The gift for someone who loves Bitcoin.
Your words, written into it. No crypto needed.
They have the hardware wallet, the books and the opinions. What they don’t have is a line on Bitcoin from someone who loves them.
Write it, pay by card, and it goes into the next block, usually about ten minutes later. They get a certificate to frame, and a transaction they can look up themselves: they’ll know it’s real.

A certificate to keep, and a line that can’t be lost.
- A certificate to frame. A PDF for Letter, A4 or 11×14, 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.
- A permanent record. The line itself on Bitcoin, with its date, checkable by anyone, with or without us.
- Signed by you. The certificate carries the name on the card that pays, and theirs in “In honor of”.
Ways to give it.
You sign the certificate with the name on your card; theirs goes in “In honor of”. The line itself can say who it’s from.
Under the tree
Print the certificate, frame it, wrap it. The transaction ID is the first thing they’ll look up.
“Merry Christmas, Dad. Your words on the chain, for once. Love, Kim”
On their birthday
Send the link in the morning. They’ll open it on their own explorer before breakfast.
“Happy 35th, Leo. Stay humble, stack sats. Love, Mia”
For an anniversary
Put the date you met in the line, and give them the frame.
“Ten years since we met, Ana. My favorite thing on the chain. — R”
Lines a Bitcoiner would love.
“Happy 40th, Alex. Stacking memories with you since 2012. — Sam”
“Dad, you said buy in 2013. We should have listened. Love you.”
“Not your keys, not your coins. But always my heart. — J”
Easy for you, real for them.
01Write one line
About 80 letters: a birthday, an anniversary, an inside joke. A first name or a nickname works best.
02It goes into the next block
We send the transaction and pay its fee. It usually lands in about ten minutes, and stays there for good.
03They check it themselves
The certificate shows the transaction ID. They can open it on any explorer, or their own node, and find your words.
- 10:09
- 10:21

Public, like everything on Bitcoin.
Anyone can read the line, so keep it to first names or nicknames. Your full names stay on the certificate, seen only by people you share your private link with.

What it proves, and what it isn’t.
It proves
- Your exact words are in a confirmed block on Bitcoin
- Anyone can check it, on any explorer or their own node
- Nobody can change or remove it, us included
What it isn’t
- Bitcoin to spend: there’s no coin or token in it
- An NFT or an Ordinals inscription: it’s a plain message in one standard output
For the Bitcoiner: one ordinary transaction with the message in an OP_RETURN output, the place Bitcoin sets aside for a little data. No junk outputs.
Good to know.
No. You pay $49 by card. We send the transaction and pay its fee, so you never touch Bitcoin.
Yes. Your line goes into a real transaction, in a standard OP_RETURN output. The certificate shows the transaction ID, so they can check it on any explorer or their own node.
It’s one ordinary transaction with a short message in OP_RETURN, the output Bitcoin sets aside for a little data. It creates no junk outputs.
You get a private ownership card when you order. Give it to them with the certificate, and they can send anyone a proof link that’s checked against Bitcoin.
No. Once it’s on Bitcoin nobody can change it, us included. Read it twice before you pay.
$49, paid once by card, everything included, Bitcoin’s fee too.
Give them their own line on Bitcoin.
Write it, pay by card. It usually goes into Bitcoin’s next block, about ten minutes later.
