Canister Guide

A graduation time capsule for the walk across the stage

Seal encouragement, memories, and advice that unlocks on graduation day — or years later when the diploma is on the wall.

Mark the end of one chapter

Graduation is a natural time-capsule moment. Students and parents alike use Canister to capture pride, uncertainty, and hope — then open the message when the next chapter proves what mattered.

For students and families

Graduates can write to their future selves about first-job fears. Parents can seal a letter to open on commencement morning. Both use the same encrypted, on-chain capsule model.

Signature supports up to five files; Legacy up to ten. Encryption happens in your browser before anything reaches the Internet Computer.

Common questions

Can I unlock on high school and college graduations separately?

Yes. Create one capsule per milestone with its own unlock date and access key.

Is this good for a class gift?

Groups can each contribute individual capsules or one organizer can compile messages — each sealed capsule is independent.

What is the longest unlock horizon for a graduation gift?

Legacy supports unlock dates up to 50 years ahead — useful for parents planning while children are young.
