whilst often thankless tasks, these caretaking activities help immensely with long-term maintainability enabling us to confidently build new features.
Auth System Upgrades
The old auth system was held together with duct tape and prayers, and we’re working on a more robust authentication system to support future public API access. Updates include:
- Password hashing
- Bearer token support
- Improved security practices
More enhancements are in progress and we’ll update you in the next blog post.
Better API Documentation
Instead of relying on tribal knowledge, we’re finally getting around to writing actual docs (with the help/hindrance of LLMs). The “move fast, break everything” era is over; now we move slightly slower and break slightly less. Progress!
Database Improvements
We use SQLite, which works well but it requires careful handling in async Rust environments. So now we’re untangling this mess to avoid accidental blocking queries (and the ensuing dumpster fires).
Backup System Enhancements
BTC Map data comes in three layers of fragility:
- Merchants (backed up by OS - the big boys handle this)
- Non-OSM stuff (areas, users, etc. - currently stored on a napkin)
- External systems (Lightning node, submission tickets - pray to Satoshi)
We’re now forcing two core members to backup everything, because redundancy is good.
