How it works

wrap is a book written by burning WrapCoin (Wrap). Every word costs something, so every word was meant. Words are ranked by how many dollars were burned to say them, and they fade over a day or so to make room for new ones.

Speak

Write up to 280 bytes, choose how much to burn, and sign with your wallet. The tokens are destroyed for good and your message is recorded on Solana with your address. A burn worth $500 or more at the time becomes a post in the book. Smaller burns are lines in the full record. The smallest burn is 100k Wrap.

You can add an envelope: a short line written on the outside, like "to: the night shift". It is optional.

Knock

Knock at someone's door by burning at their address or .sns name. Every knock shows on their door page. You can also leave them a gift of WrapCoin, up to ten times what you burn. The gift goes to them; the burn is destroyed.

Echo

Agree with something? Echo it. Your burn is added to that word's total and lifts it in the book. An echo can carry a reply or no words at all. Echoes never turn a line into a post: a word is a post only if its own burn was $500 or more.

From inside the envelope (coming soon)

Soon you will be able to speak without your wallet's address on the word. You wrap SOL into Privacy Cash's shielded pool, and later a payment from the pool pays for the burn. The book shows it as coming from inside the envelope.

What is public and what is not

• Every burn, its amount, its message and its time are public and permanent. Nobody can edit or delete them, us included.
• A burn from your wallet shows your address. Anyone can see everything else that address has done.
• When speaking from inside the envelope is available: deposits into the shielded pool are public. What stays private is the link between a deposit and a later withdrawal. A small pool, hurried timing and identical amounts make that link easy to guess. Wait, and use different amounts.
• If you lose the key to your private notes, nobody can recover them.

Fees

wrap takes nothing from a burn: all of it is destroyed, and a gift goes in full to the door. You pay the normal Solana network fee, plus a small one-time rent when you are the first to knock at a door or the first to send it a gift.

Risks

• The wrapbook program and this site have not been audited.
• The program can currently be upgraded by a single key. That authority will be removed after an audit.
• Burns are final. Check the amount before you sign.
• The dollar value is recorded when a burn is indexed. The price of WrapCoin moves; the recorded value does not.
