Pay for your npub

No account, no email. Enter your npub and pay a lightning invoice. Anyone can pay for anyone.

02

Add blaastr.com

Put it in your client's relay list next to your usual relays. It only accepts writes.

Post as normal

Signed events from your key go to every relay we know is online, plus your own write relays.

Subscribe or check status

Your subscription belongs to your pubkey. Paying needs no sign-in: only events signed by your key can use it, so paying for an npub is safe even if it's someone else's.
