The words worth keeping.
Folks use it for the big days, the quiet ones, and the words they made up. You pick the occasion and write it your way.
A milestone birthday
“Happy 50th, Dad. Fifty years of bad jokes and good advice. Love, all of us.”

- A certificate to frame. A PDF for Letter, A4 or 11×14, signed with your name, printed at home or at any print shop.
- A page to share. One link that opens on any phone, for everyone who should see it.
- Your words on Bitcoin. Engraved with the date, for good, and checkable by anyone, with or without us.
- A spot in the public registry, numbered, next to everyone else’s.
Don’t take our word for it: every certificate has a transaction ID that opens your words on any public Bitcoin explorer. How to check · See the registry

Good to know.
- No. You pay in dollars by card. You never own or touch any Bitcoin.
- No. Just your words, a card, and your email so we can send your receipt and certificate link.
- Your message is public forever, kind of like words carved on a park bench, so keep private stuff out of it, like a last name, an address or a phone number. The names on your certificate stay private: they show only on your certificate, which opens from the private link we email you.
- No. Once it's saved, nobody can edit or remove it, us included. That's why we show you everything before you pay, and why every message gets an automated safety check first. It can't catch everything, so read your words once more too.
- Your certificate has a reference for your exact entry. Paste it into a free Bitcoin explorer website (we don't run any of them) and your words show up with the date. Some explorers show them as code rather than letters; “See it on Bitcoin” on your certificate page reads the same transaction and translates it for you. That keeps working even if we're gone, for as long as Bitcoin runs.
- When you order, your browser makes a private key, sealed into your message on Bitcoin. The first step on your certificate page saves it as your ownership card (a PDF): we never get a copy. Later, open the card on our proof page to make a proof link that anyone can check against Bitcoin in their own browser. It proves you hold the key, not legal ownership.
- Bitcoin’s fee is usually a dollar or two, and it’s included in the $49. On a rare, extremely busy day we pause new orders for a few hours rather than charge you more. Your message waits on your device until you try again.
