Preserve your wedding vows on Bitcoin.
Not the whole speech. The line you want to keep.
Vows get said once, in front of everybody, and then mostly live on in a video that’s hard to find.
Pick the line that matters most and engrave it on Bitcoin. It becomes a permanent record with a date nobody can change, plus a keepsake certificate to frame and a link for the people who were there.

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.
Whoever pays signs the certificate with the name on their card. The couple’s first names belong in the line.
The two of you, on the day
One of you signs; the other goes in “In honor of”. Send the link to everyone who was there.
“You, me, and every ordinary Tuesday after this. — Nia & Leo, 2026”
A gift from a guest
You sign it as the giver; the couple goes in “In honor of”. Tuck the link into your card.
“To Nia & Leo, married June 6, 2026. May it always feel like today. — Kim”
Renewing your vows
Engrave the new promise next to the old date. Frame it next to the wedding photo.
“Said yes in 2006. Said it again in 2026. Still mean it. — Ann & Raj”
Lines worth keeping.
“With this word, I bind my life to yours. — Elena & David, June 2026.”
“I'll still pick you, on the easy days and the hard ones. — Sam & Jo, 2026”
“Twenty years ago we said yes. Today we said it again. — Ann & Raj”
How your vows are kept.
01Pick the line
Up to 80 plain letters, about one sentence. First names and the date work well. Leave off last names, since the words are public for good.
02It joins the next block
About every ten minutes Bitcoin adds a block, stamped with the time. Your vow usually goes into the next one, and that block’s time is its date.
03A keepsake to frame
You get a certificate to print and frame, and a link for family and friends. The transaction ID opens your words on a public Bitcoin explorer.
- 10:09
- 10:21
- 10:31Your vow
- 10:42
- 10:50
The words are public. The names on the certificate aren’t.
Anyone can read your vow, for good. Full names on the certificate aren’t on Bitcoin or the public page, only on your private link, so first names in the vow are plenty.
Public anyone can see it
The Vow
“With this word, I bind my life to yours. — Elena & David, June 2026.”
These words go on Bitcoin, for good.
Private only via your link
- Signed byDavid Hollis
- In honor ofElena Hollis
- Emaildavid@example.com
What it proves, and what it doesn’t.
It proves
- These exact words existed by that date
- Nobody has changed a letter since
- Nobody can take them out, not even us
It doesn’t prove
- That you’re legally married
- That you’ll keep it. That part’s up to you.
An engraving isn’t a marriage record. Your license and certificate still come from the county or the state.
Good to know.
Nobody can honestly promise forever. What we can say: once your line is on Bitcoin, nobody can change it or take it out, us included. Bitcoin has added blocks every day since 2009 and is copied on thousands of computers, so your vows don’t depend on us or any website staying around. As long as Bitcoin runs, they stay put.
No. 80 bytes is about one sentence, so pick the line that matters most. Plain letters, numbers and spaces count as one each; accented letters count as two, emoji as up to four.
First names are nice, and they’re public for good. The names on your certificate aren’t on Bitcoin or the public page; only people you share your private link with see them. Leave out last names, the venue and anything you’d rather strangers didn’t know.
Either. The date on Bitcoin is the day you engrave it, not the wedding day, so if the day matters, put it in the words: “June 14, 2026.”
No. It’s a dated public record of your words, nothing more. Your marriage license and certificate still come from the county or the state.
It’s a unique one, and it takes up no room. For now the certificate is signed with the name on the card that pays. Forward the private link from your order email to the couple, and they can print and frame it.
Yes. A line from your vows works on any anniversary, or write a new one for a vow renewal. It makes a wedding anniversary keepsake you don’t have to dust.
No. Once it’s on Bitcoin nobody can change it or take it out, not even us. Read it twice, out loud if it helps.
$49, paid once by card, everything included, Bitcoin’s fee too. You get a link to share and a certificate to print and frame.
Say it once more, for good.
Pick your line, pay by card. It usually goes into Bitcoin’s next block, about ten minutes later.
