forever memoriesa little home for your story

For your people. For your someday.

For all the days
you’ll want to
go back to.

The belly laughs. The tiny hands. The ordinary
afternoon that turned out to be everything.
A private photo book for a life you love.

Just for you, and the people you let in.

A father holding his child in the sea at dusksafe in your arms
the good old days,
while they’re happening.
A little helping hand in the kitchena little flour, a lot of love
Go on, open it
A home for photographs, little films, and all the feelings in between.↓
Opening your memory book…
A quiet moment between a father and child
If only we could bottle this feeling.

A note for your future self

One day, these will
be the big things.

You won’t remember what was on your to-do list.
You’ll remember the way they laughed.

Give those moments a place of their own. Tuck in a photo. Add a few words. Keep a little film with their voice in it. Come back, turn the pages, and feel it all again.

Private, until you invite someone in.A book you can take with you.

Made to be held onto.

Who can see my memories?

Your photos, videos and captions are encrypted on your device before they are saved to Koinos. Only your keys, and the accounts you share with, can open them. Addresses, sizes, timing and sharing relationships remain public.

Can I take my book with me?

Yes. Save this HTML app and your password-protected recovery kit. Open the file from another host or your computer and restore your book directly from a Koinos node. Keep your recovery kit and password safe; your wallet alone cannot recover the encryption keys.

Can someone I love have a copy?

You can give another registered account access to your entire book, including future memories. That access is permanent. They can read your memories, but they cannot use your wallet or add memories for you.

A little room for more memories

One vUSDC or vUSDT adds 100 credits. Keep them for your own book, or buy them as a gift for someone you love. Credits stay with the receiving wallet. Long-term access depends on Koinos, available nodes, and keeping your recovery keys safe.

Your story has a home here.

Keep your story safe.

Choose a strong password. Your recovery kit is the only portable backup of your private encryption keys. Wallet connection alone cannot restore them.

Let’s keep this little moment.

About your prepared memory

Choose a memory to see its exact credit cost.

Five size levels: 1, 2, 4, 7 or 10 credits per photo or started second of video. Credits are spent when your upload begins; you can resume an interrupted upload without paying again.

For all the moments still to come

A little room for more.

Add credits to your own book, or give someone you love a place to keep their memories.

100 credits cost 1 vUSDC

Any amount, down to 0.000001 credit. One vUSDC or vUSDT buys 100 credits. Your wallet needs mana to make the purchase.

Some stories are better together

A place for your people.

This gives another account read access to all your existing and future memories. They must create their own gallery first.

People with access

Behind the pages

Your book’s connection.

Must run Koinos mainnet. The public koinvault.app currently runs mainnet. Vault pairing requires an HTTPS page; local wallets and recovery work from this HTML file.

For local wallets and Kondor. The current Koin Vault adapter uses the wallet’s own mana. Purchases always use your wallet’s mana. Public pool capacity is limited and may be exhausted.

A sponsor address must already have a contract that authorizes these transactions. An ordinary funded address cannot sponsor without its signature.

Chain and contract

No app backend is needed. Public RPC nodes and wallet providers are replaceable connections.
