VIII EDITION · FREE BEER FUND
Fill the glass.
Send some sats.
100% of your sats turn into cold beers in our hands.
Every sat you send via Lightning goes straight back to the community as ice-cold free beer at our next conference. No middlemen, no fees kept. Scan → Pay → watch the glass rise in real time.
With every donation you can leave a short message that appears on our Wall of Foam — your personal shout-out for the whole crew to see. The more sats we stack, the more free beer flows.
Let's get this glass overflowing. Thanks for your support!
Donate in two steps
- 01 Open your Lightning wallet & scan the code
- 02 Pick an amount, leave a message + name in the comment field — or stay anonymous
Every sat goes straight into the beer fund — nothing skimmed, nothing kept. Comment support varies by wallet; Muun and a few older apps don't show it.
*a rough estimate, based on the rigorously scientific exchange rate of 1 beer ≈ 3,000 sats.
A Tradition, Not a Gimmick
Every Edition, a Round on the House.
Wall of Foam — every name here bought someone a round
Not a single sat in the barrel yet. Be the first.
Can't make it to Mallorca?
Send some sats!
Send a few sats from your couch, your office, or wherever you are in the world — and somewhere in Mallorca, a stranger raises a glass thanks to you and the power of bitcoin. Your name goes straight onto the Wall of Foam, and for the price of a coffee you just made someone's whole conference a little better. Muchas Gracias!
