Write your message into the blockchain.
Keep it forever.
A keepsake no fire, flood, or forgotten password can ever take away. Readable by anyone, erasable by no one.
How it works
Three steps to forever
Write
Compose your 300 characters and watch them take shape on beautiful stationery — choose the paper, choose the hand it's written in.
Inscribe
After a simple card payment, we write your full letter into a Bitcoin transaction. No wallet, no crypto knowledge — we handle the chain.
Share forever
You receive an elegant page to share, linked to the transaction itself — proof that your words live on the blockchain.
Why Bitcoin
“Paper burns. Photos fade. Companies shut down. The Bitcoin ledger is copied across tens of thousands of machines in every corner of the world — and it has never lost a single word entrusted to it.”
Your letter is stored in the transaction itself, not on our servers. Anyone can open it on a public block explorer and read your words back out of the raw data — no account, no permission, no us.
Questions people ask
- What is Sealed Forever?
- We write your letter, word for word, into a Bitcoin transaction — the most permanent public record there is. You get a page to share, and proof on the blockchain that anyone can check.
- Do I need a crypto wallet, or to know anything about Bitcoin?
- No. You pay by card and we handle the chain entirely. You never touch a wallet, an exchange, or a seed phrase.
- Who can read my letter?
- Anyone. A letter written into Bitcoin is public by nature — that is what makes it permanent and verifiable. Write it as something you would be glad to have found, not as a secret.
- Can it be edited or deleted later?
- No, and that is the point. Once inscribed, your letter is carried by thousands of independent computers around the world. Nobody can alter or remove it — not us, not you.
- What if I make a mistake?
- Check it before you pay. You write and preview your letter first, and nothing is sent to the blockchain until the payment goes through. After that a typo is permanent, so take the extra minute.
- How long does it take?
- The transaction is broadcast within a minute or so of paying, and your shareable page works straight away. It is usually written into a block within the hour.
Not today?
We'll remind you when it matters.
Tell us the date it falls on — an anniversary, a birthday, the day you met — and we'll write to you about ten days before, in time to get the words right. One email. Nothing else, ever.
