Mira, if you made it to 30, I hope the kitchen still has that yellow kettle. I hope you kept writing even if nobody read it. Please don't be embarrassed by this letter. I was serious.

HOW IT WORKS
Share & Seal.
01 — SHARE
Share.
Write anything — a letter, a prediction, a voice note, a photo. Pick who gets to see it: just you, a friend, or the whole feed. Up to 50,000 characters plus attachments.
02 — SEAL
Seal.
Pick a future date. Sign once. The capsule is encrypted, timestamped, and locked on-chain until that moment arrives — not ten seconds early, not ever by anyone else.
USE CASES
People use capsl to mark time.
