on the day.

Write a note, attach a small file, tuck in some ETH or a token. Pick the day it opens and, if you like, the one wallet allowed to open it. The gift stays locked in the contract until then. Nobody claims it early. Not even you.

CORE SAMPLE · YOUR CAPSULESSURFACE = TODAY
01 / write

Say the thing

A message and a small file, encrypted in your browser with AES-256 before anything leaves it.

02 / bury

Pick the day

Lock it to a date, up to 100 years out. Add a recipient wallet if only they should open it.

03 / wait

Let it sink

The capsule drifts down through the layers as its day gets closer. It is an NFT you can watch.

04 / unearth

It surfaces

On the day, the holder opens it, reads the letter and pulls the gift into their wallet.

Why seal it onchain

A promise that keeps itself.

contract

No early opening

The unlock date lives in the contract. Not the sender, not us, nobody can pull the gift out before it.

privacy

Encrypted first

Your letter is sealed with AES-256 in your browser. The chain only ever holds ciphertext and a hash.

gifts

ETH or tokens

Tuck in ETH or any ERC-20. The holder claims it in one transaction once the day arrives.

ownership

It is an NFT

Each capsule is a token you can hold and watch sink. Recipient-bound ones stay put until they open.
