FAQ
Bro questions.
Is Bro safe?
Bro connects two people and was built so trades happen in a simple, fast and private way. Both sides put in sats as collateral: whoever pays the bill keeps their sats reserved until the bill is paid, and every Bro deposits bitcoin collateral before starting to accept bill payment orders. If something doesn’t go as expected, there’s mediation to sort it out.
Do I need to send documents or sign up?
No. Your account is a Nostr key created on your phone. No ID, no email, no phone number.
How much does it cost?
If you pay a bill with bitcoin, there's a 5% fee on the amount. If you're a Bro, you earn 3% on every bill you pay.
Which bills can I pay?
Pix and boleto. Just paste the code or scan the QR.
Does Bro hold my money?
No. The app wallet is self-custodial: only you hold the keys, and you can send your sats to another wallet anytime.
What is Nostr and why does it matter?
Nostr is an open communication protocol. Instead of a central server, orders travel through relays that anyone can run. Nobody can switch Bro off.
What if I lose my phone?
With your 12 words you can restore your account and wallet on another device. Write them on paper and keep them somewhere safe.
