Buy and sell bitcoin by paying bills.
P2P, no KYC, built on Nostr.
Our new site is live, with:
→ How Bro works in 4 steps
→ How to set up your BRIX
→ How to become a coordinator
→ Every app update in one place
👉 brostr.app
🛠️ Just released: build 742
Instant alerts for Bros and one more relay
⚡ Bros get notified the moment the bill code arrives. Before, it could take minutes.
🏁 Clearer screens when two Bros take the same bill: the app shows who won and what happens next.
🤝 Dispute mediations now pay the Bro automatically when they have a BRIX.
📡 A new relay of our own is live, so the network doesn't rely on a single one.

Great conversation between @carol_bitcoin and @Breez_Tech. Give it a listen 👇
"It wouldn't be possible to exist Bro if it wasn't for Breez." — @carol_bitcoin
From the dentist's chair to 600,000+ followers learning about magic internet money with @areabitcoin.
Carol Souza is helping the next generation of Latin Americans use bitcoin as money, not just something to trade. That's why she built Bro: pay any bill in Brazil with bitcoin, peer to peer, with no exchange and no KYC.
The wildest part of her story is how she built it. A former dentist with no dev background, she shipped @bronostr with the Breez SDK and turned "months of work" into weeks.
Learn more about how she did it in episode 12 of Shoot the Breez:
