NIP-05 name store

What you are buying

A record in satoshi.si/.well-known/nostr.json that maps your chosen name to your nostr public key. Anyone can then look up you@satoshi.si and get your key: a short, human-readable, domain-verified identifier instead of a long npub.

Prices

• 3 characters — 50.000 sats
• 4 characters — 21.000 sats
• 5 or more characters — 5.000 sats
• One and two character names are not for sale: they are being held back for a much more expensive tier.

One-off payment, no subscription, nothing to renew. The price you see while typing is the price the invoice is made from — both read the same list.

Rules

• One key, one name. A public key that already has a name here cannot buy a second one. If you are buying for the key you already registered, use a different key.
• 3 to 30 characters: letters, digits, dot, dash and underscore, starting and ending with a letter or digit.
• Names are stored in lowercase: Alice and alice are the same name.
• Brand names such as bitcoin, satoshi and lightning are reserved — write to one@satoshi.si if you want one.

Paying

• Three ways, whichever suits you: Lightning (a BOLT11 invoice), on-chain (a fresh address per order) or Ark.
• The name is written to the public file only after the payment settles. There is no "pay later" and no half-finished state.
• An order holds the name for you while you pay. If it expires, the name is released and can be bought by someone else.
• The page updates itself — you can close it and come back, and it will still show your order as long as the link is alive.

After it is registered

• Your key may write to wss://nostr.satoshi.si. Access rules are synced from this name file and can take up to an hour to reach the relay.
• Check it yourself any time: satoshi.si/.well-known/nostr.json
• Your private key is never asked for, never transmitted, and never stored here. If anything ever asks you for it to buy a name, that is a scam.

If something goes wrong

If a payment settles for a name that was taken in the meantime, it is handled by hand: write to one@satoshi.si and you either get the name or the sats back. Questions about a specific order: one@satoshi.si.
