about

unsent museum is a social experiment in permanence. it keeps the things people never sent, forever.

you pay $5, write up to 280 characters, pick a color, and it is sealed on ethereum. it becomes one colored block on a wall that never ends. anyone can read it. nobody can edit it or delete it. not you, not us.

no account. no names, except the first name of whoever it was for. no likes, no comments, no replies. one block, one message, left where it is.

the colors

a color means whatever you want it to mean. nobody is told what you meant.

what happens to your $5

it pays for the ethereum transaction, the checks, and keeping the wall up. messages are written in batches from our wallet, so you never touch crypto.

what gets rejected

links, emails, phone numbers, full names, threats, harassment of a private person, doxxing, sexual content involving minors, spam. anger, grief, love, profanity and confessions are fine. rejected messages are refunded automatically. we don’t say why.

proof

every block links to its transaction. /verify decodes any transaction back into readable messages so you can check the wall against the chain. contract: 0x0000000000000000000000000000000000000000 on sepolia.
